In addition to what Robert said, you'll need to pull various patches
from the SUSE kernel tree to make this work - otherwise OCFS2 won't
accept the membership events from user-space (heartbeat).

The ocfs2-* patch series is probably all required, or simply use SLES10
directly as your base and all will be well ;-)

(We're still working with Oracle to merge them upstream.)
