[ovirt-users] VM has snapshots with disks in illegal status

Hi! I've testet a backup solution which turned out to work not as expected. It left some VM's turned off which cannot be restarted. When trying to delete the snapshot(s) of the vms following error message occurs: "Cannot remove Snapshot. The following attached disks are in ILLEGAL status: System, Disk2 - please remove them and try again" Also I cannot detach any disk because of: Cannot remove Snapshot. The following attached disks are in ILLEGAL status: System, SRV_Metrics-Store_Disk1 - please remove them and try again. I already tried via "unlock_entity" script to remove either the snapshots or the disks (after backing them up) and via CLI but without success (same error message). Any idea on that?
