As you might perhaps be aware, AFR translator currently uses the client
translator names as the name of it's changelog extended attributes.
i)This can be a problem when a remove-brick operation is performed when
there are pending heals happening because remove-brick causes a graph
change wherein the client translator names become different.
ii) Also, for gluster snapshot volumes to work correctly, there needs to
be a persistent mapping of AFR changelog attributes to the bricks.
After some internal discussions, we have come up with a new naming
mechanism that ensures backward compatibility. Details on the
aforementioned problems and the proposed solution are detailed in a
feature page  for GlusterFS 3.6.
Please feel free to go through it and give your comments/ critiques.
Thanks and regards,
