[DRBD-user] can't make node secondary

[J]

I've googled this quite a bit with no real answers to be found.
I have a drbd resource that I can't release. The file system on the 
resource is unmounted. What gives?

# drbdadm secondary rsrvr

0: State change failed: (-12) Device is held open by someone

Command 'drbdsetup 0 secondary' terminated with exit code 11



# dmesg | tail -n20
