I don't want to include the OS itself as part of the storage space. I just want to 1TB of the drive for the OS and 3TB for storage spaces. I was going to install the system on an SSD but my SSD died...

I'm trying to create a storage pool for parity with 4 3TB drives and use 3TB of a 4TB drive that also has my OS.


When I go to create the pool the 4 3TB drives show up but the unallocated space...
