Okay. Well, I tried dropping to single-user, rebooting off of a CD, =
and all attempts to =E2=80=9Czpool import -T NNNN=E2=80=9D give me that =
same error. Without any other ideas, I=E2=80=99m going to punt back to =
=E2=80=9Cnuke it from orbit=E2=80=9D and restore the full backup again. =
Takes 40+ hours, so was hoping to avoid it with some trickery, but, a =
recoverable situation.
Thanks.
