拾遗：『ext4 Quota』

一、关闭selinux

[root@6 home]# sestatus -v
SELinux status:                 disabled
示例：临时关闭
[root@6 home]# setenforce 0
示例：永久关闭
[root@6 home]# vi /etc/selinux/config
SELINUX=disabled

二、在/etc/fstab中添加usrquota、grpquota挂载参数

/dev/mapper/VolGroup-lv_home /home   ext4   defaults,usrquota,grpquota  1 2

三、使用quotacheck扫描创建配置文件

# quotacheck －avug

四、使用edquota编辑配置文件

编辑指定用户／组的配额
# edquota -u username／-g groupname
更改超额宽限期
# edquota -t

五、开启／关闭quota

全部开启／关闭
# quotaon/quotaoff -avug
指定user／group关闭
# quotaon/quotaoff -u USERNAME/-g GROUPNAME

六、查看配额报告／状态

[root@6 home]# repquota -avugs
