Synopsis

Invokes the DescribeFileSystems operation against Amazon Elastic File System.

Syntax

Get-EFSFileSystem
-FileSystemId <String>
-CreationToken <String>
-Marker <String>
-MaxItem <Int32>

Description

Returns the description of a specific Amazon EFS file system if either the file system CreationToken or the FileSystemId is provided. Otherwise, it returns descriptions of all file systems owned by the caller's AWS account in the AWS Region of the endpoint that you're calling. When retrieving all file system descriptions, you can optionally specify the MaxItems parameter to limit the number of descriptions in a response. If more file system descriptions remain, Amazon EFS returns a NextMarker, an opaque token, in the response. In this case, you should send a subsequent request with the Marker request parameter set to the value of NextMarker. To retrieve a list of your file system descriptions, this operation is used in an iterative process, where DescribeFileSystems is called first without the Marker and then the operation continues to call it with the Marker parameter set to the value of the NextMarker from the previous response until the response has no NextMarker. The implementation may return fewer than MaxItems file system descriptions while still including a NextMarker value. The order of file systems returned in the response of one DescribeFileSystems call and the order of file systems returned across the responses of a multi-call iteration is unspecified. This operation requires permissions for the elasticfilesystem:DescribeFileSystems action.

This operation automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output.

Parameters

-CreationToken <String>
(Optional) Restricts the list to the file system with this creation token (String). You specify a creation token when you create an Amazon EFS file system.
Required?False
Position?Named
Accept pipeline input?False
-FileSystemId <String>
(Optional) ID of the file system whose description you want to retrieve (String).
Required?False
Position?1
Accept pipeline input?True (ByValue, )
-Marker <String>
(Optional) Opaque pagination token returned from a previous DescribeFileSystems operation (String). If present, specifies to continue the list from where the returning call had left off.
Required?False
Position?Named
Accept pipeline input?False
-MaxItem <Int32>
(Optional) Specifies the maximum number of file systems to return in the response (integer). This parameter value must be greater than 0. The number of items that Amazon EFS returns is the minimum of the MaxItems parameter specified in the request and the service's internal maximum number of items per page.
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

You can pipe a String object to this cmdlet for the FileSystemId parameter.

Outputs

This cmdlet returns a collection of FileSystemDescription objects. The service call response (type Amazon.ElasticFileSystem.Model.DescribeFileSystemsResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack. Additionally, the following properties are added as Note properties to the service response type instance for the cmdlet entry in the $AWSHistory stack: Marker (type System.String), NextMarker (type System.String)
