Description

The Set-NfsServerConfig cmdlet changes the configuration settings for an existing Network File System (NFS) server.

For some changes to take effect, you must restart Services for NFS. The cmdlet prompts you to restart if necessary.

Examples

Example 1: Set a grace period on a local NFS server

PS C:\> Set-NfsServerConfiguration -NlmGracePeriodSec 45 -GracePeriodSec 240

This command sets the grace period for the NLM protocol to 45 seconds and sets the grace period for NFS v4.1 to 240 seconds on a local NFS server.

Example 2: Set NFS versions on a local NFS server

PS C:\> Set-NfsServerConfiguration -EnableNfsv2 $False -EnableNfsv4 $True -EnableNfsv3 $True

This command disables versions 2 and 3 of the NFS protocol and enables NFS v4.1 on a local NFS server.

Optional Parameters

-AlwaysOpenByName

Specifies whether an NFS server opens files and directories by name, instead of opening by file ID. You can enable this setting for compatibility with filter drivers that intercept requests for opening files and directories by file name, or for applications that rely on directory change notifications to work with NFS shares.

The default value is $False. By default, an NFS server opens files and directories by ID to improve performance.

Type: Boolean
Aliases: OpenByName
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-AsJob

Indicates that this cmdlet runs the command as a background job on a remote computer. Use this parameter to run commands that take an extensive time to finish.

When you use the AsJob parameter, the command returns an object that represents the job, and then displays the command prompt. You can continue to work in the session while the job finishes. To manage the job, use the Job cmdlets. To get the job results, use the Receive-Job cmdlet.

The AsJob parameter resembles using the Invoke-Command cmdlet to run a Start-Job command remotely. However, with AsJob , the job is created on the local computer, even though the job runs on a remote computer, and the results of the remote job are automatically returned to the local computer.

For more information about Windows PowerShell background jobs, see about_Jobs and about_Remote_Jobs .
