Hi Ala,
that did not help. VDSM log tells me that the delta qcow2 file is missing:

Do you have any idea?

Betreff: Re: [ovirt-users] Cleanup illegal snapshot
Indeed, retry live merge. There is no harm in retrying live merge. As
mentioned, if the image deleted at storage side, retrying live merge should
clean the engine side.

Hi,
we are on OVirt 4.0.4. 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."
Did I get it right?

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

Do you have some tip for me?
