Hi Viktor,
I went through the slave logs and there are no errors w.r.t deletion of the files.
I suspect the changelog has missed recording deletion of file because of which
the delete is not processed.
Please share the following logs from master volume to root cause the issue.
1. Master geo-replication logs: /var/log/glusterfs/geo-replication/<mastervolname>/*.log
2. Master brick logs: /var/log/glusterfs/bricks/*.log
3. Also changelogs from Master volume: /exports/nas-segment-0012/master-for-183-0003/.glusterfs/changelogs/*
Thanks and Regards,
Kotresh H R
