The current has few bits updated about diagnostics (that concerns the 0x31 error messages), the storage pool issue depends on how the pool is filled with data - once the BIOS limits are exceeded, we will be unable to read those data blocks and the errors will appear...

Yes, well the catch there is that with this machine, you can not use those 4TB disks fo boot pool, unless you will create separate smaller partition within BIOS limits. But if you do not plan to make it bootable, the data pool does not concern boot loader other than we do probe disk devices to detect [boot] pool configuration and to make it possible to boot from different pool.
