I am not a ZFS expert but can this be stored in a

You can try to delete zpool.cache (just rename so you can move it
back), import and export should re-create it.
I dont have one in /etc just in /boot/zfs. Doing a strings on that
file, I dont see reference to zbackup1 however, just the real pool,
zroot. So strange. I am guessing its stored somewhere specifically on
the individual drives?
OK a little further. Looking at the output of zdb -l /dev/ada0 I see
LABEL 1 has the old info where as zdb -l /dev/ada1 only shows the active
pool zroot. So I guess the question is how do I get rid of LABEL 1 on
ada0. I guess I could offline the disk, do a full zpool-labelclear on
/dev/ada0 and then "replace" ada0p3 with ada0p3. But I wonder if there
is a more surgical way to do it ?
zdb -l /dev/ada0
