Nope. :)

I use DRBD Primary/Primary extensively in RHCS. What I do is add it as a
script resource along with clvmd and gfs2. Then I create two failover
domains, one for each node, that is restricted and contains only that
node. Then for each failover domain, I create a service tree that
starts, in order, drbd -> clvmd -> gfs2.

Then you can create normal services, failover groups and whatnot.
