Why isn’t my EBS volume increase reflected in my OS or Disk Management?

Last updated: 2019-10-17

I increased the size of my Amazon Elastic Block Store (Amazon EBS) volume, but the change isn’t reflected in my operating system or Disk Management. What do I need to do?

Resolution

Modifying an EBS volume requires two steps. First, increase the size of the EBS volume using the Amazon Elastic Compute Cloud (Amazon EC2) console or the AWS Command Line Interface (CLI). Then, you must extend the volume’s file system to use the new storage capacity. For instructions, see:
