When I type in "/etc/init.d/drbd stop" it says: 
Stopping all DRBD resources/dev/drbd0: State change failed: (-12) Device is held open by someone
Command '/sbin/drbdsetup /dev/drbd0 down' terminated with exit code 11
command exited with code 11
ERROR: Module drbd is in use

I want to see the reaction of the servers, when for example the power supply of the primary server isn't there anymore.
When the power supply is up again, and server1 comes up, it should be primary/secondary again automatically, or shouldn't it?
