ummmm. yeah. something else is using the underlying device. it is
mounted to /home. maybe lsof wont show the device if it is just mounted.
either way, you need to umount /home restart drbd so that drbd can claim
the device, /dev/md1. you would then want to change your fstab to point
/home to /dev/drbd1 instead of /dev/md1.

Hello Mike,
I´ve checked the slave with a lsoft | grep /home and nothing comes up,
so that means that nothing is using that partition is that right?
I have a line on the /etc/fstab that includes the /home :
/dev/md1 /home ext3 defaults 0 2
*********
Also I have tried this, I stopped the DRBD and started again (on the
slave only, the master is running) and I got this error:
Starting DRBD resources: [ d(HOME) /dev/drbd1: Failure: (114) Lower
device is already claimed. This usually means it is mounted.
[HOME] cmd /sbin/drbdsetup /dev/drbd1 disk /dev/md1 /dev/sdc3 0
--set-defaults --create-device --on-io-error=detach failed - continuing!

Any Idea?
Thanks a lot for your response!

Why does one resource comes up in diskless mode, does it mean that its
faulty?
iirc, it means that either it isn't configured with a disk or that
drbd could not open the device it is configured for. i think it wont
use a disk if it is mounted or otherwise in use. so check to see if
the disk is used by anything else. lsof can help identify what is.
