What does your disklabel look like for rz0 and rz1?  In particular, have you 
left room on the disks for their disklabels?  (i.e. rz0d and rz1d should not
start at the beginning of the disks.)  (This may not be directly related, but 
it's still useful info..)

What does your disklabel for ccd0 look like?  I'm guessing you don't have one, 
and that perhaps why newfs is upset.  (pmax seems to get a bit more upset
about this..)
