Re: Geo-replication stops after 4-5 hours

On both active master nodes there is an rsync process. As in:

root      5921  0.0  0.0 115424  1176 ?        S    Aug01   0:00 rsync -aR0 --inplace --files-from=- --super --stats --numeric-ids --no-implied-dirs --xattrs --acls . -e ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no -i /var/lib/glusterd/geo-replication/secret.pem -p 22 -oControlMaster=auto -S /tmp/gsyncd-aux-ssh-stuphs/bf60c68f1a195dad59573a8dbaa309f2.sock geouser@urd-gds-geo-001:/proc/13077/cwd

There is also ssh tunnels to slave nodes and  gsyncd.py processes.

Could you look of any rsync processes hung in master or slave?

All nodes run CentOS 7, updated the last couple of days.

Thanks

Hi all!

I upgraded from 3.12.9 to 4.1.1 and had problems with geo-replication.

With help from the list with some sym links and so on (handled in another thread)

I got the geo-replication running.

It ran for 4-5 hours and then stopped, I stopped and started geo-replication and it ran for another 4-5 hours.

4.1.2 was released and I updated, hoping this would solve the problem.

I still have the same problem, at start it runs for 4-5 hours and then it stops.

After that nothing happens, I have waited for days but still nothing happens.


I have looked through logs but can not find anything obvious.


Status for geo-replication is active for the two same nodes all the time:
