I have a server with 4 interfaces(eno1..4) bonded together. So far so good.

With the VLANS in the config, when I start networking services, it return an error:

$ service networking status
● networking.service - Raise network interfaces
   Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Mon 2017-09-04 11:04:11 -03; 7min ago

 Main PID: 2180 (code=exited, status=1/FAILURE)

If I comment auto bond0.20/30 and restart networking, I got no error. But If I ifup bond0 20, I got an error:

$ ifup bond0.20
RTNETLINK answers: File exists
ifup: failed to bring up bond0.20

Here is my conf:

EDIT

My new setup with bridges:

    slaves eno1 eno2
    bond-mode 802.3ad

auto bond0.30

It goes up, but return an error, show the service networking status isn't clean.

  • You need to find out where systemd is logging what's actually happened, as it doesn't show the issue here. It's likely accessed via some invocation of journald however I'm not a systemd user so can't advise further. – djsmiley2kStaysInside Sep 4 '17 at 14:19
  • The problem is that when it tries to up the bond0.20, it says it already exists, and it does. I changed my setup a bit, to add bridges, as I'll need them in the KVM. – 0x3333 Sep 4 '17 at 22:37

Well, what I did was:

Remove auto from vlans, added the following to the bond0:

 pre-up vconfig add bond0 20; vconfig add bond0 30

This way the vlans are created before the bond0 interface goes up.

Final config file:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# Bonding interfaces

allow-hotplug eno1
iface eno1 inet manual

allow-hotplug eno2
iface eno2 inet manual

allow-hotplug eno3
iface eno3 inet manual

allow-hotplug eno4
iface eno4 inet manual

# Main bonding interface
auto bond0
iface bond0 inet static
        address 10.10.0.1
        gateway 10.10.0.254

        dns-nameservers 10.10.0.254
        dns-search mydomain.local
        bond-mode 802.3ad
        bond-miimon 100

        bond-slaves eno1 eno2 eno3 eno4
        pre-up vconfig add bond0 20; vconfig add bond0 30

iface bond0.20 inet static
        address 10.20.0.1
        gateway 10.20.0.254
        netmask 255.255.255.0

iface bond0.30 inet static

        gateway 10.30.0.254

  • This solved the bond + vlan problem. But now I have bridges and it doesn't work anymore. – 0x3333 Sep 4 '17 at 22:38

I found the problem.

My mistake, multiple gateway entries, should have only one!

Now it is working.
