On my previous media server I had two hardware Raid5's (4x4TB & 3x8TB) pooled with DrivePool, and it worked great for years.
Now I have a media server with 3x12TB in Storage Spaces Parity mode and a single 12TB disk. I want to pool these (and use rules for what is on which part of the pooled drives), but DrivePool does not see my Storage Spaces Parity volume (M-drive).
The M-drive is NTFS formatted just like everything else, but DrivePool does not see it.
What, where, how and why..?
