[Gluster-users] Unable to setup geo replication

Thu Nov 28 07:59:16 UTC 2019

Alright so it seems to work with some errors and this the output I’m getting.

Oh forgot about that. Just setup passwordless ssh and that particular node and try with default ssh pem key and remove /var/lib/glusterd/geo-replicationsecre.pem from the command line

I’m getting this when I run that command so something’s wrong somewhere I guess.

Ok, Then it should work.
Could you confirm rsync runs successfully when executed manually as below.

1. On master node,
     a) # mkdir /mastermnt
     b) Mount master volume on /mastermnt
     b) # echo "test data" /master/file1
2. On slave node
     a) # mkdir /slavemnt
     b) # Mount slave on /slavemnt
     c) # touch /salvemnt/file1
3. On master node
     a) # cd /mastermnt
     b) # rsync -aR0 --inplace --super --stats --numeric-ids --no-implied-dirs --existing --xattrs --acls --ignore-missing-args file1 -e 'ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no  -p 22 -oControlMaster=auto -i /var/lib/glusterd/geo-replication/secret.pem' root at pgsotc11.png.intel.com:/slavemnt/<mailto:root at pgsotc11.png.intel.com:/slavemnt/>
4. Check for content sync
     a) cat /slavemnt/file1

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.
