# DescribeVolumesModifications


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

For more information, see [ Monitor the progress of volume modifications](https://docs.aws.amazon.com/ebs/latest/userguide/monitoring-volume-modifications.html) in the *Amazon EBS 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](CommonParameters.md).

 **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**   
The filters.  
+  `modification-state` - The current modification state (modifying \$1 optimizing \$1 completed \$1 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 \$1 io1 \$1 io2 \$1 gp2 \$1 sc1 \$1 st1).
+  `originalMultiAttachEnabled` - Indicates whether Multi-Attach support was enabled (true \$1 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 \$1 io1 \$1 io2 \$1 gp2 \$1 sc1 \$1 st1).
+  `targetMultiAttachEnabled` - Indicates whether Multi-Attach support is to be enabled (true \$1 false).
+  `volume-id` - The ID of the volume.
Type: Array of [Filter](API_Filter.md) objects  
Required: No

 **MaxResults**   
The maximum number of results (up to a limit of 500) to be returned in a paginated request. For more information, see [Pagination](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/Query-Requests.html#api-pagination).  
Type: Integer  
Required: No

 **NextToken**   
The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.  
Type: String  
Required: No

 **VolumeId.N**   
The IDs of the volumes.  
Type: Array of strings  
Required: No

## Response Elements


The following elements are returned by the service.

 **nextToken**   
The token to include in another request to get the next page of items. This value is `null` when there are no more items to return.  
Type: String

 **requestId**   
The ID of the request.  
Type: String

 **volumeModificationSet**   
Information about the volume modifications.  
Type: Array of [VolumeModification](API_VolumeModification.md) objects

## Errors


For information about the errors that are common to all actions, see [Common client error codes](errors-overview.md#CommonErrors).
