[Gluster-users] geo-replication going offline in 3.5 and 3.6 with 30 days

[Kotresh Hiremath Ravishankar]

Hi Brian,

Thanks for reporting the issue.

Could you please post the geo-replication logs?
It would help us find out why geo-replication has failed to sync.

You can find master geo-rep logs under /var/log/glusterfs/geo-replication
and slave logs under /var/log/glusterfs/geo-replication-slaves

Thanks and Regards,
Kotresh H R
