Linux基本功杂记——[020]——『ext4 Quota』

一、关闭selinux

[root@6 home]# sestatus -vSELinux 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/configSELINUX=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*** Report for user quotas on device /dev/mapper/VolGroup-lv_homeBlock grace time: 7days; Inode grace time: 7days                        Block limits                File limitsUser            used    soft    hard  grace    used  soft  hard  grace----------------------------------------------------------------------root      --      20       0       0              2     0     0       test      --      16       0       0              4     0     0       Statistics:Total blocks: 7Data blocks: 1Entries: 2Used average: 2.000000*** Report for group quotas on device /dev/mapper/VolGroup-lv_homeBlock grace time: 7days; Inode grace time: 7days                        Block limits                File limitsGroup           used    soft    hard  grace    used  soft  hard  grace----------------------------------------------------------------------root      --      20       0       0              2     0     0       test      --      16       0       0              4     0     0       Statistics:Total blocks: 7Data blocks: 1Entries: 2Used average: 2.000000
