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 Amazon Web Services account in the Amazon Web Services 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 body

FileSystemIdsFileSystemId[]

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

MaxResultsinteger

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 <code>MaxResults</code> parameter specified in the request and the service's internal maximum number of items per page.

NextTokenstring

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

Response

Success

NextTokenstring

Present if there are more file systems than returned in the response (String). You can use the <code>NextToken</code> value in the later request to fetch the descriptions.
