describe-volumes

Description

Describes the specified EBS volumes.

If you are describing a long list of volumes, you can 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 describe-volumes 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

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 <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--filters (list)

One or more 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 | detached ).
  • availability-zone - The Availability Zone in which the volume was created.
  • create-time - The time stamp when the volume was created.
  • encrypted - The encryption status of the volume.
  • size - The size of the volume, in GiB.
  • snapshot-id - The snapshot from which the volume was created.
  • status - The status of the volume (creating | available | in-use | deleting | deleted | error ).
  • tag :key =*value* - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify tag:Purpose for the filter name and X for the filter value.
  • tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag :key =*value* filter.
  • tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.
  • volume-id - The volume ID.
  • volume-type - The Amazon EBS volume type. This can be gp2 for General Purpose SSD, io1 for Provisioned IOPS SSD, st1 for Throughput Optimized HDD, sc1 for Cold HDD, or standard for Magnetic volumes.

Shorthand Syntax:

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

JSON Syntax:

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

--volume-ids (list)

One or more volume IDs.

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 (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To describe all volumes

This example command describes all of your volumes in the default region.

Command:

aws ec2 describe-volumes

Output:

{
    "Volumes": [
        {
            "AvailabilityZone": "us-east-1a",
            "Attachments": [

To describe volumes that are attached to a specific instance

This example command describes all volumes that are both attached to the instance with the ID i-1234567890abcdef0 and set to delete when the instance terminates.

Command:

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

Output:

{
    "Volumes": [
        {
            "AvailabilityZone": "us-east-1a",
            "Attachments": [
                {
                    "AttachTime": "2013-12-18T22:35:00.000Z",
                    "InstanceId": "i-1234567890abcdef0",
                    "VolumeId": "vol-049df61146c4d7901",
                    "State": "attached",
                    "DeleteOnTermination": true,
                    "Device": "/dev/sda1"
                }
            ],
            "VolumeType": "standard",
            "VolumeId": "vol-049df61146c4d7901",
            "State": "in-use",

            "Size": 8
        }
    ]
}

To describe tagged volumes and filter the output

This example command describes all volumes that have the tag key Name and a value that begins with Test. The output is filtered to display only the tags and IDs of the volumes.

Command:

aws ec2 describe-volumes --filters Name=tag-key,Values="Name" Name=tag-value,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"
  }
]
