docs: // CreateNFSFileShare API operation for AWS Storage Gateway.
  //
  // Creates a Network File System (NFS) file share on an existing file gateway.
  // In Storage Gateway, a file share is a file system mount point backed by Amazon
  // S3 cloud storage. Storage Gateway exposes file shares using a NFS interface.
  // This operation is only supported for file gateways.
  //
  // File gateway requires AWS Security Token Service (AWS STS) to be activated
  // to enable you create a file share. Make sure AWS STS is activated in the
  // region you are creating your file gateway in. If AWS STS is not activated
  // in the region, activate it. For information about how to activate AWS STS,
  // see Activating and Deactivating AWS STS in an AWS Region in the AWS Identity
  // and Access Management User Guide.
  //
  // File gateway does not support creating hard or symbolic links on a file share.
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
  //
  // See the AWS API reference guide for AWS Storage Gateway's
  // API operation CreateNFSFileShare for usage and error information.
  //
  // Returned Error Codes:
  //   * ErrCodeInvalidGatewayRequestException "InvalidGatewayRequestException"
  //   An exception occurred because an invalid gateway request was issued to the
  //   service. For more information, see the error and message fields.
  //
  //   * ErrCodeInternalServerError "InternalServerError"
  //   An internal server error has occurred during the request. For more information,
  //   see the error and message fields.
