I’m switching to Ubuntu server from FreeNAS and I don’t have a hard drive to back the data up to. Is is possible to import it into Ubuntu even though the data pool is split between two different HDD?
Answer
As Bruno Pereira has said, the zfs version number from FreeNAS needs to be equal or smaller than the zfs version number ubuntu supports. After zfs v28, this switched over to the need for support of the enabled zfs options.
For 16.04, the versions of zfs and FreeNAS 9.10 or even FreeNAS 10 are equal and a FreeNAS pool can be converted. I just converted a FreeNAS 10 trial installation myself for use under 16.04.
