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? --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --M9NhX3UHpAaciwkO Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJdZ2m8AAoJEA2k8lmbXsY0s1cH/1bndThgYuQNTdeNknIoEnjb 2GRJwggs/0f8QwvWiziVGvN1PhhDJYnDivgaljFVKJwecc9tobh/D+G57fjm2JKN pNTSIWDQ5VmPCPpb8a6ezGBrYHaY9zJVrZ2YjAV2E68Ghh3VHnpwXxs3Il2OasPw HFVm/37miIl6gH+1OngLs1S+A5/q8sq3596qRfbrNaBT2z4rve5gI5Y85xq8Gn7V 4/N6JY9kO9K88cAwKv7qPv4etqoJlsR/tQ41+GqhEENz2iziyi/Ogw0PWWnHS6q3 1O5dVSENddFvj5XHHBy3WJbgeHuDlkmt9c4kkrM3s57CbcK09mAZolAd+gM29Wg= =9jf/ -----END PGP SIGNATURE----- --M9NhX3UHpAaciwkO--
