I have total 7 disks need add to 2012R2 cluster.
5 are GPT disks and 2 are MBR disks.
But only 5 GPT disks can add to cluster after all disks validated and didn't see any error in the validate report.
That 2 MBR disks are using by Hyper-V VM. And the Hyper-V host just added as cluster node.
Is there anyone know why I can't add these 2 MBR disks to cluster?
