I think it may have happened to me. Recently I had a "missing score" error
when I was looking for something in my dump fs. To assess the damage I did
a 'venti/copy -r' to a spare server, which told me 13 pointers had to be
rewritten.
I do sometimes get errors like this from my fossil server:
could not write super block; waiting 10 seconds
blistAlloc: called on clean block
but I've been assuming they are benign. Am I wrong?
My understanding of fossil is that venti writes are ordered such that
the store should not be left in an inconsistent state even after a
sudden shutdown. If that's the case, I'm guessing the most likely
cause of corruption was a careless experiment with venti when there
was already one running.
