Yes, I am trying to setup geo-replication between gluster and non-gluster volumes. I really only need one-way replication for this remote for disaster recovery purposes. Any ideas why this isn't working?

It looks like there might be some configuration issue here. Please give your script of how you configured geo-replication?

I can ssh as either root or georep-user to the destination as either georep-user or root with no password using the default ssh commands given by the config command: ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no -i /etc/glusterd/geo-replication/secret.pem. All the glusterfs rpms are installed on the remote host. There are no firewalls running on any of the hosts and no firewalls in between them. The remote_gsyncd command is correct as I can copy and paste it to the command line and run it on both source hosts and destination host. I'm using the current production version of glusterfs 3.2.6, rsync 3.0.9, fuse-2.8.3 rpm's are installed, OpenSSH 5.3, and Python 2.6.6 on RHEL6.2. The remote directory is set to 777, world read-write so there are no permission errors. I'm using this command to start replication: gluster volume geo-replication RMSNFSMOUNT hptv3130:/nfs start Whenever I try to initiate geo-replication the status goes to starting for about 30 seconds, then goes to faulty.
