Hi I am not sure how split brain works in ovirt. In other cluster solutions you can have an even number of nodes such as 4, 6 , 8 etc. All nodes writes to quorum disk, say we have four nodes if one node goes down the other three will vote
node 1 says I see node 2 and 3 but not 4 node 2 says I see node 1 and 3 but not 4 node 3 says I see node 1 and 2 but not 4 So all three votes node 4 must leave the cluster and the split brain is solved On Tue, Mar 5, 2024 at 10:58 AM Youssef Khristo < youssef.khri...@elsewedyintel.com> wrote: > The split-brain explanation makes a lot of sense, so I changed the HE VM > deployed hosts from 6 to 5, as well as set an Affinity Group with soft VM > to Hosts enforcement for the other VMs (since HE is managed separately) for > 5 hosts, with a similar Affinity Label, and I ran a test where I perform > outstanding upgrades from the Administration Portal on any host (where I > chose that the host be rebooted), the host is moved to maintenance, updates > are installed and host is rebooted, I still get the same issue where the > entire cluster with every single VM including HE goes down.
