[Pacemaker] Master won't get promoted

Hi,

I'm making some headway finally with my pacemaker install but now that
crm_mon doesn't return errors any more and crm_verify is clear, I'm having a
problem where my master won't get promoted.  Not sure what to do with this
one, any suggestions?   Here's the log snippet and config files:

My drbd config file:

}

corosync.conf:
