As explained the situation is as follows: - On Disk we have the base image and the delata qcow2 file - Qemu runs only on the base image - The snapshot in Qemu is tagged as illegal So you say: "Just retry a live merge and everything will cleanup."

Hi,
if a OVirt snapshot is illegal we might have 2 situations.
1) qemu is still using it - lsof shows qemu access to the base raw and t= he delta qcow2 file. -> E.g. a previous live merge failed. In the past we successfully solved that situation by setting the status of the delta im= age in the database to OK.
2) qemu is no longer using it. lsof shows qemu access only to the the ba= se raw file -> E.g. a previous live merge succeded in qemu but Ovirt did no= t recognize.
How to clean up the 2nd situation?
It seems that you will have to first clean up the engine database to remove references to the snapshot that no longer exists. Then you will need to remove the unused qcow2 volume.
Unfortunately I cannot provide safe instructions for modifying the database but maybe Ala Hino (added to CC:) will be able to help with that.
Do you have some tip for me?
One you have fixed the DB you should be able to delete the volume using a vdsm verb on the SPM host:
# vdsClient -s 0 deleteVolume <sdUUID> <spUUID> <imgUUID> <volUUID>
