manually delete 'stuck' abandoned snapshots??

  • 1.  manually delete 'stuck' abandoned snapshots??

    Posted Feb 26, 2015 04:39 PM

    I have a few vSphere 5.5 VMs with 'old' snapshots that don't consolidate from Snapshot Manager.

    That is, I choose 'Consolidate' and vCenter a few seconds later says it is completed but the snapshot is not gone.

    Is it okay to go into the datastore and manually delete these 'stuck' abandoned snapshots??

    They don't appear at all in Snapshot Manager.

    One snap is a few months old, the others a few days old.

    Thank you, Tom

    Try take a new snapshot and after snapshot task complete, using the snapshot manager select "Delete All".

    If you still see disk "zombie" snapshot, first check if virtual machine is not pointing to them and move them to another folder, and after some days if everything is ok, you can delete them manually.

    How would I know the VM is not 'pointing' to the zombie snapshot??
    They are all zombie snapshots, they don't appear in Snapshot Manager.

    Thank you, Tom

    To be safe you may use RVTools which lists zombie files very reliably, or you may check the VM's current vmware.log file to see whether the snapshot files are still mentioned (in use). In case you are unsure, move the files to a new folder, and if the VM still boots without issues, you may delete the moved files in a second step.

    I did try RVTools, it does not see any of the snapshots...

    I'll try again though.

    Thank you, Tom

    Check the "Health" tab, to see whether it reports zombie files. Anyway, the most secure way is to check the log file(s).

    Finally getting back to this, what would I look for in the vmware.log file???
    It's quite large.

    That is, I can find referencies to the 'zombie' snapshot in the log file, but I do not necessarily know what to look for that signals it is no longer pointed to, wanted, needed, etc.

    Thank you, Tom

    The vmware.log file (make sure it contains entries with current time stamps) contains all kind of information, including the virtual disk (.vmdk) files which are in use. As mentioned before, if you think that some of the files are not in use, move them to another folder instead of deleting them right away!

    For the VM I'm investigating, the 'zombie' snapshot is no longer mentioned after 2/22/15 so I assume it's no longer used, moved it to a folder, will leave it a couple days, then remove the folder...then have several more VMs to do the same thing on...

    Thank you, Tom

    RVTools worked for getting rid of some of them.

    VMware support helped with getting rid of the rest, one of them took awhile.

    Basically move the 'stuck' snaps to another folder, let it sit awhile, then delete the folder...

    Snaps all gone etc.

    RVTools 3.7 works much better than older versions.

    Thank you, Tom
