Dear all, 

FYI, after upgrading oVirt engine to 4.4.7.7-1.el8 the chance of reproducing this issue is reduced, but it still persists.

Can you please open a bug for it and mention the steps you did to reproduce the problem?
Also, please include all the relevant logs in the bug.

Benny/Pavel, is there a WA for getting out of this issue besides removing the entry from the DB?

 

The oVirt node version is also 4.4.7, the virtual disks are stored in iSCSI LUN.

The problem occurred yesterday, but we waited for more than 20 hours, still 2 disks and in Finalizing state.


At this moment, we are unable to check/delete snapshots, or perform backups.

Please let us know if we can do anything to help with the debug.

Thanks & regards!

As +Michal Skrivanek already replied, this issue cause by - https://bugzilla.redhat.com/show_bug.cgi?id=1980428.

It is already fixed in RHV 4.4.7 and on the master branch.
+Sandro Bonazzola, did we include it on oVirt 4.4.7 also? 

$ git tag --contains 6cd8bc532b0a4a6839ed667c67489256ae9ff5b9
ovirt-engine-4.4.7.7

It was shipped on July 20th but I don't see an announcement for it. +Lev Veyde ?

Dear team,

We had implemented CBT support for RHV and oVirt in our new version, but when testing we encountered problems of obtain VM increments and also had abnormal with the VM virtual disks.

Our testing environment as below:
OS Version: RHEL - 8.4.2105.0 - 3.el8
OS Description: oVirt Node 4.4.7
Kernel Version: 4.18.0 - 315.el8.x86_64
KVM Version: 6.0.0 - 19.el8s
LIBVIRT Version: libvirt-7.4.0-1.el8s
VDSM Version: vdsm-4.40.70.6-1.el8

One of the problem is after a successful backup, the VM which gets only one virtual disk will get 2 identical virtual disks marked as Complete on oVirt engine web console, like shown below.

The additional disk might disappear after a while, but before it’s gone there could be a lot of problems with the VM.

1. We cannot perform a new backup, the backup will fail directly.

2. The VM itself will run into exception, we cannot even power it off, and it will also probably get crashed.

3. If the VM was initially powered off, after backing up, we cannot power on the VM.

And there could be some other problems related with this, is this normal or there’s something we did wrong?

Thank you in advance for your help!
