使用samba挂载后的目录 chown不启作用？

比如：

查看挂载

df -hT
Filesystem Type Size Used Avail Use% Mounted on
//ip/scandata cifs 985G 51G 935G 6% /opt/scandata

执行chown 改变属主

sudo chown -R app:app /opt/scandata/

但查看还是root

[x@5onf]$    ls -lah /opt/scandata
total 0
drwxr-xr-x 2 root root 0 Jan 24 16:57 .
drwxr-xr-x. 8 root root 120 Jan 25 17:36 ..
drwxr-xr-x 2 root root 0 Jan 24 15:48 lost+found
drwxr-xr-x 2 root root 0 Jan 24 17:55 test
-rwxr-xr-x 1 root root 0 Jan 24 16:42 test.txt

这里需要挂载的时候就指定uid 和gid，这样挂载后就是属于app:app了

比如挂载：

sudo mount -t cifs  //ip地址/scandata /opt/scandata -o uid=(指定挂载后目录的属主),gid=(指定挂载后目录的组),username=,password=

在fstab里：

//ip地址/scandata      /opt/scandata               cifs     uid=,gid=,rw,suid,dev,exec,auto,nouser,async,username=,password=        0 0

现在查看：

[@1 ~]$    ls -lah /opt/scandata
total 0
drwxr-xr-x 2 app app 0 Jan 26 15:47 .
drwxr-xr-x. 11 root root 160 Jan 25 17:36 ..
drwxr-xr-x 2 app app 0 Jan 24 15:48 lost+found
drwxr-xr-x 2 app app 0 Jan 24 17:55 test
-rwxr-xr-x 1 app app 0 Jan 26 15:45 testapp.log
-rwxr-xr-x 1 app app 0 Jan 26 15:47 testserverapp.log
