Mayank, the message you're seeing is logged at the very beginning of the
bootstrap of the cluster.

The resource agent has to determine what is the last transaction on all
the galera nodes before it can elect a bootstrap node (the one with the
most recent version of the database).

This is a fairly normal message that is logged until all nodes have 
been probed by the resource agent.

If you keep seeing this message, that probably means one of the node
cannot be probed by the resource agent. If so, crm_mon -A -1 may tell 
you which one.
