磁盘管理综合测试题

 

实验需求：

1、用户需把/dev/myvg/mylv逻辑卷以支持磁盘配额的方式挂载到网页目录下

2、在网页目录下创建测试文件index.html，内容为用户名称，通过浏览器访问测试

3、创建用户账户，对LVM配置磁盘配额限制用户磁盘容量为软限制80M；硬限制100M、文件数量软限制为80个；硬限制为100个。

 

实验拓扑：

 

 

 

实验步骤：

[root@localhost ~]# pvcreate /dev/md5

WARNING: ext4 signature detected on /dev/md5 at offset 1080. Wipe it? [y/n]: y

  Wiping ext4 signature on /dev/md5.

  Physical volume "/dev/md5" successfully created

[root@localhost ~]# vgcreate myvg /dev/md5

  Volume group "myvg" successfully created

[root@localhost ~]# lvcreate -L 40G -n mylv myvg

  Volume group "myvg" has insufficient free space (10231 extents): 10240 required.

[root@localhost ~]# lvcreate -L 39G -n mylv myvg

  Logical volume "mylv" created.
