[Zope] corrupted Data.fs

[oliver]

Hi,

I am running Zope 2.3.0 on Linux and after a power failure the db is
corrupted:

 File "/home/ofrommel/Zope-2.3.0-src/lib/python/ZODB/FileStorage.py", line
218, in panic
    raise CorruptedTransactionError, message
ZODB.FileStorage.CorruptedTransactionError:
/home/ofrommel/Zope/var/Data.fs data record exceeds transaction record at
35816171L

now when I try to fix it with fsrecover I get the following error message:

[root@m945 var]# python ../lib/python/ZODB/fsrecover.py  Data.fs
Traceback (innermost last):
  File "../lib/python/ZODB/fsrecover.py", line 94, in ?
    FileStorage.recover(sys.argv[1])
  File "/home/ofrommel/Zope-2.3.0-src/lib/python/ZODB/FileStorage.py",
line 1529, in recover
    npos = shift_transactions_forward(
  File "/home/ofrommel/Zope-2.3.0-src/lib/python/ZODB/FileStorage.py",
line 1455, in shift_transactions_forward
    if plen: p=read(plen)
OverflowError: long int too long to convert


how can I fix the database now?

thanks for your help
