xfs_quota: cannot set limits: Function not implemented 解决办法

ENV：

[[email protected] ~]# uname -r
3.10.0-514.el7.x86_64
[[email protected] ~]# cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core)
[[email protected] ~]# xfs_quota -V
xfs_quota version 4.5.0
           

正在学习linux系统的quota磁盘配额，但是在操作时出现错误Function not implemented：

[[email protected] newFS]# xfs_quota -x -c 'limit bsoft=3m bhard=6m isoft=3 ihard=6 test' /mnt/newFS/  
xfs_quota: cannot set limits: Function not implemented
           

哪里出现错误了？？找了man xfs_quota 文档，其中的例子：

EXAMPLES
       Enabling quota enforcement on an XFS filesystem (restrict a user  to  a
       set amount of space).

            # mount -o uquota /dev/xvm/home /home
            # xfs_quota -x -c 'limit bsoft=500m bhard=550m tanya' /home
            # xfs_quota -x -c report /home

       Enabling project quota on an XFS filesystem (restrict files in log file
       directories to only using 1 gigabyte of space).

            # mount -o prjquota /dev/xvm/var /var
            # echo 42:/var/log >> /etc/projects
            # echo logfiles:42 >> /etc/projid
            # xfs_quota -x -c 'project -s logfiles' /var
            # xfs_quota -x -c 'limit -p bhard=1g logfiles' /var
           

和操作的一样啊，怎么会不能实现的呢？？

最后找了百度，排在前几个的老外遇到的也是一样的情况，但是看到最后也是没有得到解决，最后还是在国人的博客找到解决方法：

[[email protected] ~]# vim /etc/fstab

/dev/sdb1 /mnt/newFS xfs defaults,usrquota,grpquota 0 0  
                    //就是在这行默认配置中加上usrquota,grpquota

           

设置完后mount -a    再执行，怎么还不行呢？？？没办法，直接重启：

[[email protected] ~]# shutdown -r now
           

启动完后，再执行一次吧：

[[email protected] ~]# xfs_quota -x -c 'limit bsoft=3m bhard=6m isoft=3 ihard=6 test' /mnt/newFS
[[email protected] ~]# xfs_quota -x -c report /mnt/newFS/
User quota on /mnt/newFS (/dev/sdb1)

[[email protected] ~]# 
           

这次可以了。

在最后还要感谢下面两位的解决方法，因两个的内容一样，就都贴出来一起感谢了。
