  • 1.  Snapshot deletion - Advice needed

    Posted Oct 29, 2012 01:23 PM

    I have a VM which is currently running 5 snapshot and I have to delete All, This is only VM in the datastore and total size of the datastore is 1 TB left with 60 GB of free space.

    We are currently running ESXi 4.1 Update 3.

    We have 6 disk attached to the VM and all are THICK provisioned disk, Some disk are attached to the VM after 1 or snapshot are taken.

    Would like to know if its Ok to do delete all and do we have sufficient free space on the datastore and is it better to shutdown the VM while deleting the snapshot.

    Running "Delete All" with the VM powered on will temporarily create a "Consolidate-Helper" snapshot for each virtual disk. If you can ensure these snapshots won't grow too much and consume the remaining disk space, you can run delete all with the VM powered on. To be on the safe side, consider to run "Delete All" with the VM powered off as this will not require any additional disk space on the datastore. If you decide to delete the snapshots with the VM powered on and you are going to run out of disk space, you could delete the "...-SnapshotX.vmsn" files from the datastore. These files are only required in case you want to revert to a snapshot.
