Thank you so much for the update Pavel!
Ok, we will try to check the DB leftovers and will share with you if we find
something new. But so far we haven??t seen the same problem again.
Best regards!

Hi,After investigating the logs I believe that there were few issues
that might have caused this unstable behavior.
1) Looks like the DB still contained some leftovers from the already fixed bug
which was causing duplicate entries. Even after the date of engine upgrade I
still saw some "Duplicate key" errors. I suggest cleaning the DB (if that is
possible).
2) Also saw a few other known (and already reported) issues that also might
have caused the problem. The issues are going to be fixed in the
coming 4.4.9 version, resulting in more stability.
I asked our QE team to inform me if they encounter this 'disks stuck in
FINALIZING' issue, so I'll be able to try and investigate it locally.
But again, this issue might be caused by either some DB leftovers or issues
that we are already WIP fixing them.
If you opened a bug, please send the link to it here.
Thank you in advance.

Hi,Just a short status update FYI.
The issue is not forgotten, I'm looking at it.
Found in logs a few known issues that are gonna be fixed in the next version,
but still not sure that the issue you described will be fixed by them.
WIP, will continue updating.
Thank you!

Sorry I was trying to open a new thread for this issue, but it seems I
failed to submit. Here let me explain how the issue is reproduced.
It??s a regular backup by using CBT+imageip API, after a series of successful
backup, at one of the backup session beginning, when we try to obtain the VM
config and the snapshot list (obtain snapshot list can determine the VM virtual
disk format is RAW or QCOW2) by using `GET vms/<vm-id>/snapshots`, but get
the following error.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<fault>
<detail>duplicate key
acf1edaa-e950-4c4f-94df-1bd6b3da49c1 (attempted merging values
org.ovirt.engine.core.common.businessentities.storage.diskimage@5103046c and
org.ovirt.engine.core.common.businessentities.storage.diskimage@d973046c)</detail>
<reason>Operation Failed</reason>
</fault>
After this, on oVirt engine web console, the VM show 2 disks (actually it only
has 1) , and the disk status always showing ??Finalizing??, it??s been more
than 30 hours now, and during this, cannot modify VM disk or take snapshots.
Before upgrading oVirt engine to 4.4.7.7-1.el8 this problem happened
frequently, after upgrading, the frequency is reduced.
Here I??m adding the engine logs and vdsm logs.
Engine

VDSM

Thanks & regards!

The problem occurred yesterday, but we waited for more than 20 hours, still 2
disks and in Finalizing state.
If the image transfer is "finalizing" it means the image transfer is
trying to finalize, but the operation could not complete.
In this phase the disk remains locked, and it should not be possible
to start a new image transfer
(e.g perform another backup).
Engine and vdsm logs should explain why the image transfer is stuck in
the finalizing phase.
Can you add detailed instructions on how to reproduce this issue?
