I mentioned last week that I was thinking of upgrading to Fedora Core 4. The good news is that the upgrade went well. The bad news is how I ended up doing it.
I knew I was in for trouble when I booted my machine and fsck said "The system appears not to have shut down cleanly" or words to that effect -- in fact, it had shut down clean as a whistle. To make a long story short, it cleared so many inodes in /usr and / that I could only boot to single-user and only a few programs would run.
I booted from an Ubuntu live CD and downloaded ISO's for FC4. Then I had to boot FC3 again to use cdrecord to burn the CDs -- fortunately that still worked. I did an upgrade, and after a few runs of fsck and badblock, I had a working system again. Surprisingly, yum found about 250 packages to update.
I'm still not sure how the disk got fratzed. We've had a couple of power outages in our area lately, so I'm assuming there was a power spike or some such.
