Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

i have install rh7.1 on a amd 900 mhz with wd 40 gb drive, geforce2 mx ,256 mb mem,abit kt7a rid mobo. all of the install went fine and got everything configured. my kernal was 2.4.2-2. i ran it for a week to make sure no errors and everything work ok. then i registered with rh and got errata . then i went thru update and selected all the rpms that it showed to apply to my system. i went thru the upgrade and did not get any errors. so once it was done i figured i would reboot to see what kernal msg would show and if did upgrade kernal(2.4.9). when i rebooted i got this msg and it froze.
ext2-fs : unable to read superblock
isofs_read_super : bread failred dev=09:02 iso_blknum=16 block=32
kernal panic : vfs unable to mount root fs on 09:02
i figured it had something to do with the new kernal with ext3 and ext2 fs. i been reading about both systems. but cannot determine what i need to do.
patch the kernal or migrate ext 2 to 3 or what ??? any help would be greatly apprecaited.
not sure , when the update kick off and show all the rpms that were applicable to my system. i told it to select all of them . not sure if that was one or not. when the update ran it create what looks like a backup of the old version and put it in lilo as linux bak.
i can still bring this up with no errors.
having the exact same probs but slightly different system
Sorrie, imma a newbie to linux and i tried looking through the How-To doc for the kernel, but im not seeing anything which directs me toward fixing the problem with the ext2-fs specifically. Is there anything you can suggest to narrow down my search or a more specific fix to the problem?
to further elaborate, im asking more along the lines of where can i find the ext3 module or whatnot because i tried doing a few search for google on ext3 module and don't get anything worthwhile.
I've found a temporary solution to this. If I understand correctly, it looks like the boot loader thought the root partion was on a raid device (09:02). Weird. I'm able to boot the new kernel by pressing F2 when booting and manually entering the root parameter:
Now I just need to figure out where to put this so that I don't have to manually enter it each time. I thought it might be grub.conf, but that doesn't seem to do it and I can't find etc/lilo.conf. Does anyone know how do to this? Am I headed in the right direction?
Also, how can I determine which bootloader the OS is actually using?
here is what my grub.conf looks like [when grub comes up i have a list of each kernel I can boot to after I upgrade]:
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda7
# initrd /initrd-version.img

I am presuming you would need to uncomment out the:
I saw that in another post and tried it, but there was no change. I modified /boot/grub/grub.conf. This is the correct file and location, no? Also, as I mentioned before, I still don't know how to determine if i'm using GRUB or LILO for sure. Is there a sure fire way to positively identify your boot loader? The stuff flashes so fast at boottime that I can't see it there. I know it's basic but like I said I'm very new.
