did you restarted the cluster after added the delay parameter?

Ok , i tried with delay but it has not helped. I guess i have to try using
quorum disk now.

Thanks

You may need to delay the fencing ( delay=seconds ) or use quorum disk if
delaying the fencing doesn't help.

Hi

I am using a two node cluster using RHEL 6.5. 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
