Request Parameters Response Elements Errors Examples See Also

DescribeVolumesModifications

Describes the most recent volume modification request for the specified EBS volumes.

If a volume has never been modified, some information in the output will be null. If a volume has been modified more than once, the output includes only the most recent modification request.

You can also use CloudWatch Events to check the status of a modification to an EBS volume. For information about CloudWatch Events, see the Amazon CloudWatch Events User Guide. For more information, see Monitoring volume modifications in the Amazon Elastic Compute Cloud User Guide.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No

Filter.N

modification-state - The current modification state (modifying | optimizing | completed | failed).
original-iops - The original IOPS rate of the volume.
original-size - The original size of the volume, in GiB.
original-volume-type - The original volume type of the volume (standard | io1 | io2 | gp2 | sc1 | st1).
originalMultiAttachEnabled - Indicates whether Multi-Attach support was enabled (true | false).
start-time - The modification start time.
target-iops - The target IOPS rate of the volume.
target-size - The target size of the volume, in GiB.
target-volume-type - The target volume type of the volume (standard | io1 | io2 | gp2 | sc1 | st1).
targetMultiAttachEnabled - Indicates whether Multi-Attach support is to be enabled (true | false).
volume-id - The ID of the volume.
