I created a test cluster in Windows 2003 running on Virtual Box. The virtual disk to be used as a cluster resource has been changed to type shereable using VBoxManage command line utility. On that disk I created a primary partition and mounted it on one server as drive D. The cluster has been created successfully using Majority Node Set for quorum.

When adding drive D as a resource it failes and becomes unavailible in explorer, removing the disk from the resources makes it availible again.

To eliminate the Shereable vdi disk as the cause I created a new virtual disk on a new virtual SCSI controller, which does not have Shereable for it's Type. Still when added as a cluster resource it fails and becomes unavailible.

Last I checked, VirtualBox virtual disks are not supported for Cluster Services. You should use a third VM to present this disk as iSCSI rather than as a shared vdisk.

I think you're right, I'll implement it using ISCSI and FreeNAS, been looking into it as I read your answer. Thanks. – Dean May 5 '12 at 19:45
It also brings me to the thought that it's about time to ditch VirtualBox... – Dean May 5 '12 at 19:46
I assumed that this was in a test environment. I absolutely would not let VirtualBox anywhere near a production environment. Both ESXi and Hyper-V are free and work fine in smaller installations without the more expensive features from the paid add-ons. – MDMarra May 5 '12 at 19:48
It's a test environment, I agree with you on what you said about VirtualBox. – Dean May 5 '12 at 20:04
