Clustering FileServer on Windows 2012 Step by Step.   12 comments

Clustering with file server is easy but I see a lot of problems that are basically configuration errors or misconfiguration. and this is all in windows 2012.

Adding the fileserver in as an resource simple steps.

I use a simple file server for general usage.



File server netbios name and IP


the cluster resource is ready to go and online.


Now we are ready to create a file share on the new file server.




choose Add file share and a new wizard opens to create a new share


and here the window shows you new items


Give the share name and the folder will be created if the folder is not present.


access based enumeration is here in the menu this is a great feature

more info you can find here :


see the access rights on the share


The share creation is completed

Open the shared folder local or by UNC path.

that’s all folks. and see what windows 2012 can bring to you .

  1. Thanks for this article and especially for the earlier article on performance implications of ABE. I wondered if those findings still apply (approximately) to server 2012? We have one large (~32TB data) clustered users filestore with ABE enabled. Top level has 10,500 folders. We also have a smaller volume (~14TB data) with about 11,500 users and ABE enabled. There are more than a billion files in the largest store. We are in the process of splitting this up (it’s like this for historical reasons). However, in the meantime how much do you think ABE might affect performance with these kinds of figures?

    Many thanks,


    • it is always hard to tell it there is performance impact.

      but with a lot of files in one folder. splitting up is always faster for your storage so ABE will not be an issue is my guess

      • Thank you. We have about ~150 users using a third of the space. We’ll move those so we can shrink the volume size somewhat to allow to do proper maintenance tasks and then look at splitting further. Would you be able to suggest a recommended number per volume? (given that we have ~10,000 users on the one I’m concerned with).

  2. You can do some performance testing , see how the read/write is on the current disk with the 10k users if you move or split this folder the load is different if it is on the same spindels more seeks etc.

    the more files in a folder the more the client needs to seek or wait. but all depends on the san. if this is fast than you are good.
    as it runs now already so you are fine. if possible keep folders to 500k files if possible.

    let me know when you are done and how the performance is 😉

  3. I have setup my cluster very similarly to what is posted here. The only exception is that I did not enable continuously available shares. I am seeing some strange issues with files where if I access them from the UNC (\\cluster\share\file) I have roughly a 20 second delay in opening or receiving a context menu when right clicking. If I access the share through DFS, which maps to the same UNC, performance is normal. The LUNs are direct attached iSCSI. The servers are using multiple 10Gbe NICs, and we have a NIC team to the LUN. RSS is enabled. Thank you for any guidance.

  4. Thanks for the article…. I am going to setup clustered file server over two hyper-V VMs. Please let me know if any considerations I should take for clustering file server on a two clustered VMs.

    Thanks in advance for your help….

  5. Good writeup, I am normal visitor of ones blog, maintain up the excellent operate, and It’s going to be a regular visitor for a lengthy time. dbdfgefkggeb

  6. I have a cluster up and running with Hyper-V. I’d like to add a File Server Cluster role. Can I use the same storage as I’ve already assigned to Hyper-V or does it require exclusive access?

    • It is not best practice to mix any fileserver role with Hyper-V but you can mix them but think about the option to build a virtual File cluster on top of the Hyper-v server as a VM. this doubles your uptime of the file server.
