Regarding the bug in squeeze that tom mentions: i checked with the debian maintainer of the module-init-tools package. he had not heared about that bug, and reports that he himself runs bonded interfaces on squeeze without problems.

There is a bug in some 2.6.26 and 2.6.32 kernels with bonding driver. I found it in Xen kernels.

If you want two bond interfaces the option: modprobe bonding max_bonds=2
does not work

Instead of 2 intrerfaces 3 or 4 it works! i.e: modprobe bonding max_bonds=3

Its an annoying bug.

There is a bug in Debian Squeeze which cause bonding not to boot up.
module-init-tools package is buggy, do not upgrade Lenny to Squeeze if You use bonding until this bug is fixed.

Currently, I’m building a test beowulf cluster in virtual environment just for my college lesson. Squeeze was needed becouse other bug (in kernel-package) caused that I was unable to build my own kernel.

I used sucessfuly bonding before on:
Debian Etch - just for load balancing 2 x 100Mbit cards in two machines hosting Samba and service tools
Debian Lenny - for LAN interface for double speed (2x1Gbps) in a routing server (it’s a gateway for LAN). I have static routes.
Ausidada: I’m working on same problem. Have to recompile kernel with “dead gateway detection” and routing patches. Next have to create static tables. There is no way to create backup for ISP using bonding. It’s good for connection beteween servers or for LAN.

ow do I create backup bonding between NIC1 & NIC2 for gateway
Forget it. In real world you can’t do this. You need to use dynamic routing or floating static routes

Hi,
I have NIC0 (local network), NIC1 (ISP provider 1) and NIC2 (ISP provider 2 - for backup), how do I create backup bonding between NIC1 & NIC2 for gateway. Any help on this will be much appreciated.

I want to create two separate bonding devices with two slaves each

The default max bonding device is 1. See . Try setting it to 2 or more.

Can you provide an example of /etc/network/interfaces with two IP addresses on the same bonding interface ?
Thanks

And I have need for an active failover bond consisting of two load balanced bonds. I fear bonding only supports enslaving of “real” eth interfaces, though. Has anobody tried that?

This howto is incomplete. What if I have 4 NICs and I want to create two separate bonding devices with two slaves each ?

As far as I have tried, I manage to get the bond0 interface up but I can not get bond1 up using /etc/network/interfaces.
