I want to increase or decrease the size of my Amazon Elastic Block Store (Amazon EBS) volume.

Resolution

You can only increase the size of your Amazon EBS volume. You can't decrease an EBS volume's size. To use a smaller volume, create a smaller volume, and then use an application-level tool to migrate your data to the smaller volume.

For more information, see the following Amazon EBS documentation for both Linux and Windows operating systems:

If you use AWS SDKs to modify volumes, then refer to the documentation that's specific to your AWS SDK.

Why does EBS not offer a decrease functionality?

Hi Nischal, I think so it's not a problem of AWS but it's an issue related to the file system itself. Not all file systems/operating systems are capable of decreasing their size. So, AWS does not allow it.
