<p>On February 2017, <span class="caps">AWS</span> <a href="https://aws.amazon.com/blogs/aws/amazon-ebs-update-new-elastic-volumes-change-everything/">announced</a> the availability of a new <span class="caps">EBS</span> feature called Elastic Volumes. The new feature allows you to increase the size, performance and type and of your <span class="caps">EBS</span> volumes while in use. In order to take adantage of this great feature some requisites needs to be done.</p>
<ul>
<li>The volume needs to be attached to a compatible instance: C1, C3, <span class="caps">CC2</span>, <span class="caps">CR1</span>, G2, I2, M1, M3 y R3 and later. </li>
<li>The volume was attached to the instance after the November 1 of 2016.</li>
</ul>
<p>To modify the volumen size just type the new volumen size using the “Modify Volume” action on the <span class="caps">AWS</span> Console.</p>
<p><img alt="EBS volume resize" src="/images/ebs-resize.png" class="img-fluid border rounded shadow image-process-article-photo"></p>
<p>Note: depending on the new size the action can takes several hours.</p>
<p>Once the action completes, log into the instance and expand de filesystem. In my case since I’m using <span class="caps">LVM</span> I need to expand the physical and logical volumes.</p>
<div class="highlight pygments-style-monokai rounded shadow-sm mb-3"><pre><span></span><code>pvdisplay
pvscan
pvresize /dev/xvdg
pvdisplay
lvdisplay

</code></pre></div>
<p>And finally the ext4 filesystem:</p>

<small>Siempre había pensado que cuando los comandos du -hsx . y df -h . reportaban tamaños significativamente diferentes, estábamos ante un filesystem corrrupto, y que en estos casos la solución pasaba por hacer un fsck de dicho filesystem.
