Ethernet Bonding - Active Load Balancing


This has got me stumped!!

I'm trying to setup Active Load Balancing (mode=6) on bond0. It works great... until I reboot! Then the usual set of problems attack me. (acpi, set mac addr, etc etc)

Hardware: 2 NICs, (e100, tulip)
Software: CentOS 4.4 / RHEL 4 u 4 ES

[root@www ~]# lspci
00:02.0 Ethernet controller: Intel Corporation 82557/8/9 [Ethernet Pro 100] (rev 08)
03:06.0 Ethernet controller: Lite-On Communications Inc LNE100TX (rev 21)


The modprobe.conf is setup as usual. I've swapped them (eth0/1) back n forth and rebooted a few times. No changes.

[root@www ~]# cat /etc/modprobe.conf
alias eth0 tulip
alias eth1 e100
alias bond0 bonding
options bond0 mode=balance-alb miimon=100


With mode=balance-alb I get an error about setting the mac address in the device.

With other modes, I get a whole bunch of errors, which almost cripple the machine.


Any suggestions??

I fought with FC4/FC5 for a couple of months. Mode 4 and below I could get to work fine but mode 5 + 6 I ran into what you are. I suspect that the drivers/card design predates mode 5 + 6 and they just cannot handle it. My solution was Ebay. I picked up a couple of 3com GigE ethernet cards for $20 ea with shipping. They are happy campers.

I found my files on bonding.

In modeprobe.conf:

alias bond0 bonding
options bond0 mode=balance-alb miimon=100 max_bonds=2


In ifcfg-bond0:

DEVICE=bond0
BOOTPROTO=dhcp
TYPE=Bonding
ONBOOT=yes
USERCTL=no
PEERDNS=yes


In ifcfg-eht0&1:

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
PEERDNS=yes
MASTER=bond0
SLAVE=yes
IPV6INIT=no


Hope this helps

My config files look the same.

I think my problem is with this "silly e100" onboard NIC. These are on older Compaq Proliant DL380's. (We're talkin p3-800mhz era). I don't think the APIC is up to par either. So I'm giving up on this, (for now).
