I was able to pull all but 73 out of more than 1000 packages listed in /var/log/rpmpkgs from /var/cache/yum plus the CentOS 3.9 CD set. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I think this should be a berkeley DB recovery routine that is specific to the version being used by rpm. I have recovered the OpenPKG rpm database using this technique using the standard bdb db_recover program.

[CentOS] Recover rpm DB corrupted by disk failure?
Over the weekend my workstation (still on CentOS 3) started showing SMART errors, so we shut it down and moved everything onto a new drive. On reboot, the RPM database reports as corrupted and "rpm --rebuilddb" segmentation faults. Is there any reasonable way to recover from this, short of a complete reinstall? The machine is otherwise up though it's quite likely some files have been lost. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
