Hi,
You are right, This tool may not be compatible with 3.6.5.
I have tried myself with 3.6.5, but faced this error.
==========================
georepsetup tv1 gfvm3 tv2
Geo-replication session will be established between tv1 and gfvm3::tv2
Root password of gfvm3 is required to complete the setup. NOTE: Password
will not be stored.
root@gfvm3's password:
[ OK] gfvm3 is Reachable(Port 22)
[ OK] SSH Connection established root@gfvm3
[ OK] Master Volume and Slave Volume are compatible (Version: 3.6.5)
[ OK] Common secret pub file present at
/var/lib/glusterd/geo-replication/common_secret.pem.pub
[ OK] common_secret.pem.pub file copied to gfvm3
[ OK] Master SSH Keys copied to all Up Slave nodes
[ OK] Updated Master SSH Keys to all Up Slave nodes authorized_keys file
[NOT OK] Failed to Establish Geo-replication Session
Command type not found while handling geo-replication options
[root@gfvm3 georepsetup]#
==========================
So, some more changes required in this tool.
Coming back to your question:
I have setup geo-replication using the commands in 3.6.5.
Please recheck all the commands (with necessary changes at your end).

====================================================================
One important step which I have NOT mentioned is you need to setup
passwordless ssh.
You need to use ssh-keygen and ssh-copy-id for having passwordless setup
from one node in Master to one node in Slave.
This needs to be carried out before this step: " gluster system::
execute gsec_create"
This needs to be done at the same NODE(at Master) where you execute
geo-rep create command.
You can find geo-replication related logs here
:/var/log/glusterfs/geo-replication/
Please share the logs if you still face any issues.
Thanks,
Saravana

Yes I can ping the slave node with it's name and IP address, I've even entered
manually its name in /etc/hosts.
Does this nice python script also work for Gluster 3.6? The blog post only
speaks about 3.7...

Hi,

Have you checked whether you are able to reach the Slave node from the
master node?
There is a super simple way of setting up geo-rep written by Aravinda.
Refer:
http://blog.gluster.org/2015/09/introducing-georepsetup-gluster-geo-replication-setup-tool-2/
Refer the README for both usual (root user based) and
mountbroker(non-root) setup details here:
https://github.com/aravindavk/georepsetup/blob/master/README.md

Hello,
I am using the following documentation in order to setup geo replication
between two sites
http://www.gluster.org/pipermail/gluster-users.old/2015-January/020080.html
Unfortunately the step:
gluster volume geo-replication myvolume gfs...@gfs1geo.domain.com::myvolume
create push-pem
Fails with the following error:
Unable to fetch slave volume details. Please check the slave cluster and slave
volume.
geo-replication command failed
Any ideas?
btw: the documentation
http://gluster.readthedocs.org/en/latest/Administrator%20Guide/Geo%20Replication/index.html
does not seem to work with GlusterFS 3.6.5 that's why I am using the other
mentioned documentation. It fails at the mountbroker step (
gluster system:: execute mountbroker opt mountbroker-root /var/mountbroker-root)
