Heartbeat Pacemaker 3 node/ip failover

Whoever in curious to know if heartbeat with more than 2 node is possible, then I say heartbeat is not limited to 2 nodes we can join more than 2 nodes. Actually I didn't copy the same authkey for the 3rd node. All the three nodes is listing now.

I Also tried Corosync, and one of the node I couldn't get online don't know why having all config and keys same, just started doubting the reliability of the Corosync which never happend in Heartbeat. Moreover, no support for Unicast in corosysnc didn't impress much.

Thanks!
