[Gluster-devel] Write Only Brick at Offsite location using AFR ?

[Kevin]

Hello,

I have setup four bricks using AFR.

Bricks 1,2,3 are on the local internal network.
Brick 4 is connected into the local network using OpenVPN, but is actually at an offsite location.

Would it be possible to configure clients/server to only read from bricks 1,2,3 ?

The idea is Brick4 contains a live backup, but is on a much slower connection and uses bandwidth so I need to avoid reads if possible.

I'm currently using gluster 1.3.7.

Thanks 
Kevin
