格式化
[root@xx xiao1]# mkfs -t ext3 /dev/sda9
挂载到xiao1
[root@xx xiao1]# mount -t ext3 -o usrquota,grpquota /dev/sda9 /xiao1
初始化磁盘配额库
[root@xx xiao1]# quotacheck -ucg /dev/sda9
查看
[root@xx xiao1]# ls /xiao1
aquota.group aquota.user lost+found
检测磁盘配额是否启动
[root@xx xiao1]# quotaon -p /xiao1
group quota on /ff (/dev/sde9) is off
user quota on /ff (/dev/sde9) is off
启动
[root@xx xiao1]# quotaon /xiao1
查看
[root@xx xiao1]# quotaon -p /xiao1
（停止的命令[root@localhost /]# quotaoff /xiao1）
group quota on /xiao1 (/dev/sda9) is on
user quota on /xiao1 (/dev/sda9) is on
设置磁盘配额
[root@xx xiao1]# edquota -u x2 /xiao1
Disk quotas for user x2 (uid 502):
Filesystem
blocks soft hard inodes soft hard
/dev/sda9
6 1000 1500 5 3 5
~
（用户x2的警告为1000字节
警用为1500字节
最大文件创建数为5 警告为3 禁用5）
测试
[root@xx xiao1]# su x2
切换到用户x2
创建文件
在五个后会提示
[x2@xx xiao1]$ touch sagasgdhsdh
sda9: write failed, user file limit reached.
touch: 无法触碰 “sagasgdhsdh”: 超出磁盘限额
完成！
修改期限（天）
[root@xx xiao1]# edquota –t
将x2的限制值复制给 账户
[root@xx xiao1]# edquota -p x2 -u x3
[root@xx xiao1]# edquota -p x2 -u x4
（x3,x4为账户）
