Makes sense. My understanding is not good enough to confidently make my own decisions, and I'm learning as Im going. The BPG says:
- The recommended number of disks per group is between 3 and 9. If you have more disks, use multiple groups If there was a reason leading up to this statement, I didnt follow it. However, a few paragraphs later, their RaidZ2 example says [4x(9+2), 2 hot spares, 18.0 TB]. So I guess 8+2 should be quite acceptable, especially since performance is the lowest priority.
