Might it be a good idea to stick them in the same cluster, but with different failure domains? That way, chances are higher of staying quorate. Just a thought...

I don't know if GFS2 is the best way to share data among your VMs. But if you go for GFS2, I suppose the clusters should be different : one cluster for the hosts, and one cluster for the VMs having a shared disk with GFS2. They have different purposes, you should not mix them. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
