[Gluster-devel] some issues about geo-replication and gfapi

[Gong XiaoHui]

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

2.Another question, I cannot configure a geo-replication in 3.6.1 with the method in 3.4.1.
Any response is appreciate.
