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:

*   [Requirements for Amazon EBS volume modifications](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/modify-volume-requirements.html)
*   [Request Amazon EBS volume modifications](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/requesting-ebs-volume-modifications.html)
*   [Extend the file system after resizing an Amazon EBS volume](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html)

If you use AWS SDKs to modify volumes, then refer to the [documentation that's specific to your AWS SDK](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifyVolume.html#API_ModifyVolume_SeeAlso).

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.

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