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!

Pavel

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.

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?
