About your question about maximum RAID size: I cannot answer that. There possibly are different limits on what dmraid can construct via device- mapper (those are likely higher than 4TB). But then there might be limits that the meta-data which the BIOS uses impose. And I have no clue there. --

Yes, it sounds like that is the initial trigger. So somewhere between 3.16 and 4.4 the kernel got better in declaring which disk drives could be hot-plugged. And the AHCI and (likely) the fakeraid modes potentially support to hot-plug disks (you could have externally accessible drive bays).
