>Description:
When using atacontrol from single user mode, one cannot rebuild a RAID array. The command /usr/bin/nice is not mounted or available in single user mode.

# atacontrol rebuild ar0
/usr/bin/nice: not found

The raid is marked as rebuilding, but never completes. When rebooted the RAID is marked as ready:

ar0: 476937MB <Intel MatrixRAID RAID1> status: READY
ar0: disk0 READY (master) using ad4 at ata2-master
ar0: disk1 READY (mirror) using ad6 at ata3-master


However this obviously results in file system corruption:

 bad dir ino 50722 at offset 0: mangled entry
panic: ufs_dirbad: bad dir
cpuid = 1
Uptime: 25s
Cannot dump. No dump device defined.
Automatic reboot in 15 seconds - press a key on the console to abort
Rebooting...

>How-To-Repeat:
Remove one drive of an ata raid device:

# atacontrol detach ata3

Reboot into single user mode, add spare and try to rebuild:

# atacontrol addspare ar0 ad6
# atacontrol rebuild ar0


>Fix:
Move /usr/bin/nice to /bin/nice
