quota磁盘配额(user)
1.开启配额功能:
[root@localhost /]# mount -o usrquota /dev/sda5 /mnt/
2.设置用户配额:
[root@localhost /]# edquota -u robin /mnt

3.查询配额的使用情况
[root@localhost /]# repquota -u /mnt
4.启动配额:
[root@localhost mnt]# quotaon /mnt/
测试:
测试空间配额
su - robin
dd if=/dev/zero of=/mnt/data bs=120M count=1 dd: 写入"/mnt/data" 出错: 超出磁盘限额 测试文件个数配额
touch /mnt/abc{1..25}.txt
group配额:
group upup
useradd -g upup king
useradd -g upup zorro 1.开启组配额
[root@localhost /]# mount -o grpquota /dev/sda5 /mnt/
2.配置组配额
[root@localhost /]# edquota -g upup
Disk quotas for group upup (gid 1002):
Filesystem                   blocks       soft       hard     inodes     soft     hard
/dev/sda5                         0      51200     102400          0       10       20 3.查询配额的使用情况
[root@localhost /]# repquota -g /mnt
4.激活组配额
[root@localhost /]# quotaon -g /mnt/ 测试:
[root@localhost ~]# su - king
[king@localhost mnt]$ dd if=/dev/zero of=/mnt/data1 bs=80M count=1 [root@localhost ~]# su - zorro
[zorro@localhost ~]$ dd if=/dev/zero of=/mnt/data2 bs=80M count=1 测试配额空间为共用
设置宽限时间
[root@localhost ~]# edquota -t
Grace period before enforcing soft limits for users:
Time units may be: days, hours, minutes, or seconds
Filesystem             Block grace period     Inode grace period
/dev/sda5                     30seconds                  7days
测试:
1.开启配额功能:
[root@localhost /]# mount -o usrquota /dev/sda5 /mnt/
2.设置用户配额:
[root@localhost /]# edquota -u robin /mnt
Disk quotas for user robin (uid 1000):
Filesystem                   blocks       soft       hard     inodes     soft     hard
/dev/sda5                         0          50M         100M         0        10        20
3.查询配额的使用情况
[root@localhost /]# repquota -u /mnt
4.启动配额:
[root@localhost mnt]# quotaon /mnt/
