Re: [Devil-Linux-discuss] multiple bonds devices

[Serge L. <ser...@gm...>]

Hello Motycka,

It looks like it's not possible to configure it by network scripts. I'm not sure 
that it's clear how to fix - we need some time to think.

As a workaround (ugly, I know) you can change the mode for already created bond, 
i.e.
for bond0 - MODULE_OPTS="max_bonds=2 mode=2 miimon=100"

---------------------------------------------------
root@dl1:/shm/etc/sysconfig/nic # grep -v "^#" ifcfg-bond0
DHCP=no
ONBOOT=yes
DEVICE=bond0
MODULE=bonding
BONDING_MASTER=yes
BONDING_SLAVES='eth0 eth1'
MODULE_OPTS='max_bonds=2 mode=2 miimon=100'

---------------------------------------------------

then  add the line to the end of ifcfg-bond1:

echo "4" > /sys/devices/virtual/net/bond1/bonding/mode

---------------------------------------------------
root@dl1:/shm/etc/sysconfig/nic # grep -v "^#" ifcfg-bond1
DHCP=no
ONBOOT=yes
DEVICE=bond1
MODULE=bonding
BONDING_MASTER=yes
BONDING_SLAVES='eth2 eth3'
MODULE_OPTS=''

echo "4" > /sys/devices/virtual/net/bond1/bonding/mode
---------------------------------------------------


The result:

root@dl1:/shm/etc/sysconfig/nic # for i in 0 1 ; do echo bond$i ;  cat 
/proc/net/bonding/bond$i | grep "Bonding Mode"; done
bond0
Bonding Mode: load balancing (xor)
bond1
Bonding Mode: IEEE 802.3ad Dynamic link aggregation


Could you please also submit a bug to not forget about proper fixing?
