Is it possible to use several disks in the pool and some disks as local disks?

Question

I have 4-node S2D cluster with 12 disks each on Windows Server 2016 Insider Preview 16257. I applied this settings by Cosmos Darwin to prevent adding new disks to the pool automatically

Is there any way to prevent Storage Spaces Direct from automatically adding disks?

but when I connect new disk, with this cmdlet I can see (after few minutes), that the new disks are in the pool

(Get-PhysicalDisk | ? mediatype -eq hdd).cannotpoolreason 

Is there another settings to modify? Is it possible to use local disk in every node within Storage Spaces Direct? Thank you

Answer 1

Nope. As a workaround you may want to patch the registry and ask your disks to report S2D-incompatible drive type, they will be ignored by S2D by default in such a case.

Answer 2

I second the BaronSamedi1958's answer. There is nothing else could be done. And yet Storage Spaces Direct is too buggy to run production. I believe you use Preview version for nothing but evaluation.
