That shouldn't be necessary.
In the latest RHEL6 packages (as well as the upstream 1.1 repo),
Pacemaker has the ability to sit on top of RHCS.

Literally the only thing that is different to the official stack is
that you use Pacemaker to configure resources and fencing.
Everything else is there and running (so clvm should also be happy).

You can either use cluster.conf for configuring corosync/cman or I can
send you the corosync.conf snippet.
