I have come across a number of environments where mystery “snapshot” files exist – they are not seen in snapshot manager, running a consolidation them doesn’t help, creating a snapshot (with memory, or guest OS quiescing) then running “Delete All” doesn’t resolve it, but some applications still think a snapshot is there.

This will just reduce the VMDK’s usage on the VMFS datastore NOT resize the “provisioned size” of a thin disk. To shrink a VMDK we can use an ESX command line tool “vmkfstools”, but first you […]
