[CentOS] Corosync init-script broken on CentOS6

Hello all,

I am trying to create a corosync/pacemaker cluster using CentOS 6.0.
However, I'm having a great deal of difficulty doing so.

Corosync has a valid configuration file and an authkey has been generated.

When I run /etc/init.d/corosync I see that only corosync is started.
>From experience working with corosync/pacemaker before, I know that
this is not enough to have a functioning cluster. For some reason the
base install (with or without updates) is not starting corosync
dependencies.

I've even tried using corosync/pacemaker for the EPEL 6 repo, and
still the init-script will not start corosync dependencies.

Expected:
corosync
/usr/lib64/heartbeat/stonithd
/usr/lib64/heartbeat/cib
/usr/lib64/heartbeat/lrmd
/usr/lib64/heartbeat/attrd
/usr/lib64/heartbeat/pengine

Observed:
corosync

My install options are:
%packages
@base
@core
@ha
@nfs-file-server
@network-file-system-client
@resilient-storage
@server-platform
@server-policy
@storage-client-multipath
@system-admin-tools
pax
oddjob
sgpio
pacemaker
dlm-pcmk
screen
lsscsi
-rgmanager
%end

The logs from the server aren't terribly helpful either:

Googling suggests this is the result of mis-matched versions of
pacemaker/corosync; but this is the base install and the problem
persists even when I install it from EPEL6 repos.

Is anyone else experiencing difficulties with corosync/pacemaker on CentOS6?

Thanks,
-Hal
