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 ----- Original Message ----- From: "Michele Marcionelli" <michele.marcionelli@math.ethz.ch> 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: 2010-05-02 00:38:39 WARNING OFS.Application Duplicate Product name After loading Product 'Five' from '/scratch/ZOPE-BOT/current/Products', I skipped the one in '/scratch/local/app/zope/2.8.9.1-2.3.6/lib/python/ Products'. 2010-05-02 00:38:39 WARNING Init Class Products.LDAPUserFolder.LDAPUserFolder.LDAPUserFolder has a security declaration for nonexistent method 'getAttributeOfAllObjects' 2010-05-02 00:38:39 WARNING Init Class Products.LDAPUserFolder.LDAPUserFolder.LDAPUserFolder has a security declaration for nonexistent method 'getAttributeOfAllObjects' 2010-05-02 00:38:39 WARNING Silva Silva Documents require upgrading.
