I think you are trying to use a deprecated and unsupported means of bringing up the bonded interface in /etc/network/interfaces. As explained in /usr/share/doc/ifenslave-2.6/README.Debian.gz, the bonding interface needs to be brought up via stanzas for each of the physical interfaces. For example:
iface bond0 inet static bond_slaves none bond_primary eth2 bond_mode 1 bond_arp_interval 2000 bond_arp_ip_target 192.168.100.1 address 192.168.100.50 netmask 255.255.255.192 gateway 192.168.100.1 auto eth0 iface eth0 inet manual bond_primary eth2 bond_master bond0 auto eth2 iface eth2 inet manual bond_primary eth2 bond_master bond0 If the example you provided was working before as a complete /etc/network/interfaces, I think it did so by chance alone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/823366 Title: bond_primary is ignored in /etc/network/interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifenslave-2.6/+bug/823366/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
