venti/vac/vacfs trouble
J.R. Mauro
due to connection issues, but once I finally got back to doing a vac,
I couldn't see what I archived in vacfs. I'd been using vac with the
-a option so that I get the nice /YYYY/MMDD structure. Using vac about
a week after my last backup succeeds, but when I then use that score
to mount vacfs and try to ls in the latest directory, I get one of the
following errors:
/bin/ls: reading directory /n/dump/2009/0812/user/: Numerical result
out of range
OR
/bin/ls: reading directory /n/dump/2009/0812/user/: Input/output error
There seems to be nothing wrong with the disc or connection, as I can
ls any older directory on the venti server through vacfs. Any help
would be greatly appreciated. (I would have tried filing a bug, but
I'm not entirely sure this isn't my own fault by not running vacs for
a week or so).
Thanks,
Jorden

It says "invalid score" and quits

I have rebuilt the index and done a checkarenas. The end of a
checkindex run says this:
# diff actual correct
isect block 0x8165e000
> 90b6df7c906d016269346a87d10bc8de54c670ac 7214126182 16 300 1
checkindex: 0 spurious entries, 1 missing, 0 wrong
checkbloom: bloom header mismatch
venti/checkindex: errors found
I ran checkindex with -f, but it didn't say if it tried or did fix the
error. I thought rebuilding the index would have repaired something
like this. I decided to run vacfs with debugging on and try to ls the
bad directory (from the last vacfile). Vacfs had this to say:

Does this give you any clues?

please run vacfs -DV, which will dump venti protocol messages too.
