I got myself a Quad SATA HAT for my Raspberry Pi4 which runs on openmediavault and supports RAID 0, 1 and 5.
Yes, I know about RAID 5 and parity but I want to use RAID 1.
It would be a waste of the Quad SATA HAT (since there is a DUAL version, too, but I got the Quad version) if I used only 2 HDDs.
That's why I ask:
Is it possible to define two RAID 1 (2 x 2 mirrored HDDs) with openmediavault?
