[Gluster-users] Geo-replication stops after 4-5 hours

Hi,
Is there a way to resolve the problem with rsync and hanging processes?
Do I need to kill all the processes and hope that it starts again or stop/start geo-replication?
If I stop/start geo-replication it will start again, I have tried it before.
Regards
Marcus

Hi Kotresh,
I get the following and then it hangs:
strace: Process 5921 attached write(2, "rsync: link_stat \"/tmp/gsyncd-au"..., 12811
When sync is running I can see rsync with geouser on the slave node.
Regards
Marcus

Cool, just check whether they are hung by any chance with following command.
#strace -f -p 5921

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

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

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

Hi Kortesh,
rsync version 3.1.2 protocol version 31
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:
MASTER NODE MASTER VOL MASTER BRICK SLAVE USER SLAVE SLAVE NODE STATUS CRAWL STATUS LAST_SYNCED ENTRY DATA META FAILURES CHECKPOINT TIME CHECKPOINT COMPLETED CHECKPOINT COMPLETION TIME
