Re: [openstack-dev] [lbaas]HA for lbaas v2 agent
As Assaf mentioned, namespace and octavia are two different lbaas drivers. But within those: - The lbaas plugin will schedule lbaas VIPs from all available lbaas-agents (I think it’s random.) No, you can’t move them later, or override the scheduler. - The lbaas agent is used by the octavia driver. Octavia is its own REST endpoint, and the lbaas driver for it just makes synchronous REST calls.

The LBaaS v2 API has multiple implementations. One of which is based off haproxy and namespaces, known as the agent based implementation. Do you have neutron-lbaas-agent running on your network nodes? The second implementation is called Octavia and is based off service VMs instead of agents and namespaces. Octavia calls out to Nova to create VMs and inside those VMs is an agent that talks back to Octavia, and that creates an haproxy instance to perform the actual loadbalancing. The answer to both of your questions depends on which of these two implementations you're going with. There's a bunch of summit sessions about Octavia you can look in to. > > Thanks > Akshay > > On Thu, Jun 23, 2016 at 1:00 AM, Assaf Muller wrote: >> >> On Wed, Jun 22, 2016 at 3:17 PM, Akshay Kumar Sanghai >> wrote: >> > Hi, >> > I have a multinode openstack installation (3 controller, 3 network >> > nodes, >> > and some compute nodes). >> > Like l3 agent, is high availability feature available for the lbaas v2 >> > agent? >> >> It is not.

Re: [openstack-dev] [lbaas]HA for lbaas v2 agent
Thanks Assaf. I have few questions for lbaas: - if i run agents on multiple nodes, will the request be ditrsibuted by neutron-server? - Does neutron lbaas agent forward the request to octavia-api or the neutron-server?

It is not.

[openstack-dev] [lbaas]HA for lbaas v2 agent
Hi, I have a multinode openstack installation (3 controller, 3 network nodes, and some compute nodes). Like l3 agent, is high availability feature available for the lbaas v2 agent?
