Description Jan Kovats 2006-07-16 20:57:03 UTC

Description of problem:
The rpm Database doesn't seem to work anymore on my computer. It worked fine
and then suddenly without me fiddeling me with it yum didn't work anymore..
i coulnd't update anything. and when i try to install an rpm manually it says 
/bin/bash is missing, wich is rediculous.. i noticed that any package i ask rpm
about doesn't exist. Even  rpm -qv kernel says "Package not found" and i tried
rpm --initdb
and
rpm --rebuilddb
didn't do any good..
 /usr/lib/rpm/rpmdb_verify found /var/lib/rpm/Packages consistent

I expected some update did it.. 

Version-Release number of selected component (if applicable):

RPM, Version 4.4.2

How reproducible:

No clue
  
Actual results:

__db.001  __db.002  __db.003  Name  Packages

Expected results:

Comment 1 Jeroen van Meeuwen 2006-07-16 21:12:25 UTC

I've tried to assist this user with solving the issue, and I may have some
additional information.

After we found the rpm utility unable to find any packages (rpm -qv kernel, or
rpm -qv bash), we tested the /var/lib/rpm/Packages file for consistency with
/usr/lib/rpm/rpmdb_verify.

As it appeared to be consistent, we removed every single file from /var/lib/rpm
except Packages, and let the RPM database be initialized (rpm --initdb), and
rebuild (rpm -vv --rebuilddb). As these commands do complete without any
complaint, but do not recreate the files in /var/lib/rpm nor
/var/lib/rpmrebuild.*, we except something goes wrong.

When setting the German language (de_DE.UTF-8), the rpm -vv --rebuilddb shows
the following:

D: Baue Datenbank /var/lib/rpm in /var/lib/rpmrebuilddb.5656 neu
D: Erstelle Verzeichnis /var/lib/rpmrebuilddb.5656
D: Ãâffne alte Datenbank mit dbapi 3

D: Closed   DB-Index       /var/lib/rpm/Packages

The last message means "Memory access error" in english.

Please run memtest86+ on your machine and see how that works.  Also try copying
the /var/lib/rpm/Packages  to another machine (eg to /tmp/otherdb) and do rpm
--dbpath /tmp/otherdb/ -q bash.

Ok, the memtest86+ found no errors whatsoever. And when i try Packages like you
sugested on another computer it gives me the same.. Bash not installed. Although
when i just run rpm -q bash on this computer he finds it.. both fedora core 5.

Comment 4 Jan Kovats 2006-07-21 23:28:52 UTC

Ok since this seemed to go no where, and i couldn't install anything or update
.. well anything conserning rpm i tried updating with a re-spin from the fedora
unity project. this rewrote my rpm database so it seems.. lost all package
information but it works again. And it slowely rewrites itself if i just install
the same stuff as before.. so over time i will have my full package db again.
thanks to kanarip for his help and paul for trieng.

This problem appears resolved.
