Now i have a zfs raid on the rest of my drives (ad0-ad15). If i now boot with one of these removed, will zfs try to use my system disk (now beeing ad15) ? Is it necessary to label all my drives and setup zfs to use the labeled devices ? I need glabel for this right, because there is no fs on these drives.
