I’ve since posted a more complete script for a Hyper-V cluster that’s using SMB 3.0 storage.

I am creating and destroying Hyper-V clusters like crazy in the lab at the moment.  And that means I need to script; I don’t want to waste time repeating the same thing over and over in the GUI, wasting valuable time.  Assuming your networking is completed (more to come on scripting that!) and your disk is provisioned/formatted, then the following script will build a cluster for you:

New-Cluster –Name demo-hvc1 –StaticAddress 192.168.1.61 –Node demo-host1, demo-host2

Get-ClusterResource | Where-Object {$_.OwnerGroup –eq “Available Storage”}  | Add-ClusterSharedVolume

(Get-Cluster).SharedVolumeBlockCacheSizeInMB = 512

Get-ClusterSharedVolume *  |  Set-ClusterParameter CSVEnabledBlockCache 1

Get-ClusterSharedVolume  | Stop-ClusterResource

Get-ClusterSharedVolume | Start-ClusterResource

What does the script do?

  1. It creates a new cluster called demo-hvc1 with an IP address of 192.168.1.61 using demo-host1 and demo-host2 as the nodes.
  2. It finds all available disk and converts it to CSV volumes.
  3. Then it configures CSV cache to use 512 MB RAM
  4. Every CSV is configured to use CSV cache
  5. The CSVs are stopped
  6. The CSVs are restarted so they can avail of CSV cache

The script doesn’t do a validation.  My setup is pretty static so no validation is required.  BTW, for the VMLimited fanboys out there who moan about time to deploy Hyper-V, my process (networking included) builds the cluster in probably around 30-40 seconds.

  1. Get-ClusterResource | Where-Object {$_.OwnerGroup –eq “Available Storage”}
    can also be done as
    Get-ClusterGroup “Available Storage” | Get-ClusterResource
    The first one gets all resources in the cluster and filters the ones in the Available Storage Group, the second gets the Available Storage group and then just gets the resources in that group. Something to keep in mind when managing clusters with large amounts of resources.
