Gerald,
This should work. Geo-replication is separate for regular replication. Once
you have fixed the replication by putting the new hardware in place and
performing the replace-brick operation, you will want to trigger a self heal:
http://www.gluster.com/community/documentation/index.php/Gluster_3.2:_Migrating_Volumes
http://www.gluster.com/community/documentation/index.php/Gluster_3.2:_Triggering_Self-Heal_on_Replicate
Then you will want to set up passwordless SSH from root on one of those systems,
to root at the remote Gluster system. Keep in mind that the dependencies all
have to be correct for geo-replication on both ends and that it is advisable to
have a Gluster volume at the remote end even if it only has one brick since you
can expand it later if you need. You may also want to make sure you have 3.2.3
running at both ends. You then initiate geo-replication like:
gluster volume geo-replication VOLNAME root at REMOTEHOST::REMOTEVOLNAME start
You can check the status after a few minutes and it will say OK when it is
working. If it says anything other than that, dependencies are probably the
issue. In the commercial appliances we make sure all of the dependencies are in
place. For open source you will want to check the documentation for the list.

Hi,
Will the following scenario work?
I created a 2 bricks with replication. The second brick was my personal
machine, so I removed it from the gluster. I'm now running a replica system
with a single brick (ie: no replication).
When my new hardware comes in, I'll add it as the second brick to the
replica, and patiently wait while it syncs data.
Once I have a running replica, can I add geo-replication to the mix? If so, how
would that be done?
Gerald
