Bug Description

When neutron lbaas agent is not running, all the ‘neutron lb*’ commands display "404 Not Found". This makes the user think that something is wrong with the lbaas agent (when it is not even running!).

Instead, when neutron lbaas agent is not running, an error like “Neutron Load Balancer Agent not running” must be displayed so the user knows that the lbaas agent must be started first.

The ‘ps’ command below shows that the neutron lbaas agent is not running.

$ ps aux | grep lb

I am getting this error even after starting lbaas service.

$ neutron --version

'neutron lb-pool-list' command is returning correct output but 'neutron lbaas-pool-list' is returning 404 error.

$ neutron lbaas-pool-list

I am also facing the same problem as Abhijeet.
Seems that there is some issue in launching of lbaas extension.

it is not a client side issue.
I will change the affected project to neutron and add tag 'lbaas'.

affects:

python-neutronclient → neutron

lb-pool-list is for Neutron LBaaS v1 API and lbaas-pool-list is for LBaaS v2 API.
In your environment, LBaaS v1 extension is enabled and LBaaS v2 exntension is disabled.
Returning 404 response to non-loaded extensions is the design decision in Neutron at now.
