[tlug] Hey, I'm all about the RAID now (Was: Setting up a RAID 1 with Ubuntu)


Well, that was pretty painless after all. My computer is now all RAIDed
up. Sweet.

Except, I'm not quite sure about this last stage of instructions on the
web page I was using as my guide:

Under the heading "Adding second HD to grub", it says to edit
/boot/grub/menu.lst, and add "something like this":

### To boot if sda fails ###
title Ubuntu 8.04.1, kernel 2.6.24-19-generic /dev/sda fail
root (hd1,0)
kernel /boot/vmlinuz-2.6.24-19-generic root=/dev/md0 ro quiet splash
initrd /boot/initrd.img-2.6.24-19-generic
### End mod ###

It goes on to say, and I quote exactly:

"Replace kernel and initrd filename if necessary. Reboot and try if
Ubuntu boot on the second hard drive."

The instructions are kind of vague and I'm not even sure what the goal is.

How do I know what an initrd filename to use?

I assume the kernel is the one I have installed. Is this something I'm
going to have to edit manually with every upgrade?

How do I "try if Ubuntu boot on the second hard drive"?

What is this actually doing?
