Expanding Storage Pools in Hexos – Support for Drives of Different Sizes?

[bonecrusher]

Hi everyone,

I'm considering purchasing Hexos, but I want to clarify how storage pool expansion works, especially regarding drives of different sizes. Since Hexos is based on TrueNAS, and TrueNAS does not support adding drives of different sizes to an existing pool without significant limitations, I’m wondering if this restriction carries over to Hexos as well.

One of the features I appreciate in Unraid is the ability to add drives of varying capacities over time without losing storage efficiency. Does Hexos offer a similar approach, or does it follow the same vdev-based structure as TrueNAS, where expansion requires entire vdevs of matching drive sizes?

Any insights would be greatly appreciated!

Thanks!

Yes hexos will have similar limitations. 

You cannot expand with smaller drives but you can expand with same size or larger drives. 

If you expand with a larger drives it'll be treated as the same size as the smallest drive.
