Response Structure

• (dict) –

  DescribeNFSFileSharesOutput

  • NFSFileShareInfoList (list) –

    An array containing a description for each requested file share.

    • (dict) –

      The Unix file permissions and ownership information assigned, by default, to native S3 objects when an S3 File Gateway discovers them in S3 buckets. This operation is only supported in S3 File Gateways.

      • NFSFileShareDefaults (dict) –

        Describes Network File System (NFS) file share default values. Files and folders stored as Amazon S3 objects in S3 buckets don’t, by default, have Unix file permissions assigned to them. Upon discovery in an S3 bucket by Storage Gateway, the S3 objects that represent files and folders are assigned these default Unix permissions. This operation is only supported for S3 File Gateways.

        • FileMode (string) –

          The Unix file mode in the form “nnnn”. For example, 0666 represents the default file mode inside the file share. The default value is 0666.

        • DirectoryMode (string) –

          The Unix directory mode in the form “nnnn”. For example, 0666 represents the default access mode for all directories inside the file share. The default value is 0777.

        • GroupId (integer) –

          The default group ID for the file share (unless the files have another group ID specified). The default value is nfsnobody.

        • OwnerId (integer) –

          The default owner ID for files in the file share (unless the files have another owner ID specified). The default value is nfsnobody.

      • FileShareARN (string) –

        The Amazon Resource Name (ARN) of the file share.

      • FileShareId (string) –

        The ID of the file share.

      • FileShareStatus (string) –

        The status of the file share.

        Valid Values: CREATING | UPDATING | AVAILABLE | DELETING

      • GatewayARN (string) –

        The Amazon Resource Name (ARN) of the gateway. Use the ListGateways operation to return a list of gateways for your account and Amazon Web Services Region.

      • EncryptionType (string) –

        A value that specifies the type of server-side encryption that the file share will use for the data that it stores in Amazon S3.

        Note

        We recommend using EncryptionType instead of KMSEncrypted to set the file share encryption method. You do not need to provide values for both parameters.

        If values for both parameters exist in the same request, then the specified encryption methods must not conflict. For example, if EncryptionType is SseS3, then KMSEncrypted must be false. If EncryptionType is SseKms or DsseKms, then KMSEncrypted must be true.

      • KMSEncrypted (boolean) –

        Optional. Set to true to use Amazon S3 server-side encryption with your own KMS key (SSE-KMS), or false to use a key managed by Amazon S3 (SSE-S3). To use dual-layer encryption (DSSE-KMS), set the EncryptionType parameter instead.

        Note

        We recommend using EncryptionType instead of KMSEncrypted to set the file share encryption method. You do not need to provide values for both parameters.

        If values for both parameters exist in the same request, then the specified encryption methods must not conflict. For example, if EncryptionType is SseS3, then KMSEncrypted must be false. If EncryptionType is SseKms or DsseKms, then KMSEncrypted must be true.

        Valid Values: true | false

      • KMSKey (string) –

        Optional. The Amazon Resource Name (ARN) of a symmetric customer master key (CMK) used for Amazon S3 server-side encryption. Storage Gateway does not support asymmetric CMKs. This value must be set if KMSEncrypted is true, or if EncryptionType is SseKms or DsseKms.

      • Path (string) –

        The file share path used by the NFS client to identify the mount point.

      • Role (string) –

        The ARN of the IAM role that an S3 File Gateway assumes when it accesses the underlying storage.

      • LocationARN (string) –

        A custom ARN for the backend storage used for storing data for file shares. It includes a resource ARN with an optional prefix concatenation. The prefix must end with a forward slash (/).

        Note

        You can specify LocationARN as a bucket ARN, access point ARN or access point alias, as shown in the following examples.

        Bucket ARN:

        arn:aws:s3:::amzn-s3-demo-bucket/prefix/

        Access point ARN:

        arn:aws:s3:region:account-id:accesspoint/access-point-name/prefix/

        If you specify an access point, the bucket policy must be configured to delegate access control to the access point. For information, see Delegating access control to access points in the Amazon S3 User Guide.

        Access point alias:

        test-ap-ab123cdef4gehijklmn5opqrstuvuse1a-s3alias

      • DefaultStorageClass (string) –

        The default storage class for objects put into an Amazon S3 bucket by the S3 File Gateway. The default value is S3_STANDARD. Optional.

        Valid Values: S3_STANDARD | S3_INTELLIGENT_TIERING | S3_STANDARD_IA | S3_ONEZONE_IA

      • ObjectACL (string) –

        A value that sets the access control list (ACL) permission for objects in the S3 bucket that an S3 File Gateway puts objects into. The default value is private.

      • ClientList (list) –

        The list of clients that are allowed to access the S3 File Gateway. The list must contain either valid IP addresses or valid CIDR blocks.

        • (string) –

      • Squash (string) –

        The user mapped to anonymous user. Valid options are the following:

        • RootSquash: Only root is mapped to anonymous user.

        • NoSquash: No one is mapped to anonymous user.

        • AllSquash: Everyone is mapped to anonymous user.

      • ReadOnly (boolean) –

        A value that sets the write status of a file share. Set this value to true to set the write status to read-only, otherwise set to false.

        Valid Values: true | false

      • GuessMIMETypeEnabled (boolean) –

        A value that enables guessing of the MIME type for uploaded objects based on file extensions. Set this value to true to enable MIME type guessing, otherwise set to false. The default value is true.

        Valid Values: true | false

      • RequesterPays (boolean) –

        A value that sets who pays the cost of the request and the cost associated with data download from the S3 bucket. If this value is set to true, the requester pays the costs; otherwise, the S3 bucket owner pays. However, the S3 bucket owner always pays the cost of storing data.

        Note

        RequesterPays is a configuration for the S3 bucket that backs the file share, so make sure that the configuration on the file share is the same as the S3 bucket configuration.

        Valid Values: true | false

      • Tags (list) –

        A list of up to 50 tags assigned to the NFS file share, sorted alphabetically by key name. Each tag is a key-value pair. For a gateway with more than 10 tags assigned, you can view all tags using the ListTagsForResource API operation.

        • (dict) –

          A key-value pair that helps you manage, filter, and search for your resource. Allowed characters: letters, white space, and numbers, representable in UTF-8, and the following characters: + - = . _ : /.

          • Key (string) –

            Tag key. The key can’t start with aws:.

          • Value (string) –

            Value of the tag key.

      • FileShareName (string) –

        The name of the file share. Optional.

        Note

        FileShareName must be set if an S3 prefix name is set in LocationARN, or if an access point or access point alias is used.

      • CacheAttributes (dict) –

        Refresh cache information for the file share.

        • CacheStaleTimeoutInSeconds (integer) –

          Refreshes a file share’s cache by using Time To Live (TTL). TTL is the length of time since the last refresh after which access to the directory would cause the file gateway to first refresh that directory’s contents from the Amazon S3 bucket or Amazon FSx file system. The TTL duration is in seconds.

          Valid Values:0, 300 to 2,592,000 seconds (5 minutes to 30 days)

      • NotificationPolicy (string) –

        The notification policy of the file share. SettlingTimeInSeconds controls the number of seconds to wait after the last point in time a client wrote to a file before generating an ObjectUploaded notification. Because clients can make many small writes to files, it’s best to set this parameter for as long as possible to avoid generating multiple notifications for the same file in a small time period.

        Note

        SettlingTimeInSeconds has no effect on the timing of the object uploading to Amazon S3, only the timing of the notification.

        This setting is not meant to specify an exact time at which the notification will be sent. In some cases, the gateway might require more than the specified delay time to generate and send notifications.

        The following example sets NotificationPolicy on with SettlingTimeInSeconds set to 60.

        {\"Upload\": {\"SettlingTimeInSeconds\": 60}}

        The following example sets NotificationPolicy off.

        {}

      • VPCEndpointDNSName (string) –

        Specifies the DNS name for the VPC endpoint that the NFS file share uses to connect to Amazon S3.

        Note

        This parameter is required for NFS file shares that connect to Amazon S3 through a VPC endpoint, a VPC access point, or an access point alias that points to a VPC access point.

      • BucketRegion (string) –

        Specifies the Region of the S3 bucket where the NFS file share stores files.

        Note

        This parameter is required for NFS file shares that connect to Amazon S3 through a VPC endpoint, a VPC access point, or an access point alias that points to a VPC access point.

      • AuditDestinationARN (string) –

        The Amazon Resource Name (ARN) of the storage used for audit logs.
