title: error when resizing partition using `growpart` on AWS EBS instance
body: <p>I have an EC2 instance where I'm attempting to resize the disk on the fly. I've followed the instructions in this <a href="https://stackoverflow.com/a/42791031/7022062">SO post</a> but when I run <code>sudo growpart /dev/nvme0n1p1 1</code>, I get the following error:</p>
  <p><code>FAILED: failed to get start and end for /dev/nvme0n1p11 in /dev/nvme0n1p1</code></p>
  <p>What does this mean and how can I resolve it?</p>
  <hr />
  <p>More info:</p>
  <p>Output from <code>lsblk</code>:</p>
  <pre><code>NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
  nvme0n1     259:0    0   300G  0 disk
  └─nvme0n1p1 259:1    0   300G  0 part /
  </code></pre>
  <p>I can see that EBS volume is in the <code>in-use (optimizing)</code> state.</p>
  <p>Thanks in advance!</p>
