That doesn't work: Error is:
Child process does not terminate!
Exiting.
No response from the DRBD driver! Is the module loaded ?
(Of course the module is loaded)

Both nodes dates are in sync with ntp.
Ok what I did now: created the meta-data completely from scratch on both
nodes (drbdadm create-md vm0[1,2]). I started drbd (/etc/init.d/drbd start).
I set each of the two nodes primary for one drbd device (drbdadm primary
-o vm0[1,2]). I expected drbd to start a full resync...
But nothing:
