Looks to be working fine like that.   I did some testing and found that 
I should figure out something with the mail queue.  If there is a 
network failure, notification gets attempted, fails to connect to the 
mail gateway, then put into the queue.  When the secondary comes up, 
because it's picking up where the other node failed, it thinks it 
already sent the notifications.  This could easily be fixed with making 
the queue a drbd8 partition I suppose.
