|

<p>Clear Linux* OS pre-built images come in different sizes, ranging from 300 MB to 20
|
|
GB. This guide describes how to increase the disk size of your pre-built
|
|
image if you need more capacity. We will use the <a class="reference internal" href="../../get-started/virtual-machine-install/kvm.html#kvm"><span class="std std-ref">KVM image</span></a> as
|
|
an example to demonstrate the process of increasing disk size and expanding
|
|
the last partition to take up the added space.</p>

<p>There are two methods to find the disk size and the list of partitions of

a pre-built Clear Linux OS image.</p>

<section id="method-1-use-lsblk-on-the-vm">

<h3>Method 1: Use <strong class="command">lsblk</strong> on the VM<a class="headerlink" href="#method-1-use-lsblk-on-the-vm" title="Link to this heading">¶</a></h3>
|
|
<p>The first method is to boot up your VM and execute the <strong class="command">lsblk</strong>

command as shown below:</p>

<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>lsblk

<p>An example output of the <strong class="command">lsblk</strong> command:</p>

<div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="go">NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT</span>
|

<span class="go">fd0 2:0 1 4K 0 disk</span>

<h3>Method 2: Look at the image configuration YAML file<a class="headerlink" href="#method-2-look-at-the-image-configuration-yaml-file" title="Link to this heading">¶</a></h3>
|
|
<p>The second method to look at the image configuration YAML file that was
|
|
used to produce the image.</p>
|
|
<p>For example, to find the size of the KVM image version number 31880,
|
|
follow these steps:</p>
|
|
<ol class="arabic">
|
|
<li><p>Go to the <a class="reference external" href="https://cdn.download.clearlinux.org/releases/">releases</a> repository.</p></li>
|
|
<li><p>Drill down into the <cite>31880 > clear > config > image</cite> directory.</p></li>
|
|
<li><p>Download and open the <code class="file docutils literal notranslate"><span class="pre">kvm.yaml</span></code> file.</p></li>
|
|
<li><p>Locate the <cite>targetMedia</cite> section.</p>
|
|
<p>The example shows a total disk size of 8.54 GB, 512 MB for the EFI
|
|
partition, 32 MB for the swap partition, and 8 GB for the root partition.</p>

<p>Before you can expand the last partition of your image, you must make

space available by increasing the virtual disk size. After that, you

can resize the last partition and finally resize the filesystem.
