I started from scratch & enabled debug level logging.

[Gluster-users] Geo-Replication not detecting changes
Hi Jeremiah, I believe the bug ID is #1437244 and not #1327244.>From the geo-rep logs, the master volume is failed with "Transport Endpoint Not Connected"... [2017-03-30 07:40:57.150348] E [resource(/gv0/foo):234:errlog] Popen: command "/usr/sbin/glusterfs --aux-gfid-mount --acl --log-file=/var/log/glusterfs/geo-replication/foo/ssh%3A%2F%2Froot%4054.165.144.9%3Agluster%3A%2F%2F127.0.0.1%3Afoo.%2Fgv0%2Ffoo.gluster.log --volfile-server=localhost --volfile-id=foo --client-pid=-1 /tmp/gsyncd-aux-mount-K1j3ZD" returned with 107 .. Could you try flushing iptables on both master and slave nodes and check again? #iptables -F Thanks and Regards, Kotresh H R ----- Original Message -----> From: "Jeremiah Rothschild" <jeremiah at franz.com> > To: "Kotresh Hiremath Ravishankar" <khiremat at redhat.com> > Cc: gluster-users at gluster.org > Sent: Thursday, March 30, 2017 1:16:03 PM > Subject: Re: [Gluster-users] Geo-Replication not detecting changes > > On Thu, Mar 30, 2017 at 12:51:23AM -0400, Kotresh Hiremath Ravishankar wrote: > > Hi Jeremiah, > > Hi Kotresh!
