"Replicate" is the new name of "AFR" - i suppose that we should all 
start saying Replicate instead of AFR from now on, in order to avoid 
confusion. :)

There's an option for Replicated called "read-subvolume" which may be 
interesting to you :
http://www.gluster.org/docs/index.php/Understanding_AFR_Translator#General_options
"*  read-subvolume (default: none)
The value of this option must be the name of a subvolume. If given, all 
read operations are sent to only the specified subvolume, instead of 
being balanced across all subvolumes."

As for an "easy way", i suppose that's relative.  I'm no Gluster guru by 
any means - hopefully somebody else with a better understanding of 
large-scale implementations of Gluster can offer some advice !
