I have a very fundamental question. For the two node cluster to work , Is it mandatory that both the nodes are "online" and communicating with each other ? What i can see is that if there is communication failure between them then either both the nodes are fenced or the cluster gets into a "stopped" state (Seen from output of clustat command). Apologies if my questions are naive. I am just starting to work with RHEL cluster add-on. Thanks Jatin </body> </html>
