RHEL5 quota测试

RHEL5 quota测试
1.编辑/etc/fstab使分区挂载的时候支持quota
LABEL=/home              /home                    ext3     usrquota,grpquota,defaults         1 2
2.扫瞄磁盘的使用者使用状况，并产生重要的 aquota.group 与 aquota.user
[root@redhat home]# quotacheck -ug /home
[root@redhat home]# ls -l
total 112
    -rw------- 1 root       root        7168 Nov 11 10:09 aquota.group
-rw------- 1 root       root        7168 Nov 11 10:09 aquota.user
3.添加用户quotatest来进行quota测试
[root@redhat home]# useradd quotatest
4.edquota -u quotatest
Disk quotas for user quotatest (uid 504):
Filesystem                    blocks        soft        hard      inodes      soft      hard
/dev/sda8                         0          20000        20000           8         0         0
简单说明：红色那一组才是限制磁盘使用空间大小的，blocks不用管，默认0；soft和hard这下面两个值的单位是kb.
5.启用quota
[root@redhat home]# quotaon -a

6.测试
[quotatest@redhat ~]$ quota -vu
      Disk quotas for user quotatest (uid 504):
      Filesystem blocks    quota    limit    grace    files    quota    limit    grace
       /dev/sda8       40    20000    30000                5        0        0
[quotatest@redhat ~]$ dd if=/dev/zero of=test.db1 bs=1024k count=12
      12+0 records in
      12+0 records out
      12582912 bytes (13 MB) copied, 0.0510098 seconds, 247 MB/s
    [quotatest@redhat ~]$ quota -vu
      Disk quotas for user quotatest (uid 504):
      Filesystem blocks    quota    limit    grace    files    quota    limit    grace
       /dev/sda8    12348    20000    30000                6        0        0
[quotatest@redhat ~]$ dd if=/dev/zero of=test.db2 bs=1024k count=12
      sda8: warning, user block quota exceeded.
      12+0 records in
      12+0 records out
      12582912 bytes (13 MB) copied, 0.0429055 seconds, 293 MB/s
    [quotatest@redhat ~]$ quota -vu
      Disk quotas for user quotatest (uid 504):
      Filesystem blocks    quota    limit    grace    files    quota    limit    grace
       /dev/sda8    24656* 20000    30000    7days        7        0        0
[quotatest@redhat ~]$ dd if=/dev/zero of=test.db3 bs=1024k count=12
      sda8: write failed, user block limit reached.
      dd: writing `test.db3': Disk quota exceeded
      6+0 records in
      5+0 records out
      5455872 bytes (5.5 MB) copied, 0.0195092 seconds, 280 MB/s
[quotatest@redhat ~]$ quota -vu
      Disk quotas for user quotatest (uid 504):
      Filesystem blocks    quota    limit    grace    files    quota    limit    grace
       /dev/sda8    30000* 20000    30000                8        0        0
[quotatest@redhat ~]$

附加：如果需要对大量用户进行相同的quota操作，可以使用以一命令进行quota复制
     [root@redhat home]# edquota -p quotatest newuser
