Right, you'd have to use ocfs2 with pacemaker + cman.
the .pcmk pieces are to teach the dlm and ocfs2 daemons about
pacemaker's membership data.
You dont need them if you use cman as the daemons (including
pacemaker) already know how to get membership data from cman.

Follow the clusters from scratch document (the '1.1-plugin' version)
and just replace gfs with ocfs.
You'd probably need to rebuild the ocfs2 packages from fedora for rhel though.

As for paid support, oracle themselves might be the only option for
ocfs2 on rhel.
