I need to increase or decrease the size of my Amazon Elastic Block Store (Amazon EBS) volume. How to do this?

Resolution

You can only increase the size of your Amazon EBS volume. You can't decrease volume size. If you want to have a smaller volume size, first create a smaller volume. Then, migrate your data to it using an application-level tool.

For more information, see the following Amazon EBS AWS Documentation:

If you're using an AWS SDK to modify your volume, refer to the documentation that's specific to your AWS SDK.
