Fortunately, I have an 11.2 guest in bhyve. I exported the pool from the
host system, made the physical device with the problematic pool
available to the guest, and voila: https://termbin.com/6kh8
My pool is up and running. Thank you!
I'm only wondering now, if I did an export/import on a 11.3 system,
would it have made any difference?
