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.

AccessPointArn

Specifies the Amazon Resource Name (ARN) of the access point that DataSync uses to access the Amazon EFS file system.

Type: String

Length Constraints: Maximum length of 128.

Pattern: ^arn:(aws|aws-cn|aws-us-gov|aws-iso|aws-iso-b):elasticfilesystem:[a-z\-0-9]+:[0-9]{12}:access-point/fsap-[0-9a-f]{8,40}$

Required: No

Ec2Config

Specifies the subnet and security groups DataSync uses to access your Amazon EFS file system.

Type: Ec2Config object

Required: Yes

EfsFilesystemArn

Specifies the ARN for the Amazon EFS file system.

Type: String

Length Constraints: Maximum length of 128.

Pattern: ^arn:(aws|aws-cn|aws-us-gov|aws-iso|aws-iso-b):elasticfilesystem:[a-z\-0-9]*:[0-9]{12}:file-system/fs-.*$

Required: Yes

FileSystemAccessRoleArn

Specifies an Amazon Identity and Access Management (IAM) role that DataSync assumes when mounting the Amazon EFS file system.

Type: String

Length Constraints: Maximum length of 2048.

Pattern: ^arn:(aws|aws-cn|aws-us-gov|aws-iso|aws-iso-b):iam::[0-9]{12}:role/.*$

Required: No

InTransitEncryption

Specifies whether you want DataSync to use Transport Layer Security (TLS) 1.2 encryption when it copies data to or from the Amazon EFS file system.

If you specify an access point using AccessPointArn or an IAM role using FileSystemAccessRoleArn, you must set this parameter to TLS1_2.

Type: String

Valid Values: NONE | TLS1_2

Required: No

Subdirectory

Specifies a mount path for your Amazon EFS file system. This is where DataSync reads or writes data (depending on if this is a source or destination location). By default, DataSync uses the root directory, but you can also include subdirectories.

Note

You must specify a value with forward slashes (for example, /path/to/folder).

Type: String

Length Constraints: Maximum length of 4096.

Pattern: ^[a-zA-Z0-9_\-\+\./\p{Zs}]*$

Required: No

Tags

Specifies the key-value pair that represents a tag that you want to add to the resource. The value can be an empty string. This value helps you manage, filter, and search for your resources. We recommend that you create a name tag for your location.

Type: Array of TagListEntry objects

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Required: No

Response Syntax


{
   "LocationArn": "string"
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

LocationArn

The Amazon Resource Name (ARN) of the Amazon EFS file system location that you create.

Type: String

Length Constraints: Maximum length of 128.

Pattern: ^arn:(aws|aws-cn|aws-us-gov|aws-iso|aws-iso-b):datasync:[a-z\-0-9]+:[0-9]{12}:location/loc-[0-9a-z]{17}$

This exception is thrown when the client submits a malformed request.

HTTP Status Code: 400

Examples

Sample Request

The following example creates a location for an Amazon EFS file system.


{
    "Ec2Config": {
        "SubnetArn": "arn:aws:ec2:us-east-2:11122233344:subnet/subnet-1234567890abcdef1",
        "SecurityGroupArns": [
            "arn:aws:ec2:us-east-2:11122233344:security-group/sg-1234567890abcdef2"
        ]
    },
    "EfsFilesystemArn": "arn:aws:elasticfilesystem:us-east-2:111222333444:file-system/fs-021345abcdef6789",
    "Subdirectory": "/mount/path",
    "Tags": [{
        "Key": "Name",
        "Value": "ElasticFileSystem-1"
    }]
}

Sample Request: Creating a location for a restricted Amazon EFS file system

The following example creates a location for an Amazon EFS file system with restricted access. In this kind of scenario, you might have to specify values for AccessPointArn, FileSystemAccessRoleArn, and InTransitEncryption in your request.


{
    "AccessPointArn": "arn:aws:elasticfilesystem:us-east-2:111222333444:access-point/fsap-1234567890abcdef0",
    "Ec2Config": {
        "SubnetArn": "arn:aws:ec2:us-east-2:111222333444:subnet/subnet-1234567890abcdef1",
        "SecurityGroupArns": [
            "arn:aws:ec2:us-east-2:111222333444:security-group/sg-1234567890abcdef2"
        ]
    },
    "FileSystemAccessRoleArn": "arn:aws:iam::111222333444:role/AwsDataSyncFullAccessNew",
    "InTransitEncryption": "TLS1_2",
    "LocationArn": "arn:aws:datasync:us-east-2:111222333444:location/loc-abcdef01234567890",
    "LocationUri": "efs://us-east-2.fs-021345abcdef6789/",
    "Subdirectory": "/mount/path",
    "Tags": [{
        "Key": "Name",
        "Value": "ElasticFileSystem-1"
    }]
}

Sample Response

A response returns the location ARN of the Amazon EFS file system.


{
  "LocationArn": "arn:aws:datasync:us-east-2:111222333444:location/loc-12abcdef012345678"
}
