Linux學習執行個體，請各位知道---對使用者的管理配額

對使用者的磁盤配額

使用虛拟機 添加一塊20G硬碟

[root@localhost ~]# fdisk -l

[root@localhost ~]# fdisk /dev/sdb （建立一個主分區sdb1,ext3）

[root@localhost ~]# partprobe /dev/sdb

[root@localhost ~]# mkfs.ext3 /dev/sdb1

[root@localhost ~]# mkdir /mail //建立挂載點

[root@localhost ~]# echo '/dev/sdb1 /mail ext3 defaults,usrquota 0 0' >> /etc/fstab //配置分區/dev/sdb1支援配額

[root@localhost ~]# mount -a // 挂載/etc/fstab 中預設的挂載項或reboot

[root@localhost ~]# mount | grep sdb1

/dev/sdb1 on /mail type ext3 (rw,usrquota)

[root@localhost ~]# ls /mail/

lost+found

[root@localhost ~]# quotacheck -uc /dev/sdb1 //生成配額檔案
