CreateLocationNfs

Creates an endpoint for a Network File System (NFS) file system.

Request Syntax

{
   "MountOptions": { 
      "Version": "string"
   },
   "OnPremConfig": { 
      "AgentArns": [ "string" ]
   },
   "ServerHostname": "string",
   "Subdirectory": "string",
   "Tags": [ 
      { 
         "Key": "string",
         "Value": "string"
      }
   ]
}

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.

MountOptions

The NFS mount options that DataSync can use to mount your NFS share.

Type: NfsMountOptions object

Required: No

OnPremConfig

Contains a list of Amazon Resource Names (ARNs) of agents that are used to connect to an NFS server.

Type: OnPremConfig object

Required: Yes

ServerHostname

The name of the NFS server. This value is the IP address or Domain Name Service (DNS) name of the NFS server. An agent that is installed on-premises uses this host name to mount the NFS server in a network.

Note

This name must either be DNS-compliant or must be an IP version 4 (IPv4) address.

Type: String

Length Constraints: Maximum length of 255.

Pattern: ^(([a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z0-9\-]*[A-Za-z0-9])$

Required: Yes

Subdirectory

The subdirectory in the NFS file system that is used to read data from the NFS source location or write data to the NFS destination. The NFS path should be a path that's exported by the NFS server, or a subdirectory of that path. The path should be such that it can be mounted by other NFS clients in your network.

To see all the paths exported by your NFS server. run "showmount -e nfs-server-name" from an NFS client that has access to your server. You can specify any directory that appears in the results, and any subdirectory of that directory. Ensure that the NFS export is accessible without Kerberos authentication.

To transfer all the data in the folder you specified, DataSync needs to have permissions to read all the data. To ensure this, either configure the NFS export with no_root_squash, or ensure that the permissions for all of the files that you want DataSync allow read access for all users. Doing either enables the agent to read the files. For the agent to access directories, you must additionally enable all execute access.

For information about NFS export configuration, see 18.7. The /etc/exports Configuration File in the Red Hat Enterprise Linux documentation.

Type: String

Length Constraints: Maximum length of 4096.

Pattern: ^[a-zA-Z0-9_\-\./]+$

Required: Yes

Tags

The key-value pair that represents the tag that you want to add to the location. The value can be an empty string. We recommend using tags to name your resources.

Type: Array of TagListEntry objects

Array Members: Minimum number of 0 items. Maximum number of 55 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 source NFS file system location that is created.

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}$

Errors

For information about the errors that are common to all actions, see Common Errors.

InternalException

This exception is thrown when an error occurs in the AWS DataSync service.

HTTP Status Code: 500

InvalidRequestException

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

HTTP Status Code: 400

Examples

Example

The following example creates an endpoint for a NFS file system using the specified NFS version as a mount option.

Sample Request

{
  "MountOptions": {
     "Version": : "NFS4_0"
     },
  "OnPremConfig": {
    "AgetArn": [ "arn:aws:datasync:us-east-2:111222333444:agent/agent-0b0addbeef44b3nfs" ]
          },
          
           "ServerHostname": "MyServer@amazon.com",
           "Subdirectory": "/MyFolder",
           "Tags": [
              {
                "Key": "Name",
                "Value": "ElasticFileSystem-1"
              }
           ]
}

Example

The response returns the Amazon Resource Name (ARN) of the NFS location.

Sample Response

{
  "LocationArn": "arn:aws:datasync:us-east-2:111222333444:location/loc-07db7abfc326c50aa"
}
