Hi
Today, I upgraded oVirt from 4.3 to 4.4.3.
After the upgrade, I upgraded the compatibility from 4.3 to 4.4.
I noticed that the cluster config is offering me another upgrade of the
compatibility to version 4.5.
Up until now, I was under the impression that the compatibility version
must match the oVirt version.
I am now reluctant to upgrade the compatibility to 4.5, while my oVirt
version is still at 4.4 (there is no oVirt 4.5 at this time).
Is it safe to upgrade the compatibility in any case, or are there
certain circumstances, where we should refrain from upgrading it?
I wasn't able to find anything in the documentation.
Kind regards
Toni Feric

Just to confirm i face similar problem.
Yes i saw that warning too : "Upgrade Cluster Compatibility Level" to
upgrade the Cluster to version 4.5.
Though when i try to do that there are a lot of errors.
In GUI :
Error while executing action: Cannot change Cluster Compatibility Version to higher
version when there are active Hosts with lower version.
-Please move Host host1, host2, host3 with lower version to maintenance first.
In engine.log :
WARN [org.ovirt.engine.core.bll.UpdateClusterCommand] (default task-163)
[2c681b74-8666-4f2f-b2e0-6b20e98f417e] Validation of action 'UpdateCluster' failed
for user admin@internal-authz. Reasons: VAR__TYPE__CLUSTER,VAR__ACTION__UPDATE,$host
host1, host2, host3,CLUSTER_CANNOT_UPDATE_COMPATIBILITY_VERSION_WITH_LOWER_HOSTS
I did not find any documentation for 4.5 cluster compatibility, so i like as well to
understand why is that option present there.
It will be used when ovirt 4.5.x will be released ?

Hello,
To upgrade to cluster 4.5 you need a 8.3 host.
I guess still CentOS 8.3 is not available. I am not sure on CentOS 8.3
availability.
If it's available please make sure your host is upgraded to 8.3 .

I’ve also faced this issue, which is surprising since I used an ovirt node download for
4.4.
How did you resolve it? How can you upgrade to CentOS 8.3 or downgrade the cluster?
Thanks,
Chris.
