详解Linux 虚拟机根分区磁盘扩充空间记录
<p>博主：centos6.5 64 位 vm 11</p>
<p>
起因：想让vm11里的linux虚拟机全屏显示，想支持虚拟机与物理机之间的无缝复制粘贴功能。安装vmware tools 导致空间不足，出现如下</p>

<p>
网上查找后发现解决方法：</p>

<p>
提示是空间不足</p>
<p>
进行查看：</p>

<p>
果然，空间利用100%</p>
<p>
问题转向：</p>
<p>
1.为何使用如此之快？</p>
<p>
2.如何扩充？</p>
<p>
问题1：</p>
<p>
此为根目录，安装的东西都在里面。（此过简略，并没有深入研究）</p>
<p>
正题：</p>
<p>
由此，花了大概2个小时解决，记录如下：</p>
<p>
<strong>1.磁盘扩充 </strong></p>

填入你需要磁盘的大小，填入的数值-当下硬盘的大小数值=你所增加的</p>
<p>
<strong>2.查看， </strong></p>
<p>
命令: fdisk -l (root用户)</p>

发现已经变成21.5g了</p>
<p>
<strong>3.操作分区表 </strong></p>
<p>
命令：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_231477">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">fdisk</code> <code class="bash plain">/dev/sda</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>

<p>
键入p 查看分区数量，得到：</p>
<p>

<p>
由此判断我们增加的分区号应该为3(dev/sda1,dev/sda2……接下来应该是dev/sda3了吧)</p>
<p>
键入n，增加一个分区，得到：</p>
<p>

<p>
键入 p，主分区，并键入3（编号）：</p>

<p>
默认起始扇区和结束扇区即可(键入两次enter)</p>
<p>
键入t，修改分区类型为8e：</p>

<p>
键入w，写分区表，然后重启：</p>

<p>
<strong>4.格式化 </strong></p>
<p>
mkfs.etx4 /dev/sda3</p>
<p>
.ext4是自己的文件系统类型，如果不知道的话，可以查询：</p>

<strong>5.卷扩容，添加进lvm组：</strong></p>
<p>
lvm> pvcreate /dev/sda3 初始化刚才的分区</p>
<p>

<p>
lvm> vgextend vg_master /dev/sda3 将初始化过的分区加入到虚拟卷组vg_master</p>
<p>
lvm>lvextend -l +12g /dev/vg_master/lv_root 扩展已有卷的容量</p>
<p>

<p>
lvm>pvdisplay 查看卷容量</p>

<p>
lvm>quit </p>
<p>
<strong>6.文件系统扩容</strong></p>
