I've just performed the configuration to boot my Unraid server from USB to internal nvme and the system has booted from the internal drive as expected - except my ZFS pool and associated cache pool has now gone. The pools are listed but no drives are assigned. Is this expected? If I reassign the drives will the pools continue as before or have I lost my data? UPDATE - drives reassigned to the pools and all is now OK. Is this expected behaviour after using the internal boot configuration process?
