[Pacemaker] failover problem with pacemaker & drbd

Hi
 
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
