Hi!

Just food for thought, but have you tested gracefully shutting down one
of your nodes and then bringing it back up?  That is, at least putting a
node into standby and then taking it back out, or better yet
node-standby -> stop all cluster resources on node -> reboot -> start
cluster resources -> node-online?  This was were I ran into problems
with OCFS2's various mechanisms not being properly configured/used.
