Thanks for your reply,
Do I need a stonith device to use a stonith recourse.

I can't see any stonith primitives in your config. I would guess that the remaining peer is detecting the loss of it's peer and initiating a Stonith action. Since there is nothing to stonith the lost peer then there will be no confirmation to the remaining peer that the failed node is dead. Until this confirmation is received I'm pretty sure that the failover won't happen.

I have setup 2 servers so that I can replicate a filesystem between both servers using drbd. I configured a drbd , filesystem, IPaddress, pingd resources, I also have an lsb resource to start icobol.
I can stop & start the resource group & migrate the resource group between servers using pacemaker GUI. But if I power down or take one of the servers of the network the resource group doesn't fail over to the other node.
Hopefully someone can point out to me where I have make a mistake or not configured sometime.
. Pacemaker config, drbd.conf & openais.conf are below
