DescribeFileSystems - Amazon FSx

DescribeFileSystems

Returns the description of specific Amazon FSx file systems, if a FileSystemIds value is provided for that file system. Otherwise, it returns descriptions of all file systems owned by your AWS account in the AWS Region of the endpoint that you're calling.

When retrieving all file system descriptions, you can optionally specify the MaxResults parameter to limit the number of descriptions in a response. If more file system descriptions remain, Amazon FSx returns a NextToken value in the response. In this case, send a later request with the NextToken request parameter set to the value of NextToken from the last response.

This operation is used in an iterative process to retrieve a list of your file system descriptions. DescribeFileSystems is called first without a NextTokenvalue. Then the operation continues to be called with the NextToken parameter set to the value of the last NextToken value until a response has no NextToken.

When using this operation, keep the following in mind:

  • The implementation might return fewer than MaxResults file system descriptions while still including a NextToken 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 multicall iteration is unspecified.

Request Syntax

{ "FileSystemIds": [ "string" ], "MaxResults": number, "NextToken": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

FileSystemIds

IDs of the file systems whose descriptions you want to retrieve (String).

Type: Array of strings

Array Members: Maximum number of 50 items.

Length Constraints: Minimum length of 11. Maximum length of 21.

Pattern: ^(fs-[0-9a-f]{8,})$

Required: No

MaxResults

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 FSx returns is the minimum of the MaxResults parameter specified in the request and the service's internal maximum number of items per page.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 2147483647.

Required: No

NextToken

Opaque pagination token returned from a previous DescribeFileSystems operation (String). If a token present, the operation continues the list from where the returning call left off.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: ^(?:[A-Za-z0-9+\/]{4})*(?:[A-Za-z0-9+\/]{2}==|[A-Za-z0-9+\/]{3}=)?$

Required: No
