R8168.ko issues / Diskless MD issues
« on: September 12, 2011, 08:57:45 pm »
Hi All,

I am trying to install a diskless MD, which has an on board NIC that needs the R8168 driver.

There are loads of forum posts I've seen and followed to get this running, but after a few minutes, I get the error 'line 1: can't open /tmp/net-eth0.conf' and the kernel panic attempting to kill message. '

The mother board is an A74ML-K with a gigabit Realtek NIC.

A lot of the posts on the forum refer to a folder - '/usr/pluto/diskless/', but there is no folder called diskless in /usr/pluto.

I added a new NIC to the mb, but this didn't allow me to boot over the LAN.

I'm close to tears...

I forgot to include - the onboard Realtek NIC on the mb for the hybrid is also not live. NetworkManager seems to be disabled, however the 2nd NIC works no problem.

Is your onboard nic possibly turned off in bios? Also you may have to swap eth0 and eth1. This can be a problem. There should be a post concerning this in the forum.

Hi. I have 2 MD's with the dreaded 8168 NIC driver issue.

You will find the relevant data to get your new driver complied here:

http://wiki.linuxmce.org/index.php/Realtek_8168

Please do not use the driver I have listed for the 7.10 version. Build a new one using the instructions at the top of the page.

Best Regards,

Seth


Perhaps if I have time this evening, I will post up my 8.10 version of the 8168 driver. Save you some compile time, not that it takes long.

OK, I ended up messing about with too much, so I wiped and started again today.

The problem I have now, with trying to get a network boot, is in the webadmin page, I have the external NIC as eth0 and the internal as eth0:1.

When I try a /etc/init.d/networking restart, the eth0:1 device doesnt get recognised.

Also, in the web admin networking page, eth0 and eth0:1 both have the same mac address.

I am guessing there's an mce file I need to amend somewhere?

Currently, I recieve a DHGCP address on the diskless MD, but then follows a few PXE errors (E11 ARP timeout, E38 TFTP can't open a connection).

SO I have made a couple of changes, and now I tftp boot again, before getting the same error as before -

"IP-Config: no response after 60 secs - giving up
/init: .:line 1: can't open /tmp/net-eth0.conf
[ 63.267760] kernel panic - not syncing: Attemped to kill init!"

try swapping the lines going into your nic cards. Worth a try

I've switched the patch leads into the NICs, and I get no DHCP packets back, so I don't get anywhere with a PXE boot.

The 2nd (external) NIC is playing up, and from another thread on the net, I've seen a reference to a /etc/dhcp3/dhcpd.conf file, which references fugue.com, so I don't knwo if the 2nd NIC needs to be working fully?

I'm from the networking side of life, so linux isn't a strong (or even weak) point. Big learning curve since starting this!

Edit: I have perhaps jumped the gun with this, and it's not an R8169 issue? I'm not sure at all...

So, it does seem that I need to r8169/8111 driver for this card, however I can see in the verbose during the tftpboot that there's mention of the rtl8139 driver.

The rtl8139 is for 10/100 only, and this is definately a gigabit NIC.

How would I go about forcing the 8169/8111 driver onto the MD during boot?

You can grab the latest Realtek driver for that NIC from the RealTek website.   You'll have to follow the instructions in http://wiki.linuxmce.org/index.php/Unrecognized_NIC   and this http://wiki.linuxmce.org/index.php/Realtek_8168..
This all gets done from your CORE/Hybrid machine... you'll have to create the initial MD via the admin web page > Media Directors..  once the directory under /usr/pluto/diskless/xx   (xx is the MD number) is created, you'll have to follow the instructions on the Unrecognized NIC link  and/or  the Realtek link

I've created the MD as a diskless MD in the web admin page, but when I look in /usr/pluto/ there is no folder called diskless?

I've rebooted and the MD is definitely there, and set up as diskless. It has the device number of #34, but still does not show in dolphin.  ???

Don't do anything in web admin, that's not necessary.

Did you do something simliar to this as per the link I posted earlier...

Code: [Select]
cp r8168.ko /lib/modules/2.6.22-14-generic/kernel/drivers/net/
mv /lib/modules/2.6.22-14-generic/kernel/drivers/net/r8169.ko /lib/modules/2.6.22-14-generic/kernel/drivers/net/r8169.bak
depmod -a
/usr/pluto/bin/Diskless_BuildDefaultImage.sh

...before trying to reboot the MD again?

Hi, sorry for the delay - I had a short break away from London.

I did run what you suggested. Everything ran OK, but again I have a line telling me 'etho: link down' on the MD after it has loaded some things from the core.

I'm wondering if it would be easier to have this running with a HDD and kubuntu installed... Would I be right?
