Hi Azeez,

What I suggest is that the DRBD-driver and drbdsetup should stay as
they are. I suggest that you modify drbdadm so that one can specify
multiple on sections in a resource section.

As the driver and drbdsetup are two nodes only, one will then have
to select a peer node when calling drbdadm connect. So the command
line syntax of drbdadm will have to change as well. Maybe

drbdadm --to foo-node connect r0
