Thanks for the quick response, but if you look at the end of my message you will see that I already tried that and the mirroring did not appear to work (see my link to my earlier thread in that same message).
Still looking for a working answer to either this question or the linked one.

You needn't specify replica there for add-brick. So it should be,
gluster volume add-brick test-pfs-ro1
