[ovirt-users] Re: oVirt 4.2 how to upgrade

Theoretically you most probably can, but you take the risk of being vulnerable to split-brain. Keep in mind that you can:- update gluster to the same version that is used on oVirt 4.4- update oVirt to 4.3.10 as this is the most tested migration scenario- reduce the volume and remove that 3rd node (don't forget to peer detach)- reinstall with EL8 and install gluster (same version) again. Add the brick and qait for the heal- create a new volume for the new HE- Stop the old HE and deploy the new one from the backup- Add the hosts to the new HE and migrate some of the VMs to free one of the old hosts- Reinstall the remaining hosts (one by one) to EL8 Best Regards,Strahil Nikolov On Thu, Jun 24, 2021 at 14:28, Fedele Stabile<fedele.stabile(a)fis.unical.it> wrote: I have a 3 node oVirt 4.2.1 cluster, i'm using a self-hosted engine architecture and storage-engine is on a glusterfs replica 3 of the cluster. The oldest CPU is SandyBridge family (E5-2609) and incidentally it has connectivity problems with IPMI NIC, but Hosted Engine HA is enabled and working. May I reduce the glusterfs replica to 2 and use one of the 3 nodes to begin the installation of ovirt 4.4 on that node?
