Thanks. I'm humbly getting things done without a lot of python
knowledge and no zope experience. I wouldn't recommend this approach to
anyone, it's just some cowboy hacking.

Yep, the content type is created - it's just the file field that has the
odd storage. All other fields are normal.

Relstorage for load balancing and replication. that's about it. I
inherited the setup (yeah, I know, bad excuse). But Rethinking a
Data.fs solution to the problem is probably not going to help anyway.

I'm going to look into this stuff.
I stumbled on some docs that hinted you could call 'pack()' directly on
a single piece of storage, but I've yet to find them again. This might
be a solution.
