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.

So it should be, gluster volume add-brick test-pfs-ro1 jc1letgfs7:/export/read-only/g01 jc1letgfs8:/export/read-only/g01 jc1letgfs7:/export/read-only/g02 jc1letgfs8:/export/read-only/g02 - Anush DISCLAIMER: This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
