[Pacemaker] Master/Master Setup

[Michael Marrotte]

Raoul:

I made some progress...  The default location of the relay-log and log-bin
weren't matching up.  So, when I specify them things worked out -- now
Pacemaker is starting my mysql instances and replication is working -- that
is, master/slave...  Next hurdle is master/slave <-> master/slave.

Thanks for your help.

~Mike.
