Hi Gilboa,
Here are some guidelines/checks:
- Are you able to create a 4.5 DC/cluster?
- Host can be Up in the 4.5 clusters only when it reports 4.5 level
compatibility (it's based on RHEL 8.3).
Can you make sure that on all 3 hosts?
- You can upgrade the 4.4 clusters to 4.5 only when all Up/NonOperational
hosts are reporting 4.5 level
- You can upgrade 4.4 DC to 4.5 only when all clusters inside are on the
4.5 level
- A 4.5 host-based on RHEL 8.3 should be fully functional in 4.2/4.3/4.4
clusters

Hello all,
I'm more-or-less finished building a new ovirt over glusterfs cluster with
3 fairly beefy servers.
Nodes were fully upgraded to CentOS Linux release 8.3.2011 before they
joined the cluster.
Looking at the cluster view in the WebUI, I get an exclamation mark with
the following message: "Upgrade cluster compatibility level".
When I try to upgrade the cluster, 2 of the 3 hosts go into maintenance
and reboot, but once the procedure is complete, the cluster version remains
the same.
Looking at the host vdsm logs, I see that once the engine refreshes their
capabilities, all hosts return 4.2-4.4 and not 4.5.
E.g.
'supportedENGINEs': ['4.2', '4.3', '4.4'],
'clusterLevels': ['4.2',
'4.3', '4.4']
I assume I should be seeing 4.5 after the upgrade, no?
AmI missing something?
Thanks,
- Gilboa
