Unfortunately we do not have option to choose Active Workers. Following
two modes are supported(Both are automatic)
Node ID:(Default Mode)
----------------------
If a node ID present in first up sub volumes list then the respective
worker will become Active, Rest of the workers will be passive. (Note:
If multiple bricks present in same node then all worker will become
Active irrespective of replica is active)
If Active node goes down then next up node from sub volume will become
Active.
Meta Volume:
------------
Meta Volume can be used to keep lock files. All workers of a replica
group will try to acquire lock, but one worker among replica group will
get the lock and becomes active. If a Active Node/Worker goes down then
other Passive workers will get lock and become Active.
Look for Meta Volume in the following doc,
http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Distributed%20Geo%20Replication/
We are working on to provide option to choose Active workers
manually.(Hopefully this feature will land in 3.10 release(Dec 2016))

Hi folks,
I am using distributed geo replication with 3 Nodes and 1 geo redundant
node.
I want to change the Active node:
root@test1:~# gluster volume geo-replication gldata
192.168.0.104::georeplica status
MASTER NODE MASTER VOL MASTER BRICK SLAVE
USER SLAVE SLAVE NODE STATUS CRAWL
STATUS LAST_SYNCED

test2 gldata /home/glusterfs/bricks root
192.168.0.104::georeplica 192.168.0.104 Passive N/A

test3 gldata /home/glusterfs/bricks root

Any hints/commands on how to switch Active to test2?
