Hence, the aftermath on a properly booted system:
pearl# atacontrol status 1
ar1: ATA RAID1 subdisks: ad4 ad6 status: READY
pearl# atacontrol status 0
ar0: ATA RAID1 subdisks: ad2 ad0 status: READY
pearl# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/ar1s1a 246M 185M 41M 82% /
/dev/ar1s1g 38G 9.7G 26G 27% /home
/dev/ar1s1e 38G 3.3G 32G 9% /usr
/dev/ar1s1f 29G 7.9G 19G 30% /var
procfs 4.0K 4.0K 0B 100% /proc
I must add that atacontrol is such a much simpler RAID manipulation tool
than vinum. I haven't done any redundancy checks or anything as of yet,
but it almost seems too good to be in the base system :)
