R: [Zope] Corrupted data.fs

[trashMan]

Ciao marco,

 there is a command-line utility in lib/python/ZODB/fsrecover.py that will
repair damaged Data.fs files. 

First back up your Data.fs then 

>python lib/python/ZODB/fsrecover.py var/Data.fs


If the problem persist, you can try
http://www.zope.org/Members/tsarna/Tranalyzer 

Regards.

Oggetto: [Zope] Corrupted data.fs

Hi all.

We're experiencing nightly corruption of a Data.fs in an intranet
application.

We've removed all the packing/backup stuff, we've moved from zope 2.6.4 to
zope 2.7.4, but we still have data corruption in the morning.

Here is the error from the event log:

CorruptedDataError: 
^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@
^@^@^@^@

I'm quite confident the problem is outside of Zope, but I would like to have
some pointer on where to investigate in order to undestand the problem.

Regards
Marco
