--file-share-arn-list (list)

An array containing the Amazon Resource Name (ARN) of each file share to be described.


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


"string" "string" ...

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


NFSFileShareInfoList -> (list)

An array containing a description for each requested file share.


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

NFSFileShareDefaults -> (structure)

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 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 -> (long)

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

OwnerId -> (long)

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.


GatewayARN -> (string)

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

KMSEncrypted -> (boolean)

Set to true to use Amazon S3 server-side encryption with your own AWS KMS key, or false to use a key managed by Amazon S3. Optional.

Valid Values: true | false

KMSKey -> (string)

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 can only be set when KMSEncrypted is true . Optional.

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 file gateway assumes when it accesses the underlying storage.

LocationARN -> (string)

The ARN of the backend storage used for storing file data. A prefix name can be added to the S3 bucket name. It must end with a “/”.

DefaultStorageClass -> (string)

The default storage class for objects put into an Amazon S3 bucket by the file gateway. The default value is S3_INTELLIGENT_TIERING . Optional.


ObjectACL -> (string)

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

ClientList -> (list)

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


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.


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.


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.


FileShareName must be set if an S3 prefix name is set in LocationARN .

CacheAttributes -> (structure)

Refresh cache information.

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. The TTL duration is in seconds.

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