make boot cdrom pb:

[Jean-Paul BALOCHE]

Hi,

I contact the mailling list because I'm steel unable to boot on nfsroot
with a cdrom.
Here is the error message when I'm booting from cdrom with dhcp,nfs choice :
Begin: Mounting root file system
/init: .:150: Can't open file system... ...
kernel panic - not syncing: Attempetd to kill init!
I've got the same error message when I'm choosing demohost installation
from the cdrom.

Here is my configuration :
*** /etc/exports :
/srv/fai/config 192.168.1.0/24(async,ro,no_subtree_check)
/srv/fai/nfsroot 192.168.1.0/24(async,ro,no_subtree_check,no_root_squash)

*** /etc/dhcp3/dhcpd.conf :
#deny unknown-clients;
option dhcp-max-message-size 2048;
use-host-decl-names on;
subnet 192.168.1.0 netmask 255.255.255.0 {
   range 192.168.1.234 192.168.1.240;
   option routers 192.168.1.2;
   option domain-name-servers 192.168.1.2;
   option time-servers 192.168.1.2;
   option ntp-servers 192.168.1.2;
   server-name faiv4;
   filename "pxelinux.0";
}

*** /etc/fai/menu.lst :
title boot from local disk
rootnoverify (hd0)
chainloader +1
title Fully Automatic Installation - dhcp, nfsroot
kernel /boot/vmlinuz ip=dhcp root=/dev/nfs
nfsroot=192.168.1.204:/srv/fai/nfsroot boot=live

initrd /boot/initrd.img

kernel /boot/vmlinuz boot=live FAI_FLAGS="verbose,createvt"
FAI_ACTION=install ip=192.168.1.1:::::eth0:off hostname=demohost
initrd /boot/initrd.img

*** here is the command I use to create the cdrom :
fai-cd -f -m /srv/fai/debmirror/ cd_boot_4.1.6.iso

*** When I look into the faiserver logs, I have nothing in syslog
regarding dhcp or nfs mount whereas I know they works because I'm able to
have a dhcp lease with another computer and I can mount nfs directory with
mount -t nfs 192.168.1.204:/srv/fai/nfsroot /tmp/temp

So, I don't understand what's going on. Have you got an idea ?

thanks for your help.
