Re: Geo-replication failed to delete from slave file partially written to master volume.

Hi Kotresh,

Thanks for looking into this issue!
I'm attaching log files from the slave node from /var/log/glusterfs/geo-replication-slaves/

[root@SC-183 log]# cp /var/log/glusterfs/geo-replication-slaves/84501a83-b07c-4768-bfaa-418b038e1a9e\:gluster%3A%2F%2F127.0.0.1%3Arem-volume-0001.gluster.log /home/vnosov/
[root@SC-183 log]# cp /var/log/glusterfs/geo-replication-slaves/slave.log /home/vnosov/
[root@SC-183 log]# cp /var/log/glusterfs/geo-replication-slaves/mbr/84501a83-b07c-4768-bfaa-418b038e1a9e\:gluster%3A%2F%2F127.0.0.1%3Arem-volume-0001.log /home/vnosov/

Best regards,

Viktor Nosov

Hi Viktor,

Please share geo-replication-slave mount logs from slave nodes.
