As far as I know, there is no way using pre 1.99.x code to prevent DRBD 
going split-brain in cases like the one you describe. 

The only way I can think of to prevent it is to have STONITH, and share 
the heartbeat line and the DRBD line over a single connection (and only 
that connection), and that is a clear SPOF.

I would gladly be proven wrong, since I'm facing the same problem
