Creates a Server Message Block (SMB) file share on an existing S3 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 an SMB interface. This operation is only supported for S3 File Gateways.

S3 File Gateways require Security Token Service (Amazon Web Services STS) to be activated to enable you to create a file share. Make sure that Amazon Web Services STS is activated in the Amazon Web Services Region you are creating your S3 File Gateway in. If Amazon Web Services STS is not activated in this Amazon Web Services Region, activate it. For information about how to activate Amazon Web Services STS, see Activating and deactivating Amazon Web Services STS in an Amazon Web Services Region in the Identity and Access Management User Guide.

File gateways don't support creating hard or symbolic links on a file share.

X-Amz-Target'StorageGateway_20130630.CreateSMBFileShare' required

Request body

ClientTokenstring required

A unique string value that you supply that is used by S3 File Gateway to ensure idempotent file share creation.

GatewayARNstring required

The ARN of the S3 File Gateway on which you want to create a file share.

KMSEncryptedboolean
<p>Set to <code>true</code> to use Amazon S3 server-side encryption with your own KMS key, or <code>false</code> to use a key managed by Amazon S3. Optional.</p> <p>Valid Values: <code>true</code> | <code>false</code> </p>
KMSKeystring

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 <code>KMSEncrypted</code> is <code>true</code>. Optional.

Rolestring required

The ARN of the Identity and Access Management (IAM) role that an S3 File Gateway assumes when it accesses the underlying storage.

LocationARNstring required
<p>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 (/).</p> <note> <p>You can specify LocationARN as a bucket ARN, access point ARN or access point alias, as shown in the following examples.</p> <p>Bucket ARN:</p> <p> <code>arn:aws:s3:::my-bucket/prefix/</code> </p> <p>Access point ARN:</p> <p> <code>arn:aws:s3:region:account-id:accesspoint/access-point-name/prefix/</code> </p> <p>If you specify an access point, the bucket policy must be configured to delegate access control to the access point. For information, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-points-policies.html#access-points-delegating-control">Delegating access control to access points</a> in the <i>Amazon S3 User Guide</i>.</p> <p>Access point alias:</p> <p> <code>test-ap-ab123cdef4gehijklmn5opqrstuvuse1a-s3alias</code> </p> </note>
DefaultStorageClassstring
<p>The default storage class for objects put into an Amazon S3 bucket by the S3 File Gateway. The default value is <code>S3_STANDARD</code>. Optional.</p> <p>Valid Values: <code>S3_STANDARD</code> | <code>S3_INTELLIGENT_TIERING</code> | <code>S3_STANDARD_IA</code> | <code>S3_ONEZONE_IA</code> </p>
ObjectACL'private' | 'public-read' | 'public-read-write' | 'authenticated-read' | 'bucket-owner-read' | 'bucket-owner-full-control' | 'aws-exec-read'

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

ReadOnlyboolean
<p>A value that sets the write status of a file share. Set this value to <code>true</code> to set the write status to read-only, otherwise set to <code>false</code>.</p> <p>Valid Values: <code>true</code> | <code>false</code> </p>
GuessMIMETypeEnabledboolean
<p>A value that enables guessing of the MIME type for uploaded objects based on file extensions. Set this value to <code>true</code> to enable MIME type guessing, otherwise set to <code>false</code>. The default value is <code>true</code>.</p> <p>Valid Values: <code>true</code> | <code>false</code> </p>
RequesterPaysboolean
<p>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 <code>true</code>, the requester pays the costs; otherwise, the S3 bucket owner pays. However, the S3 bucket owner always pays the cost of storing data.</p> <note> <p> <code>RequesterPays</code> 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.</p> </note> <p>Valid Values: <code>true</code> | <code>false</code> </p>
SMBACLEnabledboolean
<p>Set this value to <code>true</code> to enable access control list (ACL) on the SMB file share. Set it to <code>false</code> to map file and directory permissions to the POSIX permissions.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/storagegateway/latest/userguide/smb-acl.html">Using Microsoft Windows ACLs to control access to an SMB file share</a> in the <i>Storage Gateway User Guide</i>.</p> <p>Valid Values: <code>true</code> | <code>false</code> </p>
AccessBasedEnumerationboolean

The files and folders on this share will only be visible to users with read access.

AdminUserListUserListUser[]
<p>A list of users or groups in the Active Directory that will be granted administrator privileges on the file share. These users can do all file operations as the super-user. Acceptable formats include: <code>DOMAIN\User1</code>, <code>user1</code>, <code>@group1</code>, and <code>@DOMAIN\group1</code>.</p> <important> <p>Use this option very carefully, because any user in this list can do anything they like on the file share, regardless of file permissions.</p> </important>
ValidUserListUserListUser[]

A list of users or groups in the Active Directory that are allowed to access the file <a href=""/> share. A group must be prefixed with the @ character. Acceptable formats include: <code>DOMAIN\User1</code>, <code>user1</code>, <code>@group1</code>, and <code>@DOMAIN\group1</code>. Can only be set if Authentication is set to <code>ActiveDirectory</code>.

InvalidUserListUserListUser[]

A list of users or groups in the Active Directory that are not allowed to access the file share. A group must be prefixed with the @ character. Acceptable formats include: <code>DOMAIN\User1</code>, <code>user1</code>, <code>@group1</code>, and <code>@DOMAIN\group1</code>.

NotificationPolicystring
<p>The notification policy of the file share. <code>SettlingTimeInSeconds</code> controls the number of seconds to wait after the last point in time a client wrote to a file before generating an <code>ObjectUploaded</code> 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.</p> <note> <p> <code>SettlingTimeInSeconds</code> has no effect on the timing of the object uploading to Amazon S3, only the timing of the notification.</p> </note> <p>The following example sets <code>NotificationPolicy</code> on with <code>SettlingTimeInSeconds</code> set to 60.</p> <p> <code>{\"Upload\": {\"SettlingTimeInSeconds\": 60}}</code> </p> <p>The following example sets <code>NotificationPolicy</code> off.</p> <p> <code>{}</code> </p>

BucketRegionstring
<p>Specifies the Region of the S3 bucket where the SMB file share stores files.</p> <note> <p>This parameter is required for SMB 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.</p> </note>
OplocksEnabledboolean
