The RPM database should be verified more often than it is now. I've posted
on this topic to the fedora-devel list.
With FC6 there has been a spate of RPM database corruption. It happened to
me: though there may have been incipient corruption in my FC5, after
--rebuilddb and upgrading successfully I found more corruption later. This
brings up that the RPM database is just assumed to work, but isn't being
checked until it falls over.
I propose that the RPM database should be verified on a regular basis. I
have written a utility, rpm_verify_db, to automatically verify and repair
the RPM database, via a daily cron job. Reports of errors are syslog'd,
emailed to root, and shown by logwatch. It could be incorporated into the
RPM package, or even Yum. It can be found at
<http://georgeanelson.com/rpm-verifydb.htm>.
I propose that Anaconda should check the RPM database before starting an
upgrade to an existing installation. Checking takes under a minute on my
system, so it should not be objectionable. Anaconda should offer to repair
a damaged RPM database (if the Package file is OK) before proceeding with
the installation.
I suggest that the --verifydb command should not be undocumented in RPM and
its manpage. This seems to be on purpose, but I think it is a mistake.
I would like some feedback about these proposals. If they are acceptable I
will file RFE bugs on them.
My knowlege of things RPM is superficial. It would be a good idea to have
my proposed verification and repair methods criticised by authentic RPM
developers.
your idea is good.
but do you test the scripts? it seems that the return value of "rpm
--verifydb" has some problem.
whether your rpmdb is broken or not, the return value is same(all is 0),
so the scripts will not work well
i remove my rpmdb directory(rm -rf /var/lib/rpm), the return value is
still 0, same with right rpmdb
I will be away for a few days, starting tomorrow, Thursday, US Thanksgiving
holiday.
