Hi all,
My OS is fedora 3. After I restart OS the OS can't start successfully. Following is the OS's error report. Thanks for any idea.

I have never seen this before. I know very little about RAID setups, and if this is what you have then I can not help.

If however, you have a normal setup, the root = /dev/path _to _root should point to your partition that your root file system is on. (Eg root = /dev/hda5) You can change this at startup if you use grub by hitting the 'e' button when grubs menu appears.

Hope this helps

Thanks for the reply. I remeber the root directory'location is not /dev/hda5. how do I check the root's correct location when the OS start failed. Thanks

The best method I could suggest would be a livecd. A few reasons for this:-

1) you then have a recovery tool for the future - just in case
2) you get to see a different distro - and how you can set up your desktop
3) helps show you the settings needed for your computer eg network settings, modules needed etc
4) lets you edit files on your distro.

When you load a livecd it will basically show you what you have, and you can then figure out where your root file is. Worth the download. I would recommend "slax" but I am biased. There are heaps out there and if you are on broadband, you looking at a much smaller download (around 250mb).

Thanks. I set BIOS Boot from CDROM. Then I use the FC rescure CD. Then the OS in the Rescue Mode. The following is the Rescure Mode message. "You don't have any linux partitions. Press return to get a shell. the system will reboot automatically when you exit from the shell." Then prompt: sh-3.00# . How do I do in the sh-3.00?

This is a little worrying!!

FC3 is a little unfamiliar, as I do not know the tools loaded. So try a few of these.

This should show the partitions you do have
This is the linux CLI partitioner - do not go changing anything unless you know what you are doing. This will show everything but not what is where. Write the partitions down to give yourself some info of what partitions you do have and then quit.
you should end up with a list similar to this

hda1 ntfs
hda2 ext3
hda3 swap
etc

Recovering this way is the hardest method.......... just to let you know :-)
