Thank you for your response.

Out of curiosity, are there any documents related to the upcoming HA
translator available online ?

As for AFR on the client side - i haven't tried it, but in the time
between sending my original email and receiving your response, i read
over this (alternative) HA Gluster cluster document :
http://www.gluster.org/docs/index.php/Simple_High_Availability_Storage_with_GlusterFS_1.3

This document appears to suggest a scenario in which the fileservers
have no knowledge of each other, and it's up to the clients to write to
each of the fileservers (via afr or afr/unify).  In this fashion, the
clients are ultimately responsible for the mirroring functionality - is
this a correct interpretation ?
