[Bug 974218] Re: Bonding configuration change in Precise provides no automatic upgrade path

[Stéphane Graber]

I'm not planning on offering any automated conversion, mostly because
the actual configuration syntax hasn't changed, the ordering change is
there only to make "ifup -a" work and nothing else.

As such any system that was properly configured based on the ifenslave
documentation in past releases will work just as well on 12.04, the
change is that ifenslave now requires you to configure your bond
properly (matching the documentation) or it'll end up waiting for
minutes for things to happen (that never will).

These changes were mentioned in the release notes, blogged about and
referenced everywhere relevant, so I don't think it's worth spending any
extra time dealing with broken configs.

Bug description:
  Hi,

  I use ubuntu in my server, i have two interfaces bonds connected,
  bond0 -> eth2 and eth3
  bond1 -> eth3 and eth4

  In old versions the package ifenslave, my interface bound, works
  without problems

  But in latest version the package ( 1.1.0-19ubuntu5 ) , the interface
  up but not ping.

  Now i use version ifenslave-2.6 (1.1.0-19ubuntu1) and my interfaces
  works without problems.

  My archive :
  /etc/init.d/network/interfaces :

  auto bond0
  iface bond0 inet static
     pre-up ip link set eth2 up
     pre-up ip link set eth3 up
     address 192.168.0.2
     broadcast 192.168.0.255
     post-up ifconfig bond0 mtu 9000
     netmask 255.255.255.0
     slaves eth2 eth3
     bond_mode broadcast
     bond_miimon 100
     bond_updelay 200
     bond_downdelay 500
     bond_usecarrier 1
  auto bond1
  iface bond1 inet static
     broadcast 192.168.1.255
     address 192.168.2.2
     pre-up ip link set eth4 up
     pre-up ip link set eth5 up
     netmask 255.255.255.0
     post-up ifconfig bond1 mtu 9000
     slaves eth4 eth5
     bond_mode broadcast
     bond_miimon 100
