Hi everybody, I looked around the Zope site and mailing lists, but I wasn't able to find an answer to my problem. I'm using the CVS version of Zope2. I did an update yesterday. Since then, there's been some commits. I just started my web site project using Zope running with ZServer, when I began to have problems doing Cut-Paste operations. I thought at first that I messed the permissions or something because of my lack of experience with Zope. Little did I know at that moment that my Data.fs was corrupted very badly. So I tried to restart Zope, but it refused giving me this backtrace: [zope@petechie ~/Zope2]$ ./start Traceback (innermost last): File "/home/zope/Zope2/z2.py", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "/home/zope/Zope2/lib/python/Zope/__init__.py", line 110, in ? DB=ZODB.FileStorage.FileStorage(Globals.BobobaseName) File "/home/zope/Zope2/lib/python/ZODB/FileStorage.py", line 303, in __init__ self._pos, self._oid, tid = read_index( File "/home/zope/Zope2/lib/python/ZODB/FileStorage.py", line 1515, in read_index if read(4) != packed_version: raise FileStorageFormatError, name ZODB.FileStorage.FileStorageFormatError: /home/zope/Zope2/var/Data.fs I then logged to Zope web site to get information on how to get my Data.fs fixed. I read the http://www.zope.org/Members/itamar/CorruptedZODB document and downloaded the tranalyzer.py python program. I then understood what the backtrace already told me. The first 4 bytes of any ZODB files should be something like "FS21". Instead, I have garbage in my Data.fs: [zope@petechie var]$ python tranalyzer.py Data.fs | more Traceback (innermost last): error: Not a .fs file (at least, not a kind I know about) magic = 6TÆ Just for the record, Data.fs.in is read easily by tranalyzer.py. How can this happen? Any idea? My only "guess" is that it has to do with the Data.fs file being used by ZServer over an NFS partition on Linux. This is only a guess, but I really can't see any other thing I could have done wrong. This doesn't really bug me for the moment as I only had a couple of hours put in my site, but I would like to prevent it from happening again.... yes I do backups, but only once a day ;-) Thanks for your help/comments.
