Hi guys. It seems that one of our customers has a corrupted BTree. I would love for someone to provide some insight on how we can recover the data.
we have two databases: 1 for resources and 1 for 'content'. resources contain lots of very big files. The system is configured to have a mount point at /plone/resources is a subclass of BTreeFolder, using internal data struct of OOBTree. anytime I iterate over the keys I get POSKeyError. anytime I iterate over the values the same. if I run BTree.check() on the data structure's tree attribute (the OOBTree itself) I get a POSKeyError. Running the utils.checkbtrees doesnt say this btree has a problem. While debugging this I had a conversation with sidnei about mounted databases. He recalled that if your using a mounted database you should not pack. If for some reason your mounted database had a cross reference to another database and somehow you had a dangling reference to the other database it would cause POSKeyError. Is there any other ways of "testing consistency" of FileStorage other than: - checkbtrees.py - fstest.py And any ideas how I can salvage the data? This BTree, of course, had the most valuable data. cheers -- Alan Runyan Enfold Systems, Inc. http://www.enfoldsystems.com/ phone: +1.713.942.2377x111 fax: +1.832.201.8856 _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
