I get this error during the Storage > List Potential Cluster Disks test:
Failed to find or allocate arbitration sectors for physical disk {263c99e5-545c-42a6-b540-a3835cda60c8} from node XX.XX.com...Please ensure that all GPT disks have a Microsoft Reserved Partition (MSR) present. Error: 0x80070022.
I know how to fix this due to this forum post: http://tinyurl.com/mvkkuxv
While in diskpart, the disk that is returning the above error, has 0 free space, so I am unable to create the MSR partition. (The partition is empty so I don't know why diskpart thinks it has 0 free space.) How do I resolve this so that my cluster can pass all of the validation tests?
