CentOS - Kernal Panic -not syncing Attempted to Kill init
 

HI I have a Dell 1900 running CentOS 2.6.18-194.11.3.el5.centos.plus.

I was unable to access the server and had to reboot it. When the server was booting after the Grub, it errored out with

Kernal Panic -not syncing Attempted to Kill init!!
exec of init (/sbin/init/) failed No such directory

I reboot into the recuse mode from the CD and when looking for the installed OS.
I got an error like this

Found OS but with errors. Mounting part or all of your system at /mnt/sysimage.. something of the sort. I've run fsk -y on the /boot and root drives and rebooted but still the same issues.

Here is my grub.conf:

# NOTICE: You have a /boot partition. This means that

Here is my fstab:

sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
LABEL=SWAP-sda2 swap swap defaults 0 0
/dev/sda2 /mirror ext3 defaults 0 0


I've also tried to chroot /mnt/sysimage /bin/bash but I get and error of no such file or directory
I can see my files under /mnt/sysimage and everything seems to be intact.

Thanks in advance!!

Suspect some kind of filesystem corruption or partition damage. Possibly even Hard Drive failure?
When in Rescue mode (from the CD) - Choose Continue.
Before running 'chroot /mnt/sysimage'
Run:
# df -h
# fdisk -l

Please paste the output here so we can help figure it out.

Try to look at smartd logs or what ever hwmonitor you might have for your drives. I does sound like file system corruption. But indeed you could have a failed hd.

Thank guys! I will post the outputs or fdisk -l and df -h a bit later today.

-R

Well, your root & boot partitions are still mounting at least in rescue mode. There does appear to be a partition missing, judging from ur fstab.

You could not chroot into /mnt/sysimage?
if so, look inside /mnt/sysimage. Check if /mnt/sysimage/bin/bash is actually there, what's it's permissions.

Look in /var/log/messages. Look for any errors at around the time the trouble started.
Look in /var/log/dmesg for any hardware errors.

Sorry for the late response, I've been out of town but I'll take a look at it today and get back to you.

Thanks for the assistance!


Update: I still can't chroot into /mnt/sysimage. I checked the permissions of /mnt/sysimage/bin/bash and its root.root
