一：内核中支持QUOTA:
[root@localhost /]# grep CONFIG_QUOTA /boot/config-3.10.0-123.el7.x86_64 CONFIG_QUOTA=y CONFIG_QUOTA_NETLINK_INTERFACE=y # CONFIG_QUOTA_DEBUG is not set CONFIG_QUOTA_TREE=y CONFIG_QUOTACTL=y CONFIG_QUOTACTL_COMPAT=y
如果有上列输出，则表示当前内核已经支持quota。
二：修改/etc/fstab加入QUOTA支持：
[root@localhost /]# vim /etc/fstab
/dev/sdb1 /dvd xfs defaults,usrquota,grpquota 1 2
三：使用quotacheck初始化QUOTA数据库：
因为quotacheck依据/etc/mtab搜索文件系统，所以要将刚刚修改的/dev/sdb1重新挂载
