<div>Hi John,</div>
<div>to get Corosync/Pacemaker running during anaconda installation, i have created a configuration RPM package which does a few actions before starting Corosync and Pacemaker.</div>
<div> </div>
<div>An excerpt of the post install of this RPM.</div>
<div>
<div># mount /dev/shm if not already existing, otherwise openais cannot work<br/>
if [ ! -d /dev/shm ]; then<br/>
mkdir /dev/shm<br/>
mount /dev/shm<br/>
fi</div>
<div>
<div># resource agents might run as different user<br/>
chmod -R go+rwx /var/lib/heartbeat/cores</div>
<div> </div>

Libqb tries to create some shared memory in that location by default.<br/>
