Hi, I have several servers using the bond configuration on 8.04. I found the most effective way to enable this was to do the modprobe configuration (though the URL you posted has better instructions than I did), then I make the following in the interfaces file:
auto bond0 iface bond0 inet static address 10.10.10.10 netmask 255.255.255.0 gateway 10.10.10.1 post-up ifenslave bond0 eth0 eth1 I originally had the line: post-up ifenslave bond0 eth0 eth1 replaced with: slaves eth0 eth1 However did not get consistent operations. I am using mode 1 for all teams. Thanks. Andrew. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Serge van Ginderachter Sent: 18 June 2009 10:43 To: ubuntu-server Subject: Interface bonding Hi all, I have been following https://help.ubuntu.com/community/UbuntuBonding to set up a bond of two network interfaces, and it seems to me this documentatuoin has certain flaws. No problem with the Module Alias Configuration. AFAIK this configuration will already make sure that the bonding module is probed and loaded. I then have some remarks on the interface configuration part. * loading and unloading the module through pre-up and post-down statements is not necessary, as the loading already happens in de modproe.d config, and might even be unwanted in tha case were one has multiple bonds configured, which would (try to) unload the module after bringing one bond down, whilst it still being in use for another one. * configuring the bond (ifenslave bond0 eth1 eth2) in the (post-)up statements didn't work for me: it seemed (post-)up happens after configuring an ip, but at that time the bond is not configured yet, and configuring the ip results in an error. I'm not totally sure if this is eneral logical behaviour or if I just messed something up at one point in my config trial and error. * finally, this howto does not mention the by far easier method explained in /usr/share/doc/ifenslave-2.6/README.Debian: it's just enough to use the "slaves eth0 eth1" in the iface bond0 stanza It might be interesting to have those remarks reviewed, to check if my evaluation is correct.
