We are revisiting geo-replication on some Centos7 systems running 3.8 so
I am not sure this observation will help with something newer.
But we were getting burned by the systems connect locally using ::1 as
the localhost as opposed to 127.0.0.1.
This was caused by the hosts file having an IPv6 localhost line.

While creating the Geo-replication session it mounts the secondary
Volume to see the available size. To mount the secondary volume in
Primary, port 24007 and 49152-49664 of the secondary volume needs to
be accessible from the Primary (Only in the node from where the
Geo-rep create command is executed). This need to be changed to use
SSH(bug). Alternatively use georep setup tool from
https://github.com/aravindavk/gluster-georep-tools. This tool only
uses Port 22 of SSH.
Once the Geo-rep session is created, all the communication and the
data transfer happens via SSH(Default port: 22).

Hi All,
What are the ports needed to be opened for Gluster Geo replication
? We have a very closed setup, I could gather below info, does all
of these ports need to be open on master and slave for inter
communication or just 22 would work since it's using the rsync
over ssh for actual data push ?
*•**Port 22 (TCP):* Used by SSH for secure data communication in
Geo-replication.
*•**Port 24007 (TCP):* Used by the Gluster daemon (glusterd) for
management and to intercommunicate with other glusterd instances.
*•**Ports 24008 & 24009 (TCP):* Used for GlusterFS data and
metadata operations.
*•**Port 49152 to 49664 (TCP):* Used by GlusterFS for client
connections.
I see some monitoring happening on the tcp ports for slave volume,
is this communication secure ?
