Description of problem: According to bonding.txt, you are supposed to be able to load multiple instances of the bonding module to allow multiple bonding interfaces to be declared with different parameters. The documention says you should setup an alias in modprobe.conf as follows: <snip /etc/modprobe.conf> alias bond0 bonding options bond0 -o bonding0 miimon=100 alias bond1 bonding options bond1 -o bonding1 miimon=100 </snip /etc/modprobe.conf> However, when I attempt to startup networking with both a bond0 and a bond1 interface declared I get the error message "bonding: Unknown parameter '-o'" This suggests to me that either there is some sort of error in the bonding kernel module that is failing to recognise the '-o' parameter, or that the bonding documentation is incorrect. I have tested a multiple load under RedHat Enterprise 3 Update 5 and it works as expected, loading the module twice as bonding0 and bonding1 (Seen with an lsmod). Version-Release number of selected component (if applicable): kernel-2.6.9- 22.0.1.EL How reproducible: Every Time Steps to Reproduce: 1. Declare two different bonded interfaces (bond0 and bond1) 2. Modify modprobe.conf as recommended by bonding.txt and as shown in the bug description. 3. Try to startup/restart the network and watch for the "Unknown Parameter '- o'" error Actual results: The bonding driver loads onces as 'bonding' and you get a 'bond0' interface but no 'bond1' inderface showing listed with an ifconfig. An 'lsmod' shows that the bonding diver has loaded once as 'bonding' rather than loading twice as 'bonding0' and 'bonding1' Expected results: The bonding module should have loaded itself twice and given me two bonded network interfaces. Additional info:
The kernel docs for bonding are being update as part of U3. In the meantime, you should modify modprobe.conf to look more like this: install bond0 /sbin/modprobe --ignore-install -o bonding0 bonding miimon=100 remove bond0 /sbin/modprobe -r --ignore-remove bonding0 install bond1 /sbin/modprobe --ignore-install -o bonding1 bonding miimon=100 remove bond1 /sbin/modprobe -r --ignore-remove bonding1 Please give that a try and let me know if it works for you...thanks!
Yes, thank you. This works much better thank you.
