Synopsis

Invokes the CreateFileSystem operation against Amazon Elastic File System.

Syntax

New-EFSFileSystem
-CreationToken <String>
-Encrypted <Boolean>
-KmsKeyId <String>
-PerformanceMode <PerformanceMode>
-Force <SwitchParameter>

Description

Creates a new, empty file system. The operation requires a creation token in the request that Amazon EFS uses to ensure idempotent creation (calling the operation with same creation token has no effect). If a file system does not currently exist that is owned by the caller's AWS account with the specified creation token, this operation does the following:
  • Creates a new, empty file system. The file system will have an Amazon EFS assigned ID, and an initial lifecycle state creating.
  • Returns with the description of the created file system.
Otherwise, this operation returns a FileSystemAlreadyExists error with the ID of the existing file system. For basic use cases, you can use a randomly generated UUID for the creation token. The idempotent operation allows you to retry a CreateFileSystem call without risk of creating an extra file system. This can happen when an initial call fails in a way that leaves it uncertain whether or not a file system was actually created. An example might be that a transport level timeout occurred or your connection was reset. As long as you use the same creation token, if the initial call had succeeded in creating a file system, the client can learn of its existence from the FileSystemAlreadyExists error. The CreateFileSystem call returns while the file system's lifecycle state is still creating. You can check the file system creation status by calling the DescribeFileSystems operation, which among other things returns the file system state. This operation also takes an optional PerformanceMode parameter that you choose for your file system. We recommend generalPurpose performance mode for most file systems. File systems using the maxIO performance mode can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for most file operations. The performance mode can't be changed after the file system has been created. For more information, see Amazon EFS: Performance Modes. After the file system is fully created, Amazon EFS sets its lifecycle state to available, at which point you can create one or more mount targets for the file system in your VPC. For more information, see CreateMountTarget. You mount your Amazon EFS file system on an EC2 instances in your VPC via the mount target. For more information, see Amazon EFS: How it Works. This operation requires permissions for the elasticfilesystem:CreateFileSystem action.

Parameters

-CreationToken <String>
String of up to 64 ASCII characters. Amazon EFS uses this to ensure idempotent creation.
Required?False
Position?Named
Accept pipeline input?False
-Encrypted <Boolean>
A boolean value that, if true, creates an encrypted file system. When creating an encrypted file system, you have the option of specifying a CreateFileSystemRequest$KmsKeyId for an existing AWS Key Management Service (AWS KMS) customer master key (CMK). If you don't specify a CMK, then the default CMK for Amazon EFS, /aws/elasticfilesystem, is used to protect the encrypted file system.
Required?False
Position?Named
Accept pipeline input?False
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-KmsKeyId <String>
The id of the AWS KMS CMK that will be used to protect the encrypted file system. This parameter is only required if you want to use a non-default CMK. If this parameter is not specified, the default CMK for Amazon EFS is used. This id can be in one of the following formats:
  • Key ID - A unique identifier of the key. For example, 1234abcd-12ab-34cd-56ef-1234567890ab.
  • ARN - An Amazon Resource Name for the key. For example, arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab.
  • Key alias - A previously created display name for a key. For example, alias/projectKey1.
  • Key alias ARN - An Amazon Resource Name for a key alias. For example, arn:aws:kms:us-west-2:444455556666:alias/projectKey1.
Note that if the KmsKeyId is specified, the CreateFileSystemRequest$Encrypted parameter must be set to true.
Required?False
Position?Named
Accept pipeline input?False
-PerformanceMode <PerformanceMode>
The PerformanceMode of the file system. We recommend generalPurpose performance mode for most file systems. File systems using the maxIO performance mode can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for most file operations. This can't be changed after the file system has been created.
Required?False
Position?Named
Accept pipeline input?False

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

This cmdlet does not accept pipeline input.

Outputs

This cmdlet returns a Amazon.ElasticFileSystem.Model.CreateFileSystemResponse object containing multiple properties. The object can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
