I though that to, but I think is more. When I run: vdsm-tool
dump-volume-chains "sd_id" I get:
image: ad23c0db-1838-4f1f-811b-2b213d3a11cd

15259a3b-1065-4fb7-bc3c-04c5f4e14479 is the snapshot.

Hello everybody,
last night my backup script was not able to finish the backup from a
VM in the last step of deleting the snapshot. And now I also can not
delete this snapshot by hand, the message says:
VDSM onode2 command MergeVDS failed: Drive image file could not
be found: {'driveSpec': {'poolID':
'c9baa5d4-3543-11eb-9c0c-00163e33f845', 'volumeID':
'024e1844-c19b-40d8-a2ac-cb4ea6ec34e6', 'imageID':
'ad23c0db-1838-4f1f-811b-2b213d3a11cd', 'domainID':

'96c7003f-e111-4270-b922-d9b215aaaea2', 'reason': 'Cannot find

The full log you found in the attachment.
Any idea?
Best regard

Hello everybody,
last night my backup script was not able to finish the backup from a VM
in the last step of deleting the snapshot. And now I also can not
delete this snapshot by hand, the message says:
