Useful ZODB tools
Here's a great link about maintaining your Data.fs zodb.
In particular, given a standard Plone unified installer setup, you can run these from within your instance.
Low level check:
./bin/zopepy ../Zope-2.10.9-final-py2.4/utilities/ZODBTools/fstest.py var/filestorage/Data.fs
The above produces no output under normal circumstances. It's supposed to support a -v option, but that doesn't seem to work properly.
Object sanity check:
./bin/zopepy ../Zope-2.10.9-final-py2.4/utilities/ZODBTools/fsrefs.py var/filestorage/Data.fs
Again, no output if all is well and -v doesn't work as advertised.
Human readable dump:
./bin/zopepy ../Zope-2.10.9-final-py2.4/utilities/ZODBTools/fsdump.py var/filestorage/Data.fs > fsdump.output
Lots of output here. One line for each object in each transaction.
