pivotroot: pivot_root(/sysroot,/sysroot/initrd_failded:2
umount /initrd/proc failed:2
Freeing unused kernel memory: 156k freed
Kernel panic: No init foung. Try passing init: option to kernel

stop at here...what's the matter????

how to fix this problem , please help

I think your Hard Disk is out. Do you have a backup?

I think that either the hard disk is on the way out or your file system journal is trashed.

First try to boot in single user mode
Then check HDD for errors

Well, it says corrupted filesystem. The best way to proceed is to load a live CD distro on to the system, and run fsck on the affected partition. That might fix you right up.

If it doesn't fix you up, then what you do next just depends on the error messages that come back from fsck and from the system message log (which will probably also print on the system console - ctrl alt F1).

The server is red hat and i haven't any red hat cd...
can i use another linux live cd to boot it?
How to boot into single user mode??
p.s. sorry to all friend , i'm not a linux user so i really don't know

after restart press "e"
I only see

grub edit> root (hd0,0)

one line?

root (hd0,0)
kernel /vmlinuz-2.4.20-8smp to root=LABEL/
initrd /initrd-2.4.20-8smp.img

Select the 2nd line and hit the e key and then add the word single to the end of this line

kernel /vmlinuz-2.4.20-8smp to root=LABEL/ single

reboot

same problem

did after the "root=LABEL/" it will show my HD?

Boot into ANY Linux live CD, such as Knoppix or Mandriva One, and do your work from there.

Where you put the word "single" is correct... If that didn't drop you down to single user mode, try this:
If it works, you should then be able to run e2fsck on your root partition. Good luck!

I'm following this thread because I have identical problem (but I'm on FC2). This server was sitting on a shelf for 6 months - no power - completely unused. It was a backup server. It has raid5. The root partition is hda2. Yesterday I decided to make it useful again.

It booted but I noticed some EXT3-fs errors. The filesystem came up in read only mode also- another indicator that there was a problem. Today, when I tried to log in to start working on it, it wouldn't accept my password.
I rebooted. Reboot ended badly:
"kernel panic no init" message appears. Followed instructions found in this current thread to boot into single user because I'm hoping to run e2fsck.

I think I am in single user mode because at the end of the boot I get this:

(none) login:

But I'm back where I started this morning where it doesn't accept login id nor does it ask for password. I do however see a message flash on the screen but it happens too fast.


1) how can I pause this flashed message long enough to read it when attempting to log in?
2) do you think I succeeded in getting into single user mode?
3) if I lose my boot partition and rebuild this, will I lose all the raid data too? I'm not clear on the relationship between my raided drives and the boot partitions. This is a software raid by the way.

Thanks (hope someone is reading this).

It looks like you're at runlevel 3
single user mode won't give you a id/password prompt...
You'll just be at the root prompt # as root user without having to log on.

I've tried "single" and "1" both had same effect when I edited the grub line:
"kernel /vmlinux-2.6.10-1.771_FC2 ro root=LABEL=/ rhgb single"

I don't know why I can't get into single. Now maybe I just need to try knoppix to run e2fsck. But this server doesn't have a dvd/cd reader. All flat cables are being used for the raid5 hard drives. I need to install a dvd/cd reader which will require that I disconnect at least one of the raided drives. The data on the raid5 hard drives isn't critical but I'd like to leave it intact if at all possible.

Can you suggest an approach?

Thanks

I was wrong. When I enter 1, it hanges saying:
INIT: no more processes left in this run level.

If the boot hard drive is completely hosed, is the raid lost too do you think?

Thanks
