Version-Release number of selected component (if applicable):
RHOS8

How reproducible:
100%

Steps to Reproduce:
1. configure lbaas.
2. dont install haproxy package
3. Try to assign vip to lbaas pool and monitor "/var/log/neutron/lbaas-agent.log"


Actual results:
misleading error if "haproxy" package is missing on lbaas node

Expected results:
Error should point exact issue(missing haproxy package)

i deployed setup with packstack. Further configured lbaas manually. When I was trying to assign vip to lbaas pool, the operation was successful but, the vip was in error state. I observed error mentioned in comment #0. After installing haproxy package issue resolved.

Comment 4 Assaf Muller 2016-06-04 02:15:44 UTC

@Nir, can you please check if haproxy is listed as a dependency of the lbaas v2 agent?

Comment 5 Ihar Hrachyshka 2016-06-08 12:30:46 UTC

I think the assumption is that lbaas can be used with different backends, and hence we should not pull haproxy with deps because f.e. for radware, we don't need it.

I think it's installer's job to install backend pieces for the driver chosen.
