[Gluster-users] Setting up a 2 sites replication with access to files from both sites

[David Coulson]

I am not aware of a mechanism where you can force a read from only one brick, but write to both, short of having reads done out of a totally separate directory structure.

Someone can correct me if this is wrong, but that is how my replica configuration behaves w/ 3.2.5.
