the 1.4.2-fc3 salvager is more likely to be helpful.

Well, this is it, the day I'd always feared...
Server is running openafs-1.4.1. I did a "vos remove" on
root.cell.backup and suddenly couldn't access root.cell. Shut down
the fileserver, started it back up, and not it can't attach:
$ vos examine 536870912
**** Could not attach volume 536870912 ****
RWrite: 536870912 Backup: 536870914 number of sites -> 1
server research.CS.Berkeley.EDU partition /vicepa RW Site
Everything for this cell is in one 3.3gb volume (root.cell); I hadn't
yet gotten around to splitting it out into separate volumes.
Help! Is there any way to get 'bos salvage' to make the volume
attachable? Or in any other way recover the files or some subset
thereof?
The good news is that 'du -chs' of /vicepa gives exactly the right
size (to within a few meg), so maybe I have reason to hope that my
data is still there somewhere...
SalvageLog (below) looks like it's stopping at /atmelx and getting
upset. I'm quite happy to nuke that directory since it hasn't changed
since the last dump. But other very, very important stuff has changed.
Help!

I had a problem moving some volumes (posted earlier today). This is the
exact type of errors I'm getting in the salvage log for a users home
directory volume. I've spent the last 6 hours trying to recover it to no
avail. I would suggest a couple of things. First do a vos dump so you can
at least get back to the same state you're in. Second, don't continue to run
salvager - it only seemed to get my volume in a worse state to the point
where it's now saying:
vol-is-afs:/usr/afs/logs# tail -f SalvageLog

Doing some searching on the Root directory not found error yields
non-promising results. Any help recovering volumes from either state would
be appreciated by myself as well.
