Oh thanks for the tip! I’ve edited my comment to reflect the minimum of 4 drives for a RAID6 array.
I’ve not used RAID6 for a small array like that before so I didn’t know it had a conventional lower limit. From the technical sense it doesn’t have to have 4 drives, it just wouldn’t make any sense to use it that way so I see why software wouldn’t support such a use case.

Please explain how you think you can distribute two sets of parity data across a three drive array?
Drive 1: A, Drive 2: 1/2 A, Drive 3: 2/2 A. Drive 2 + Drive 3 = Drive 1. Hmm that would only be one set of the party though. So you could also add 1/2 of A to Drive 1, and 2/2 to Drive 2 so that the parity on Drive 1 + Drive 2 = Drive 3. Which is extremely silly, and doesn’t make a lot of sense to use in the real world.
