Hi Sven, it does looks like a DB issue.
Can u please attach the full VDSM and engine logs to investigate it.
If you want to unlock your disk do the following:
log into the DB : psql -d rhevm -U postgres
and perform the following
SELECT vm_name frim vms where vm_guid = (SELECT vm_guid FROM
vm_images_view where imagestatus = 2);
See if you get the VM which the disk is locked on it.
If so do:
SELECT image_guid from vm_images_view where imagestatus=2;
# Get the guid returned and then
Update images SET imagestatus=1 where image_guid = {The guid which
returned in the last query}
Regards,
Maor
