Hi Markus, What's the version that you are using? In oVirt 3.6.6, illegal snapshots could be removed by retrying to live merge them again. Assuming the previous live merge of the snapshot successfully completed but the engine failed to get the result, the second live merge should do the necessary cleanups at the engine side. See https://bugzilla.redhat.com/1323629 Hope this helps, Ala On Thu, Oct 6, 2016 at 11:53 AM, Markus Stockhausen <stockhausen@collogia.de

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
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 image in the database to OK.
2) qemu is no longer using it. lsof shows qemu access only to the the

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>
