Just confirming Neil Wilson's findings. I had the "no bond connection upon reboot" issue and was using the non hot-plug configuration method. I switched to hot-plug and the problem was sorted.
Description: Ubuntu 10.04.2 LTS --- current config ---- # bond/trunk eth0-1 auto bond0 iface bond0 inet static address 192.168.1.94 netmask 255.255.255.0 gateway 192.168.1.1 # bond-slaves eth0 eth1 bond-slaves none bond-mode 802.3ad bond-miimon 100 # enslave eth0-1 auto eth0 iface eth0 inet manual bond-master bond0 auto eth1 iface eth1 inet manual bond-master bond0 -------------- Previous config had bond-slaves eth0 eth1 as comment shows and both bond-master lines on eth0 and eth1 were non-existent. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/482419 Title: 802.3ad interface bonding fails if started too early -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
