[Bug 881379] Re: ifenslave fails to bring up bond link

[Alexandr Novel]

Either software is wrong or something else.
Should there something else be configured on the switch besides LACP?

Title:
  ifenslave fails to bring up bond link

Status in “ifenslave-2.6” package in Ubuntu:
  Fix Released

Bug description:
  After upgrade of ubuntu-server from maveric to oneiric, a bond link
  failed to automatically get up on system startup.

  The network is configured as follows and the configuration was not
  changed:

  root at srv2:/etc/network/if-pre-up.d# cat /etc/network/interfaces 
  # This file describes the network interfaces available on your system
  # and how to activate them. For more information, see interfaces(5).

  # The loopback network interface
  auto lo
  iface lo inet loopback

  # The primary network interface
  auto bond0
  iface bond0 inet manual
  	slaves eth0 eth1
  	bond_mode 4
  	bond_miimon 100
  	bond_downdelay 200
  	bond_updelay 200
  	bond_lacp_rate 1

  auto bond0.904
  iface bond0.904 inet manual

  auto vmbr0
  iface vmbr0 inet static
          bridge_ports bond0.904
          bridge_stp off 
  	address 192.168.220.2
  	netmask 255.255.255.0
  	network 192.168.220.0
  	broadcast 192.168.220.255
  	gateway 192.168.220.254

  
  The simple solution is to change line order of "enslave_slaves" in /etc/network/if-pre-up.d/ifenslave -- se attached diff
