[ovirt-users] Cannot upgrade cluster to v4.5 (All hosts are CentOS 8.3.2011)

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
