<h1>Faster Partitioning with Sgdisk</h1>
|
||
|
||
<p>date: 2019-02-11T04:23:52-08:00</p>
|
||
<h2 id="disclaimer"><strong>Disclaimer</strong></h2>
|
||
<p>If any of this is wrong, let me know so I can fix it. No actual hard drives were harmed in the production of this blog post.</p>
|
||
<p>The examples are easier to read if you turn your smart phone sideways.</p>
|
||
<h2 id="command-line-is-faster"><strong>Command Line Is Faster</strong></h2>
|
||
<p>Sure you can partition your discs using a GUI disk management application or an interactive,
|
||
menu-driven terminal interface. But the command line is faster.</p>
|
||
<h2 id="gdisk-vs-sgdisk"><strong>gdisk vs sgdisk</strong></h2>
|
||
<p><code>sgdisk</code> is the scriptable version of <code>gdisk</code> (gptfdisk).</p>
|
||
<h2 id="what-the-manpage-says"><strong><a href="https://manpages.debian.org/stretch/gdisk/sgdisk.8.en.html" target="_blank">what the manpage says</a></strong></h2>
|
||
<p>If you’re familiar with <code>gdisk</code>, you probably know how to interactively set the partition size and type.
|
||
If you look at the man page for <code>sgdisk</code> you see that the relevant flags are <code>-n</code> and <code>-t</code>. The beginning and ending numbers
|
||
are absolute, unless you prepend them with a <code>+</code> or <code>-</code> sign, in which case they become relative.
|
||
<div class="highlight"><pre><span></span><code><span class="gp"># </span>For New Partition:
|
||
<span class="go">-n, --new=partnum:start:end</span>
|
||
</code></pre></div>
|
||
<div class="highlight"><pre><span></span><code><span class="gp"># </span>Change partition type:
|
||
<span class="go">-t, --typecode=partnum:{hexcode|GUID}</span>
|
||
</code></pre></div></p>
|
||
<h2 id="example-with-separate-efi-and-partitions"><strong>Example with Separate EFI and / Partitions</strong></h2>
|
||
<p>BTW, <code>gdisk</code> is a partitioning tool intended to be used with a gpt partition table, so the assumption is that you would want an efi partition,</p>
|
||
<p>(although the efi partition does not have to be on the disk you are partitioning or even on the same disk where your other system partitions are).</p>
|
||
<ol>
|
||
<li>Wipe any leftover filesystem metadata with wipefs.
|
||
<div class="highlight"><pre><span></span><code><span class="go">wipefs --all /dev/sdx</span>
|
||
</code></pre></div></li>
|
||
<li>Create a new GPT partition table.
|
||
<div class="highlight"><pre><span></span><code><span class="go">sgdisk /dev/sdx -o</span>
|
||
</code></pre></div></li>
|
||
<li>Create an efi partition of 512MB by specifying the end of the partition (relative) and the partition type, <code>ef00</code>.
|
||
<div class="highlight"><pre><span></span><code><span class="go">sgdisk /dev/sdx -n 1::+512MiB -t 1:ef00</span>
|
||
</code></pre></div></li>
|
||
<li>Create an <code>/</code> partition using the remainder of the disk, by not specifying the end or the beginning or partition type, which defaults to 8300.
|
||
<div class="highlight"><pre><span></span><code><span class="go">sgdisk /dev/sdx -n 2</span>
|
||
</code></pre></div></li>
|
||
<li>Format the efi partition fat 32.
|
||
<div class="highlight"><pre><span></span><code><span class="go">mkfs.vfat -F32 /dev/sdx1</span>
|

|

<li>Format the <code>/</code> partition ext4.
|
||
<div class="highlight"><pre><span></span><code><span class="go">mkfs.ext4 /dev/sdx2</span>
|
||
</code></pre></div></li>
|
||
</ol>
|
||
<h2 id="practice-with-a-sparse-image"><strong>Practice With A Sparse Image</strong></h2>
|
||
<p>If you don’t want to partition a real hard drive, you can practice using an sparse image file, instead.
|
||
<div class="highlight"><pre><span></span><code><span class="gp"># </span>create a sparse image file
|
||
<span class="go">truncate -S 100G practiceImage.img</span>

<span class="gp"># </span>partition the image file with sgdisk
|

<span class="go">sgdisk practiceImage.img -o</span>

|

</code></pre></div></li>
|

<li>Create a <code>/boot</code> partition of 1GB, by specifying the end of the partition (relative), but not specifying the partition type which defaults to <code>8300</code>.
|

<div class="highlight"><pre><span></span><code><span class="go">sgdisk /dev/sdx -n 2::+1GiB</span>
