working directory: /usr/local/mfs/var/mfs
lockfile created and locked

hdd space manager: can't create lock file '/mnt/sdb1/.lock': EACCES (Permission denied)
hdd space manager: no hdd space defined in /usr/local/mfs/etc/mfs/mfshdd.cfg file

# 硬盘空间管理器：不能创建锁文件 /mnt/sdb1 (权限拒绝)
# hdd空间管理器：没有在/usr/local/mfs/etc/mfs/mfshdd.cfg文件中定义的hdd空间
# init：硬盘空间管理器失败

解决办法：

# 检查配置文件
[root@011 ~]# cat /usr/local/mfs/etc/mfs/mfshdd.cfg
/mnt/sdb1
# 查看挂载点目录的文件用户和属组
[root@011 ~]# ls -ld /mnt/sdb1/
drwxr-xr-x 3 root root 4096 Sep 11 18:08 /mnt/sdb1/

# 将该目录的归属设为mfs用户和组
[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/
