I have my RAID 5 array working nicely now, but there's a lingering
quirk.  When I created it, I only had 2 out of 3 components online.
Then I transferred data onto it and added the third component.  Then I
did:

raidctl -a /dev/sd4e raid1
raidctl -F component2 raid1

So it added the third component (sd4e) as a spare, and it failed the
mythical component2 and did a reconstruction onto sd4e.  I also
rebuilt the parity after this, using raidctl -P.  But now I have this:

gamera# raidctl -s raid1
Components:
           /dev/sd2e: optimal
           /dev/sd3e: optimal
          component2: spared
Spares:
           /dev/sd4e: used_spare


How do I get sd4e to be a component, rather than a spare?

The last time I rebooted, it came up again in degraded mode, with
component2.  So I had to re-do the reconstruction.

This array is in auto-configure mode, also; does that have something
to do with the trouble here?  It almost sounds like I need to:

raidctl -A no raid1
edit /etc/raid1.conf
raidctl -u raid1
raidctl -c /etc/raid1.conf raid1
raidctl -A yes raid1

Is that right?  (Actually, raid1.conf already has the right data in
it, so I shouldn't have to edit anything.  Here's the contents of the
file:)

Thanks in advance for any help.
