That's right - RAIDZ (and mirroring) only use the space of the smallest
disk in the group, so they should normally be all the same size. As with
other uses of `zpool attach` (to mirrors), the new drive needs to be no
smaller than the existing disks.

Nice. Is it the case that added drives must be the same -- or no smaller than
-- existing drives in the RAID-Z group? The documentarian in me would call
that out explicitly.

will be available in the OpenZFS 2.3 release, which is probably about a year
out.
