[Pacemaker] pacemaker + rhel6 and clvmd

[David Coulson]

Are you running 'real' RHEL6?

If so, cman + clvmd + gfs2 is the way to go. You can run pacemaker on 
top of all of that (without openais) to manage your resources if you 
don't want to use rgmanager.

I've never tried to run clvmd out of pacemaker, but there is a init.d 
script for it in RHEL6, so that might 'just work'.
