Bonding issues with more than 2 Bonds in different modes

dsf · 2009-12-23 12:47:59

Hi there!!

I found using Arch with bonding.ko driver that have some issues regarding having 4 adapters with 2 bondings in different modes.

The scenario:
bond0 : eth0 eth1 mode failover
bond1: eth2 eth3 mode alb

The problem:
All bond interfaces stays in failover mode.

The solution:
# modprobe.conf file #
options bonding miimon=100 max_bonds=2
alias bond0 bonding
alias bond1 bonding

Now the changes if Arch People agrees.:D
on file /etc/conf.d/bonding

add a new VARIABLE called

mod_bond0="fault-tolerance"
mod_bond1=""

and i changed the /etc/rc.d/network script a little
on function bond_up

for ifline in ${BOND_INTERFACES[@]}; do
                if [ "$ifline" = "${ifline#!}" ]; then
                        eval bondcfg="\$bond_${ifline}"
                        eval bondmod="\$mod_${ifline}"  ### Add this line to get bonding mode #########
                        if [ -n "${bondcfg}" ]; then
                                /sbin/ifenslave $ifline $bondcfg || error=1
                        fi
                        ####  adding this condition to apply mode to bonding adapter #################
                        if [ -n "${bondmod}" ]; then
                                /sbin/ifconfig $ifline down || error=1
                                /bin/echo $bondmod > /sys/class/net/$ifline/bonding/mode || error=1
                                /sbin/ifconfig $ifline up || error=1
                        fi
                fi
        done

on function bond_down

for ifline in ${BOND_INTERFACES[@]}; do
                if [ "$ifline" = "${ifline#!}" ]; then
                        eval bondcfg="\$bond_${ifline}"
                        /sbin/ifenslave -d $ifline $bondcfg || error=1
                        /sbin/ifconfig $ifline down || error=1
                fi
        done

This code solve my problem, and works very well in my ArchLinux, my suggestion is if it is possible to include this changes in next initscripts package.
Cheers,
Daniel
