Looks pretty bad, but you can try readonly mode with transaction
rollback and recheck:
zpool import -f -R /GoelliZFS1 -N -o readonly=on -F -X GoelliZFS1
Now by options:
-f: force import;
-R: change root directory for all mounts;
-N: do not mount filesystems;
-o: pass extra options to zfs layer;
-F: try to discard last few transactions;
-X: check thoroughly each transaction skipped (undocumented).
You can skip -X for the first time, with -X it can take tens of hours.
If this doesn't help I welcome you to our club of 'I borged my ZFS'. I
lost my pool after fiddling with my hardware so last few transactions
got damaged and I constantly see only yell on 'bad objset' but I can't
mount any other objset.
