[ale] RAID recovery

[Robert L. Harris]

It should replace it back as device 1, but if it doesn't it's
non-critical.  Every now and then I'll screw around with a co-worker and
re-arrange the drives in his test box.  Took him a while to catch me
doing it.

       ALONE.  I speak for                the same kind of thinking we used
       no-one else.                         when we created them."
