Server 2012 R2 Failover Cluster

Running Windows Server 2012 R2 Datacenter with Hyper V role installed.  I have created a RAID 5 with six 2TB hard drives for total of 8.95TB usable.  I am using Windows Storage Spaces to configure my storage infrastructure.  I created a storage pool that is 8.95TB and then created a virtual disk with size of 4TB and assigned it a drive letter E. I configured this on two physical servers with identical hardware.

When I try to create a Windows failover cluster and begin the validation process my virtual disk is detached and validation fails.

Cannot get past this step and not sure if I am missing a step or doing something wrong.

Would appreciate some ideas on how to resolve this issue.

1) Don't use RAID and storage spaces together. Pick one or the other.
2) a hyper-V cluster requires shared storage. You can't create/validate a cluster if you only have servers with locally attached disks, even if they are configured the same,

I am using Starwind VSAN software to create the shared storage.

How would I expose the JBOD to Windows Server 2012?
Have you presented the Starwind vSAN iSCSI IP Address to both nodes ?
then you should be able to re-scan, and see the iSCSI disks?
I do see the iscsi disks, but the drive where I save the Starwind Images and LSFS files disappears when I do cluster validation on Windows 2012 box.

I fixed the problem by creating a new volume on the RAID 10 presented by windows disk management.
