Also if it is software raid, when you make the XFS filesyste, on it,
it sets up a proper (and tuned) sunit/swidth, so why would you want
to change that?

Oh I didn't, the sunit and swidth were set automatically. Do they look
sane?. From reading the XFS section of the mount man page, I'm not
entirely sure what they specify and certainly wouldn't have any idea
what to set them to.

You should not need to set them as mount options unless you are overriding 
the defaults.
