I know I am not providing a solution for your problem but when one of the nodes in the 2 ocfs2 cluster crashed, the 2nd would crash or freeze all I/O activity on the OCFS2 filesystems for a couple of minutes.
that behavior went away when I put them under Heartbeat control (I's stuck with SLES 10), oh! ocfs2 filesystems won't mount on a cluster, until you provide a stonith config. best regards, enrique.
