Server 2022 Storage Bus Cache with Storage Spaces can't identify cache devices
I have a brand new, fresh out of box server with a clean install of Server 2002 Standard. The server has 25 SATA spinning disks presented to the OS in JBOD fashion, and 4 6TB NVME drvies, again presented in JBOD. Following the guide (Storage bus cache on Storage Spaces | Microsoft Learn) I've also ensured that cluster services is enabled. Running Get-PhysicalDisk shows the drives as they should, and correctly displays the media type of SSD and HDD, as well as showing that they can pool.

The only post I could find was one where another person seemed to run into this and ran DISKPART, and CLEAN on each disk. I've done this, but no success or change whatsoever. I've also confirmed that despite the error message, it isn't a false positive and no pool is created. The only pool that exists is the primordial one. There doesn't seem to be any way to force selection either, and it's unclear why Windows is ignoring what's reported in DiskPart. Does anyone have any advice here?
