Hi

I am using a two node cluster to achieve high availability.

I am basically testing a scenario where in if i shutdown my node 
(node-1) then the other node (node-2) should start functioning like 
node-1. Currently what i am observing is that the entire cluster gets 
into "Stopped" state.

Here is my cluster.conf file
