What do I need to creata an F-9 rescue disk. I would prefer not to download an entire dvd due to my bandwidth allocation. Can I make one from files on the Live CD?
Thanks.

If I recall correctly, the Live CD is already usable as a rescue disc, just choose the appropriate option when you boot. Check the notes to be sure.

No, if that should work then nothing will I guess?
It begins to boot but shows a mess of permission errors and then " init: tty5 respawning too fast, stopped" and that's all she wrote!
I've probably lost it ...
Maybe I should try the F-10 Lice CD since it was in the process of changing things over?
The live CD will boot the computer if I let it go but then I don't know how to get on the original files on my hard drives? I've never been confronted with this problem until now.

Dumb question - how are you booting into the rescue mode? (The steps you are taking - not just boot from live CD.)

The Live CD presents a normal grub screen when you hit enter and offers several options, boot from local drive, seems appropriate. That produces the same result as if I just let the boot proceed normally without the CD. I get a raft of errors and it finally gives up and says stopped.

Ah - that is the problem - you are not booting into the rescue mode. You are booting the same way as if you had booted from the hard drive. Try entering "linux rescue" at the Grub prompt. (I normally the DVD image or the boot image off the DVD, so there may be an extra step when using the Live CD to get the Grub prompt, or a rescue option on the Grub menu.)

Ok, I can do that and fdisk sees the two drives, /dev/sda and sdb but not /dev/sdc which I believe is the CDROM drive? And that's what's stopping the F-10 install from progressing, it can't fins /dev/sdc2? But if it is the cdrom it used it to get started!
And I still can't ssh into box6 [the failed unit]. It just reports no route to host.
What do I need to do next?

This leads me to suspect that you don't understand what rescue mode does.
You should boot the computer that failed from the rescue cd. After it's booted, you can use the keyboard that's attached to that computer to "do things", be that copy data off of of the hard drive or run fsck or whatever you need to do.
sshd is not started by default when booting in rescue mode, so you won't be able to log into that machine remotely unless you take additional steps (that also involve typing on the keyboard that's attached to the computer you just booted in rescue mode) after booting it up.

Yes, I've been typing a lot of things on the keyboard but obviously not the right things.
The computer shows that /dev/sda and sdb are there but I can't mount them because it doesn't see my original /etc/fstab apparently? Well even then I don't know how to address those drives because of the LVM? I would be quite happy if I could access those drives and extract data. There's nothing life or death on there but I would like to get a few things off if I can't fix it so the install will finish. I don't know why preupgrade is looking for /dev/sdc2. In fact I'm not sure what sdc2 is, it's either the CDROM drive or another drive I pulled to use in this computer, the original XP drive.
Whatever I can't mount either drive since I apparently don't know the right procedure if it can be done?
Service sshd status on both computers is running but I get "no route to host" in both directions, going from either one to the other but then I don't know if the "bad" computer is still 192.168.1.6 with the Live CD running linux rescue?

Bob, you might try this:
1. Boot from a Live Spin
2. Use the Logical Volume instructions here:
http://forums.fedoraforum.org/showthread.php?t=214137
to mount the root and boot partitions then to re-install grub
3. Reboot server and all is well
I posted this recently when I had an upgrade issue on an F8 machine. My problem was that rescue disk boot does not give you the tools to mount an LVM if "chroot" doesn't work. Booting a Live Spin gives you everything you need to mount up, fix the problem, then you can reboot.
Just follow the link and you will (should) find everything you need.

Yes, that seems to get me what I need! Now if I can just figure out how to use it! I'll muddle through somehow. At least now I can see my files! Long shadows here, time to feed horses.
Thanks much.
