URI Request Parameters

The request uses the following URI parameters.

FileSystemId

The ID of the file system that you want to update.

Length Constraints: Maximum length of 128.

Pattern: ^(arn:aws[-a-z]*:elasticfilesystem:[0-9a-z-:]+:file-system/fs-[0-9a-f]{8,40}|fs-[0-9a-f]{8,40})$

Required: Yes

Request Body

The request accepts the following data in JSON format.

ProvisionedThroughputInMibps

(Optional) Sets the amount of provisioned throughput, in MiB/s, for the file system. Valid values are 1-1024. If you are changing the throughput mode to provisioned, you must also provide the amount of provisioned throughput. Required if ThroughputMode is changed to provisioned on update.

Type: Double

Valid Range: Minimum value of 1.0.

Required: No

ThroughputMode

(Optional) Updates the file system's throughput mode. If you're not updating your throughput mode, you don't need to provide this value in your request. If you are changing the ThroughputMode to provisioned, you must also set a value for ProvisionedThroughputInMibps.

Type: String

Valid Values: bursting | provisioned

Required: No

Response Elements

If the action is successful, the service sends back an HTTP 202 response.

The following data is returned in JSON format by the service.

AvailabilityZoneId

The unique and consistent identifier of the Availability Zone in which the file system's One Zone storage classes exist. For example, use1-az1 is an Availability Zone ID for the us-east-1 AWS Region, and it has the same location in every AWS account.

Type: String

AvailabilityZoneName

Describes the AWS Availability Zone in which the file system is located, and is valid only for file systems using One Zone storage classes. For more information, see Using EFS storage classes in the Amazon EFS User Guide.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: .+

CreationTime

The time that the file system was created, in seconds (since 1970-01-01T00:00:00Z).

Type: Timestamp

CreationToken

The opaque string specified in the request.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: .+

Encrypted

A Boolean value that, if true, indicates that the file system is encrypted.

Type: Boolean

FileSystemArn

The Amazon Resource Name (ARN) for the EFS file system, in the format arn:aws:elasticfilesystem:region:account-id:file-system/file-system-id. Example with sample data: arn:aws:elasticfilesystem:us-west-2:1111333322228888:file-system/fs-01234567

Type: String

FileSystemId

The ID of the file system, assigned by Amazon EFS.

Type: String

Length Constraints: Maximum length of 128.

Pattern: ^(arn:aws[-a-z]*:elasticfilesystem:[0-9a-z-:]+:file-system/fs-[0-9a-f]{8,40}|fs-[0-9a-f]{8,40})$

KmsKeyId

The ID of an AWS Key Management Service customer master key (CMK) that was used to protect the encrypted file system.

Type: String

Length Constraints: Maximum length of 2048.

Pattern: ^([0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}|mrk-[0-9a-f]{32}|alias/[a-zA-Z0-9/_-]+|(arn:aws[-a-z]*:kms:[a-z0-9-]+:\d{12}:((key/[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})|(key/mrk-[0-9a-f]{32})|(alias/[a-zA-Z0-9/_-]+))))$

LifeCycleState

The lifecycle phase of the file system.

Type: String

Name

You can add tags to a file system, including a Name tag. For more information, see CreateFileSystem. If the file system has a Name tag, Amazon EFS returns the value in this field.

Type: String

Length Constraints: Maximum length of 256.

Pattern: ^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$

NumberOfMountTargets

The current number of mount targets that the file system has. For more information, see CreateMountTarget.

Type: Integer

Valid Range: Minimum value of 0.

OwnerId

The AWS account that created the file system. If the file system was created by an IAM user, the parent account to which the user belongs is the owner.

Type: String

Length Constraints: Maximum length of 14.

Pattern: ^(\d{12})|(\d{4}-\d{4}-\d{4})$

PerformanceMode

The performance mode of the file system.

Type: String

Valid Values: generalPurpose | maxIO

ProvisionedThroughputInMibps

The amount of provisioned throughput, measured in MiB/s, for the file system. Valid for file systems using ThroughputMode set to provisioned.

Type: Double

Valid Range: Minimum value of 1.0.

SizeInBytes

The latest known metered size (in bytes) of data stored in the file system, in its Value field, and the time at which that size was determined in its Timestamp field. The Timestamp value is the integer number of seconds since 1970-01-01T00:00:00Z. The SizeInBytes value doesn't represent the size of a consistent snapshot of the file system, but it is eventually consistent when there are no writes to the file system. That is, SizeInBytes represents actual size only if the file system is not modified for a period longer than a couple of hours. Otherwise, the value is not the exact size that the file system was at any point in time.

Type: FileSystemSize object

Tags

The tags associated with the file system, presented as an array of Tag objects.

Type: Array of Tag objects

ThroughputMode

Displays the file system's throughput mode. For more information, see Throughput modes in the Amazon EFS User Guide.

Type: String

Valid Values: bursting | provisioned

Errors

BadRequest

Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.

HTTP Status Code: 400

FileSystemNotFound

Returned if the specified FileSystemId value doesn't exist in the requester's AWS account.

HTTP Status Code: 404

IncorrectFileSystemLifeCycleState

Returned if the file system's lifecycle state is not "available".

HTTP Status Code: 409

InsufficientThroughputCapacity

Returned if there's not enough capacity to provision additional throughput. This value might be returned when you try to create a file system in provisioned throughput mode, when you attempt to increase the provisioned throughput of an existing file system, or when you attempt to change an existing file system from bursting to provisioned throughput mode. Try again later.

HTTP Status Code: 503

InternalServerError

Returned if an error occurred on the server side.

HTTP Status Code: 500

ThroughputLimitExceeded

Returned if the throughput mode or amount of provisioned throughput can't be changed because the throughput limit of 1024 MiB/s has been reached.

HTTP Status Code: 400

TooManyRequests

Returned if you don’t wait at least 24 hours before changing the throughput mode, or decreasing the Provisioned Throughput value.

HTTP Status Code: 429
