CentOS - Feb 2007 - kernel 2.6.9-42.0.8.EL error while booting - CentOS 4.4

Hi ,

I am ruuning Senmail with MailScanner on CentOS 4.4. It has updated to
kernel 2.6.9-42.0.8.EL from its past kernel 2.6.9-42.0.3.EL.

Now the Server can not boot up and gives the below error.

  mkrootdev: label / not found
  Mounting root filesystem
  mount: error 2 mouting ext3
  switchroot: mount failed: 22
  Kernel panic - not syncing: Attempted to kill init!

But I can boot up from its last kernel 2.6.9-42.0.3.EL. I have booted it up
from that kernel.

But I wnat to rectify that new kernel error in order to boot from that
kernel.

Help needed.

Thank you

The new kernel seems to have problems picking up the filesystem label.

I think as a work around you can change the grub.conf to use the 
/dev/xxx instead of the disk label.

I have already set it.

pls  see below


title CentOS (2.6.9-42.0.8.EL)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-42.0.8.EL ro root=LABEL=/ rhgb quiet
        initrd /initrd-2.6.9-42.0.8.EL.img

i removed .ko from all and then gave the below error.

[root at gateway etc]# cd /boot/

[root at gateway boot]# mkinitrd --with=sd_mod --with=scsi_mod with=ata_piix
--with=libata /root/initrd-2.6.9-42.0.8.EL.img 2.6.9-42.0.8.EL
usage: mkinitrd [--version] [-v] [-f] [--preload <module>]
       [--omit-scsi-modules] [--omit-raid-modules] [--omit-lvm-modules]
       [--with=<module>] [--image-version] [--fstab=<fstab>]
[--nocompress]
       [--builtin=<module>] [--nopivot] <initrd-image>
<kernel-version>

       (ex: mkinitrd /boot/initrd-2.2.5-15.img 2.2.5-15)

I think path is not set properly.

Thanks. I did it.

[root at gateway boot]# mkinitrd --with=sd_mod --with=scsi_mod --with=ata_piix
--with=libata /root/initrd-2.6.9-42.0.8.EL.img 2.6.9-42.0.8.EL

this  time it worked.

now it shows new modules.  pls see below.

[root at gateway boot]# gunzip -cd initrd-2.6.9-42.0.8.EL.img |cpio -t
.
etc
etc/udev
etc/udev/udev.conf
init
lib
lib/libata.ko
lib/jbd.ko
lib/ext3.ko
lib/sd_mod.ko
lib/scsi_mod.ko
lib/ata_piix.ko
proc
loopfs
bin
bin/udevstart
bin/insmod
bin/udev
bin/hotplug
bin/nash
bin/modprobe
sbin
dev
dev/console
dev/null
dev/tty1
dev/systty
dev/tty2
dev/ram
dev/tty3
dev/tty4
sysroot
sys
2147 blocks


then I did the below steps.

[root at gateway etc]# cd /boot/

[root at gateway boot]# cp initrd-2.6.9-42.0.8.EL.img
initrd-2.6.9-42.0.8.EL.img.8feb2007

[root at gateway boot]# cd

[root at gateway ~]# cp initrd-2.6.9-42.0.8.EL.img /boot/
cp: overwrite `/boot/initrd-2.6.9-42.0.8.EL.img'? y

Now it has newly rebiult /boot/initrd-2.6.9-42.0.8.EL.img.

Now I only need to restart the Server. To do that, It takes some time as
users are getting emails .

After the reboot, I will let you know.

THNAK YOU VERY MUCH.
