I've got two-node clusters running Heartbeat (3.0.3-2.3.el5) and Pacemaker (1.0.9.1-1.15.el5) from the clusterlabs repo on CentOS 5.9 (yes, I know my Pacemaker is a little old, but I don't want to upgrade unless there is some reason to believe it will help). These clusters run Xen virtual machines that provide critical infrastructure services (such as DNS).
The problem is only that I don't know what is the best way to shut down the entire cluster cleanly (e.g. as when we do electrical maintenance in the data center and have a planned complete outage). Often one of the nodes gets stuck at "Stopping HA Services" and eventually I just have to hit the power button (physically or via IPMI). I can get a clean shutdown if I shut down one node first, then the second, but that isn't really "clean" because it causes all the virtual machines from the first node to stop and start on the second node, then go down again. I'd rather have everything just go down and stay down. Is there a recommended method for taking a cluster out of service cleanly?
