Open Stack

Hi!

I am trying to set up Openstack with Kayobe and right now I’m very stuck at VLAN configuration with LACP bonds on my two network nodes.
Last Friday the network even came to a hold when activating Openvswitch because it started a broadcast storm or something in the whole company even though I have 2 VLANs just for this project.

So I am trying to do it like this:

#bond configuration
dummy_net_interface: bond0
dummy_net_bootproto: static
dummy_net_bond_slaves:
  - eno12399np0
  - eno12409np1
dummy_net_bond_mode: 802.3ad
dummy_net_bond_miimon: 100
dummy_net_bond_lacp_rate: fast

#configure mgmt interface
mgmt_net_interface: brmgmt
mgmt_net_bridge_ports:
  - bond0

#external net work interface and bridge configuration
#ext_net_bridge_ports:
ext_net_interface: "brbond{{ ext_net_vlan }}"
ext_net_bridge_ports:
  - "bond0.{{ ext_net_vlan }}"


Part of my networks.yml
…
external_net_names:
  - ext_net
…
ext_net_cidr: 172.31.246.0/24
ext_net_no_ip: true
ext_net_vlan: 705

Last time this worked, when I ran a “kayobe overcloud host configure” (the node had network connection) but then “kayobe overcloud service deploy” killed the network when it started the Openvswitch.

Now (today) this configuration doesn’t even allow to reach the network/(to be)neutron nodes (they lose network connection) when the playbook restarts system-networkd. It already creates OVS PHY bridges and lots of stuff even though I ran “overcloud service destroy” before that. Should it do that at this stage?

Are there any examples to set up a network node with bonds and vlans and external neutron networks out there? Any suggestions?

Thank you 😊

Kind regards
Stefan
