Adding File Server Role to in-guest cluster

Windows Server 2012 R2 with Update.

We already have a Hyper-V cluster that is working fine.  We created an in-guest SQL Server 2014 cluster on top of the Hyper-V cluster and that is working fine.  We decided to add the File Server role to the SQL Server in-guest cluster.  The in-guest cluster has three storage volumes:

1.  Cluster Disk 1 - Cluster Shared Volume used to store the SQL Server database only.
2.  Cluster Disk 2 - Disk Witness in Quorum.
3.  Cluster Disk 3 - Cluster Shared Volume currently Unused

When I run through the wizard to add the File Server role, I choose  "File Server for General Use" I then choose an IP address and give it a name.  The next step is to choose storage and the wizard says No Storage is Available.  

Question:  How can I make the wizard use Cluster Disk 3?

Thank you for your help.

Is it such a good idea as to run an additional role on the guest SQL cluster?

For file services, a cluster within a cluster really doesn't make any sense? What would be accomplished by this?

I suggest setting up an HA VM that is dedicated to the file services role on the Hyper-V cluster.

Unfortunately, those are the requirements.  From a licensing standpoint and others, we have to be frugal.  Setting up another in-guest cluster just for File Server role has been shot down for now.

James,

You already have a cluster on Hyper-V. That's your failover protection for an HA VM that hosts the file services, and other roles. I am not suggesting to set up another cluster when one is already there and ready to host workloads.

Setting up a VM on the Hyper-V cluster just for the file services role would still consume another license - which we don't have (we are using Windows Server Standard for all the licensing).  Further, a single VM is HA when it comes to hardware failures, but not software failures (e.g. bad patch).  That's why we wanted to utilized an existing in-guest cluster.

James
James,

I'm not getting the point?

A cluster is a cluster. If a patch toasts one of the Hyper-V hosts the VMs saddle up on the other host.

Is this what the goal is? TechNet: Windows Server 2012 Continuous Availability File Server feature

There's a How-To in there to get things going via Failover Cluster Manager.

Would we do it on an already deployed SQL cluster setup? Flat out no.

Point of Clarification: In a cluster setting 2 VMs running on two nodes require two Windows Server Standard licenses (1:2 across two nodes). 4 VMs running on a two node Hyper-V cluster would require four licenses (1:2 across two nodes).

EDIT: License clarification assumes one or two CPUs per physical host.

So what happens when a bad patch toasts the VM?  At that point you are still down.  You would have to have two VM's in an in-guest cluster on top of the Hyper-V cluster for true HA - which we already have it's just running SQL also.

Regarding licensing, you are asking me to set up one - two more VM's and we are out of licenses.

I'm of the same mind.  I really don't want to have an already running SQL Server in-guest cluster running another role.  I think I'm going to go to the higher-ups and just tell them like it is.  Surely they can afford $1600 for two more Standard licenses.

James
James,

If the server setup is recent an OEM license pair may be had for less cost.

Thanks for the points eh! :)

Wait, how many points did you get??  I don't see anywhere on this thing to allocate points!

I ALWAYS post all questions with 500 points.  At least, that's how things were done on the old interface (500 was the default).  Not quite use to this one.

James
I see 500 points on my end. The new UI has been modified at least twice in the last year or so? I've hopelessly lost my cheese ... ;)
