  • VM Snapshots not in snapshot manager but present on datastore

    Hi,

    Im new to the site so not sure of the formalities...........

    Setup
    ======

    Host - ESX 4.0.0, 261974
    Datastore - Fibre attached
    VM - Windows server 2008
    Number of Virtual Disks = 1

    Number of snapshots showing in vm folder on the datastore - 5 However none of them are showing in VM snapshot manager.

    Scenario
    ========
    The issue has arsien due to a scheduled snapshot being invoked by Commvault and not enough space resided in the datastore to complete it. So the vm on this datastore went into an orphaned state.

    I added more space to the LUN and increased the datastore accordingly. I was then able to power the machine on.

    When I attempted to remove the snapshot from the snapshot manager i noticed it didnt appear in the manager but is still in the vm folder on the Datastore and the vm is still currently writing to a snapshot vmdk.

    Steps taken so far to resolve
    =====================

    I have taken another snapshot and then deleted all snapshots from the manager however this didn't resolve the issue.

    I have taken another snapshot this time selecting "Quiesce guest file system " however I have insuccifiecnt space on the datastore to complete this. (I can't allocate anymore space to the Datastore)

    I currently have the vm powered off until I can rectify this as I will run out of space in the datastore if I left it on as it is still writing to snapshot 00005.vmdk

    Next Steps
    ===========

    I would like some advice on how to clear these snapshots files and return to writing to the original base vmdk file.

    Many Thanks in advance

    If you want to commit the delta files try this:
    http://kb.vmware.com/selfservice/mic...rnalId=1002310

    Maybe this might work as well
    http://sostech.wordpress.com/2011/02...esx-snapshots/

    Or simply try to clone the VM to an other datastore (with space), which should commit all the snapshots as well.

      Thanks for the reply.

      I used the command line to create a snapshot and delete all snapshots.
      => This activity completed successfully however it didn't resolve my issue. I now have 6 snapshot files in the vm folder in the datastore and the base disk is not the disk that the vm is currently writing to.

      What was strange was when I ran

      # vmware-cmd /vmfs/volumes/UUID/VMNAME/VMNAME.vmx hassnapshot

      it returned a "0" value - however this is contray to what I know.

      I am currently cloning the machine to another datastore as indicated in your last post - hopfully this will resolve the problem.

        The clone to a vm on a different datastore worked.

        It failed the first time though when the source vm was powered off, it subsequently worked the 2nd time when I powered the source vm on.

        (The error messgae was it couldn't access the last snapshot vmdk file 0006)
