I try to make a dvice to busy:

# drbdadm secondary all
ioctl(,SET_STATE,) failed: Device or resource busy
Someone has opened the device for RW access!
Command 'drbdsetup /dev/drbd0 secondary' terminated with exit code 20
drbdsetup exited with code 20

It's not mountes, I'm sure. CentOS, v0.7.25,
Linux meta1 2.6.18-53.1.13.el5_lustre. #2 SMP Tue Mar 11 
12:57:23 CET 2008 x86_64 x86_64 x86_64 GNU/Linux .

By the way, it's a Lustre MDS.

What is the solution in this case?

Thank you,
