Could be a network thing maybe. Here's some things to try: Can you ssh or ping one node from the other? Bring up one node with the VIP running - leave the other node up but heartbeat down. an you ping the VIP from the node NOT running HA? What happens when you look at the cluster when both nodes are running - use the crm_mon command and paste what you see in here.
I'm thinking you have some sort of network issue. _______________________________________________ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
