Kernel Panic

[Jees Joy]

Hi Friends,

Please help me in this, I have RHEL ES1; today it crashed and now when it boots it is showing the following error:

umount /inird/proc failed 2
Kernel Panic; no init found. Try passing init=option to kernel


Please help me gurus

That could be caused by several reasons. Cause this was a crash, the first thing to verify is the disk and file system integrity. As you cannot boot from disk, you should start from the CD rom in rescue mode, verify your disks and file systems.

ES1?

anyway, doesn't look good. try booting from the install cd and check if you can mount your filesystems on the disk.

might need to do a fsck.

first suggetion..

Go to rescue mode using the RHEL installation CD with the boot option:

linux rescue

if vg00 not getting mounted automaically.

2.Try to activate the volume groups by running the commands below:

lvmdiskscan
vgchange -ay

3.If vg00 is acitaved Further fsck test can be done using:

tune2fs -l /dev/vg00/lv01 | grep Block

Take note of the Block size.

e2fsck -b -n /dev/vg00/lv01


=================second one== I have not tried this myself===

Your system disk is no longer bootable.

To fix that I have the following suggestions:

use grub in rescue mode to try and re-establish boot capabilities.

This procedure covers two disk mirroing but provides the basics.



1. boot redhat cd 1
2. enter "linux rescue" at isolinux prompt
3. no networking, mount drives
4. at shell prompt, type "grub"
5. find /grub/stage1
6. root (hd0,0)
7. setup (hd0)
8. root (hd1,0)
9. root (hd1)
10. klingon deathgrip

Otherwise back up data and configuration and reinstall the OS.

Thank you friends for that valuable advice; my disk was in a very bad situation to recover; so I had to reinstall it.
