[ale] Hot Spares

I am reading through the software raid man pages/HOWTO, and wondered if
you can add hotspare to an MD device on the fly? I have the following in
my raidtab:

raiddev             /dev/md0
raid-level                  1
nr-raid-disks               2
persistent-superblock       1
nr-spare-disks              1
   device          /dev/hda1
   raid-disk           0
   device          /dev/hdc1
   raid-disk           1
   device          /dev/hde1
   spare-disk          0

It looks like "raidhotadd /dev/md0 /dev/hde1" should work, but I don't
have a test system handy at the moment.

Thanks,
