Hi Jatin,

Yes, you are definitely not using it properly :)
Put delay=20, just on one of the devices. This device will wait for 20 sec
(or 10 if you choose), before sending fence request. By that time, the
device without delay will have sent the request and will have fenced it.
Also you only have to modify cluster.conf on one node. Pay attention that
you need to increment the config number.

You can see the current config version with cman_tool, I don't remember the
exact option - status maybe.
You can first verify the syntax of the file, then tell the cluster to
update it - check google for the exact commands for RHEL 6.

Let me know if you have troubles.
