describe-volumes

Description

Describes the specified EBS volumes or all of your EBS volumes.

If you are describing a long list of volumes, we recommend that you paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeVolumes request to retrieve the remaining results.

For more information about EBS volumes, see Amazon EBS volumes in the Amazon Elastic Compute Cloud User Guide .

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

describe-volumes is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Volumes

Synopsis

  describe-volumes
[--filters <value>]
[--volume-ids <value>]
[--dry-run | --no-dry-run]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--filters (list)

The filters.

• attachment.attach-time - The time stamp when the attachment initiated.

• attachment.delete-on-termination - Whether the volume is deleted on instance termination.

• attachment.device - The device name specified in the block device mapping (for example, /dev/sda1 ).

• attachment.instance-id - The ID of the instance the volume is attached to.

• attachment.status - The attachment state (attaching | attached | detaching ).

• availability-zone - The Availability Zone in which the volume was created.

• create-time - The time stamp when the volume was created.

• encrypted - Indicates whether the volume is encrypted (true | false )

• multi-attach-enabled - Indicates whether the volume is enabled for Multi-Attach (true | false )

• fast-restored - Indicates whether the volume was created from a snapshot that is enabled for fast snapshot restore (true | false ).

• size - The size of the volume, in GiB.

• snapshot-id - The snapshot from which the volume was created.

• status - The state of the volume (creating | available | in-use | deleting | deleted | error ).

• tag :<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA , specify tag:Owner for the filter name and TeamA for the filter value.

• tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

• volume-id - The volume ID.

• volume-type - The Amazon EBS volume type (gp2 | gp3 | io1 | io2 | st1 | sc1 | standard )

(structure)

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.

Name -> (string)

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

Values -> (list)

The filter values. Filter values are case-sensitive.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--volume-ids (list)

The volume IDs.

(string)

Syntax:

"string" "string" ...

--dry-run | --no-dry-run (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 .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

            "Size": 100
        }
    ]
}

Example 2: To describe volumes that are attached to a specific instance

The following describe-volumes example describes all volumes that are both attached to the specified instance and set to delete when the instance terminates.

aws ec2 describe-volumes \
    --region us-east-1 \
    --filters Name=attachment.instance-id,Values=i-1234567890abcdef0 Name=attachment.delete-on-termination,Values=true

For an example of the output for describe-volumes, see Example 1.

Example 3: To describe available volumes in a specific Availability Zone

The following describe-volumes example describes all volumes that have a status of available and are in the specified Availability Zone.

aws ec2 describe-volumes \
    --filters Name=status,Values=available Name=availability-zone,Values=us-east-1a

For an example of the output for describe-volumes, see Example 1.

Example 4: To describe volumes based on tags

The following describe-volumes example describes all volumes that have the tag key Name and a value that begins with Test. The output is then filtered with a query that displays only the tags and IDs of the volumes.

aws ec2 describe-volumes \
    --filters Name=tag:Name,Values=Test* \
    --query "Volumes[*].{ID:VolumeId,Tag:Tags}"

Output:

[
    {
       "Tag": [
           {
               "Value": "Test2",
               "Key": "Name"
           }
       ],
       "ID": "vol-1234567890abcdef0"
   },
   {
       "Tag": [
           {
               "Value": "Test1",
               "Key": "Name"
           }
       ],
       "ID": "vol-049df61146c4d7901"
    }
]
