We had a particularly impressive server crash a couple of weeks back, where our RAID controller blew up ... the result was some pretty impressive data corruption ... since the crash, we've been having a problem with Zope 2.5.1, particularly the ability to manage the site. When trying to Add Folder, it results in an error of: Traceback (innermost last): File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 127, in publish File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 127, in publish File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 127, in publish File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 122, in publish File /usr/local/www/Zope/lib/python/Zope/__init__.py, line 126, in zpublisher_exception_hook File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 102, in publish File /usr/local/www/Zope/lib/python/Zope/__init__.py, line 173, in commit File /usr/local/www/Zope/lib/python/ZODB/Transaction.py, line 234, in commit File /usr/local/www/Zope/lib/python/ZODB/Connection.py, line 348, in commit (Info: (('OFS.Folder', 'Folder'), '\x00\x00\x00\x00\x00\x003\x97', '')) File /usr/local/www/Zope/lib/python/ZODB/FileStorage.py, line 668, in store (Object: /usr/local/www/Zope/var/Data.fs) ConflictError: database conflict error (oid 0000000000003397, serial was 034b1b936fdaccb3, now 0000000000000000) I tried to run the fsrecover.py script on the Data file (a copy of it), and it closes with: exceptions.ValueError: unpack list of wrong size So I'm figuring that the Data.fs must be one of the casualties of the crash ... Now, Zope is a new one for me, and really have no idea of what the Data.fs is even used for ... is it something that I can just delete and Zope will just start building it from scratch? Or is it something that I can regenerate based on information from the file system? I found the following link: http://www.zope.org/Members/itamar/CorruptedZODB And tried it, but it made no difference ... from what I read in the URL, it sounds like I'm basically removing transactions, one at a time, from Data.fs ... what does that affect (ie. what am I losing for each transaction I remove)? how far back can/should I remove? Pointers, as well as advice, is greatly appreciated ... Thanks ..
