Seems like this is a libvirt/qemu issue:
2022-08-30 08:18:31,121+0000 ERROR (libvirt/events) [virt.vm]
(vmId='53adff44-8506-41e7-86d1-5a6ca760721e') Block job
89eab626-9c32-48fb-b006-dbc09cb0026a type COMMIT for drive sdb has
failed (vm:5972)
Can you also share the qemu/libvirt logs?

Hi Giulio,
To get to the root cause of this problem, I think it is best to look
at the engine and vdsm logs
from the initial failures with vprotect. You can open a new bug in BZ
and place the relevant logs there.
Thanks,
Mark

Hi folks,
since some month I have an issue with snapshot removals (I have
storware
vprotect backup system, heavily using snapshots).
After some time spent on a bugzilla
(https://bugzilla.redhat.com/show_bug.cgi?id=1948599
<https://bugzilla.redhat.com/show_bug.cgi?id=1948599>) we discovered
that
my issue is not depending on that bug :-(
So they pointed me here again.
Briefly: sometime snapshot removal fails, leaving snapshot in
illegal
state. Trying to remove again (via ovirt UI) keeps failing and
doesn't
solve. The only way to rebuild a consistent situation is live
migrating
affected disk to another storage domain; after moving the disk,
snapshot
is no more marked illegal and then I can remove it. You can imagine
this
is a bit tricky, specially for large disks.
In my logs I can find:
2022-08-29 09:17:11,890+02 ERROR

My setup is ovirt-engine-4.5.2.4-1.el8.noarch, with hypervisors
based on
oVirt Node 4.5.2 (vdsm-4.50.2.2-1.el8).
Thank you in advance.
