My Situation:
VMWare ESXi 5.0 SSH Access
One of my VMFS volumes is completely full. The VMFS volume has 1 thick provisioned (lazy zero) disk with 1 snapshot on it.
On one of my other VMFS volumes I have enough space for this disk but only if I were to thin provision it.
The VM is off and will remain off until the disk in question is repaired.
My Solution:
I want to use vmkfstools to clone the disk (deleting the snapshot in the process) to the VMFS volume.
vmkfstools -i "/vmfs/volumes/Datastore1/myvm/myvm-0001.vmdk" "/vmfs/volumes/Datastore2/myvm/myvm.vmdk" -d thin
I will then delete the current disk with the snapshot from the vm and connect the newly created thin disk with the same SCSI connector in it's place.
My question is when it is deleting the snapshot does it create a helper snapshot and if so does it place it on the source disk or the destination disk?
