[ovirt-users] Disks Snapshot

[Ala Hino]

Hi Marcelo,

Is it cold (the VM is down) or live (the VM is up) merge (snapshot
deletion)?
What version are you running?
Can you please share engine and vdsm logs?

Please note that at some point we try to verify that image was removed by
running getVolumeInfo hence, the volume not found is expected. The thing
is, that you say that volume does exist.
Can you run following command on the host:

vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol>

Thank you,
Ala
