I had some odd boot-ups in my Fedora Core 5 LAN installation where I couldn't log in to my low level users and when I tried to log in to root, I was bounced right out with a warning saying something about only logging in for 10 seconds. And also, I found that one of my Logical volumes was not being recognized and I would have to go back in and "reinstall" it -- or whatever the process is called. Eventually, when I tried to reboot, I was getting file system warnings and dropping to a file check command line. Finally I tried running fsck without the -p or -a as suggested, but who knows anything about how to respond to those prompts. So I muddled through guessing a few times and finally tried "fsck -p" which didn't work and "fsck -y" which also didn't work.

Now, when I boot up I pretty consistantly get ...

... and the whole thing grinds to a halt. I didn't get an exact quote of the errors, but I hope somebody gets the general idea.

Does anyone know what happened and what I can do to fix things?

Sounds to me like your hard drive is nearing the end of it's lifespan. Try running smartd (if your drive is S.M.A.R.T. capable) that should tell you if there is a issue with your drive, getting errors about inodes being deleted and stuff sounds like something is a bit quirky.
