You can't do this. gmirror is FreeBSD specific, and other OSes can't
deal with it. You can take your two drives, partition them (fdisk) and
then create a gmirror across the slices you assign to FreeBSD. Similarly
you could set up md to mirror the slice(s) used for Linux. As far as I
know, Windows doesn't come with OS level mirroring software -- it can use
hostraid[*], or I believe there are some commercial solutions you can
purchase. Or just treat your Windows partitions as two separate drives,
and live without resilience for that OS.
I can correct you here. XP Pro and later do know about 'dynamic' disks
and they can make mirrors from them. Booting from such disks is a kind
pain in the ass but it works for RAID0, RAID1, RAID0+1 and RAID5 setup.
I can be wrong, I'm not a Win-fan, I just do know this exists. You can
find details here:
