I can't believe that DRBD does not provide a more professional solution.
But first, let's try:
root at xen09:# dd if=/dev/zero bs=1M count=1 of=/dev/vg1/lv_drbd1_2
1+0 records in
1+0 records out
1048576 bytes (1.0 MB) copied, 0.00540221 s, 194 MB/s
root at xen09:# drbdadm create-md drbd1_2
Device '2' is configured!
Command 'drbdmeta 2 v08 /dev/vg1/lv_drbd1_2 internal create-md'
terminated with exit code 20
drbdadm create-md drbd1_2: exited with code 20
root at xen09:# drbdadm up drbd1_2

Hmm ...
