Shani, 1. I created a new 4.5 cluster with the same CPU (Secure Intel Cascadelake Server Family) and platform type (Q35/BIOS). 2. All 3 hosts are 8.3, but report 4.4 compatibility. 3. The only reason I attempted to upgrade the cluster was simple: The cluster state kept on dropping down to "unavailable" (even though all 3 hosts are up) and I was offered to upgrade the cluster to v4.5. - Gilboa On Wed, Dec 16, 2020 at 1:28 PM Shani Leviim <sleviim@redhat.com> wrote:
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?
