[Gluster-users] Unable to setup geo replication

Tue Nov 26 07:42:59 UTC 2019

Rsync on both the slave and master are rsync  version 3.1.3  protocol version 31, so both are up to date as far as I know.
Gluster version on both machines are glusterfs 5.10
OS on both machines are Fedora 29 Server Edition

The error code 14 related IPC where any of pipe/fork fails in rsync code.
Please upgrade the rsync if not done. Also check the rsync versions between master and slave to be same.
Which version of gluster are you using?
What's the host OS?
What's the rsync version ?

I’m new to GlusterFS and trying to setup geo-replication with a master volume being mirrored to a slave volume on another machine. However I just can’t seem to get it to work after starting the geo replication volume with the logs showing it failing rsync with error code 14. I can’t seem to find any info about this online so any help would be much appreciated.
