LVM几个基本概念
*物理存储介质（PhysicalStorageMedia）：指系统的物理存储设备：磁盘，如：/dev/hda、/dev/sda等，是存储系统最底层的存储单元。
*物理卷（Physical Volume，PV）：指磁盘分区或从逻辑上与磁盘分区具有同样功能的设备（如RAID），是LVM的基本存储逻辑块，但和基本的物理存储介质（如分区、磁盘等）比较，却包含有与LVM相关的管理参数。
*物理块（Physical Extent，PE）：每一个物理卷PV被划分为称为PE（Physical Extents）的基本单元，具有唯一编号的PE是可以被LVM寻址的最小单元。PE的大小是可配置的，默认为4MB。所以物理卷（PV）由大小等同的基本单元PE组成。
*卷组（Volume Group，VG）：类似于非LVM系统中的物理磁盘，其由一个或多个物理卷PV组成。可以在卷组上创建一个或多个LV（逻辑卷）。
*逻辑卷（Logical Volume，LV）：类似于非LVM系统中的磁盘分区，逻辑卷建立在卷组VG之上。在逻辑卷LV之上可以建立文件系统（比如/home或者/usr等）。
*逻辑块（Logical Extent，LE）：逻辑卷LV也被划分为可被寻址的基本单位，称为LE。在同一个卷组中，LE的大小和PE是相同的，并且一一对应。
