Not sure if you noticed in my previous message that I did physically power down the primary but the standby refused to take any action.

Do you have STONITH configured? I have run into this too. The primary will not take over unless it is told somehow that the secondary is really and truly dead. If you have a real STONITH device such as IPMI, it will cause the secondary to forcibly power off the primary, providing the guarantee it needs to take over. On my test cluster where I don't have a working STONITH device yet, I use the "meatware" pseudo-device, which allows me to run a program on one node to inform it that the other node is really dead and that it is OK to take over. My old heartbeat v1 clusters used to work just fine without STONITH. DRBD split brain would occur every once in a while if both nodes lost power at the same time, but I could live with this. I wouldn't be surprised if the newer Pacemaker clusters pretty much require STONITH in order to work. Maybe someone in the know can confirm or deny this? --Greg _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems Disclaimer - September 27, 2010 This email and any files transmitted with it are confidential and intended solely for General Linux-HA mailing list.
