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 merg=
e them again. Assuming the previous live merge of the snapshot successfully=
completed but the engine failed to get the result, the second live merge s=
hould do the necessary cleanups at the engine side. See https://bugzilla.re=
dhat.com/1323629
Hope this helps,
Ala

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>

Hi Markus,
Few errors are expected. Do you still see the snapshot in the GUI?
Can you please send engine logs as well.

Hi Markus,
I'm sorry for this confusing log, Vdsm is treating a missing volume
as a horrible
error is a bug, this is expected condition when you query volume info.
We also log 2 exceptions instead of one.
Would file a vdsm storage bug for these issues?
Thanks,
Nir
