I've been trying to get the v2 load balancer setup in Openstack using the official documentation(https://docs.openstack.org/ocata/networking-guide/config-lbaas.html).

Following the steps I get stuck at step 4:

Step 1: Edit this file /etc/neutron/neutron.conf

Step 2: Edit this file /etc/neutron/neutron_lbaas.conf ( doesn't exist for me but I created it anyway).
Step 3: Edit this file /etc/neutron/lbaas_agent.ini ( doesn't exist for me but I created it anyway).
Step 4: Run this command (neutron-db-manage --subproject neutron-lbaas upgrade head). After running it Neutron says it doesn't know what neutron-lbaas is.

Output:

[root@controller ~]# neutron-db-manage --subproject neutron-lbaas upgrade head argument --subproject: Invalid String(choices=['neutron']) value: neutron-lbaas

I get this same output from an all-in-one RDO installation and a manual 4 node installation of Ocata.

What am I doing wrong?
