Mounting File Systems From Windows Instances

If you're using Windows platform images, the NFS client is already installed, and the correct user identities are mapped. Skip to step 4.

1. Open Windows PowerShell and run as Administrator:

   1. Go to Start and click the Windows PowerShell icon.

   2. In Windows PowerShell, type the following to run as Administrator:

      Start-Process powershell -Verb runAs

   3. In the User Account Control window, click Yes. A new Administrator: PowerShell window opens. You can close the standard PowerShell window to avoid confusing them.
2. In Administrator: PowerShell, get the NFS client by typing the following:

   Install-WindowsFeature -Name NFS-Client
   Set-ItemProperty HKLM:\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default -Name AnonymousUid -Value 0
   Set-ItemProperty HKLM:\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default -Name AnonymousGid -Value 0
   Stop-Service -Name NfsClnt
   Restart-Service -Name NfsRdr
   Start-Service -Name NfsClnt

   Important
   
   

   If you've set export options for your file system to require clients to connect from a privileged source port (1-1023), then you must set the UseReservedPorts registry key to 1.

   For example:

   
   Set-ItemProperty HKLM:\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default -Name UseReservedPorts -Value 1

   For more information, see Working with NFS Exports and Export Options.

3. Close the Administrator: PowerShell window.

   Open a standard Command Prompt Window:

   1. Click Start, then click Command Prompt.
   Important
   
   NFS file systems mounted as Administrator aren't available to standard users.

4. In the standard Windows Command Line (CMD) window, mount the file system by typing the following:

   mount -o sec=sys 10.x.x.x:/fs-export-path X:

   • Replace 10.x.x.x: with the local subnet IP address assigned to the mount target.
     Note
     
     If the export uses Kerberos authentication, use the fully qualified domain name (FQDN) of the mount target instead of the IP address.

   • Replace fs-export-path with the export path you specified when associating the file system with the mount target.

     Tip
     
     Export path information is available in the Details page of the mount target associated with your file system. See Getting a Mount Target's Details for more information.
     Important
     
     The export path is the path to the file system (relative to the mount target IP address or hostname). If you didn't specify a path when you associated the file system and mount target, then "/" represents the full extent of the mount target. In that case, you must use a "!" when mounting the file system. For example: mount 10.0.0.0:/! X:
   • Replace X with the drive letter of any available drive you want to map the file system to.
   • If the export is using AUTH_SYS alone, the sec option is optional. If the export uses Kerberos authentication, replace sys with krb5, krb5i, or krb5p.
     Note
     
     If an NFS client uses an export which has multiple authentication types, and file system is mounted without specifying sec=<auth_type>, the client should automatically pick the strongest authentication type supported by the export.

5. Write a file to the file system by typing the following. Replace X with the drive letter you used in step 10 and helloworld with your file name.

   X:

   echo > helloworld.txt

6. Verify that you can view the file by typing the following.

   dir

See Troubleshooting Windows NFS Connections for more information about common issues you might encounter.

If you are using Windows platform images, the NFS client is already installed, and the correct user identities are mapped. Skip to step 9.

1. Open Windows PowerShell and run as Administrator:

   1. Go to Start and click the Windows PowerShell icon.

   2. In Windows PowerShell, type the following to run as Administrator:

      Start-Process powershell -Verb runAs

   3. In the User Account Control window, click Yes. A new Administrator: PowerShell window opens. You can close the standard PowerShell window to avoid confusing them.

2. In Administrator: PowerShell, get the NFS client by typing the following:

   Install-WindowsFeature -Name NFS-Client

3. If necessary, restart your system.

4. Open the registry editor (regedit) to map the AnonymousGid and AnonymousUid to the root user.

   Caution
   
   User identity mapping requires changes to your system registry.
   1. Click Windows Search.
   2. Enter regedit in the Search field and press Enter.
   3. Click Yes to allow changes to your device.
   4. Click HKEY_LOCAL_MACHINE. Then, browse to: Software\Microsoft\ClientForNFS\CurrentVersion\Default.

5. Add a new DWORD32 registry entry for AnonymousGid:

   1. Click Edit, and select New DWORD (32 bit) Value.
   2. In the Name field, enter AnonymousGid. Leave the value at 0.

6. Repeat step 5 to add a second DWORD32 registry entry named AnonymousUid with a value of 0.

   Important
   
   

   If you've set export options for your file system to require clients to connect from a privileged source port (1-1023), then you must set the UseReserverdPorts registry key to 1.

   For more information, see Working with NFS Exports and Export Options.

7. Open Windows Command Line (CMD) and run as Administrator:

   1. Go to Start and scroll down to Apps.
   2. In the Windows System section, press Ctrl+Shift and click Command Prompt.

8. In the Windows Command Line (CMD) window, restart the NFS Client by typing the following:

   nfsadmin client stop

   nfsadmin client start

9. Open File Explorer and select This PC. In the Computer tab, select Map network drive.

10. Select the Drive letter that you want to assign to the file system.

11. In the Folder field, enter the following. Replace 10.x.x.x with the local subnet IP address assigned to your mount target, and fs-export-path with the export path you specified when associating the file system with the mount target.

    \\10.x.x.x\fs-export-path

    Tip
    
    IP address and export path information is available in the Details page of the mount target associated with your file system. See Getting a Mount Target's Details for more information.
    Important
    
    The export path is the path to the file system (relative to the mount target IP address or hostname). If you did not specify a path when you associated the file system and mount target, then "\" represents the full extent of the mount target. In that case, you must use a "!" when entering the file system folder path. For example: \\10.0.0.0\!
12. Click the Finish button when complete.

See Troubleshooting Windows NFS Connections for more information about common issues you might encounter.

1. Choose the method you want to use to mount the file system Using Windows Command Prompt or Using Windows File Explorer.
2. Follow the instructions to install the NFS client and add the registry entries for AnonymousGid and AnonymousUid.
3. After the NFS client is installed and registry entries are added, both mounting methods describe how to enter the mount information for the file system. Depending on which method you use, edit the mounting information to append the subdirectory path to the export path:

   1. If you're Using Windows Command Prompt, type the following command (step 4): 

      • Replace 10.x.x.x: with the local subnet IP address assigned to your mount target.

      • Replace fs-export-path with the export path you specified when associating the file system with the mount target.

      • Replace directory-path with the path from the root directory to subdirectory you want to mount.

      mount 10.x.x.x:/fs-export-path/directory-path X:

   2. If you're Using Windows File Explorer, enter the following in the Folder field of the drive letter you want to map the file system to (step 11):

      • Replace 10.x.x.x: with the local subnet IP address assigned to your mount target.

      • Replace fs-export-path with the export path you specified when associating the file system with the mount target.

      • Replace directory-path with the path from the root directory to subdirectory you want to mount.

      \\10.x.x.x\fs-export-path\directory-path
