// You can modify several parameters of an existing EBS volume, including volume
// size, volume type, and IOPS capacity. If your EBS volume is attached to a
// current-generation EC2 instance type, you might be able to apply these changes
// without stopping the instance or detaching the volume from it. For more
// information about modifying EBS volumes, see [Amazon EBS Elastic Volumes]in the Amazon EBS User Guide.
//
// When you complete a resize operation on your volume, you need to extend the
// volume's file-system size to take advantage of the new storage capacity. For
// more information, see [Extend the file system].
//
// For more information, see [Monitor the progress of volume modifications] in the Amazon EBS User Guide.
//
// With previous-generation instance types, resizing an EBS volume might require
// detaching and reattaching the volume or stopping and restarting the instance.
//
// After modifying a volume, you must wait at least six hours and ensure that the
// volume is in the in-use or available state before you can modify the same
// volume. This is sometimes referred to as a cooldown period.
