Question about thin provisioned disks

• Considerations, concerns or questions RE Thin Provisioning.

  Hey all,.

  I have a question about a provisioning.  It seems that we have a debate about our team on the issue of whether we should use it as a policy.

  We have a cluster 2 ESX 4.0 and ESX 3.5 environment all connected to EMC via NFS storage.

  What should concern us, is there on the virtual computer performance problems if the storage starts to develop?  Should do us as a global policy or a policy according to the needs?  Can someone shed some light on this?

  Hello.

  The biggest concern with a provisioning is that you have to manage it.  It is still something to keep an eye on.  Implementation of the alarms is the key, if you have vCenter.  For the workloads highest performance, there will be some additional latencies involved.  The thin disks will not work with VMware FT either.

  Good luck!

• Question of thin provision

  I'm new to ESXi so I hope that this question has not been answered before but I couldn't find anything about it.  I have a box of ESXi 4 with some VMS with placed disks in service purposes.  When I look into the virtual computers tab of the used space on some of them is presented as a couple KB.  I know it must be less than the space put into service and that's the whole idea of Thin Provisioning, but this tab does not appear to take into account what the VM actually uses, because it appears only a few KB.  What is the problem?

  Ben

  Hello

  for example, you can update (click on refresh word/link) in the summary of the VM tab.

  Also, you can do the same thing in the tab displaying data warehouses.

• A few questions about Toshiab reocvery disk for Satellite P300-133

  Hello guys,.
  I had a few questions about unpleasant surprises of recovery:

  (* 1) * I just make recovery DVD using Toshiba Recovery Disk Creator and he asked initially for 2 DVDs - but when one has been done it does not require a second blank DVD. Is it possible all the Windows Vista system files to write on 1 DVD?

  (* 2) * if I could reinstall Windows Vista using recovery of HARD drive option (by pressing F8) without using the recovery DVD?

  (* 3) * HARD drive partitions that will be formatted (just system C: or C: and E :) using HARD drive recovery?

  (* 4) * what is DVD - Image of the hard drives or the installation of Vista recovery files?

  Its pretty bad idea to not include BONES on DVD when I paid for it.
  Thanks for all the Toshiba problems :(

  1. I think the recovery disk creator means 2 CDs. I also have a Portege M700 with Windows Vista and a DVD. I got it and after that, I have a clean install of Vista with all the drivers and tools of Toshiba. Nothing is missing.

  2. Yes, you can reinstall Vista using recovery of HARD drive option when you press F8 at startup. You don't need the recovery DVDs, but you should create a when your HARD drive get some errors or something else. If you need a new recovery DVDs, you paid for one.

  3 HARD drive and complete partitions will be formatted, so backup your data first on a DVD disk external DRIVE, USB stick or something else.
  After the reinstallation, you have factory settings.

  4. the recovery DVDs is an image of the HARD disk on the factory settings. If you perform a recovery, there are all the drivers and tools are already installed. Of course, on the disk are files of installations of Vista, but you can use this DVD on your Satellite P300. The disc cannot be used on another Satellite or on a PC.

  If you have any other questions, take a look in the user manual. There are a number in the formations of the recovery. It s in Chapter 3.

• Backup errors with backup of thin provisioned disks on ESXi 5.1

  Hello

  I try to set up a backup solution for two servers in ESXi 5.1. (free version).

  I have installed and configured the ghettoVCB successfully and everything seems to be ok.

  However, when I start to create a backup, the process would end with an error :-(

  It didn't matter if the server is enabled or disabled, I get the same result.

  All data warehouses are local, 2 x free WD500GB with plenty of space.

  There is no snapshot, anything that could (in my eyes) prevent a good backup.

  The server works perfectly, when turned on.

  I'd appreciate any useful comment. Thanks in advance! The log is attached.

  > However, when I start to create a backup, the process would end with an error :-(

  This is not correct.  Depending on your position, you've got to 66%, until he ended with an error.

  I have the same problem. In my case, I make a virtual disk full and mount it with Server 2003 for project a NFS volume.  I use GhettoVCB, as you do.  It uses the standard vkmfstools in the script to make the clone/backup.  I have proven that the problem also occurs when you use the command line vkmfstools.  GhettoVCB has the bad habit of you cache the error code.  The error code is he ran out of disk space, which we both did not happen.  Once the problem occurs, the only way I could fix is to delete the virtual disk and start over, however, the problem will come back.  The problem didn't surface until what I moved to ESXi 4.0 5.1 on the servers.  Through this process, the hardware off the VMS version did not change, nor dare, because I may need to take 5.1 and back to 4.x.

• Is it possible to migrate a virtual machine to thin provisioned disk?

  I have about 100 VM in a resource pool dedicated to called "Archive"... Well, archiving.  These virtual machines are currently powered off but every now and then we will get pulled for a developer to work on (they are for the most part, the virtual computer with client customizations if they are changed about once a year).  I'm quickly running out of space on this SAN but all discs are thick provisioned and using the disc is maybe 20-30% on average.  Also, I want to move them to a new large store of data I created for them.

  Of course, I choose Migrate & gt; Change store data & gt; Thin provision in vSphere Format and I'm done.  However, it would be nice to not do this 100 times.

  Move-VM does not seem to be capable of this, and I have not been able to find a workaround.  Is there a way to convert the thin and then perhaps Move-VM? Or I'll just on this all wrong.

  Thank you!

  You can try this script?

  He's moving vms to data store 'EMCSAN:Datastore01' trying to change the format of storage for Thin

  $dsView = Get-Datastore -Name "EMCSAN:Datastore01" | Get-View -Property Name
  
  Get-VM  | % {
  $vmView = $_ | Get-View -Property Name
  
  $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec
  $spec.datastore =  $dsView.MoRef
  $spec.transform = "sparse"
  
  $vmView.RelocateVM($spec, $null)
  }

• Can't P2V to a thin provisioned disks copied non-zero'ed crashes?

  I need P2V a server that has recently had a lot of deleted data.

  If a make my thin target supplied disk, will be the layout of converter for these unused space but not zero would be blocked?

  As a question, making the thin target instead of thickness negatively influence the performance of the copy?

  Yes. Use sdelete on Windows or dd on Linux, to zero free space before you run the P2V.

• question about creating virtual disks on my MD3220i

  I create a virtual disk where I put a SQL Server and it asks me to

  Choose the type of virtual disk IO characteristics. The file system (typical), database, multimedia and Custom options.

  I think the selection of data because it is a SQL Server. However I'm not sure because I have not much of

  experience with this. My question is that one should choose or perhaps not even matter?

  Thank you

  Being that the VD will be strictly for SQL, then you can go ahead and select the database option. Any other time, you must select the typical option. Please let me know if you have any questions or concerns.

• Cannot increase the size of thin provisioned disk

  Hello

  I am currently using vSphere, and I have a server that I am trying to increase the space allocated 40 GB to 50 GB. The problem is the option to increase the provisioned size is grayed out and I can't seem to understand this.

  I already checked to see if there is a snapshot, there are none.

  I also checked that the drive is a scsi and NOT an IDE drive.

  I'm fresh out of ideas and google searches return only guides on how to do what I've done, so any help is appreciated. Attached are the parameters of the hard disk, and the Snapshot Manager shears.

  Welcome to the community,

  According to the file name of the virtual disk in the first screenshot, the virtual computer runs on an active snapshot. The Snapshot Manager can not always show all snapshots, then take a look at the data store of the virtual machine to see if there are files... - 00000 x hard (snapshot).

  To get rid of the snapshots, create a new snapshot and run "Delete All" since the Snapshot Manager to commit all the snapshots on the basic disk.

• Thickness as Thin provisioned disks

  I had a strange situation this morning and I hope someone can shed some light for me.

  I have a virtual server with several big (300 GB and 200 GB) HARD drive.  The two HARD drives were created as thick put in service, as I recall they show also thick configured in the properties of the server.  The data is stored on an iSCSI SAN.

  This morning, I came to find one of my virtual servers had been frozen as he had ' not enough space to write.  I looked in the store and found the property that the disks have been configured in thick they are infact behave more like thin disks.  In the store, they show that 110 and 202 instead of 200 GB and 300 GB.

  Any thoughts?

  The screen capture, it seems that your VM has 3 virtual disks (~ 256GB, 60GB, 350 GB). The size of the snapshot files (the screenshot doesn't show timestamps), I guess that there has been a problem some time ago (one of the snapshots already is ~ 67 GB in size) with delete snapshots after a backup operation.

  You must take immediate action to get rid of snapshots! However, to know whether to save just delete catches instant in the Snapshot Manager (it can currently not display any shots even if you have a little) I need to know what version/buils of ESX (i) you are running and the amount of free space on the drive you have on data stores different (the virtual disks are located on different data stores)!

  Currently, the virtual machine works without problems?

  Please join (not paste) the last file vmware.log file for the virtual machine (see the screenshot).

• Question about the new disk on the Satellite A100 (PSAA9)

  Hello!

  To extend time to work on the battery to make hard disk access faster and to extend the disk space, I upgrade my hard drive.
  I found this beautiful disc:

  Link:
  [http://www.seagate.com/ww/v/index.jsp?locale=en-US&name=Momentus_7200.2_SATA_3.0Gb/s_160-GB_Laptop_Hard_Drive&vgnextoid=546207c8108dd010Vgn VCM100000dd04090aRCRD & vgnextchannel = c021a47948a3d0 10VgnVCM100000dd04090aRCRD & reqPage = model]

  This hard drive is compatible with my Toshiba Satellite A series and you have a better solution please respone?

  Love, peace,
  Vasja.

  The HARD drive is very nice.
  The A100 PSAA9 series supports SATA 2.5 hard drives.
  The 160 GB should also be compatible because some units of the A100 series were already equipped with 160 GB hard drives.

  I think it s a HARD drive supported.

• Question about data storage disk and its related material

  Question1.
  I would like to know what storage device that I use for installation at home of RAC?

  FireWire. Nothing else really which is pretty cheap for a "budget home" and always meets the needs of Basic for a RAC storage. You can pick up 1 TB and more big disk Firewire 800 external, with 2 ports - allows to connect two machines on the external drive at the same time.

  It is "sort of" supported by Oracle off-production - or has been in the past.

  Not sure if Solaris kernel Firewire driver required to support this well - only made on Linux myself.

  Question2.
  What additional hardware (cards) should I add to both nodes to connect to this network storage system?

  PCI FireWire cards if you have not already shipped Firewire 800 ports on these 2 systems.

  PS. had a quick look at support.oracle.com and found the following note: ' + how to install a cluster using firewire to access a shared disc on RHEL4/EL4 [ID 433889.1] + '. Nothing on Solaris if. Why Solaris btw? Especially on x 86? Linux is a much more commonly used o/s for RAC clusters.

• Question about adding additional disks with voting rights (AIX cluster)

  I maintain a database cluster Oracle 10 g RAC running on AIX servers and I would like to add another disk to vote. I intend to use the following, executed command as root: crsctl add css votedisk device_pathname.
  
  This command can be performed while the database and cluster services are active, or do I have to stop both before changing the configuration of the cluster?
  
  Thanks in advance for any help!

  as stated in the doc:

  * "" using the - force option while any cluster node is active can corrupt your configuration. "*"

  MetaLink Note 428681.1 (updated Dec 2008) clearly said that the crs must be stop in 10 g on all nodes before making any changes on the drive to vote

• Add thin provisioned disks

  I need to create a script to do the following steps:

  1. turn on a virtual machine

  2 remove the disc

  3 Add the service end disc

  4. turn on.

  I need to exclude VMS with snapshots.

  Should I call if I want only to a certain group of VM from a .csv file?

  If there is no agreement on behalf of the guest that you can use to select these 60-70 guests then you better use a CSV file.

  The script would then become something like that

  Import-Csv "C:\vms.csv" | %{
       $vm = Get-VM $_.Name
       Stop-VM -VM $vm -Confirm:$false
       Get-HardDisk -VM $vm | Remove-HardDisk -Confirm:$false
       New-HardDisk -VM $vm -CapacityKB (20 * 1MB) -ThinProvisioned:$true -Confirm:$false
       Start-VM -VM $vm
  }
  

  you use a file CSV with this layout provided

  Name
  guest1
  guest2
  ...

• Question about hdd comments

  Hello

  My name is Tigran.

  First of all excuse me for my English.

  I have a question about comments HDD.

  I have a windows 7 machine 19.ne 60 GB provisioned thin disc comments.

  Today, I delete some files from the guest operating system and I free on about 20 GB of disk space. Now in my guest os used space on disk is of about 30 GB, but in vcenter disk space is always 50 GB. I understand that thin provisioned disk space grows when add us files to this disc, what would you say to resize to the bottom of the disk space?

  Thanks in advance.

  Unfortunately a virtual disc service end increases only in size if necessary, but does not automatically decrease if less space is needed for the guest operating system. If you want or need to reduce the size of the virtual disk, would be to run VMware Converter and make a volume base conversion (rather than on the disk).
