Hi Victor,
Here's the output of 'zdb -e -bcsvL tank' (similar to above but with -c).
Thanks,
Brad

This tells us that there are 5 corrupted objects in the pool, and all of
them were born during txg 2435914.
Since it is the last synced txg for this pool, it is likely that
previous synced txg may be intact.
We can try to verify this. To do it could you please run the following
while booted off SXCE b113:
zdb -e -u -t 2435913 tank
zdb -e -bcsv -t 2435913 tank

victor
