Is that expected > behavior? I'd expect manually specifying expected_votes to lock it down. It's expected behavior. The quorum calculation algorithm is specifically designed to prevent what you're doing. The expected_votes is counted at startup, but grows dynamically after that. The only time where it doesn't grow is in the "two_node=1" case. -- Lon -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
