Lack of this feature has kept me on Synology and their SHR-system. I can just slap in any drives of any size and it'll just adapt. As long as the new drives go in an empty slot or are bigger than the previous one, I get more space. Zero CLI commands needed. Now get this feature in unraid or TrueNAS and I'm switching.
