Eww. Glad I don't need DRBD too. Maybe Mike M. can make us a cookbook :)

What has complicated it for me even more is that I'm doing DRBD replication of a multi-minidisk VG between sites (active/active) with 2 nodes (active/passive) at each site using DRBD's floating IP scheme rather than stacking. I have gotten it to work once or twice, but, like you, just can't get consistent enough results to actually claim I was successful. :-) If I keep it active/passive between sites and leave out the OCFS2 (and pre/coreqs) everything works beautifully. Fortunately, Middleware is giving me a pass for a while and are gonna stick with active/passive for now. But, they will come a knockin', so I do need to get active/active to work. And I've sent corosync into more loops than the Blue Angels have done since their inception! Only way to stop the process is to kill it, at which point one of the other nodes will probably start doing the same thing. Wind up just doing a reboot (a clean stop of openais will usually hang) of all of the nodes.
