title: Increase the root volume (Hard disk) of EC2 Linux running instance without restart - Step by step process
body: <h1>Problem:</h1>
  <p>I have EC2 instance with Linux (Ubunty) and root volume of 10 GB. I have consumed about   96% of the size and now my application responding slow, so I wanted to increase the size to 50 GB.</p>
  <p>The most important point is, I have data already there and many applications are running on this EC2 instance and I don't want to disturb or stop them.</p>
  <p>To check the current space available  <code>~$ df -hT</code></p>

  <p>Please use <code>~$ lsblk</code> command to check the partition size</p>
