[root@011 ~]# cat /usr/local/mfs/etc/mfs/mfshdd.cfg
/mnt/sdb1
# 檢視挂載點目錄的檔案使用者和屬組
[root@011 ~]# ls -ld /mnt/sdb1/
drwxr-xr-x 3 root root 4096 Sep 11 18:08 /mnt/sdb1/

# 将該目錄的歸屬設為mfs使用者群組
[root@011 ~]# chown -R mfs.mfs /mnt/sdb1/
[root@011 ~]# ls -ld /mnt/sdb1/
drwxr-xr-x 3 mfs mfs 4096 Sep 11 18:08 /mnt/sdb1/
