The installer doesn't let you use all of the modes that mdadm can. It is
sort of a nanny to keep people from picking unusual combinations that
they may not really want.
I have asked for raid 1 to work with 1 element in anaconda several times (as
this makes adding elements later a lot easier). I think the current status
is that it will use a preexisting raid 1 array with one element (not a
2 element array with one element failed), but not allow you to create one.
