Will my current ZFS under Linux be recognized by FreeNAS?

[zamana]

Hi!

Currently my NAS, build from scratch and based on an Ubuntu Server 16.04 LTS, has a ZFS pool with 4 x 4TB disks.

After installing FreeNAS, does this ZFS pool will be recognized or I will need to backup, create another ZFS under FreeNAS and rebuild the pool?

Thanks.
Regards.

You should be able to use it. They are both OpenZFS and will be compatible as long as features which are currently only impmented in ZoL and not FreeBSD aren't used. Which should be the case.

I'm not sure if it will be optimal though.
