AW: How to check integrity of database?

From: Markus Karg <markus.karg_at_quipsy.de>

I just wanted to know whether this *is* a sufficient check, or not. I'm asking this because I have often seen database that worked well, but used broken or misleading links internally. This means, never an error appeared, but the data shown to the user was screwed. So the question is: Does svnadmin verify actually test the FSFS integrity, or does it only read each file? If it does the first, I am happy. If it does the last, it will not find misleading links. That's why I asked for a special FSFS tool but not for a SVN tool. So is there a FSFS guru near to answer this?

Is this not sufficient?

svnadmin help verify
verify: usage: svnadmin verify REPOS_PATH

Verifies the data stored in the repository.
