[ovirt-users] Gluster Geo-Replication Fails

Hi All, I have to sites each with 2 x 3 Node clusters. oVirt 4.4.5 with GlusterFS 8.4. On Site A I have a Replica 3 + Arbiter volume that I want to geo-replicate to Site B. I've setup a Replica 3 + Arbiter volume on Site B. All password-less ssh requirements are in place and the Geo-Replication Session has been created successfully. I issue the 'Start' command successfully but the status switches between 'Initializing', 'Active' & 'Failed' within 20 seconds constantly. Can anyone point me in the direction to get this up and running as it is our proposed DR solution. Kind Regards Shimme
