Even better, it will also correct any errors that are possible to
correct.  If you have enough redundancy in your pool and the damage
isn't too extensive, it will generally just fix everything for you.

In any case, the design of the filesystem is such that you're less
likely to end up with inconsistent state due to unclean shutdown in the
first place.

man zpool

for more information.
