I have a diskless box I'm trying to boot by PXE. I've configured a
dhcpd, and I've got the loader loading by tftp and then the kernel
booting by NFS fine. I'm having a little trouble persuading the kernel
to mount the root filesystem, though. My dhcpd.conf says:
option domain-name "localnet";
option routers 192.168.64.1;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.64.255;
option domain-name-servers 192.168.64.2;
server-name "DHCPserver";
server-identifier 192.168.64.2;
default-lease-time 120;
max-lease-time 120;
subnet 192.168.64.0 netmask 255.255.255.0 {
range 192.168.64.10 192.168.64.30;
}
host diskless {
hardware ethernet 0:90:27:f1:4c:9b;
filename "/boot/pxeboot";
fixed-address 192.168.64.20;
next-server 192.168.64.2;
option root-path "/";
}
(I know that mounting the root filesystem of another machine as the
diskless box's root will produce a somewhat broken setup, but I really
just want to see the thing get as far as the init scripts before I go
away and set things up properly.)
As the kernel boots, it says:
bootpc_init: using network interface 'fxp0'
fxp0: starting DAD for fe80:0001::0290:27ff:fef1:4c9b
Bootpc testing starting
bootpc hw address is 0:90:27:f1:4c:9b
My ip address is 192.168.64.20
Server ip address is 192.168.64.2
Gateway ip address is 0.0.0.0
Server name is DHCPserver
boot file is /boot/pxeboot
Ignoring field type 54
Subnet mask is 255.255.255.0
Router is 192.168.64.1
Ignoring field type 15
panic: Failed to set rootfs to /
What am I doing wrong here? Can I set some parameter in the loader that
tells the kernel which server and filesystem to mount, so it doesn't
have to do a bootp (when a dhcp has already happened earlier in the boot
sequence)?
Thanks for any help.
Chris.
