Creating NFS share on Windows Server 2003…

July 2nd, 2009

In this post, I’ll talk through how to create an NFS Share in Windows 2003, I’ll then follow it up with a quick post about how to connect to this NFS Share from within your ESXi host.

This post is largely similar to The musings of an IT Consultant: backups VMware ESXi blog, Raj also has a blog called The World Runs on Technology – both of which are excellent – you should check them out.

Stage 4 – setting up NFS Share on Windows Server 2003.

1. Using your FTP client, grab a copy of the following two files from your ESXi host and put them somewhere safe:

/ etc /passwd
/ etc /group

2. Now, download Windows Services for Unix 3.5 from here, and install onto your Windows 2003 server, requires reboot.

3. During install ensure you select the Server for NFS and User Mapping components during the install.

4. In the user mapping section, choose Local User Name Mapping Server and choose Password and Group files

5. In the user name mapping screen, select the passwd and group files that you ftp’s earlier.

6. Reboot your 2003 server and then launch into the MMC (Start -> Run -> MMC)

7. You now need to add the Services for Unix snap-in.  (File -> Add/Remove Snap In -> Add)

8. Now, chose User Name Mapping on the left hand side, then select the MAPS section in the right hand side

9. Make sure ‘simple maps’ is checked and then click on show user maps – then list both the Windows and Unix users.

10. Your best option here is to Map your Administrator account to the unix root user – then Apply your settings. You’re done.

Now, on your 2003 machine, create a new folder called, ‘Backup’ for example. Right click on this folder and chose properties. You’ll notice that you have a new tab – called ‘NFS Sharing’. In this tab we can set the share name as Backup. In the permissions section, allow root ‘read-write’ access.

That’s it for setting up the share, you now have a storage area in windows that your ESXi can communicate with. All that’s left, is to point your ESXi host at the new share. So, from the VMWare Infrastructure Client – Go to the ‘Configuration’ tab and then chose ‘Storage’ and then ‘Add Storage’ (which is on the far right)

Here, simply enter the details of the NFS Share you just created and the Share Name etc, like so:

Ok, you’re done. In the next post, I’ll be showing you how to automate ESXi snapshot backups through a combination of Scheduled Tasks, and plink.
