<p><span style="font-family: Microsoft YaHei; font-size: 15px">如果发现文件系统的容量不足了，可以通过 LVM 轻松的进行扩展(当然也可以进行缩减操作)。本文将紧接前文中的 demo 详细的介绍扩展文件系统的操作过程。说明：本文的演示环境为 ubuntu 16.04。</span></p>
<h2><span style="font-family: Microsoft YaHei; font-size: 18pt">警报：可用磁盘空间不足</span></h2>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">当我们收到可用磁盘空间不足的警报时，就需要去诊断磁盘空间相关的问题了。一般的结果是：增加磁盘容量(简单有效，清理掉一些看似没用的文件是件风险极大的事情)！</span><br><span style="font-family: Microsoft YaHei; font-size: 15px">df 命令可以帮助我们查看文件系统的容量：</span></p>
<p><span style="font-family: Microsoft YaHei; font-size: 15px"><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZPVFV5TURNekx6SXdNVGd4TWk4NU5USXdNek10TWpBeE9ERXlNVGt4TXpBMU1UVTVNakl0TVRZeE9EQTRPVGcxTkM1d2JtYz0=" alt=""></span></p>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">上图中的 LV nicklv00 的总容量为 15G，此时可用容量已经不足 1G了，我们接下来扩展这个 LV。</span></p>
<h2><span style="font-family: Microsoft YaHei; font-size: 18pt">查看当前系统中磁盘的概况</span></h2>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">在动手扩展文件系统的容量前，我们需要先搞清楚当前系统中磁盘的基本情况。lsblk 命令可以帮助我们查看系统上的所有块设备列表(下面命令中笔者通过 -e 选项排除了 loop 设备和光驱)：</span></p>
<div class="likecs_code">
<pre>$ lsblk -e <span style="color: #800080">7</span>,<span style="color: #800080">11</span></pre>

<p><span style="font-family: Microsoft YaHei; font-size: 15px">我们比较关注挂载点 /home/doc 对应的文件系统的情况：它的磁盘类型为 LVM，对应的 LV 名称为 nicklv00，LV 在名称为 nickvg 的 VG 中。其中磁盘的整个容量为 20G，而 LV 的容量只有 15G。我们先用 lvdisplay 命令来观察下 LV 的详细信息：</span></p>
<div class="likecs_code">
<pre>$ <span style="color: #0000ff">sudo</span> lvdisplay nickvg/nicklv00</pre>

<p><span style="font-family: Microsoft YaHei; font-size: 15px">这里比较重要的两点是 LV 的容量为 15G，它所属的 VG 名称为 nickvg。接下来用  vgdisplay 命令查看名称为 nickvg 的 VG 的详细信息：</span></p>
<div class="likecs_code">
<pre>$ <span style="color: #0000ff">sudo</span> vgdisplay nickvg</pre>
</div>
<p><span style="font-family: Microsoft YaHei; font-size: 15px"><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZPVFV5TURNekx6SXdNVGd4TWk4NU5USXdNek10TWpBeE9ERXlNVGt4TXpBM01UQXhNek10T1RjM01qUTNNVEV6TG5CdVp3PT0=" alt=""></span></p>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">上图显示 VG 的容量为 19.97G，已经分配了 15G，还有 4.97G 是空闲的。如果我们的要求不高，可以直接把 VG 中空闲的 4.97G 分配给 LV nicklv00，但是我们希望给 nicklv00 多分些空间，比如 50G。所以我们需要继续查看 VG 的底层构成。</span><br><span style="font-family: Microsoft YaHei; font-size: 15px">通过 pvs 可以查看 pv 与 vg 的组成关系：</span></p>
<div class="likecs_code">
<pre>$ <span style="color: #0000ff">sudo</span> pvs</pre>

<p><span style="font-family: Microsoft YaHei; font-size: 15px"><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZPVFV5TURNekx6SXdNVGd4TWk4NU5USXdNek10TWpBeE9ERXlNVGt4TXpBM05ESXdNVFF0T1RFNU5UY3lOall5TG5CdVp3PT0=" alt=""></span></p>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">VG nickvg 是由 PV /dev/sdd1 构成的，/dev/sdd1 的容量为 19.97G。要查看 PV 的详细信息，可以使用 pvdisplay 命令：</span></p>
<div class="likecs_code">
<pre>$ <span style="color: #0000ff">sudo</span> pvdisplay /dev/sdd1</pre>

<p><span style="font-family: Microsoft YaHei; font-size: 15px"><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZPVFV5TURNekx6SXdNVGd4TWk4NU5USXdNek10TWpBeE9ERXlNVGt4TXpBNE1UWXhPVGd0TWpBNU16QXpNRFUxTlM1d2JtYz0=" alt=""></span></p>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">至此我们已经搞清楚了系统当前的存储系统(忽略了我们不太关心的磁盘)，总结一下：硬盘设备 /dev/sdd 的容量为 20G，其上创建了一个 20G 的硬盘分区 /dev/sdd1，硬盘分区 /dev/sdd1 被创建为 LVM 的物理卷(PV，PV 的名称依然是 /dev/sdd1)，大小仍然为 20G。在物理卷 /dev/sdd1 上创建了容量为 20G 的卷组(VG) nickvg，在 nickvg 中有一个 15G大小的逻辑卷(LV) nickvg/nicklv00。文件系统就建立在 LV 上，挂载点为 /home/doc。</span></p>
<h2><span style="font-family: Microsoft YaHei; font-size: 18pt">扩展方案</span></h2>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">我们打算为 /home/doc 下挂载的文件系统增加 50G 的容量，因此仅仅利用 VG 中剩余的 4.97G 空间时不够的。简单起见，我们直接新增一块容量为 50G 的硬盘(此处为虚拟磁盘)，通过 LVM 添加到 VG 中，然后扩展 LV，并最终完成扩展文件系统的任务。</span></p>
<h2><span style="font-family: Microsoft YaHei; font-size: 18pt">添加磁盘并创建物理卷(PV)</span></h2>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">在虚拟机中添加虚拟磁盘并非难事，这里不再细说，笔者添加的磁盘设备文件为 /dev/sde：</span></p>

<h2><span style="font-family: Microsoft YaHei; font-size: 18pt">扩展文件系统</span></h2>
<p><span style="font-family: Microsoft YaHei; font-size: 15px"><a href="http://man7.org/linux/man-pages/man8/resize2fs.8.html" target="_blank" rel="nofollow">resize2fs 命令</a>用来扩展或收缩文件系统的容量，但是这个命令只支持 ext2、ext3、ext4 格式的文件系统。笔者的文件系统为 ext4，所以可以使用 resize2fs 命令进行扩展。这个命令还有一个特点，如果是扩展文件系统的容量，那么不管目标文件系统是否处于挂载状态都可以执行。如果是缩减文件系统的容量，则只能先卸载文件系统，缩减容量后再重新挂载文件系统。下面的命令把文件系统的容量扩展至 LV 的总容量：</span></p>

<p><span style="font-family: Microsoft YaHei; font-size: 15px">目标文件系统已经显示被扩展到了 64G(各种开销)，至此我们完成了文件系统的扩容任务。</span></p>
<h2><span style="font-family: Microsoft YaHei; font-size: 18pt">总结</span></h2>
<p><span style="font-family: Microsoft YaHei; font-size: 15px">使用 LVM 管理磁盘让文件系统的扩展/缩减变得非常容易，特别是可以自由的组合硬件磁盘为更大的容量单位(VG)，使系统维护者的工作变得轻松不少。除此之外，LVM 还支持快照等特色功能，笔者将在接下来的文章中介绍如何使用 LVM 的快照。</span></p>
