Hello All,

I've been struggling with a few issues upgrading my 3-node HCI custer from 4.4 to 4.5.

At present the self hosted engine VM is properly running oVirt 4.5 on CentOS 8x stream.

First host node, I set in maintenance and installed new node-ng image. I ran into issue with rescue mode on boot which appears to have been related to LVM devices bug. I was able to work past that and get the node to boot.

The node running 4.5.2 image is booting properly and gluster/lvm mounts etc all look good. I am able to activate the host and run VMs on it etc. however, oVirt cli is showing that all bricks on host are DOWN.

I was unable to get the bricks back up even after doing a force start of the volumes.

Here is the glusterd log from the host in question when I try force start on the engine volume (other volumes are similar:

==> glusterd.log <==

If I run start command manually on host cli:

 gluster volume start engine force
volume start: engine: failed: Post commit failed on gluster1.xxxx. Please check log file for details.
Post commit failed on gluster2.xxxx. Please check log file for details.

I feel like this may be some issue with the difference in major versions of GlusterFS on the nodes but I am unsure. The other nodes are running ovirt-node-ng-4.4.6.3

At this point I am afraid to bring down any other node to attempt upgrading it without the bricks in UP status on the first host. I do not want to lose quorum and potentially disrupt running VMs.

Any idea why I can't seem to start the volumes on the upgraded host?

Thanks!
