[arch-general] Installing to RAID .. cannot reboot

[D. R. Evans]

I have carefully followed the RAID instructions at:
  https://wiki.archlinux.org/index.php/Software_RAID_and_LVM#RAID_installation

I have not used LVM, just RAID. I have double-checked what I actually did, and
believe that I did exactly what the page tells me to do.

I have two identical drives, which I configured as RAID1.

At the conclusion of the installation, the instructions say:

----

Once it is complete you can safely reboot your machine:

# reboot

----

When I try to reboot, I receive the error message:
  ERROR: device /dev/md0 not found
  ERROR: unable to find root device /dev/md0

What do I have to do to get past this error?

  Doc

PS I tried to go back to the very beginning and walk through the instructions
again, but when I do that, when I reach this step:
  mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sd[cd]3
I am now informed that /dev/sdc3 is busy or unavailable.
