UpdateSMBFileShare

Updates a Server Message Block (SMB) file share. This operation is only supported for S3 File Gateways.

Note

To leave a file share field unchanged, set the corresponding input field to null.

Important

File gateways require AWS Security Token Service (AWS STS) to be activated to enable you to create a file share. Make sure that AWS STS is activated in the AWS Region you are creating your file gateway in. If AWS STS is not activated in this AWS 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 gateways don't support creating hard or symbolic links on a file share.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

AccessBasedEnumeration

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

Type: Boolean

Required: No

AdminUserList

A list of users or groups in the Active Directory that have administrator rights to the file share. A group must be prefixed with the @ character. Acceptable formats include: DOMAIN\User1, user1, @group1, and @DOMAIN\group1. Can only be set if Authentication is set to ActiveDirectory.

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 100 items.

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: No

AuditDestinationARN

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

Type: String

Length Constraints: Maximum length of 1024.

Required: No

CacheAttributes

Specifies refresh cache information for the file share.

Type: CacheAttributes object

Required: No

CaseSensitivity

The case of an object name in an Amazon S3 bucket. For ClientSpecified, the client determines the case sensitivity. For CaseSensitive, the gateway determines the case sensitivity. The default value is ClientSpecified.

Type: String

Valid Values: ClientSpecified | CaseSensitive

Required: No

DefaultStorageClass

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

Type: String

Length Constraints: Minimum length of 5. Maximum length of 50.

Required: No

EncryptionType

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.

Type: String

Valid Values: SseS3 | SseKms | DsseKms

Required: No

FileShareARN

The Amazon Resource Name (ARN) of the SMB file share that you want to update.

Type: String

Length Constraints: Minimum length of 50. Maximum length of 500.

Required: Yes

FileShareName

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.

A valid SMB file share name cannot contain the following characters: [,],#,;,<,>,:,",\,/,|,?,*,+, or ASCII control characters 1-31.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Required: No

GuessMIMETypeEnabled

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

Type: Boolean

Required: No

InvalidUserList

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: DOMAIN\User1, user1, @group1, and @DOMAIN\group1. Can only be set if Authentication is set to ActiveDirectory.

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 100 items.

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: No

KMSEncrypted

This parameter has been deprecated.

Optional. Set to true to use Amazon S3 server-side encryption with your own AWS 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.

Valid Values: true | false

Type: Boolean

Required: No

KMSKey

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.

Type: String

Length Constraints: Minimum length of 7. Maximum length of 2048.

Required: No

NotificationPolicy

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.

{}

Type: String

Length Constraints: Minimum length of 2. Maximum length of 100.

Pattern: ^\{[\w\s:\{\}\[\]"]*}$

Required: No

ObjectACL

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 private.

Type: String

Required: No

OplocksEnabled

Specifies whether opportunistic locking is enabled for the SMB file share.

Note

Enabling opportunistic locking on case-sensitive shares is not recommended for workloads that involve access to files with the same name in different case.

Valid Values: true | false

Type: Boolean

Required: No

ReadOnly

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

Valid Values: true | false

Type: Boolean

Required: No

RequesterPays

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

Type: Boolean

Required: No

SMBACLEnabled

Set this value to true to enable access control list (ACL) on the SMB file share. Set it to false to map file and directory permissions to the POSIX permissions.

For more information, see Using Windows ACLs to limit SMB file share access in the Amazon S3 File Gateway User Guide.

Valid Values: true | false

Type: Boolean

Required: No

ValidUserList

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

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 100 items.

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: No
