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 ?
