I've been trying a few things out, it seems for geo-replication you need
a third node. Or am I overlooking something?
I would like to try to setup a A->B geo-replication setup. One node
being replicated by a slave node.
But if I try to create a replicated volume, glusterfs insists on at
least two bricks.
Or should I try creating a distributed gluster volume with just one brick?
