@Cheryl

That issue appears to unrelated. I just redeployed openstack and it did not happen again.

Title:
  maas bridge script handles VLAN NICs incorrectly

Status in juju-core:
  Fix Committed
Status in juju-core 1.25 series:
  In Progress

Bug description:
  In Juju 1.25 and master (soon to be 2.0-alpha1), but specifically
  *not* in the maas-spaces branch, the add-juju-bridge.py script we use
  on the MAAS provider does not render the changes to
  /etc/network/interfaces correctly when multiple VLAN virtual NICs are
  configured on top of one or more physical NICs.

  Here's an example of /e/n/i on a KVM node deployed with MAAS 1.9rc4
  through juju, before the bridge script changes it:

  auto eth0
  iface eth0 inet static
      gateway 10.20.19.2
      address 10.20.19.103/24
      mtu 1500

  auto eth0.100
  iface eth0.100 inet static
      address 10.100.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 100

  auto eth0.250
  iface eth0.250 inet static
      address 10.250.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 250

  auto eth0.50
  iface eth0.50 inet static
      address 10.50.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 50

  dns-nameservers 10.10.19.2
  dns-search maas-19

  And here is how it looks like after the script:

  iface eth0 inet manual

  auto juju-br0
  iface juju-br0 inet static
      bridge_ports eth0
      gateway 10.20.19.2
      address 10.20.19.103/24
      mtu 1500

  auto juju-br0.100
  iface juju-br0.100 inet static
      address 10.100.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 100

  auto juju-br0.250
  iface juju-br0.250 inet static
      address 10.250.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 250

  auto juju-br0.50
  iface juju-br0.50 inet static
      address 10.50.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 50

  dns-nameservers 10.10.19.2
  dns-search maas-19

  This causes errors by ifup at boot when the script is trying to
  activate the modified /e/n/i (e.g. cannot add juju-br0.100 using eth0
  as raw device, as eth0.100 already exists).

  In comparison, here is the same /e/n/i after it got modified by the
  improved bridge script in the maas-spaces feature branch:

  iface eth0 inet manual

  auto br-eth0
  iface br-eth0 inet static
      gateway 10.20.19.2
      address 10.20.19.103/24
      mtu 1500
      bridge_ports eth0

  iface eth0.100 inet manual
      address 10.100.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 100

  auto br-eth0.100
  iface br-eth0.100 inet static
      address 10.100.19.103/24
      mtu 1500
      bridge_ports eth0.100

  iface eth0.250 inet manual
      address 10.250.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 250

  auto br-eth0.250
  iface br-eth0.250 inet static
      address 10.250.19.103/24
      mtu 1500
      bridge_ports eth0.250

  iface eth0.50 inet manual
      address 10.50.19.103/24
      vlan-raw-device eth0
      mtu 1500
      vlan_id 50

  auto br-eth0.50
  iface br-eth0.50 inet static
      address 10.50.19.103/24
      mtu 1500
      bridge_ports eth0.50

  dns-nameservers 10.10.19.2
  dns-search maas-19

  The new script has an issue with multiple "dns-*" options, but I'll
  file a separate bug for it.
