Channel Bonding Problem

Ferdi Castro — Wed, 11 Oct 2006 06:08:58 GMT

Hi,
I tried to create bond configuration---ifcfg-bond0, then modules.conf.
i tried to check if the module using lsmod but it was not there. I tried to do insmod bond0 and gives me the error... it says no such file or directory and when i command rmmod bond0 Module bond0 does not exist in /proc/modules.
I understand i lack this module. How can I introduce this module in my linux box?
thanks

Lets start with which version of linux you're runing.

Then tell us which network devices you're using along with the drivers.

And the hardware platform would help as well.

These are my bonding files off a Redhat AS 4 server. If you change /etc/modprobe.conf be sure to run a mkinitrd and reboot. I'm showing "bonding" as the kernel module that's loaded on Redhat AS 4.0, not "bond0"

The module is "bonding", not bond0
Create an alias in /etc/modprobe.conf

Thanks for the reply.
how is this mkinitrd command exectuted.
i did was
mkinitrd -v -f -preload
then reboot
unfortunately bond is still not there.

I have some few questions
1) does bonding need a driver? How can I check that I have bonding through command line?
2) Suppose I don't have the driver? Is it free to download

Thanks.

mkinitrd is executed using the output from the command "uname -r"

Example
>uname -r
2.6.9-34.0.1.ELsmp
>mkinitrd -f /boot/initrd-2.6.9-34.0.1.ELsmp.img 2.6.9-34.0.1.ELsmp

or

>mkinitrd -f /boot/initrd-`uname -r`.img `uname -r`

After doing mkinitrd as suggested by Eric. problem still occurs
Error encountered:
/sbin/modprobe device bond0 does not seem to be present.
what could be the problem here? is it a driver?
when i do lsmod bonding is not there.
PS. Im using RH 4. thanks.

if you do:
insmod bonding
lsmod |grep bonding

what's the output?

Re: Channel Bonding Problem

Ferdi Castro — Sun, 15 Oct 2006 04:44:10 GMT

outout: insmod can't read 'bonding' no such file or directory
lsmod | grep bonding doesn't have any output

Re: Channel Bonding Problem

Do you have a directory called "bonding" when you perform this command

ls -l /lib/modules/`uname -r`/kernel/drivers/net
