[Gluster-users] Understand Geo Replication of a big Gluster

[Milind Changire]

Hello Axel,
A warm welcome to you and happy to see you board the Gluster ship.

geo-replication requires two clusters: one master cluster which is the
source cluster and the second cluster called the slave cluster which is the
destination cluster

Just as you have created a primary/master cluster, you need to create
another cluster out of the backup servers in whatever configuration (volume
type) you want to create. The volume type of the slave cluster need not be
the same as the master cluster.

Once you've created the slave cluster, you can then use geo-replication
commands to create a communication channel between the two clusters so that
the sources from the master cluster are replicated to the slave cluster and
to keep pushing any updates to the slave cluster.

Hope this helps.
