I actually did that myself, but I wouldn't recommend that way unless you are familiar with all that. You may search through archives and look at Andrew's blog (blog.clusterlabs.org, notably http://blog.clusterlabs.org/blog/2012/pacemaker-and-cluster-filesystems/) for additional details. You may also look at my slides at http://lvee.org/uploads/image_upload/file/267/Linux_Clusters_at_LVEE_2013.pdf In short - that is really complicated to backport everything to RHEL6.
