With recent DRBD versions that is supposed to "just work" ;-)

Make sure though that you don't change network parameters in drbd.conf
while Connected Primary/Primary, as that would still first disconnect
(causing split brain) then connect (detecting the split brain)...

always best to first do
 drbdadm -d adjust
to see what it would do,
before actually doing it.
