[ZODB-Dev] CorruptedDataError sniff !

[Eric Brun, with a corruption problem]

This is a good place to discuss it, but I can't tell you more here than I
said on zope-dev earlier this morning:

Did you run fstest before or after running fsrecover?  It's better to run
fstest first.  fsrecover throws information away.  fstest will almost always
find nothing to complain about if you run fsrecover first, but then you've
also thrown away evidence about the original nature of the damage.

Same question:  did you run fsrefs before or after running fsrecover?  If
you ran fsrecover first, fsrefs may simply be complaining about the
information fsrecover threw away.

I know you're in a hurry <wink>, but it's unlikely you're going to recover
from this quickly.
