title: Terraform aws_instance - changing volume_size
body: <p>I am trying to increase size of my root volume for my ami <code>ami-0d013c5896434b38a</code> - I am using terraform to provision this.</p>
  <p>Just to clarify - I have only 1 instance. And I want to make sure that if I need to increase the disk space, I don't have to destroy the machine first. Elasticity (EC2)  is my reason to believe that it's doable.</p>
  <p>Does anyone know whether this is doable? Yes, I could simply do <code>terraform plan</code> and do a dry-run, but just double-checking.</p>
