I need to increase or decrease the size of my Amazon Elastic Block Store (Amazon EBS) volume. How to do this?
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:
- Requirements when modifying volumes
- Request modifications to your EBS volumes
- Tutorial: Increase the size of an Amazon EBS volume on an Amazon Elastic Compute Cloud (Amazon EC2) instance
If you're using an AWS SDK to modify your volume, refer to the documentation that's specific to your AWS SDK.
