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 ~]# mdadm -Cv /dev/md5 -l5 -n3 /dev/sd[bcd]1
[root@localhost ~]# pvcreate /dev/md5
Physical volume "/dev/md5" successfully created.
root@localhost ~]# vgcreate myvg /dev/md5
Volume group "myvg" successfully created
root@localhost ~]# lvcreate -L 5G -n mylv myvg
Logical volume "mylv" created.
