Yep, it definitely should. Guess I'll write a patch to catch some of the
possible setup errors (mirror with 1 disk, raid4/5 with two disks (?), any
others?).
Why you shouln't do it: raidhotadd doesn't change the number of raid-disks
the mirror has. So (ignoring the fact that the process crashes) a 2nd disk
wouldn't be used as a 2nd mirror - it would just sit there as a spare. Alle
the raid disks are available and running (one out of one).
I had thought about changing this, only it can't be readily adapted to
raid5 - changing the number of raid-disks would change the size of the
filesystem. That's why I came up with the "failed-disk" idea. You specify
how many disks you actually want right at creation time, only you don't use
one of them.
