Updates some of the parameters of a previously created location for Network File System (NFS) access. For information about creating an NFS location, see Creating a location for NFS.

Request Syntax

{ "LocationArn": "string", "MountOptions": { "Version": "string" }, "OnPremConfig": { "AgentArns": [ "string" ] }, "Subdirectory": "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.

LocationArn

The Amazon Resource Name (ARN) of the NFS location to update.

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}$

Required: Yes

MountOptions

Represents the mount options that are available for DataSync to access an NFS location.

Type: NfsMountOptions object

Required: No

OnPremConfig

A list of Amazon Resource Names (ARNs) of agents to use for a Network File System (NFS) location.

Type: OnPremConfig object

Required: No

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

If you are copying data to or from your AWS Snowcone device, see NFS Server on AWS Snowcone for more information.

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_\-\+\./\(\)\p{Zs}]+$
