I've been reading the documentation, but I'm a bit stumped as to how to setup geo-replication with glusterfs. The documentation mentions that you use an existing glusterfs volume to start geo replication. But what kind of volume? Do you just create a standard replicated volume with a replica count of 1? Could somebody outline the steps for geo-replication? Also, does geo-replication perform better than replication? In our setup we need redundancy, but more as a fail-safe backup option, rather than a load balancing setup. We just want to be able to quickly switch to our backup server, if our primary server should go down for any reason. Would a geo-replication setup with GlusterFS have better read and write performance, since the slave can lag behind a bit?
