Yep, I can imagine it isn't that easy indeed.

It does just works, and works well, until the mfsmaster goes down. Then its lottery.. if you're lucky, you'll get metadata successfully recovered. If not.. you're lost.

I've been with Thomas implementing his solution on a few boxes for test purposes and it really looks promising, however not completely reliable yet. Hopefully he'll have the time to work it further.
