Please advise. Thank you very much. Joe
* "the" heartbeat cable == one heartbeat cable? Not supported setup -- use at least two heartbeat channels, add at least the DRBD replication network. * you produced a split brain situation. I'd expect you see errors in your cluster status and see DRBD log entries with a wording similar to "not allowed to become primary because allow-two-primaries is not set" ... if you had also pulled DRBD link you would have all resources running twice * use stonith to recover from a split-brain situation (or block if its unsuccessful) * read more manuals ;-) > > *CENTOS 5.6/drbd8.3/corosync/pacemaker > > node-0 IP: 192.168.1.101 (heartbeat) 10.0.0.10 (drdb) > node-1 IP: 192.168.1.102 (heartbeat) 10.0.0.20 ( drbd) > Cluster Virtual IP: 192.168.1.160 > > * _crm configure show_ > node $id="2b68511d-b96f-4b56-9f66-70262e3e2c46" mysqldrbd01 \ > attributes standby="off" > node $id="d86dc58b-2309-43d9-af96-6519127e83d7" mysqldrbd02 \ > attributes standby="off" These ids are from Heartbeat CCM ... but you attached a Corosync configuration? Decide for one ... either Heartbeat or Corosync.
