This seems to indicate a massive file system defect. Using
"fsck -fy /" enables fsck to use its full spectrum of repair
(in comparison to -p "preen mode"). Check if _the same_ problems
re-appear. In this case, they could not be fixed properly
and the file system won't get the "clean" indicator.

Re-initalize the file system and restore from a recent backup.
If you don't have one, you could try to backup from the damaged
file system with "dump", then run "newfs", and then "restore".

I've seen a comparable problem very few times, but usually
a second run of a forced full fsck solved the problem.

Are you sure the disk (!) doesn't have problems after the
power outage? It's possible that you're seeing a "hardware
issue" here.
