Hi everyone.
I'm having an issue with a VM after initiating a snapshot deletion.
Shortly after the deletion started the VM was paused and has not
recovered since, this was over 12 hours ago.
I've dug into the logs and here's some things that jumped out at me:
engine.log
Message: VM XXXXXX has been paused due to unknown storage error.
vdsm.log
Improbable extension request for volume
cb180795-1da8-4a4c-90a9-b42d00485018 on domain
0243ebd9-fd3f-4674-b4e7-05af734280e7, pausing the VM to avoid
corruptions (capacity: 53687091200, allocated: 5750586880, physical:
1073741824, next physical size: 2147483648)
The vdsm.log line I've quoted is repeated approximately every 2
seconds from the first occurrence and is still going. I've attached
engine.log and uploaded vdsm.log to my server [1] as it was 10M. The
VM in question has the ID 184f89f4-8427-4a28-8787-8912f5c5f038.
The VM is still paused and cannot be resumed, seemingly as a
precaution to avoid corruption.
Is there anything I can do to recover the data on the disk? All help
is greatly appreciated.
I'm running oVirt 3.6.6.2-1 on CentOS 7.
Cheers,
Ollie

Thanks, looks like that may be the issue.
Is there any way I can cancel the current operation (it is still ongoing)
so that I can get the hosts upgraded?

Bad news,
the only option that worked in our case was to kill the VM. Afterwards we s=
ometimes had to compare
OVirt DB and storage filesystem status. Because some of the disk snapshots =
completed in between but
OVirt did not recognize. In the worst case we had to fix the state manually=
be moving image files
(on our NFS), merging images on the command line or manipulating the DB.
First shot would be: Stop VM & backup images + snapshots for the recovery c=
ase. Afterwards try to
start the VM and see what happens.
Best regards.

Thanks for your help, Markus. I'll think it through over the weekend
and see if anyone else has any bright ideas to get me out of this mess
and give it a shot Monday.
Have a good weekend :)
