title: Can an existing device-name be given to a new EBS volume being attached to an Amazon EC2 instance?
body: <p>Let's say there is a single disk <code>Disk 0</code> at an Amazon EC2 instance <code>Instance1</code> with the corresponding EBS volume having the device-name <code>/dev/sd1</code>. Let's say this disk maps to C-drive on the VM.</p>
  <p>Now can we create a new EBS volume attach it to <code>Instance1</code> with the same device-name <code>/dev/sd1</code>?</p>
  <p>If this is possible, does it mean, after the volume is attached, we can go ahead and extend the existing C-drive at <code>Instance1</code>, without having to go through the process of detaching it first, creating a snapshot etc.?</p>
