Not yet. But it looks like the pacemaker init script was also kicked off somehow (otherwise the crmd etc would not be running)

Would it be possible for you to add:

export PCMK_trace_functions=peer_update_callback 

to /etc/sysconfig/pacemaker and re-test (and send me the new logs - probably in /var/log/pacemaker.log)?
