<p>Corosync 3 is not compatible with Corosync 2. So once you update
server3 to OLE8, it won't be able to join server4 in the cluster
and take over cluster resources.</p>
<p>If you are restricted to two nodes, you may remove server3 from
the cluster, update server3 to OLE8 and create a one node cluster
on server3. Once you have two one-node clusters, move resources
from server4 cluster to server3 cluster manually. Then you destroy
cluster on server4, update server4 to OLE8, and add server4 to the
new cluster.</p>
<p>Regards,<br>
Tomas<br>
