>Add Custom Storage Pools</a
>
</h1>
<p>
Using arclight, you can define Libvirt storage pools in the /var,
/mnt, and /media directories. This was done to prevent full access
to the operating system from the Web interface. If you need to
define a storage pool outside of these limitations, you can use
the terminal using Libvirt to register a storage pool. In this
example we will define the /home/ubuntu/ directory as a storage
pool.
</p>
<p>
Define the storage pool using the pool-define-as command from
virsh. We will pass in the type of storage devices which is a
directory, name which we will call myHomePool, and the filepath to
the storage pool.
</p>
<pre><code class="language-sh">virsh pool-define-as --type dir --name myHomePool --target /home/ubuntu
</code></pre>
<p>
The storage pool will now show up in arclight. If you wish to view
it in the terminal you can use the following command
</p>
<pre><code class="language-sh">virsh pool-list --all</code></pre>
<p>
The storage pool myHomePool will not be running, you can start it
using arclight, or in the terminal you can use the following
command to start the storage pool. Optionally you can use
pool-autostart to automatically start the pool upon the system
boot and use pool-autostart –disable to remove it.
</p>
<pre><code class="language-sh">virsh pool-start myHomePool</code></pre>
<p>
If you choose to stop the storage pool from running, you can do
this in arclight or by using the pool-destroy option.
</p>
<pre><code class="language-sh">virsh pool-destroy myHomePool</code></pre>
<p>
Lastly if you decide to remove the storage pool you can undefine
it. This will leave the directory intact on the operating system,
just removing it from the list of storage pools. Again, this can
be done in arclight or by using the pool-undefine option in the
terminal.
</p>
<pre><code class="language-sh">virsh pool-undefine myHomePool</code></pre>
