CentOS - Jul 2012 - [Clustering] No OCFS2 Clusters with Pacemaker/Corosync?

Hello Fellow CentOS users. 

I was hoping to get some information on Pacemaker clusters using OCFS2 on CentOS
6.x. In my initial attempts to get this to work, I realized that Pacemaker is
packaged much differently on CentOS than it is on Debian or SUSE. For example,
/usr/sbin/dlm_controld.pcmk is missing and ocfs2-tools is nowhere to be found.
Users could of course pull in packages from say Oracle Enterprise Linux, but I
was curious as to why this is the case? Is OCFS2 not supported on CentOS?

Thanks for the insight.
