quota+samba实现共享配额

一、检查quota是否安装：

[[email protected] ~]# rpm -qa | grep quota

quota-3.13-1.2.5.el5

二、检查、配置磁盘挂载选项

1.配置quota前

[[email protected] ~]# cat /etc/fstab |grep sdc

UUID="d6c99ad6-0c55-46e8-b9ac-68e19c3c3c12"  /sdc  ext2 defaults        1 1

[[email protected] ~]#  mount |grep /dev/sdc

/dev/sdc on /sdc type ext2 (rw)

2.修改quota配置

[[email protected] ~]# cat /etc/fstab |grep sdc

UUID="d6c99ad6-0c55-46e8-b9ac-68e19c3c3c12"  /sdc  ext2 defaults,usrquota,grpquota       1 1

[[email protected] ~]# umount /dev/sdc

[[email protected] ~]# mount -a (无报错即可成功挂载。)

[[email protected] ~]# mount |grep /sdc

/dev/sdc on /sdc type ext2 (rw,usrquota,grpquota)

三、创建用户、组，配置磁盘限额

1.创建用户、组

[[email protected] ~]# groupadd share

[[email protected] ~]# useradd user1 -g share

2.创建配额文件

[[email protected] sdc]# quotacheck -cumg /sdc

[[email protected] sdc]# ls

aquota.group  aquota.user  lost+found

3.创建用户配额

shell命令创建

[[email protected] sdc]# setquota -u user1  102400  102400  0  0  /sdc

软限制容量50M，硬限制100M，限制300个文件、目录，

edquota创建（类似vi）

[[email protected] sdc]# edquota -u user1

Disk quotas for user user1 (uid 500):

Filesystem                   blocks       soft       hard     inodes     soft     hard

/dev/sdc                          0       102400      102400          0      300      500

4.开启配额

[[email protected] sdc]# quotaon -avug

/dev/sdc [/sdc]: group quotas turned on

/dev/sdc [/sdc]: user quotas turned on

四、smb配置

[[email protected] samba]# tail smb.conf

;       writable = yes

;       printable = no

;       write list = +staff

[sdc]

comment = sdc

path = /sdc/share

public = no

writable = yes

guest ok = no

valid users = user1

五、验证

①在windows上映射磁盘，显示分区为100M

②在Linux上挂载，显示为共享磁盘的原始容量。

但是测试往磁盘写200M数据，只能成功写入100M。
