With this, if you want to use it JBOD, don't you have to create fake RAID
volumes on each drive. Initially this is
Drive0 Volume0
Drive1 Volume1
etc. Does FreeBSD use the Volume numbers at all when assigning drive IDs
/dev/da0
/dev/da1
....
/dev/daN
or does it work purely from the slot position?
Many Thanks - Damian
