[DRBD-user] problem with more than 1 resource

[thebet at tin.it]

Hi, i have set up drbd 0.7.13.  When i try to start it i cannot start 
more than 1 resource, then i got the message:

Starting DRBD 
resources:    [ d0 d1 ioctl(,SET_DISK_CONFIG,) failed: Device or 
resource busy
cmd /sbin/drbdsetup /dev/drbd1 disk /dev/md3 /dev/md9 0 --
on-io-error=detach  failed!

Here's my drbd.conf:
