Couldn't find any PingAck's in the syslog - what else could have caused the split brain?
I posted the results of the log file search here: http://pastie.org/3400863 DRBD replication is running over dedicated NIC's via a switch which runs the internal subnet for the web and database servers. I don't have any fencing in place...."FLAME!" but am looking into it right now. All I can say is I'm really happy this happened now - the site is scheduled to go live in a few hours. I reconfigured the load balancer not to route any incoming requests to the secondary node until this is sorted.
