Hi,
<div>recondition:</div><div>glusterfs version is 3.7.6</div>A node:128.224.95.140
B node:128.224.162.255
brick on A node:/data/brick/gv0
brick on B node:/data/brick/gv0
reproduce steps:
1.gluster peer probe 128.224.162.255 (on A node)
2. gluster volume create gv0 replica 2 128.224.95.140:/data/brick/gv0 128.224.162.255:/data/brick/gv0 force <span style="line-height: 23.8px;"> (on A node)</span>
3.gluster volume start gv0 (on A node)
4. mount -t glusterfs 128.224.95.140:/gv0 gluster (on A node)
5.create file 11 in dir gluster (on A node)
