describe_volumes_modifications

EC2.Client.describe_volumes_modifications(**kwargs)

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 Monitor the progress of volume modifications in the Amazon Elastic Compute Cloud User Guide.

Request Syntax

response = client.describe_volumes_modifications(
    DryRun=True|False,
    VolumeIds=[
        'string',
    ],
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    NextToken='string',
    MaxResults=123
)

Parameters:

• DryRun (boolean) – 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.

• VolumeIds (list) –

  The IDs of the volumes.

  • (string) –

• Filters (list) –

  The filters.

  • 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.

  • (dict) –

    A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.

    If you specify multiple filters, the filters are joined with an AND, and the request returns only results that match all of the specified filters.

    • Name (string) –

      The name of the filter. Filter names are case-sensitive.

    • Values (list) –

      The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR, and the request returns all results that match any of the specified values.

      • (string) –

• NextToken (string) – The token returned by a previous paginated request. Pagination continues from the end of the items returned by the previous request.

• MaxResults (integer) – The maximum number of results (up to a limit of 500) to be returned in a paginated request. For more information, see Pagination.

Return type:
