Hi,
I have two questions. I have a cluster with 2 nodes, both have local storage,
one GlusterFS (for future upgrade) and one NFS.
1. I have slightly different versions of KVM and VDSM on both nodes. Can this
lead to problems? If so, can I downgrade , eg yum history rollback the latest
updates?
2. On the other host, I have self-hosted oVirt with GlusterFS and am wondering
what would be the proper workflow to upgrade VDSM and KVM ? Do I have to
shutdown the storage first? If so, does that mean shutting down all the VMs?
You would need to put the hosted engine to maintenance mode, stop vdsm,
stop gluster volume, update vdsm , start gluster volume, start vdsm.
Any help on this topic would be very welcome,
P.s.: I know our setup is not ideal for HA and resilience, but we do with what
we have :)
