    DB:4.79:Sdelete For Space Reclaimation k1






    Hi,

    We are upgrading to esxi5.5, and we are having thin provision vmdk.

    We want to use space reclamation in our env and our array doesn't support it.

    On ESXi level, we are planning to using sdelete using vmkfstools for space reclamation. I want to know ,what kind of risk involve in space reclamation using sdelete and what kind of cautious measurement we need to take while using sdelete.

    We are planning to use this option in production.

    DB:4.79:Sdelete For Space Reclaimation k1


    `sdelete -z` will zero out the space on your Windows guest's volumes by creating a (hidden) file called SDELTEMP on the destination volume and filling it with zeros until the volume runs out of space. Thus, it is functionally equivalent to `dd if=/dev/zero of=/zerofile; rm /zerofile` commonly used on Linux platforms for this purpose. You only should do this on guests where either a brief out-of-space condition is not an issue to the running application set or where you can schedule a downtime for the process. As the amount of zero data written may be quite large, it might be difficult to exactly predict when sdelete's zero file is going to create disk space shortage to impact applications.

    As the `sdelete -z` run is going to inflate the thin virtual disk to its maximum configured size, you need to make sure the VMFS datastore the disk resides on does indeed have enough space to accommodate the inflated virtual disk. You also should delete all snapshots you have created for the virtual guest in question beforehand. Last but not least, do take the additional I/O strain on your disk array into account - `sdelete` does not allow for I/O throttling and will write out zeros in large blocks as fast as it can.

    DB:3.35:How To Do Space Reclaimation From A Thin Provisioned Lun Using Vaai Features? s9






    Hi,

    I am new to VNX. I want to know how to do space reclaimation from a FC Thinly Provisioned LUN. Basically what we did was, we moved (i.e. Storage vMotion) some Virtual Machines to a new Datastore and some were deleted from the old Datastore.

    Although, vCenter reported that space was free in the Datastores, in the storage reported that spcae is still utilized.

    In that case, How do I reclaim that Dead Space? What commands do I need to issue? Please help..

    Thanks

    DB:3.35:How To Do Space Reclaimation From A Thin Provisioned Lun Using Vaai Features? s9


    The only way to reclaim space today in a vSphere 5 environment is manually via the native ESXi tool: vmkfstools. A storage vMotion doesn't reclaim the space in the thin provisioned LUN as you have witnessed already.

    At a minimum, you will need ESXi v5.0U1 which is when it was reinstated, and since you mentioned you own a VNX, SCSI UNMAP was supported since the GA release of Franklin (VNX OE 31) so you have a supported array. Just to mention a little bit of history, until v5.0U1, it was suggested to disable it due to performance issues; in fact, v5.0 patch 2 disabled it (if you didn't already). From the array's perspective, this VAAI feature also requires that the ESXi hosts are registered with failover mode of 4 (ALUA). As noted in the following articles, I would also verify that the following "Advanced Software Setting" under the vSphere Client Configuration tab is set to 1:

    VMFS3.EnableBlockDelete

    or via CLI:

    esxcfg-advcfg -s 1 /VMFS3/EnableBlockDelete
    esxcfg-advcfg -g /VMFS3/EnableBlockDelete

    The following articles do a very good job of explaining how to verify you have a supported configuration and the steps necessary to reclaim the space:

    DB:2.98:Vcb Backup Image Size 37


    I am running a vcb script on my ESX host to backup 3 VMs. When I look at the size of the resulting VMDK files for one of my VMs on my backup proxy after the vcbMounter process dumps the backup I noticed that it is substantially larger than the space actually used in Windows. Example:

    VM A: VMDK size: 20 GB Used space in Windows: 10.7 GB Size of VMDKs on backup proxy: 11.7 GB

    VM B: VMDK size: 20 GB Used space in Windows: 4.96 GB Size of VMDKs on backup proxy: 5.64 GB

    VM C: VMDK size: 50 GB Used space in Windows: 13.4 GB Size of VMDKs on backup proxy: 45.6 GB

    Looking at these sizes it appears that the size of my VMDKs for VM A and VM B are closer in line with the actual space used in Windows as opposed to the actual allocated size of the VMDK. However, VM C is substantially larger with no apparent reason. I have verified that there are no hidden disks, etc... that would be causing this issue. The VM only knows about the one virtual disk. What is causing the backup of VM C to be so much larger? Looking at other posts on this forum someone talks about SDELETE. Is it possible that this could resolve my issue?

    I really need to get this resolved so my backup window comes back down in line.

    DB:2.93:Thin Provisioning Worse Off? k3


    Thin provisioning, which suppose to reduce storage, actually demand even more storage faster! Here's why:

    Said a VM is given 80GB and used only 10GB for now. The projection of 10GB growth per year mean that 80GB will be insufficient 8 years later. However, the daily temp file of 50GB will mean that there will be insufficient storage for the temp file just 3 years later.

    To overcome this, a 100GB SAN storage is presented as a 2TB volume to this VM so that additional storage can be purchase 3-5 years later easily. However, due to the way OS handle file deletion, 100GB will be insufficient immediately just after 2 days instead of 3 years!

    btw, how do we free up the storage after running sdelete on Windows without having access to storage vMotion? The shrink function in the vmtools does not work.

    DB:2.93:Thin Provisioning Worse Off? k3


    You must differentiate:

    If you want to free up space on the VMFS volume you need to zero-out the space in the guest to shrink the virtual disk. That is something related to VMWare.

    If you have a thin provisioned SAN volume and you need to zero-out the space there, as well, that is related to the SAN box.

    But as you see, it seem to be a general technical issue as depending on the level you look at, zeroing-out the free space seems to be a requirement.

    We use thin provisioning on the virtual disk level and it pays off. Why? In most of the cases the virtual disks tend to grow or the size doesn't change much. Disks which grow doesn't need to be shrinked, disks which do not grow, as well. If there is a case where much space needs to be released we can run it during maintenance times.

    Thereby thin provisioning gives us the benefit of moving guest more quickly with svMotion and to save space to hold more guests.

    Regarding thin provisioning on the SAN layer I do not see the benefit in our case, as I do not want any space allocated to VMware to be taken away from it, as the usage by VMware also tends to grow, not to shrink.

    Even if there are greater changes on a regular basis, like deploying many servers and decomissioning them again, which uses a lot of space shortly, you will need the space again and again. If that was only a one-time thing, you can free it up during maintenance again.

    I have a Win2k8 R2 guest on esxi 4.1 enterprise plus with thin provisioned vmdk. The customer let some log files get out of hand to the tune of about 80 GB of wasted space. I cleaned it up and then ran the sdelete utility with the -c option to zero the free space. I then live migrated to a new data store converting to thick, and back again converting to thin. The end result was only reducing the size by about 4 GB. For some reason the other 76 GB of wasted space has not been recovered. I tried with the guest on and off.

    Matt Liebowitz wrote:

    The shrink option isn't available in thin provisioned disks. One thing I have seen recently with 4.1 is that svMotion won't reclaim space on a thin provisioned disk (even after sdelete) if you are moving between datastores of the same block size. If you can, try doing the svMotion between datastores of different block sizes and see if it resizes properly.

    That was it. I deleted one of my LUNs and recreated it as a 2 MB block size instead of 1 MB like all the rest, migrated to it and now the vm dropped down to the same size as what's really in use. Thanks!

    I have a domain controller with 400gb thin disks which I zeroed out (sdelete -c) and now it looks to vmware like it's using all the space. My goal is to do a vtov conversion inside another vm using vmware converter and resize the partition slightly so it will use only do a file copy of the data which will shrink the vm in size.

    What I'm wondering about is if there are an special considerations when this is a domain controller on a virtual to virtual conversion before I do this? should I take a system state (i'm using 2003) snapshot before and do a non-authoritative restore afterwards? What is your advice in this matter.

    thanks

    DB:2.75:Virtual To Virtual Vmconverter Domain Controller m7


    I'd use one of the following two options (both options require that the VM be shut-down):

    1. vmkfstools: http://kb.vmware.com/kb/1028042

    2. Login to vCenter, shut-down the VM, right-click on it, then click on migrate and "move" it to another datastore. One of the steps in the wizard will let you change the disk format.

    Given that you're on Essentials, your options are limited. Like what was previously stated, I would not attempt a V2V conversion of a domain controller either.

    Also, make sure that regardless of which option you choose, there are no snapshots present for the VM prior to taking any action.

    After an enormous amount of Storage vMotion traffic last night working on this problem, I found a work-around which works for me!

    I don't know if it will work for you too, but it's certainly worth a try.

    Instead of vMotioning it onto another disk array/LUN/volume, vMotion it onto locally-attached disk instead.

    That reliably does the trick for me.

    So

    1. sdelete -c C:

    2. Storage vMotion to a VMFS volume on locally-attached disk, specifying Thin provisioning.

    3. Storage vMotion back to where it started.

    Matt Liebowitz and myself are trying to get to the bottom of why this appears to fix it, as he doesn't have this problem at all but I do, despite us both running 4.1 everywhere with all patches applied.

    ** Thanks in advance to anyone that contributes knowledge. Note:I am still new to PowerShell. **
    The goal ofthescript that I need help with does the following:
    - Keeps a count of the total number of files in a specific folder called Futronics Images.
    - Keeps a count of the number of filesin this folderthat are older than 1 hour.
    - Any/All files older than 1 hour ... should be deleted using sDelete. (Note: all files NOT older than 1 hour shouldn't be deleted and should stay in this directory).

    Start of Current Code:
    #Setting source folder path
    $SourceFolder = C:\Users\KDB8916\Pictures\Futronics Images

    #This code counts the total number of files in source folder (i.e., C:\Users\kdb8916\Pictures\Futronics Images) for logging purposes
    $Count1 = @(Get-ChildItem $SourceFolder).Count
    $Count1 = Total number of files in source folder = $Count1
    echo $Count1

    #The variable $Count2 reflects the total number of files older than 1 hour
    $Count2 = 0
    #If file(s) are older than 1 hour ... call sDelete bat file and securely delete file(s)
    if(Get-ChildItem $SourceFolder | Where-Object {$_.LastWriteTime -le (Get-Date).AddMinutes(-1)} | ForEach-Object {$Count2; $_.fullName})
    {
    #Calling the sDelete batch script twice for Futronics device due to it saving bitmap image in subfolder by default
    ./sDelete_Futronics_GOOD_2.bat
    ./sDelete_Futronics_GOOD.bat
    $Count2 = Total number of files in source folder older than 1 hour that have been deleted = $Count2
    echo $Count2
    }

    End of Current Code

    './sDelete_Futronics_GOOD.bat' is being called in the IF statement as you can see.
    The contents of 'sDelete_Futronics_GOOD.bat' is a simple one liner as seen below:
    sdelete -p 5 -s C:\Users\KDB8916\Pictures\Futronics Images\*

    Note: The way images are being saved in Futronics Images is in a subfolder. So when an image is taken with this Futronics device ... it creates a subfolder within the Futronics Images parent folder ... and places a Bitmap
    file in it. Futronics Images Subfolder Bitmap
    The only solution I can find in order to delete both subfolder and bitmap (that are older than 1 hour) is to call sDelete twice. Furthermore, I found that I need to end the sDelete command using '\*' as you can see above. This prevents sDelete
    from deleting the parent folder -- Futronics Images when there is no subfolder bitmap older than 1 hour to delete.

    Issue: When both of the ./sDelete_Futronics_GOOD.bat lines of code are commented outthis works as I want it to. It keeps an accurate count of the total number of files in the Futronics Images directory, as well as a count of
    the bitmap files (not subfolders and bitmap files) that are older than 1 hour ... to be deleted by sDelete.
    When I uncomment both of the ./sDelete_Futronics_GOOD.bat lines of code ... I still get accurate counts, HOWEVER, sDelete deletes all files and subfolders regardless of whether or not they are older than 1 hour.
    (Once this code works it will be run every 15 minutes as a scheduled task with elevated permissions due to usingsDelete.exe)

    Any suggestions would be greatly appreciated. Thanks.

    DB:2.67:Zeroize Unused Vmfs Blocks? fj



    We are using a disk array that supports thin provisioning and zero-block detection (3PAR T400). When the array detects that a 16KB block has been zeroized it de-allocates the block and returns it to the 'scratch' pool so another LUN can use it. We can manually zeroize blocks within a VM using the Windows sdelete command. This works perfectly, and I've done testing to prove to myself the unused blocks are returned to the array's scratch pool.

    However, I don't know of a way to zeroize unused VMFS blocks that aren't occupied by a VM. For example, if I have a 200GB VM that I storage vMotion to another LUN the 200GB of data is not zeroized on the original LUN so the array still thinks those blocks are allocated. I want to reclaim that once previously allocated 200GB of VMFS space.

    I could create an eager zeroed VMDK that was sized to use up almost all available datastore space, but that is not as automated as I'd like. I'd like a VMFS command that would just zeroize all unused VMFS blocks.

    Ultimately it would be best if VMware used the VAAI extensions to tell the array to zeroize all unused blocks when VMFS space was freed up, say by moving a VM. That way it would be completely automated and transpartent for arrays that support the VAAI extensions and zero block reclaim.

    And Dr Dedupe, TR-3505 is now downloaded and I'll have a good read - cheers for the suggestion, Our nightly snap occurs at midnight and takes between 23 and 40 seconds depending on the rate of change, the dedupe on this volume also starts at midnight and takes around 6-7 minutes (System Manager is useful!! ) so I'll change the timing of this, see what happens and report back once the snaps roll off the back of my schedule.

    DB:2.61:Vmkfstools -K For Snapshots? f1



    I have some VMs with snapshots that can't be deleted or consolidated for specific reasons. The base vmdk is thin provisioned and I have reclaimed space by running sdelete -z followed by vmkfstools -K against it, can that also be done safely on snapshots? I have one snapshot in particular that is nearly as large as the 150GB thin-provisioned size and I'm looking to optimize the VMs as much as possible.

    Example

    base = vmbase.vmdk, 150GB before, 30GB after

    snapshot1 = vmbase-000001.vmdk, 20GB before

    snapshot2 = vmbase-000002.vmdk, 17GB before

    Thanks for any help.

    DB:2.61:Vmkfstools -K For Snapshots? f1


    I'm afraid you're out of luck. As you may already have found out, running sdelete on a VM with snapshots will write the zeroes to the current snapshot .vmdk file, so that doesn't help with the base disk. Furthermore, vmkfstools -K (--punchzero) is for thin provisioned virtual disks only, not for snapshots. The difference between thin disks and snapshots is that thin provisioning uses a file system feature, and snapshots use a sparse file format, i.e. maintaining the metadata in the .vmdk file.

    DB:2.59:Thin Provisioned Vmdk Space Reclaimation - Actual Vmdk Size Vs Actual Guest Used Size xm



    Hello everyone,

    I am hoping that someone can help me with a script I am trying to use so that I can eventually try to reclaim space back from thin provisioned vmdk disks when the guest operating system is no longer using the space. I've been tweaking for a couple of days but just can't find the right bit of code.

    What I need therefore is a script that can gather the actual size of the thin provisioned vmdk file (not the provisioned size) and compare that against the used space reported by the guest OS through VMTools. For example I might have a 100GB thin provisioned disk. The VMDK file might be 80GB because at some point the OS was that full. However now the Guest OS is only using 40GB. I would like a report that shows all three figures for comparison. I can then plan a project to run sdelete on the Guest OS then svMotion to a datastore of a different blocksize and then back again to reclaim the thin provisioned space.

    At the moment I have adapted another script from the forum:

    $report = @()
    foreach ($vm in Get-Cluster IAAS_MGMT | Get-VM){
    $view = Get-View $vm
    $row = '' | select Name, Provisioned, Total, Used, VMDKs, VMDKProvisionedSize, DiskLetter, DiskUsed, Thin
    $row.Name = $vm.Name
    $row.Provisioned = [math]::round($vm.ProvisionedSpaceGB , 2)
    $row.Total = [math]::round(($view.config.hardware.Device | Measure-Object CapacityInKB -Sum).sum/1048576 , 2)
    $row.Used = [math]::round($vm.UsedSpaceGB , 2)
    $row.VMDKs = $view.config.hardware.Device.Backing.Filename | Out-String
    $row.VMDKProvisionedSize = $view.config.hardware.Device | where {$_.GetType().name -eq 'VirtualDisk'} | Sort-Object -property CapacityinKB -descending | ForEach-Object {($_.capacityinKB)/1048576} | Out-String
    $row.DiskLetter = $vm.Extensiondata.Guest.Disk | Sort-Object -property Capacity -descending | ForEach-Object {$_.DiskPath} | Out-String

    Hi all!

    I have been reading different HOW-TOs on how to shrink a thin provisioned disk, to free up storage.

    I have tried alot of the suggested approaches, but it does not work for me...

    THe set up:

    ESX 4.1 update 1

    EMC Clariion CX4-960 storage.

    VM: Win2008

    40GB c-disk

    600GB d-disk.

    c-disk uses 30GB and I do not need to shrink this one.

    d-disk used about 250GB but after a huge cleanup now only uses 25GB.

    I downloaded sDelete v1.6 and since they have done some changes between 1.5 and 1.6 (changed -c to clean and -z to zero - in 1.5 it was the otherway around) I did a sdelete.exe -c d: which did not work.

    I then did a sdelete.exe -c d:\ which started and went all the way through.

    It stated as far as I rembember "Zeroing free space" but according to sdelete.exe -? the "-c" should do a cleaning not a zeroing.

    Disk grew to 600GB as I was expecting.

    I then took a svmotion to another LUN - and the disk was still 600GB

    So i did another run with sdelete -z d:\

    It completed without any errors.

    sVmotion'ed it to another LUN, but disk is still 600GB

    It there ANYTHING I am doing wrong, or is there an issue with this on 4.1u1

    Thanks in advance

    Thanks for all the response....

    After finetuning my communitythread searches, and following jfields suggestions in this thread http://communities.vmware.com/message/1699887 it finally worked.

    The solution to this one is remarkably simple once you know it.

    It took me 2 solid evenings of Storage vMotion traffic to find the key.

    You must copy the VM between 2 datastores with a **different block size**.

    Then it works fine, assuming you've done an "sdelete -c C:" first.

    If all your datastores have the same block size, you'll have to reformat one of them to a different block size to solve this.

    if x's class is in {real, integer} then

    DB:2.56:Space Reclamation Questions. cx


    The only documented way of reclaiming free space (space showing as allocated/in use after a VM has been deleted/removed) from a thin LUN is manually running VMware commands from an ssh session ("vmkfstool -y" or in 5.5 "esxcli storage vmfs unmap"). Could thin space reclamation at a minimum be an alert in XtremIO (perhaps displaying percentage of reclaimable space on a LUN) and possibly be automated in the future?
    What's the process for reclaiming free/dead space within a VM? In the past with the CX4 this was a convoluted process of zeroing free space within a VM (Windows "Sdelete -c" or Linux "cat /dev/zero"); and storage vmotioning the VM to a VMFS3 datastore with a different blocksize (due to issues with the datamover that moves VM between VMFS5 datastores not reclaiming free space). With the XtremIO using VAAI, it makes the reclaiming of free VM space more difficult, and I haven't been able to reclaim VM free space with it yet.

    The volume size is 1 TB and there is only one LUN of 900 GB in this volume. And the datastore use all 900 GB of this LUN.

    In this datastore, I have 77.57 GB of free space in VmWare view but if I check volume free space in NetApp System Manager, I have 418,36 GB of free.

    Deduplication saved 265,67 GB (30 %) on the volume.

    There is no snapshot.

    Why is Vmware not showing all the free space ?

    VmWare NetApp plugin :

    Here, it is strange that Datastore Usage is not equal to Lun usage.

    NetApp System Manager :

    I don't think that it is a space reclaimation issue because NetApp is showing more freee space.

    I agree with the defrag and then sdelete...if you do it in the reverse order what happens is you may have data stuck out at the end and middle of your drive and then write zero's all around it...

    wherweas a defrag will consolidate all the data at the beginning of the drive and then you are writing zero's to the end of the drive....

    Similar to if you shunk a drive in windows 2008...you need to defrag to get the contigous blocks together and put your empty space at the end....

    oggi un collega mi ha posto una domanda "classica": "sulla VM X c' un disco da 260 gb, che in passato era usato quasi tutto e in futuro sar molto pi vuoto: si puo' liberare lo spazio?"

    Allora sono andato a ristudiare la questione e ho trovato un paio di link utili

    http://vinfrastructure.it/2011/12/reclaim-free-space-in-thin-provisioned-vmdk-disk/

    http://www.thelowercasew.com/reclaiming-disk-space-with-storage-vmotion-and-thin-provisioning

    entrambi suggeriscono un metodo un po' laborioso bastato su sVmotion fra due datastore con diverso block size. La cosa mi chiara, mente l'ultima riga del post nel blog di Andrea che dice

    " E quindi se soluzioni vi sono? Personalmente vedo solo questi possibili workaround:

    1)...

    2)...

    3)...4) Usare datastore NFS anzich quelli a blocchi basati su VMFS."

    e non capisco bene perch usando datastore nfs il problema non ci sarebbe. Forse si intende che facendo una sVmotion fra due datastore NFS o fra un VMFS e un NFS il vmdk verrebbe ottimizzato come fra due VMFS dal block size diverso?

    Comunque mi venuta nel frattempo una riflessione: lanciando nel sistema guest della vm "dimagrita" il tool sdelete con l'opzione "zero free space" (occhio che mi sa che fra diverse versioni di sdelete sia cambiata l'opzione per ottenerlo) si ottiene un vmdk ancora grande ma con i blocchi non utilizzati tutti identici. A quel punto, se il datastore su uno storage nfs con deduplica, lo spazio viene recuperato "indirettamente".

    DB:2.45:Recupero Spazio Non Usato In Dischi Thin km


    Su NFS potrebbero anche essere thick, se hai il VAAI per il NAS. Controlla quindi che tipo di dischi ti trovi.

    Il trucco dello sVmotion non che mi funzioni sempre. Se hai il VAAI non si riesce e una soluzione banale di spostarlo su un datastore VMFS3 (o convertito da VMFS3 con block size diverso).

I was using a technique I've seen listed in lots of different places, involving running sdelete to zero out the empty space, then doing storage vmotion to migrate to a LUN with a different block size. This has worked for at least the last couple of years.

    I'm trying it again today, and it's not working. When I do the storage vmotion, no space is reclaimed. I've triple-verified that I'm moving to LUNs with different block sizes. Just for testing purposes I've tried both the -z and -c option in sdelete. (My notes say -c is the way to go, but there's conflicting info out there, and the commands themselves seem to be flipped in sdelete documentation.)

    The only thing that's changed is we've upgraded from version 4 to version 5 of vSphere. From what I can see, people claim it still works in v5, but that's all I've got to go on. Anybody else experiencing this.

    DB:2.45:Reclaiming Space On Thin Provisioned Disks - Used To Work, Doesn't Now 99


    I'll have to check with the other admin, as he did that work. I hope that's not it, because recreating and migrating 30 TB of data on new LUNs doesn't sound like much fun.

    I'm struggling to make sense of that first article. It's got a lot of commands and technical terms I'm not familiar with, and doesn't explain things very well. (Or I need more coffee, maybe.) I don't understand at all why I'd be inputting a percentage of blocks to reclaim, or why that would ever be less than 100%? I also tend to draw the line at any VMware maintenance that requires the command line rather than the GUI as being more technical and more risky than I'm prepared to deal with.

    DB:2.44:Cant Get Rid Of Volume Read Only Attribute 7s


    We have a piece of software which scans available mounted drives on the machine in order to list them for use as a backup tarrget.
    The problem is sometimes we have drives not being detected and therefore dont show up in that list.
    I ran a procmon when the disks are being scanned and our tool does a 'QueryOpen'
    call on alldisks but the one not being detected has 'FileAttributes'
    = RHSD, all the others have HSD. Assuming that 'R' is for read only, this apear to be our problem.
    Running DiskPart shows the volume is not listed as read only

    We tried to create a new partition on this drive, and it works as expected: the drive has HSD properties and is populated within the list

    DB:2.43:Questions About Lun Space Reclaimation m7



    Greetings!

    I have a few questions for you guys. I have been studying how the reclamation of deleted blocks occurs on a given datastore. While I get the commands to do this ("vmkfstools -y" in 5.0/5.1 and "esxcli storage vmfs unmap" in 5.5), I need clarification on what is actually happening.

    1. If the datastore is 600GB and shows 100GB free in vSphere, is the full 600GB shown as allocated on the SAN?

    2. We are running vSphere 5.1. If I run "vmkfstools -y 50" to reclaim 50% of free space, what happens to the SAN?

    3. Does the reclamation only affect deleted blocks, or does it affect all free space?

    That's all I can think of for now. Thanks!

    DB:2.40:.Vmdk File Now Larger By 50% After Running Sdelete kx



    Hello,

    We have 2 Virtual machines running VMWare Server 1.04, these run as W2K3 guests, the physical host that they reside on has run out of local disk space, so, I have copied one of the VM's off to another server so that we could try shrinking the VM's.

    On one of the VM's this is what happened, it didn't happen on the other VM when we did the same steps

    1. The .vmdk file is set to have a maximum size of 65gb,current size of the .vmdk was approx. 35gb, the guest has 2 NTFS partitions (C: D:) that are approx. 35gb in used space.

    2. From within the W2K3 guest, we deleted any redundant log files etc, and then defrag'd both the partitions.

    3. I then ran sdelete -c c:, followed by sdelete -c d:, followed by sdelete -z c: and then finally sdelete -z d:

    4. Once the VM had been closed I noticed that the size was of the .vmdk file was now 57gb!!!!, even though from within the w2k3 guest the used space within partition are the same size(s) as before. #1.

    5. I have also run vmware-vdiskmanager -d and also vmware-vdiskmanager -p , followed by vmware-vdiskmanager -k to shrink the file but to no joy.

    Does anyone now why the file size of the vmdk has increased, and more importantly how I can get it back to 35gb size in order for me to copy it back to it's proper host.

    Many thanks

    Jon

    I managed to resolve this, by re-running the vmware-vdiskmanager -p and vmware-vdiskmanager -k again, on running with -p this time around it took a lot longer to prepare the file, after re-running -k the file returned back to it's 35GB size.

    Здравствуйте, меня зовут Тигран.

    Ситуация такая.

    Есть система, Windows Server 2008 R@2SP1 с thin provisioned диском. На ней были темповые файлы, которые я удалил, в системе показывается, что занято всего 25 гига, а вмвер говорит, что занято 35. Делал следующее.

    1.после удаления сделал дефраг.
    2.использовал утилиту sdelete.
    3.с помощью vCenter standalone converter -а сделал конвертацию и поставил опцию диска на thin.

    После конвертации система все равно жрет уже 50 гигов(после sdelete)...
    Как я понял по комментариям, выше описанная процедура для 5.0 сферы работает на ура...

    Что можно сделать для того, чтобы получить обратно 25 занятого пространства на датасторе?

    Заранее спасибо!

    Проблема решена!!
    sdelete -z надо было делать а не sdelete -c ...

    DB:2.39:Vsphere 5.1 Shrink Thin Provisioned Vmdk Disk 3j


    Запустить внутри виртуалки sdelete.exe чтоб обнулить пустое пространство (если это винда)

    или dd bs=1024k if=/dev/zero of=/fuflo ; rm /fuflo (если это linux)

    Затем сделать две миграции диска (storage-vmotion или по холодному)

    1. из тонкого диска в thick eager zero

    2. из thick eager zero - в тонкий.

    если виртуалка выключена, первую миграцию можно не делать, а превратить диск в thick eager zero на месте с помощью Datastore Browse -- Inflate

    При перегоне диска из thick eager в тонкий обнуленные блоки изымаются гарантированно и танцы с бубном по использованию разноблочных VMFS и/или отключению оптимизирующих датамуверов не требуются.

    Hello;
    I am having problems with VB6 and SQL Server 2005 and 2008. I am working with an application, built by a vendor but I have put a lot of work into myself. It is an archive and retrieve app that deletes records from the prod db and inserts the same rows into
    the archive db. In most cases, the app does what it is supposed to. Every now and then, a little too often for my liking, I get an ODBC Timeout error ([Microsoft][ODBC SQL Server Driver]Query timeout expired).
    I have tried to increase the timeout (*.sCommand.CommandTimeout = 120 and even 0) to no avail and I have changed the provider from msdasql tosqloledb. I have narrowed the error to a moveNext on a recordSet but the error I get states that it is a timeout.

    Do While rsNames.EOF = False

    I guess I'm looking for a definitive answer on this. Upon taking a new job, there's a branch office that has an ESXi 5.1 server. On it there is datastore1 and datastore2. Datastore1 was created before we were in the picture, and for some reason the person that created it provisioned the vmdk to be the size of the datastore itself. Needless to say the datastore has filled up in the past, crashing the VM. I've been able to partially use SDelete and vmkfstools, but since SDelete fills out the vmdk, it fails eventually, but running vmkfstools allows me to recover some of the space. At one point I had created 50GB of free space, but another issue that's occurring, is the vmdk will continue to grow even the client OS, Server 2003 R2 has 160GB of free space. So I guess I have two questions, one why is the vmdk growing when it doesn't need to? Second, what are my options to shrink this vmdk? For a little more background, this is just a stand alone ESXi host with vSphere Client.

    Hi Sammy,

    Thin recalimation is a feature which needs to be supported by the host as well as the SAN.

    In order to achieve reclaimation the SAN vendor will give a plugin that needs to be installed on your host and also you might have to install appropriate plugins for the host as well.

    vSphere 5 supports thin reclaimation with the introduction for VAAI version 2, as per VNXe we support VAAI for NFS.

    DB:2.25:Zero Only Previously Deleted File Space? f8


    Good Morning All,

    I'm hoping somone can help me with a special set of circumstances I have.

    I have the requirement to export RHEL5 Linux VMs as Virtual Appliances periodically as a contract deliverable for my customer.

    These VMs are running in ESXi and the VMDKs are on a NetApp device as NFS mounts from ESXi. The VMDKs are initially thin provisioned.

    When we export, we have found that zeroing all unused disk space first can significantly reduce the size of the resulting VA. We are a development shop with lots of changes happening to the VM between VA exports. Zeroing deleted file space prevents the VA process from exporting those blocks.

    The problem: If we start with thin provisioned VMDKs, and then zero the the unused space on the partitions using the popular method of creating a big file full of zeros, then deleting it, we are essentially no longer thing provisioned. Creating the zero file writes to the entire virtual drive, which causes ESXi to allocate file space the the VMDK. Our 8GB thin provisioned VMDKs become 50GB VMDKs which means I have to allow for this greater size in my NetApp volume allocation. Remember, I am in a development shop. I do not need the speed associated with flat VMDKs. I need available storage space to allow for rapid and temporary provisioning of new VMs. If I can prevent this growth, I have more storage space available for other stuff. No, I can't use Dedup/ASIS on the NetApp. It is a 270c and Dedup/ASIS is not supported.

    What I'm looking for us a Linux utility that will zero only the blocks that were previously used for files. It appears that a utility exists for this in the Windows world, SDelete by Mark Russinovich, but I haven't found a similar tool in the Linux world.

    If I understand correctly, this type of tool will help me reduce the size of the VAs by turning deleted file space into zeros, which the VA export process will then not export, and will keep the VMDK thin provisioned by only writing to parts of the VMDK that have been written to before.

    I welcome all suggestions.

    Thanks for your time!

    DB:2.25:Zero Only Previously Deleted File Space? f8


    Although I still haven't found the tool I'm looking for, I will look into vmkfstools and take a hard look at rescheduling my NetApp snapshots.

    DB:2.25:Transparent Data Encryption (Tde) xd



    Dear all,

    My client has asked me to implement transparent data encryption on an Oracle database. After reading note 974876, I went ahead and implemented it all and I have to say it was pretty easy to do and didn't take much time.

    While I was validating the encryption results, I realised that the old versions of the encrypted data was still visible on datafile level. So, while there is an encrypted version of the data in the datafile, which is the one that is visible using se16 or select queries on database level, there is another version as well, which is the unencrypted version. I could see this data using blockdump. After looking at google, I found the below link that describes exactly what I am experiencing

    http://www.pythian.com/blogs/510/oracle-10g-transparent-encryption-not-so-encrypted

    and in fact, similar finding are in the Oracle website: The solution they propose there is the following

    -

    Create a new table space in a new data file (CREATE TABLESPACE ... )

    Encrypt the clear text values in the original table space and data file

    (ALTER TABLE ... ENCRYPT)

    Repeat 2.) for all tables that contain encrypted columns

    Move all tables from the original table space into the new data file

    (ALTER TABLE ....MOVE... )

    Drop the original table space (DROP TABLESPACE). Do not use the 'and

    datafiles' parameter; Oracle recommends to use stronger methods for OS - level operations; see 6.)

    Use tools like 'shred', 'eraser', 'SDelete' or other commands for your

    platform to delete the old data file on the OS level.

    -

    Any ideas what you should do in this case in a SAP environment. I was thinking of following the instructions above, which is really a tablespace reorganization but I would be interested in other opinions as well.

    I opened a message to SAP about this but came back to me saying that this is a consulting issue. Nevertheless, I believe that this should have been covered in note 974876, since this note claims to give you instructions on how to configure encryption and then you end up with having datafiles on disks (and in tapes going offsite) containing encrypted and unencrypted versions of the same data.

    Many thanks

    Andreas

    DB:2.24:Powercli Script To Report "Used Blocks" On Vms s9



    Does anyone know if there is a way to report on "Used Blocks" as opposed to calculating space used (provisioned space - free space)? We have a backup vendor (Commvault) that is proposing capacity-based licensing, but they are showing vastly different numbers of space in use (sometimes up to 30GB per VM higher) compared with our readings of actual space in use by the Guest OS. They claim their results are based on the VADP API for "Used Blocks", and it appears that this number is a "high watermark" for the amount of blocks that were ever used by the guest OS.

    As an example, say we have a Windows VM guest that is reporting 50GB of data requiring backup protection. We can supposedly run the SDelete utility on this guest and it would show 30GB needing protection. Their formula is:

    Prior to running SDelete.exe:

    Backup Capacity needed = Guest Host Size + Previously Used Blocks + VMOverhead

    After running SDelete.exe:

    Backup Capacity needed = Guest Host Size + VMOverhead.

    We are unable to run SDelete on many of our guests, so what we'd like to do is to run a script to report the same numbers that Commvault is reading from the VADP API. I'm hoping these numbers are exposed via PowerCLI, but as yet I've found a way to read them.

    Any ideas appreciated!

    DB:2.24:Reclaiming Space On 3par 39



    Hello,

    I've been searching through this forum since there's barely any information out there on the net and 3par support doesn't seem to be of much help.

    I have a TPVV (thin provisioned virtual volume) of 1 TB for some VM's.. We recently got a notification indicating it was nearing capacity. I went through most of the VM's (mostly Windows), ran Sdelete, converted any that were configured with thick-volumes into thin. I did this by moving to local storage and then back to the TPVV. According to vSphere, the amount of used space is under 60%, yet the 3Par is still claiming to be near capacity.

    When I went to the 3Par CLI, I ran the command:

    compactcpg -dr [CPGNAME]

    The CPG is basically the virtual volume. We allocated 1 TB to the CPG and created one TPVV of 1TB. The dry run indicates that the SA and SD disks would not reclaim any space. In looking at the logical disks, I see that most of them have the space taken up.

    I've gone through the documents, the net (basically this forum) and 3par support, but I haven't found my answer yet. Hoping one of you experts know!

    If you're running InForm OS 2.3.1, you may need to check if the "Copy Space Reclaim" option is enabled under the system properties. I ran into this after upgrading to 2.3.1 MU1. Apparently, it changed the Copy Space Reclaim setting to disabled. This has been fixed in subsequent builds and is enabled by default in 3.1.x.

    I have a Windows XP guest on Fusion 3.1.0 and the VM files seemed too big so I've been trying to shrink them. The problem is that the vmdk does not shrink.

    I've deleted all snapshots (and manually got rid of some "orphaned" vmem and vmsn files that were left over).

    In Windows the C: shows as ~15GB used / ~25GB free / ~40GB total. In Finder the vmdk is ~43GB (presumably the 43 is because Snow Leopard is 1000^3 based).

    I've tried shrinking from within the guest/VMware Tools a few times - doesn't significantly alter the vmdk size, still ~43GB. Also tried Cleanup disk option from the host/VM settings disk options - doesn't help. The virtual disk is not (and has never been pre-allocated). It was split in to 2GB chunks, but I've also tried consolidating to one big file - doesn't help. I've tried zero-ing free space (using Sysinternals sdelete /z) - doesn't help.

    How can I get back my 25GB?

    No snapdrive for Windows was purchaed.

    The Luns Reservation set to zero
    Volume Fractional Reservation set to zero
    Snap Reserve are set to zero or disabled.
    Volume is Guaranteed, Autosize, and AutoGrowth are enabled.

    The statemt is, if one lun per volume is guarantee (guarantee=volme) and the volume has unallocated space, that “free space, ” is used for the lun as it is modified and the old blocks are held in the snapshots. But I set the snap reserve to zero. I did not set the guarantee to “none” (thin provision the volume), because the “free space” will be used by other volumes on the aggr in question and the thin provisioning needs to be monitored carefully as to not run out of space on the VMFS datastore. That would be a bad thing.

    The question: If these statements are true, can someone tell and/or show me how to use the reclaimation cli via ssh to reclaim the VMWare (Datastore) lun per voluem free space?

    Michael -

    I'm not sure what it is that SnapDrive is doing under the hood when you do a space reclaim, but you may want to try running reallocate on the LUNs in question to reclaim freed space within the volume.

    (I'm going to try this out in my lab environment...)

    BTW Snapdrive isn't that expensive - it's well worth it in SAN implementations.

    I hope this response has been helpful to you.

    All,

    Here's a quick rundown on my environment:

    3 ESXi Servers running ESXi 4.1All hosts are attached to:EMC AX4-5 FC SAN (SAS)EqualLogic iSCSI SAN (SATA)Using the VMware agent on Symantec Backup Exec 2010 R2 to backup the VM's

    I'd noticed that the backups of one of my VM's was a lot larger than the actual data that was on the disk. In investigating, I also found that while thin provisioned, the disk was also showing that the "used storage" for this VM was almost the same as the provisioned storage. I did some hunting around and I found basically the following 3 statements in a lot of the stuff I'd seen:

    Run sdelete -c drive on each disk to 0 out the space that had been occupied by files that have since been deleted.Use Storage VMotion to migrate the disk from one LUN to the other.Make sure that the block size on the source and target LUN are different, or storage VMotion will not reclaim the zeroed out space.

    Well, I've taken the time to do this. And now my symantec backups have shrunk as expected. Inside windows I show ~27.92 GB of data, the Symantec backup now shows it backed up ~28.10GB of data (transport mode nbd). But, in VMware I still show 154.01 GB of provisioned storage, with 153.92 GB of used storage on this virtual machine. This is after several iterations of moving it between a 2TB LUN with a 4MB block size on the EQL SAN and a 1.07 TB LUN with a 2MB block size on the EMC SAN with storage VMotion.

    Is there possibly something I'm missing (or misunderstanding).. or maybe something has changed since the articles I was reading were written (around Jan/Feb of 2011). I somewhat expected the used storage to drop back down to around 28GB or so after doing this.

    Thanks,

    Clif Godfrey

    DB:2.20:Svmotion, Thin Provisioning, And Reclaiming Space 1c

    Thanks.

    for the majority of SAN you can't reclaim space.. Especially from a LUN. You still can't reclaim space from a VMFS datastore..

    And it's not a complete "unmap"

    http://www.yellow-bricks.com/2011/07/15/vsphere-5-0-unmap-vaai-feature/

    Now one thing I need to point out that this is about unmapping blocks associated to a VMFS volume, if you delete files within a VMDK those blocks will not be unmapped!

    All the decent ones can Hitachi, 3PAR, EMC can all do this

    Correct - doing a straight 'rm' wont cause it to happen, but doing regular events (like a API delete or a svmotion) WILL cause the UNMAP code to run.

    We are migrating VM's from a 3.5 ESX server to ESXi 4.1.

    The systems range from W2k server to 2008R2 and during migration (cold migration), we convert the disks to thin provisioning.

    All systems converted correctly with the exception of one XP SP3 VM - single 25GB VMDK which remains at full size/allocation.

    The process used:

    Delete all temporary files, delete the disk swap file, defrag with PerfectDisk set for contig free space and the boot option to optimize the MFT, run sdelete -c and then migrate. I have also tried using the VMTools option 'Shrink' option just prior to migration. I have repeated the process 3 times (going back to thick, re-running everything and migrating to another datastore) all with the same results.

    Even though the system has less than 10GB used, and PerfectDisk shows contiguous freespace, the resulting VMDK is full size (25GB).

    This process has worked for other systems, including XP.

    Any suggestions on what else I might try?

    DB:2.19:One Vm That Will Not Convert To Thin 9a


    Using converter worked - I wasn't aware it provided the option to not only resize the VMDK down, but to also move out the swap file.

    Hi Everyone,

    I have a question regarding white space reclamation beause of thin provisioned disk.

    If I delete data, the free space is not reclaimed from datastore.

    In order to reclaim the free space, I tired out following:

    1) On windows machine, If I have to reclaim free space form h drive I used sdelete -z h:

    then performed storage vmotion keeping disk format same as it was already thin provisioned disk.

    But It did not helped. There was no change on datastore.

    2) I then tried VAAI vmkfstools

    vmkfstools --punchzero VVM1.vmdk at datastore path where this disk reside. If reclaimed space but only when VM was shutdown. It was not able to read file if VM is power on.

    3) I also got vmkfstools -y percentage of space to be reclaimed from datastore but as here this percentage is to be guessed and risky I am of little interest to run.

    So is there any way I can reclaim disk space without turning off the VM.

    b) is the VTL tape space provided thin/thick ? if VTL space is reserved in someway, will deleting of certain tapes help. as of now my DD box has 2000 tapes configured , if a cut it down to 1500 will that help ?

    c) My DD box is also used as directory based replication from Prod to DR dd of the NFS given, does this anyway affect the space too ?

    d) some quick fixes or immediate solution to rsolve the space crunch.

    DB:2.19:Swap Space 3d


    Hi,

    Why swap space needed for oracle while db is running?
    What circumstancce oracle use swap space?

    Thanks Regards,
    VN

    DB:2.19:Swap Space 3d

    it is not a rule, it was just because mostly systems had less physical memory earlier so we had to made swap space just double of ram but now days system have sufficient physical memory around 1 GB or more then 1 GB mostly ,so there is no need to create 2 GB swap partition if you do create only 1 GB swap your system will work fairly without any issue.
    for example, if your oracle database has 6G RAM allocated in the SGA, it will allocate both 6G RAM and 6G swap. If there is insufficient swap space, it wont kill other processes to make space. It will lock up the program attempting to allocate space, and eventually any other processes on the system that need swap space will also hang.
    Oracle recommendation is if you have between 1 and 2G RAM, you need to configure 1.5x RAM for swap space. For 2 to 8G RAM, swap space has to equal RAM. For RAM more than 8G, swap needs to be RAM.
    Despite what the official Oracle documentation says, the recommendation is that the minimum swap space should be equal to the available RAM, and 2x swap to RAM is the maximum amount that should be needed.

    I have a copy of the command prompt on my flash drive because I like to use sdelete to delete my files when I am working on public computers. Maybe I am just paranoid, but I don't want people stealing my files. Anyway, it's worked out well, but recently

    ...however, their solution did not solve my problem. I am really just wondering if this error is normal, what it means, and how it can be resolved. I appreciate any help I can get; it doesn't seem to be a serious problem - I just am curious and would like
    to learn more about it. Thanks!

    DB:2.18:Space Reclaimation On Nfs Export For Vmware Datastore af



    Hello, I apologize in advanced if this is an obvious question, but we are just getting started with NetApp.

    We are testing NetApp to work with our VMware infrastructure. Currently we have connected a NFS export to a ESXi 4.1 host.

    We moved a VM from a VMFS datastore to the NFS datastore and it seemed to go just fine. The VM was just a 40 GB C: (40 GB .vmdk, thick lazy zeroed) and when we moved it to the NFS datastore it automatically changed it to a thin provisioned VMDK. Both VMware and the NetApp were only showing 14 GB used on the datastore since most of the 40 GB is free space. We then ran a de-dupe job on the NetApp and it went down to 11 GB. Sweet!

    Next we added about 15 GB of data to the VM and noticed both VMware and the NetApp said the datastore had 26 GB of data (11 GB existing + 15 GB new).

    But after we deleted the 15 GB of data in the VM the space did not appear to be reclaimed. Both the VMware and NetApp sides show that 26 GB is still in use.

    We tried to run a de-dupe job again, but that did not seem to reclaim the space.

    So, my question, is there a process to free up space on the datastore after you delete the data in the VM hosted on that datastore?

    It seems the thin provisioning is a one-way street...

    Hi everyone,

    Been reading over a lot of the documentation and trying to familiarise as much as i can with ESXi 4.1 and seem to have got myself in to a muddle

    If anyone could help me understand it a bit better it would be much appreciated. Sorry if i am being a dummy too!

    When you create a new VM you have the option to place the swapfile in the same location. This swapfile is used to swap out memory pages by the guest OS when the VM is experience high memory utilisation. Is this correct?When ESX is doing hypervisor swapping memory reclaimation does it use the above mentioned swapfile or does it create a seperate instance locally per VM?What is userworld swap and should it be enabled? Saw this option when was looking into the scratch partion on my ESXi hosts. What is it used for?Where is the host ESX swapfile and what is it used for?

    Really hope someone can explain this all!

    Thanks for all your support guys

    Is there a good reliable way with no down time to shrink a thin provisioned VMDK? i've tried using sdelete and svmotion off to a datastore with a different block size but the VMDK is still not shrinking. Any help will be appreciated. Thanks.

    DB:2.18:Shrinking Vmdk In 5.0 ka


    VMware convertor can do this- but you need a downtime to swap the servers.

    Shrinking with VMDK wont reduce the size of the vmdk, but it will zeroout the disk.

    Attach a new disk, with required size and copy the data from the old to new disk. Remove the old disk, if this is not used by any applicaiton and it has onlys on it.

    DB:2.18:Disk Management Breaks My Vm 9k


    I am using WS9 in 64bit Linux (Fedora 17.) I recently used "sdelete -c" in my Win7 guest to prepare for virtual disk compression, but it filled the partition and crashed the VM. That crash created a Win7-000001.vmdk disk file that I cannot get rid of. If I clone the VM, the new VM crashes with a BSOD 8e error. If I use vmware-vdiskmanager to convert the sparse disk to a flat disk, the new VM crashes with a BSOD c000021a error.

    Note that the existing Win7-000001.vmdk / Win7.vmdk combination works - I just want to get rid of the 000001.vmdk file.

    Lastly, the Win7-000001.vmdk file appears to be an AutoProtect snapshot that was created during the first crash. The Snapshot Manager does not show any snapshots.

    So, how do I get rid of the Win7-000001.vmdk file?

    I recently upgraded from WS7 to WS9, and I am still in the 30-day support period, but the website will not let me create a support ticket. Hence, I am describing my problem here.

    DB:2.18:Virtual Provisioning Behavior With Vmware ap



    Hi,

    I'm starting to test VP LUNs presented to ESX 3.5 .

    Here is the scenario:

    - One VM(win 2003) of 265GB with 75GB of free space inside the VM.

    - One Thin pool with a thin device of 500GB.

    We have storagevmotionned the VM to this new thin device. Usage in the pool was 270GB. I ran a space reclaimation and the usage went down to 250GB. I was expecting it to go down around 200GB.

    From readings I've found that the zeroedthick format is the VP friendly one and I was expecting that since the blocks are not initialized my real usage in the thin pool would have been 200GB.

    Do you gus know how it's supposed to behave ? Could it be related to the version of ESX ?

    DB:2.16:Free White Space Esxi 5.1 1p



    Good morning,

    I recently upgraded to version 5.1 in the hopes of being able to clear white space. This does not seem possible.... My SAN System doesn't suppor the ability to UNMAP. From what I've read I should be able to Vmotion the machine and reclaim the dead space but I have yet to have it work.

    I have tried both sdelete -c and -z, then vmotioned each with no sucess. What am I missing? Should I try thin to thick and back to thin again? Should i just create a new SE disk and move the data to this disk?

    Any help would be appreciated,

    DB:2.16:Space Reclamation Of Thin Provisioned Disk Won't Work a3



    I want to reclaim lost space from a thin provitioned disk of one of my vms. First I coppied 30 gb of data to my 100 gb thin provisioned disk and deleted it again. After that the 30 gb are still occupied/provisioned. So far so good. Then I installed sdelete and wrote zeroes to all of the blocsk of this disk (100gb).

    Am I right that at this point it's not possible just to use the umap-vaai feature "vmkfstools -y xy" (were xy is the % of reclaimable space)?

    So what I'm suppose to do is to perform a storage vMotion, right? So I did a svmotion to my 2nd iscsi-lun und the result is now a 100gb provisioned disk.

    Where am I wrong and when do you guys use the umap-primitives?

    Hi

    In our esx 4.1 enviroment I have trouble to reclaim space from some virtual servers.

    I have tried with storage vmotion

    I have tried using sdelete -c and then after storage vmotion.

    I have also tried swithing to thick and then thin provisioned, without any luck.

    I have tried the storage vmotion when the machines are turned off.

    But my servers do not release the unused space.

    Any idead what I could do?

    The simplest method is to use VMware standalone converter. You have an option to change disk size. It doesn't matter up or down in size. When you change size Converter creates a new blank disk and does a file copy to the new disk. No complicated command line and the operation is relatively quick. You can have Converter run against a running VM, shut down services on the Old, quiesce and sync the changes to the new VM, shut down the old and start the new.

    DB:2.15:Symmetrix Management Console Administration Guide ac


    Boom has a good suggestion with the Procedure Generator, but that will just tell you how... not what, when , and why.

    If I understand your question correctly, I suspect you are looking for something that is going to be significantly more than what you will find in any one document. The Admin Guide for SMC will tell you how to do what you need to using SMC as the tool to get there, but is still won't tell you what to do, when to do, or why.

    If you are trying to get an overall understanding of the Symm technology you are managing, you should be looking at some formal training. If that isn't possible, the best advice I can give you is to start digging into the SYMCLI Product Guide manuals. I learned more about the Symm tech from those than I did anywhere else. Once you understand the base level technology and processes you can build up to learning how to do things using the GUI (SMC or ControlCenter).

    DB:2.15:Thin Provisioning Not Reducing Backup Sizes c7



    I am using ghettoVCB to back up some of my VMs. I changed some of these VMs to use thin provisioning in an attempt to reduce backup sizes. When I browse my datastore using vSphere Client, I can see that the thin provisioned disks are taking up less space. However, when I back up to an NFS store on a Windows Server 2008 R2 system, the backup sizes are the same as they were when I used thick provisioning. Is this to be expected on a Windows NFS share? I did specify thin provisioning for ghettoVCB.

    I ran sdelete and the VMWare Converter to try to shrink the disks; this did decrease disk size I see in the datastore browser but the backup size on the NFS share was still the same.

    DB:2.15:Thin Provisioning Not Reducing Backup Sizes c7


    It sounds to me like Windows Storage Server 2008 deduplication won't be of much help in my situation. The Windows Storage Server uses the Single Instance Storage feature to save space taken up by duplicate files. My backups, which contain large disk image files, won't contain duplicate files.

    Am I missing something?

    Buona notte.
    Ho un dubbio: Hyper-V su Windows server 2012 (no R2). Backup con HP Data Protector Express (operante mediante
    VSS). Domanda: è necessario passare lo spazio vuoto con SDELETE per azzerarne il contenuto al fine di ridurre lo spazio occupato nei backup?
    Grazie in anticipo.
    Ps: nel caso di necessità di azzeramento dello spazio vuoto mi potete consigliare qualcosa di più rapido di SDELETE? Lo eseguirei una volta al mese o anche meno ma ho un problema: ho alcuni VHD su un volume connesso all'HOST mediante ISCSI e le prestazioni
    di SDELETE non sembrano stabili: monitorando il traffico di rete, senza che ci siano processi concorrenti, ci sono momenti in cui la velocità è sostenuta (attorno ai 4-500Mbits) e altri lunghi momenti in cui la velocità cala drasticamente (attorno ai 20-30Mbits).
    Rischio di metterci due giorni ad azzerare lo spazio vuoto. Da cosa può dipendere? Solo SDELETE ha questo comportamento. Il Backup di quei VHD procede a velocità costante e ben più sostenuta rispetto a quella mostrata da SDELETE.

    DB:2.15:Backup Di Vhd - Necessario Pulire Con Sdelete? Hyper-V Ruolo Di Server 2012 (Non R2) 8x


    Mi pare che l'uso di VHD o VHDX dinamici non sia consigliato da Microsoft in ambiente di produzione.

    Si, sicuramente non è consigliato per un fatto di prestazioni e perché, per come sono strutturati, sono più vulnerabili a corruzioni in caso di errori. In ogni caso non è che è proprio vietato il loro utilizzo in produzione, ma ti capisco se preferisci non
    adottare questo sistema, lo farei anch'io(ti avevo elencato solo tutte le possibili soluzioni alla tua problematica).

    Hi, I have a couple of questions around memory reclaimation that I'm hoping someone can help with.

    I think I understand the 4 memory states

    high - no memory reclaimation

    soft - ballooning as host approaches soft threshold

    hard - as above, plus swap, compression (only happens on swapped pages?) ...(does break down of large memory pages into small , as so also TPS, happen here as well?)

    low - as above, no further memory allocation to vms

    I've seen hosts with high memory state, but with growing balloon and swap values (ie MCTLSZ growing towards higher MCTLTGT value and SWCUR growing towards higher SWTGT value), with no memory limits on the VMS. Anyone any ideas why this would happen?

    I've also seen the following...

    If I power on a VM on a host with no other VMs on it (VM has 3Gb memory, host has 146Gb), when the VM starts, it has 2Gb of shared memory.

    To me this suggests that the host has had a shortage of memory in the past and has broken large memory pages into smaller ones, and run the TPS algorithm to create the hash table. When the VM is powered on, it's allocated small memory pages which are compared against and found in the hash table , therefore the pages are marked as shared ?

    Does this mean that once a host has gotten to the stage where it's large memory pages are broken into smaller ones, they stay small until the host is restarted ? Is way to change them back to large memory pages ?

    Thanks very much for your help,

    Nick

    I have a COMPAQ X (09) Gaming PC. Some sort of problem occurred sometime after I used Microsoft's SDelete; could no longer boot to Windows XP. Tried a Windows XP Home XP Edition, from another computer, to access the recovery console; the CHKDSK said there was an unrecoverable error. I decided to use the recovery DVD (I believe I used it once before for something minor) since I had transferred most of my data. I used Seagate's SeaTools to check the two hard disks and then ERASEd both. Placing the "recovery DVD" in the DVD drive and making sure the boot defaults were in effect, I continually get "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key".The label on the bottom of the computer contains "DQ091A' which corresponds with the DVD; the paper label sealing the recovery DVD case shows "5069-6498" which I believe to be the part number. How can I get it to work?

    I have about 15-20 VM Guests in my ESX 4.0 U1 test and development lab I want to Thin Provision to save space. I can just SvMotion these between the datastores I have presented to the test and development lab using the Thin Provisioning option. My question is regarding using the shrink option in VMware Tools and sdelete. My understanding is that these utilites basically do the same thing in that they zero out white space. So my thoughts are I should use the shrink option or sdelete if the shrink option is not available before Thin Provisioning the VM's.I am going to set an alarm in vCenter for these datastores but I should have plenty of space after Thin Provisioning. Anyone done a large number of these?

    All of my Datastores have the same block size so I would be using the fs3dm datamover. I thought by using the shrink feature in VMware tools or sdelete that I would reclaim or zero out unused blocks. Is that not the case. I am doing SvMotion from thick to thin.

    DB:2.15:Vmdk Ntfs Deleted Blocks Clean Up sz



    Hi All,

    I have a thin provisioned volume from an Array for a windows VDI environment.

    As many users keep deleting the data from the Guest Operating System (GOS), the NTFS just marks the deleted blocks to be overwritten and the actual blocks are still preserved on the filesystem. The VMDK files keeps increasing over time and every delete at the user end does not reflect at the free space of the array.

    I know of tools like "sdelete" which can do the job of clean up or zeroing the freespace on the VMDK.

    Appreciate if one can share the experiences of using "sdelete" or similar tools to get back the space on the array.

I have also tried the command vmkfstools -i disk.vmdk -d thin newdisk.vmdk within console and still have no luck with it. Is there a more effective way of zeroing out the unused sapce rather the 2 methods mentioned?

    Thank you.

    DB:2.15:Reclaim Space On Thin Provisioning Vmdk xd


    Sorry to jump in late. I was looking for something else and stumbled on this.

    While the method proposed is sound, I wanted to point out that VMFS block size has nothing to do with the block size the guest uses inside the VMDK. Nor does the block size of VMFS5 restrict what you can move into VMFS3 at any block size. Typical guest block sizes are 2k, 4k, or 8k. Yes, there can be others as well, but they are usually much smaller than 1MB. So, you can move a 2TB (minus 512 byte) VMDK from VMFS5 to VMFS3. The VMFS 3 needs to be formatted one of the blocks sizes that allows the file size you need, but you're not restricted to moving from VMFS5 into a 1MB formatted VMFS3 or to the VMDK size that format implies.

    Apologies if I misread your statements.
