I used HA Linux some years ago and was never happy with it, so I 
switched to RHCS. Building and maintaining clusters in it is, I find, 
much better. Now with that said, I've not gone back since Pacemaker was 
introduced, and I know a lot of people love Pacemaker now. I do plan to 
try it again before too long.

In general though, Radu said, RHCS has a central configuration in 
/etc/cluster/cluster.conf. I *love* that. With that though comes 
limitations. If you want fairly simple fail-over and recovery options, 
rgmanager is great. If you want very complex configurations though, 
Pacemaker is more flexible and.

In my mind, Pacemaker and RHCS are equally good, just different. Both 
use corosync and that's where all the magic happens.
