It is a two machine cluster running drbd on a dedicated link.  We had  
a UPS fail during a power bump and the and the two machines decided  
they were no longer joined.  I saw a configuration for routing cluster  
communications over a dedicated link.  I want to do this with the drbd  
link since the write capacity of the drbd sync is less than the link  
bundle.  Basically take the switch out of the communications loop  
except for the outside traffic.

Thanks.
