Hi, As some of you might have seen I have had severe problems with my Data.fs today. Manged to resolve the problems by using the fsrecover.py. All the sties are up and running, but I cannot add any data. I get the following traceback trying to add a regular Folder at the root level. Is there a way to solve this problem ? This is a serious problem for me! I have tried a new recover but no errors are found and no bytes are removed during recovery. Traceback (innermost last): File /usr/local/Zope-2.5.1b1-src/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /usr/local/Zope-2.5.1b1-src/lib/python/ZPublisher/Publish.py, line 127, in publish File /usr/local/Zope-2.5.1b1-src/lib/python/ZPublisher/Publish.py, line 127, in publish File /usr/local/Zope-2.5.1b1-src/lib/python/ZPublisher/Publish.py, line 127, in publish File /usr/local/Zope-2.5.1b1-src/lib/python/ZPublisher/Publish.py, line 122, in publish File /usr/local/Zope-2.5.1b1-src/lib/python/Zope/__init__.py, line 126, in zpublisher_exception_hook File /usr/local/Zope-2.5.1b1-src/lib/python/ZPublisher/Publish.py, line 102, in publish File /usr/local/Zope-2.5.1b1-src/lib/python/Zope/__init__.py, line 173, in commit File /usr/local/Zope-2.5.1b1-src/lib/python/ZODB/Transaction.py, line 234, in commit File /usr/local/Zope-2.5.1b1-src/lib/python/ZODB/Connection.py, line 348, in commit (Info: (('OFS.Folder', 'Folder'), '\x00\x00\x00\x00\x00\x00\x00T', '')) File /usr/local/Zope-2.5.1b1-src/lib/python/ZODB/FileStorage.py, line 664, in store (Object: /usr/local/zope-prod/var/Data.fs) ConflictError: database conflict error (oid 0000000000000054, serial was 0339fe733cf5ddf7, now 0000000000000000) Best regards Petter Enholm
