I myself do not use RAID, so I may be totally wrong, but I pretty sure
that you have to create a new initramfs image.

Note that, the arch installer automatically generates the image after
the configuration is done (the penultimate step of the installer -
"Configure System"). I guess that's why it is not explicitly mentioned
in the wiki.

If you edit your mkinitcpio.conf *without* or *after* running this
step, then you have to create a new image on your own. Otherwise, the
installer takes care of it.

Again, I do not use RAID, but given your problems and the lack of
results from the solutions mentioned above, I think this is likely
your problem.
