No need to wait, the current tip of Pacemaker 1.1 is perfectly stable
(and included for RHEL6.0).
Almost all the testing has been done for 1.1.3, I've just been busy
helping out with some other projects at Red Hat and haven't had time
to do the actual release.
To make use of CPG-based communication, remove the "service" section
for pacemaker from corosync.conf and instead run:
service pacemaker start
after starting corosync.
Once the 1.1.3 packages are out, this will be the official advice for
anyone experiencing startup/shutdown issues when using Pacemaker with
Corosync.
Calling fork() in a multi-threaded environment (corosync) is just far
too problematic.
