You have self_fence, which should reboot the node instead of power off,
but as you are using drbd - the power off may be caused from drbd instead

the problem i can see in the logs is the line:

when your cluster gets broken, most likely the reason is, there is a

Dear Ganesh,
you do not need to assign the IP via script and there is nothing more to
do with cluster.conf than listing the IP's.
The IP is added to the interface (physical, VLAN, bonded or bridge is not

So, to have 192.168.10.111 added to bo
