Modifying an EBS Volume from the Console

The following procedure shows how to apply available volume modifications from the Amazon EC2 console.

To modify an EBS volume using the console

  1. Open the Amazon EC2 console at

  2. Choose Volumes, select the volume to modify, and then choose Actions, Modify Volume.

  3. The Modify Volume window displays the volume ID and the volume's current configuration, including type, size, and IOPS. You can change any or all of these settings in a single action. Set new configuration values as follows:

    • To modify the type, choose a value for Volume Type.

    • To modify the size, enter an allowed integer value for Size.

    • If you chose Provisioned IOPS (IO1) as your volume type, enter an allowed integer value for IOPS.

  4. After you have specified all of the modifications to apply, choose Modify, Yes.

  5. Modifying volume size has no practical effect until you also extend the volume's file system to make use of the new storage capacity. For more information, see Extending a Windows File System after Resizing the Volume.

  6. If you increase the size of an NVMe volume on an instance that does not have the AWS NVMe drivers, you must reboot the instance to enable Windows to see the new volume size. For more information about installing the AWS NVMe drivers, see AWS NVMe Drivers for Windows Instances.
