You could try the following (back up everything first, of course!):

 - Stop the application server, then the storage server.

 - Test the existing storage file:

   $ /path/to/python /path/to/zope/utilities/ZODBTools/fstest.py \
     var/Data.fs

 - On the storage server, concatenate the 'tmp' file to the end of the
   main file, e.g.::

   $ cat var/Data.fs.tmp >> var/Data.fs

 - Move the 'tmp' file aside, e.g.::

   $ mv var/Data.fs.tmp var/Data.fs.tmp-ASIDE

 - Test the concatenated storage file:

   $ /path/to/python /path/to/zope/utilities/ZODBTools/fstest.py \
     var/Data.fs

 - Restart the storage server in debug mode and watch the log output:

   $ bin/zeoctl start && tail -100f var/error.log
