netbooting problems

Tags:

Hi everybody
i'm configuring a netbooting environment on a small
cluster of 4 machines.
i don't use any netbooting tools. i have a DHCP server
and a Boot server (each of them on and independent
machine).
while booting the client machine, i got that error:
pivot_root: no such file or directory
chroot: cannot run command '/sbin/init': No such file
or directory
kernel panic: Attempted to kill init!

any help

thanks in advance

frankly, I'm a newb to netbooting as well, but you're problem seems
pretty straightforward. It looks like your initrd can't find / to
transfer control to. Where have you put / and where does the initrd
expect to find it?

the / is on the root server under directory /netboot/.
here is a copy of my pxelinux.cfg file, which tells
where to find the /

default debian-sarge-3.1

label debian-sarge-3.1
kernel debian-sarge-3.1/vmlinuz
append initrd=debian-sarge-3.1/initrd.img
root=/dev/nfs ip=dhcp NFSROOT=172.22.0.10:/netboot/
ETHERNET=eth0

thanks for ur reply

Yours

Heba

Heba, please reply to the list only as I subscribe to the list. Also,
it allows others to assist you. As I said, I'm a newbie to netbooting
and don't know a thing about it. I was merely trying to point out that
your kernel wasn't finding / and to look at that issue.

I have cc'd the list on this so that maybe others can pitch in.

I don't know what to look for here, but something in this setup is
causing the kernel to not find /. best of luck
