update-location-nfs

Description

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 .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  update-location-nfs
--location-arn <value>
[--subdirectory <value>]
[--on-prem-config <value>]
[--mount-options <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--location-arn (string)

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

--subdirectory (string)

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 Snowcone device, see NFS Server on 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.

--on-prem-config (structure)

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

AgentArns -> (list)

ARNs of the agents to use for an NFS location.

(string)

Shorthand Syntax:

AgentArns=string,string

JSON Syntax:

{
  "AgentArns": ["string", ...]
}

--mount-options (structure)

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

Version -> (string)

The specific NFS version that you want DataSync to use to mount your NFS share. If the server refuses to use the version specified, the sync will fail. If you don't specify a version, DataSync defaults to AUTOMATIC . That is, DataSync automatically selects a version based on negotiation with the NFS server.

You can specify the following NFS versions:

  • **NFSv3 ** - stateless protocol version that allows for asynchronous writes on the server.
  • **NFSv4.0 ** - stateful, firewall-friendly protocol version that supports delegations and pseudo file systems.
  • **NFSv4.1 ** - stateful protocol version that supports sessions, directory delegations, and parallel data processing. Version 4.1 also includes all features available in version 4.0.

Shorthand Syntax:

Version=string

JSON Syntax:

{
  "Version": "AUTOMATIC"|"NFS3"|"NFS4_0"|"NFS4_1"
}

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.
