	I don't have. My fstab is :

dk1 is an iSCSI target. dk0 is a raid5 volume.

legendre# raidctl -s raid0
Components:
           /dev/wd2a: optimal
           /dev/wd3a: optimal
...
legendre# raidctl -s raid1
Components:
           /dev/wd4e: optimal
           /dev/wd5e: optimal
           /dev/wd6e: optimal

	I haven't found any direct usage of USB in bacula.
