I'm curious to understand if there is any kind of support for Pacemaker/Corosync Clusters on RHEL 6.x (and comparable clones)  with OCFS2 as the cluster FS? 
Aside from missing a couple of rpm (e.g. ocfs2-tools to name a few), Pacemaker just seems packaged differently. For example, dlm_controld.pcmk is no where to be found. But dlm_controld does ship with cman. 
Any thoughts?
