Adding to the point 3 below -> Since the score of Node 1 after a reboot is 5000, more than that of the other node, it seems to force heartbeat to switchover a running resource on node 2.
We want to tell heartbeat not to do that because upon a reboot, Node 1 should silently come and join as a standby Node and wait to run the resource when Node 2 (the current Active) fails to run it. So basically, we want scores to come into picture only in the case of failure and not in the case of a new node coming into the cluster with a higher score.
