Mm, weird. I origionally tried the raidctl on the c0t8d0 to mirror c0t9d0, but that failed with the "Disks must be different".
I then was able to make a mirror of the OS disk using ufsdump to c2t0d0. When booted to c0t9d0, I then ran:
raidctl -c c2t0d0 c2t1d0
and that worked, I then booted to that disk, c2t0d0, and now I'm using raidctl.
Pretty weird.
