kernel panic bin/sh no such file or dir

send2rawat · 06-27-2010, 11:18 PM

while booting my linux system I'm Getting ..

exec of init (/sbin/init) failed!!!: 2
umount /inited/dev failed: 2
kernel panic - not syncing: Attemped to kill init!

and in rescue mode
I checked all things seems to be ok ... fstab, grub.conf, initrd file.
but when i do chroot /mnt/sysimage it gives

chroot: cannot execute /bin/sh: No such file or directory

I've also checked with reinstalling grub and making ld.so.cache again but doesn't work.
pls suggest what are the possible solutions.

Have you changed any kernel or initrds lately.. although not being able to chroot should partly cast aside this assumption.

This sounds like a fs error possibly.. how about that.. what fs is it.. ext3/4?

Have you fsck -VC it?

Was it working before.. because it sounds like something got trashed (or deleted).. but since you can't even chroot.. I suspect a fs error.. but I could be wrong.

/mnt/sysimage is mainly used for installs, unless you have set it up that way.

/ is not where you think it is. So your line
kernel somekernel root=somedrive is wrong,

When the kernel is loaded, the system mounts / and then runs /sbin/init. Now it is finding what you call / but it is not /, because /sbin/init or /bin/sh cannot be found. Post your grub.conf and we can get you out of this.

here is grub.conf

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux AS (2.6.9-42.ELsmp)
root (hd0,0)
kernel /vmlinuz-2.6.9-42.ELsmp ro root=LABEL=/1 rhgb quiet
initrd /initrd-2.6.9-42.ELsmp.img
title Red Hat Enterprise Linux AS-up (2.6.9-42.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-42.EL ro root=LABEL=/1 rhgb quiet
initrd /initrd-2.6.9-42.EL.img

I dont think there is something wrong in grub.conf because I've already matched with other servers.

I've had trouble with those label things before. Do you know what partition / is on? Edit that line; when grub comes up hit e twice, and you should get an editor of sorts. change that to root=/dev/sdax where x is the number of your / partition. Return to finish, and b to boot it.

But I m not able to understand why it is giving
chroot: cannot execute /bin/sh: No such file or directory

is there any prob in bin/sh ??

checked with root=/dev/sda3 (my / drive) in grub.conf .. but still giving same error ..
I tried with making new initrd file but it says /lib/module .. no such file or dir.
I tried copying bash also (may be the bash giving the error ) ..
cp /usr/bin/bash /mnt/sysimage/bin/bash .. but was not useful.

Is it looking for /bin/bash in the initrd? or when exactly does it ask for /bin/bash?

send2rawat · 06-30-2010, 03:39 AM

No I just googled it .. copying
It is just saying
chroot cannot execute /bin/sh: No such file or directory

while booting it gives
exec of init (/sbin/init) failed!!!: 2
umount /inited/dev failed: 2
kernel panic - not syncing: Attemped to kill init!

That's your latest post. "umount /inited/dev failed" looks like a typo has got in - inited??

In post #3, I pointed out

Because of this, it can't find /bin/sh or /sbin/init. get rid of that label= thing in grub.conf, because you can have 2 partitions called label=/1 and then the fun really starts. Believe me, I've had it!
