I am a little stuck here. Setting up a new server (for storage spaces) one of the disks we wanted to use for other purposes got pulled into the primordial storage pool. Somehow I see no option to remove it. There seems to be no way to change the CanPool attribute on the disk.
It does not show up under get-disk, and under get-physicaldisk it is marked with "CanPool true".
How do I remove it from the primordial pool so I can format as basic disc?
