Adding 2 more nodes to cluster will not change it to a replica 5. replica 3
is a configuration on the gluster volume. I assume you don't need a replica
5, but just to add more nodes (and possibly new gluster volumes) to the
cluster?

Are the repos configured correctly on the new nodes? Does the oVirt cluster
where the nodes are being added have "Enable Gluster Service" enabled?

The host addition flow should take care of installing gluster.
Can you share the engine log from when the host was added to when it's
reported non-operational?
