[Zope] Data.fs data record exceeds transaction record

[Jaroslav Lukesh]

HI, I use this script, it will truncate DataFS.

#!/bin/sh
cd /path-to-your-instance/var
../bin/zopectl stop
rm -f Data.fs_ERR
#clear
cp -p Data.fs Data.fs_ERR
rm -f Data.fs.index
#diagnostic run
#../bin/runzope
echo ""
echo "................................................................"
echo "search for number after:"
echo "          ..../var/Data.fs has invalid transaction header at NNNN"
echo -n "put the number here:"
read  CISLO
python<<_EOF
f = open("Data.fs", "ab")
f.truncate($CISLO)
f.close()

_EOF
#start serveru
../bin/zopectl start
dd if=Data.fs_ERR of=Data.fs.MISSING bs=1 skip=$CISLO

Hello

2 hours ago I wanted to go to sleep... and "unfortunately" I noticed  
that our websites were offline since about 5 hours; I coudn't start  
zope anymore because the Data.fs seems to be corrupted. The quick  
solution has been to copy a 2 days old version of the Data.fs back...  
but I still hope to recover the old Data.fs.

But wenn I try to recover it with the fsrecover.py tool I get this  
error message:
