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 Amazon Web Services 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. For more information, see Creating a file system in the Amazon EFS User Guide. 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 accepts 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. You can set the throughput mode for the file system using the ThroughputMode parameter. 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 by using the mount target. For more information, see Amazon EFS: How it Works. This operation requires permissions for the elasticfilesystem:CreateFileSystem action.

Parameters

-AvailabilityZoneName <String>
Used to create a file system that uses One Zone storage classes. It specifies the Amazon Web Services Availability Zone in which to create the file system. Use the format us-east-1a to specify the Availability Zone. For more information about One Zone storage classes, see Using EFS storage classes in the Amazon EFS User Guide.One Zone storage classes are not available in all Availability Zones in Amazon Web Services Regions where Amazon EFS is available.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Backup <Boolean>
Specifies whether automatic backups are enabled on the file system that you are creating. Set the value to true to enable automatic backups. If you are creating a file system that uses One Zone storage classes, automatic backups are enabled by default. For more information, see Automatic backups in the Amazon EFS User Guide.Default is false. However, if you specify an AvailabilityZoneName, the default is true.Backup is not available in all Amazon Web Services Regions where Amazon EFS is available.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientConfig <AmazonElasticFileSystemConfig>
Amazon.PowerShell.Cmdlets.EFS.AmazonElasticFileSystemClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-CreationToken <String>
A string of up to 64 ASCII characters. Amazon EFS uses this to ensure idempotent creation.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-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 an existing Key Management Service key (KMS key). If you don't specify a KMS key, then the default KMS key for Amazon EFS, /aws/elasticfilesystem, is used to protect the encrypted file system.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-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?True (ByPropertyName)
-KmsKeyId <String>
The ID of the KMS key that you want to use to protect the encrypted file system. This parameter is required only if you want to use a non-default KMS key. If this parameter is not specified, the default KMS key for Amazon EFS is used. You can specify a KMS key ID using the following formats:
  • Key ID - A unique identifier of the key, for example 1234abcd-12ab-34cd-56ef-1234567890ab.
  • ARN - An Amazon Resource Name (ARN) 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 ARN for a key alias, for example arn:aws:kms:us-west-2:444455556666:alias/projectKey1.
If you use KmsKeyId, you must set the CreateFileSystemRequest$Encrypted parameter to true.EFS accepts only symmetric KMS keys. You cannot use asymmetric KMS keys with Amazon EFS file systems.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PerformanceMode <PerformanceMode>
The performance mode 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. The performance mode can't be changed after the file system has been created.The maxIO mode is not supported on file systems using One Zone storage classes.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ProvisionedThroughputInMibp <Double>
The throughput, measured in MiB/s, that you want to provision for a file system that you're creating. Valid values are 1-1024. Required if ThroughputMode is set to provisioned. The upper limit for throughput is 1024 MiB/s. To increase this limit, contact Amazon Web Services Support. For more information, see Amazon EFS quotas that you can increase in the Amazon EFS User Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesProvisionedThroughputInMibps
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ElasticFileSystem.Model.CreateFileSystemResponse). Specifying the name of a property of type Amazon.ElasticFileSystem.Model.CreateFileSystemResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Tag <Tag[]>
Use to create one or more tags associated with the file system. Each tag is a user-defined key-value pair. Name your file system on creation by including a "Key":"Name","Value":"{value}" key-value pair. Each key must be unique. For more information, see Tagging Amazon Web Services resources in the Amazon Web Services General Reference Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesTags
-ThroughputMode <ThroughputMode>
Specifies the throughput mode for the file system. The mode can be bursting, provisioned, or elastic. If you set ThroughputMode to provisioned, you must also set a value for ProvisionedThroughputInMibps. After you create the file system, you can decrease your file system's throughput in Provisioned Throughput mode or change between the throughput modes, with certain time restrictions. For more information, see Specifying throughput with provisioned mode in the Amazon EFS User Guide. Default is bursting.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters
