you probably hit the bug which was fixed in 0.7.12:
* Fixed a connection flip-flop bug when the two peers used different
user provided sizes.
to verify this, first, do "drbdadm disconnect <bad_resource>".
then "drbdsetup /dev/drbdX show", as well as "cat /proc/partitions",
on both nodes. compare the results.
the solution is probably to either make sure (using some --size
parameter if possible) that your devices are of the very same size,
or upgrade to 0.7.15, which should fix the problem.
