NFS boot problem

[Skywalker]

Guys,

I am trying to boot my pogoplug using NFS. It is almost working, but apparently something goes wrong during booting:

Code:

                                                                             
U-Boot 1.1.4

Doesnt look to bad: but I cant do anything, I dont get a prompt.
my exports file:

Code:

/sheevaplug/ubuntu 192.168.178.20/30(rw,sync,no_root_squash)
/tftpboot 192.168.178.20/30(rw,sync,no_root_squash)

this uimage is in /tftpboot
and I untarred the full directory structure of ubuntu-9.04.tar.gz to /sheevaplug/ubuntu (so not the JFFS file but the directories)

How can I be sure he is using the file system from the NFS server and not from the pogoplug itself ? Or am i using an incompatible set of kernel image and ubuntu distribution ?

Next step would be too flash the pogoplug with the kernel and ubuntu version (this time the JFFS file)

Kind regards,

first u can see on your log that it boot from NFS"eth0: link up, full duplex, speed 100 Mbps
Looking up port of RPC 100005/1 on 192.168.178.21
VFS: Mounted root (nfs filesystem).
Freeing init memory: 124K
 * Setting preliminary keymap...           

I think your problem is that when u boot from NFS u should disbale dhcp on your boot scripts...

Thank you,

How can I do this ?
I also dont understand (and I would like to understand it), why I could get in trouble with DHCP.

Kind regards,

Luke

In uboot you give the plug 192.168.178.23 for an ip address. 

In your /etc/exports you allow addresses of the range 192.168.178.20/30 (192.168.178.20 - 192.168.178.23) to access your nfs server.

It looks like it is working fine up until it is initializing the Ethernet interface.

If your /etc/network/interfaces is causes the plug to get an address range other than (192.168.178.20 - 192.168.178.23) when the ethernet interface is initialized then your nfs server will no longer let it access the file system.

Try setting a static ip address in /etc/network/interfaces or make sure your dhcp server will assign the plug a address in the range allowed by your nfs server.

example of a static address in /etc/network/interfaces:

Code:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
auto eth0
iface eth0 inet static
        address 192.168.178.21
        netmask 255.255.255.0
        network 192.168.178.0
        broadcast 192.168.178.255
        gateway 192.168.178.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 192.168.178.1

Hi Kilowatt,

I tried what you proposed: I changed /etc/network/interfaces in the /sheevaplug/ubuntu/ directory, but I took address 23 instead of 21
Unfortunately it didn't change anything.
I still wonder how I could have a problem with DHCP: my router is assigning an address based on the MAC address, so every time I login with the Plug I always get the same address (Thats what I understand from my router listing).
Kind regards,

Luke

[kilowatt]

You should be able to use DHCP as long as the router is configured to give out the correct address. 

Can you tell from the router logs if it is getting the DHCP request from the plug?

Do you have more than one plug?  I found that if I booted a second plug using the file system I had previously used to boot another plug it confused the network settings.

udev enters a rule in /etc/udev/rules.d/70-persistent-net.rules based on the mac address so that the same device is always associated with a particular network interface.  So when I booted the first plug it entered a rule associating eth0 with the mac address of that plug.  When I booted the second plug it created a rule and assigned eth1 to the Ethernet interface since it had a different mac address.  If this happens you can fix it by just deleteing the rules from /etc/udev/rules.d/70-persistent-net.rules and it will assign eth0 to the first network interface it finds.

Pls try disabling IP configuration at all and give it a try, dont use dhcp and dont use setting static IP, leave the IP that was assigned by U-Boot through the command line.
