I ran into that "Device is held open by someone" with DRBD
master/master a lot. I believe it was a drbd bug. Once the system
started reported that message there was NOTHING I was able to do other
then reboot. This includes..Running all userspace "stop" like commands
--- removing module (would not let me).
It could be as simple as some process is still running inside the DRBD
folder and the system can not unmount or it could be a bug. Try all
forms of unmount/ stopping drbd.
