Hi, Xsync might work well for you as it doesn't sync deletes and renames. I see the below patch in v3.6.1 branch. Well I don't know why you are not seeing that patch in your setup. It's just a simple python file patch. It can be directly applied and use changelog as change-detector to sync deletes and renames.

Could you please provide geo-replication slave logs? 2. Steps to configure geo-replication different for glusterfs version <=3.4 and >=3.5 For gluster-geo-replication <=3.4 http://www.gluster.org/community/documentation/index.php/HowTo:geo-replication For gluster-geo-replication >=3.5 https://github.com/gluster/glusterfs/blob/master/doc/admin-guide/en-US/markdown/admin_distributed_geo_rep.md Upgrade steps from gluster-geo-replication-3.4 to 3.5 http://www.gluster.org/community/documentation/index.php/Upgrade_to_3.5 Thanks and Regards, Kotresh H R ----- Original Message ----- From: "Gong XiaoHui" <xhgong@xxxxxxxxxxx> To: "gluster-devel@xxxxxxxxxxx" <gluster-devel@xxxxxxxxxxx> Sent: Monday, December 8, 2014 11:15:59 AM Subject: some issues about geo-replication and gfapi Hi I have two questions with glusterfs: 1.When I use libgfapi to write a file to a volume, which is configured as a geo-replication masterVol. It cannot work well, the geo status is faulty, following is the log: The glusterfs version is 3.6.1 [2014-12-08 13:12:11.708616] I [master(/data_xfs/geo2-master):1330:crawl] _GMaster: finished hybrid crawl syncing, stime: (1418010314, 0) [2014-12-08 13:12:11.709706] I [master(/data_xfs/geo2-master):480:crawlwrap] _GMaster: primary master with volume id d220647c-5730-4cef-a89b-932470c914d2 ...
