Sometimes it is just udev or equivalent doing a race.
Sometimes it is a unix domain socket or similar still held open
(won't necessary show up in lsof/fuser).
Sometimes it is some device mapper targets not yet taken down.
Sometimes it is nfs locks not being properly released (in time).

What do you use DRBD for, what sits on top of it?
