normally if a disk fails in a truly redundant RAID setup (hint, RAID 0
is not actually redundant), you replace with a similar disk and rebuild,
which in RAID 1 is simply copying the data from the good (old) drive
to the good (new) drive. i've never done the procedure for Linux
software raid, i've only done this stuff with a couple of different
commercial hardware RAID controllers, where the rebuild is frequently
automagic.
