/**

 * <p>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 <a href="https://docs.aws.amazon.com/ebs/latest/userguide/ebs-modify-volume.html">Amazon EBS Elastic Volumes</a>
 *       in the <i>Amazon EBS User Guide</i>.</p>
 *          <p>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 <a href="https://docs.aws.amazon.com/ebs/latest/userguide/recognize-expanded-volume-linux.html">Extend the file system</a>.</p>
 *          <p> You can use CloudWatch Events to check the status of a modification to an EBS volume. For
 *       information about CloudWatch Events, see the <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/">Amazon CloudWatch Events User Guide</a>. You can also track the status of a
 *       modification using <a>DescribeVolumesModifications</a>. For information
 *       about tracking status changes using either method, see <a href="https://docs.aws.amazon.com/ebs/latest/userguide/monitoring-volume-modifications.html">Monitor the progress of volume modifications</a>.</p>
 *          <p>With previous-generation instance types, resizing an EBS volume might require detaching and
 *       reattaching the volume or stopping and restarting the instance.</p>
 *          <p>After modifying a volume, you must wait at least six hours and ensure that the volume
 *       is in the <code>in-use</code> or <code>available</code> state before you can modify the same
 *       volume. This is sometimes referred to as a cooldown period.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, ModifyVolumeCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, ModifyVolumeCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const input = { // ModifyVolumeRequest
 *   DryRun: true || false,
 *   VolumeId: "STRING_VALUE", // required
 *   Size: Number("int"),
 *   VolumeType: "standard" || "io1" || "io2" || "gp2" || "sc1" || "st1" || "gp3",
 *   Iops: Number("int"),
 *   Throughput: Number("int"),
 *   MultiAttachEnabled: true || false,
 * };
 * const command = new ModifyVolumeCommand(input);
 * const response = await client.send(command);
 * // { // ModifyVolumeResult
 * //   VolumeModification: { // VolumeModification
 * //     VolumeId: "STRING_VALUE",
 * //     ModificationState: "modifying" || "optimizing" || "completed" || "failed",
 * //     StatusMessage: "STRING_VALUE",
 * //     TargetSize: Number("int"),
 * //     TargetIops: Number("int"),
 * //     TargetVolumeType: "standard" || "io1" || "io2" || "gp2" || "sc1" || "st1" || "gp3",
 * //     TargetThroughput: Number("int"),
 * //     TargetMultiAttachEnabled: true || false,
 * //     OriginalSize: Number("int"),
 * //     OriginalIops: Number("int"),
 * //     OriginalVolumeType: "standard" || "io1" || "io2" || "gp2" || "sc1" || "st1" || "gp3",
 * //     OriginalThroughput: Number("int"),
