I see it says that you can setup for a minimum of 2 drives (though not expandable) so long as they are a "similar size". I had a 12TB and a 16TB drive and it wouldn't allow me to create a pool. I decided to grab another 12TB drive thinking this might help solve the issue and so I could start out with an expandable pool right off the bat. When I installed the third drive however, it only set the pool with the 2-12TB drives. Does having one drive +33% exceed the rule of "similar size"? Is there an approximate percentage the drive needs to be within as opposed to examples in GBs?
I bought the 16TB while it was on sale thinking the 12TB was close enough and it was on sale at the time making it appealing for 1 of the drives with an eye towards eventual upgrades on the smaller drive(s). I would be fine with the 16TB drive being used temporarily at 12TB which is what I though I understood would be the case.
