Thnank you for your tips,
So far i was able to either restore from the backup or salvage most of
the data. However I would like to recover some of the most recent bits
that are
currently lying in lost+found. Is there a way?
We do have ro copies of all volumes. Unfortunately vos release stopped
working about a month ago. Possibly due to the same reasons that
resulted to yesterday's disaster.
Hello!
I had to do this kind of work about two years ago. Take a look at this:
http://archiv.tu-chemnitz.de/pub/2003/0130/data/vol/start.htm
I found it very helpful. It's in German, but perhaps someone can
translate it for you. With the information provided in the document, the
tools mentioned in the text, and some cautious looks at the openafs
header files, I was able to reconstruct some of the fragments in lost+found.
For almost complete volumes structures (small and large vnode index
files and large vnodes must be available) I can provide you with a
script that restores the volume directory structure and files to another
location in 'real' filespace. Filenames are translated to the 'real'
filenames. For corrupted or missing files, you will get some
informations and the names, so you can try to find them in the remaining
fragments. The script also has a 'dry run' mode.
With the additional informations from your old ro volumes, you might be
able to reconstruct complete volumes. But it's tricky and you will need
some time.
The script and some of my other tools are a 'first try' and the comments
are german. I never had the time to rewrite the source. And I'm not a
very experienced programmer....
