Maybe I missed mentioning it, but if there was no fammed-old object then it would give a KeyError: 'fammed-old'. If I created a new plone instance in the spot where it was expecting, it would instead give me a POSKeyError.

That's what I've been using... the zopectl debug. It basically says that there is a KeyError: 'fammed-old' when I try to access a part of the object.

Looks like a buggy "fsrefs":
It complains that oid 0x0L refers to missing oid 0x1L and
then it complains that oid 0x1L refers to other missind oids.
Apparently, oid 0x1L is there. Otherwise, it would be difficult
for it to refer to missing objects.
Do not trust this "fsrefs" version.

Re: [ZODB-Dev] Re: KeyError / POSKeyError
Okay, I didn't think it'd work, but I tried using a backup. It didn't work. I only have backups of the ZODB with the plone instance I want to keep. Unfortunately, it and all the backups seem to be hung up on finding the broken plone instance in a completely different ZODB. I didn't bother making backups of the broken plone instance because... well, why recover something that's already broken. The relation is that the broken plone instance was as far as I could get with migrating a website from an old version of Plone and I was able to copy most of the contents over to a new instance of Plone. All I used was the "copy" and "paste" inside the ZMI. I don't understand why it's still looking for that broken version, but I have no idea how to alter the "good" site so it stops looking for that broken version that's no longer there (at least, not in the state that it wants it to be). -Tim On 3/23/07, Dieter Maurer <[EMAIL PROTECTED]> wrote: Tim Tisdall wrote at 2007-3-23 16:32 -0400: > I tried running a pack on the database via fsrecover.fs and here's >what I get: > >- >Recovering Data_fammedmain.fs into Data_fammedmain-recovery.fs >. 1 . 2 . 3 . 4 . 5 . 6 . 7 . 8 . 9 . 0 >0 bytes removed during recovery >Packing ... >Traceback (most recent call last): > ... >return referencesf(self._file.read(dh.plen)) > File "/opt/Plone-2.5.2/lib/python/ZODB/serialize.py", line 645, in referencesf >oid = oid_loaders[reference_type](*args) >KeyError: 'n' Looks like the physical structure of your storage is okay but some object data is corrupted.

You need to provide the full traceback so we can tell where it is coming
from.
My guess (though I'm surprised by the particular error) is that you have
perhaps got content owned by users in a user folder outside the site
that is no longer accessible when you mount the database on its own. If
that is the case then you need to write a script to fix up the
__ac_local_roles__ on the affected objects.

[ZODB-Dev] Re: KeyError / POSKeyError
You need to provide the full traceback so we can tell where it is coming from. My guess (though I'm surprised by the particular error) is that you have perhaps got content owned by users in a user folder outside the site that is no longer accessible when you mount the database on its own. If that is the case then you need to write a script to fix up the __ac_local_roles__ on the affected objects. Laurence Tim Tisdall wrote: Here's the thing... I get a KeyError if that ZODB is on it's own, but if I create a fammed-old object that's similar to what it's looking for, it will then throw a POSKeyError. The Plone instance was created fresh and then only the file contents of the old site were copied over to the new instance. The migration of the old Plone site didn't work, but it did manage to make it so I could access the files contained within and copy them over. I didn't copy over any stylings, products, users, widget things... I'm pretty sure I just copied over AT types and a few basic zope files (like DTML files and zope page templates). -Tim On 3/23/07, Christian Theune <[EMAIL PROTECTED]> wrote: Hi, Can you tell whether you get a KeyError or a POSKeyError? If you get a KeyError, it's likely that the app (Plone) is broken, e.g. during the migration you mentioned. A POSKeyError would (very likely) not talk about a a key like 'fammed-old', so I suspect you don't have a corruption in your storage/database but your application.
