nrado1 | Hi, today I deployed LbaaS with Octavia driver, but the lbaas agents are not listed within the neutron agents and I'm getting this error in the lbaas-logs: https://gist.github.com/anonymous/553d786dc5284d70763157f9efd697e9. | 13:47 |
nrado1 | Is this a known issue? I deployed OpenStack with Kolla (Pike version + Ubuntu as the operating system of the containers). I've restarted neutron-server, rabbitmq and lbaas-agents. But the error is still there. | 13:47 |
nrado1 | Neutron LBaaS Version: 11.0.0.0rc2.dev3 | 13:47 |
xgerman_ | you don’t need LBaaS agents with Octavia | 13:48 |
nmagnezi | nrado1, Octavia does not require that agent | 13:49 |
nmagnezi | oh, sorry xgerman_ didn't see you answer it. | 13:49 |
xgerman_ | ;-) | 13:49 |
nrado1 | ah ok, good to know :D But i still use the neutron lbaas-… commands for creating them? | 13:49 |
*** yamamoto has joined #openstack-lbaas | 13:50 | |
*** yamamoto_ has joined #openstack-lbaas | 13:50 | |
nmagnezi | nrado1, there's a client called python-octaviaclient we may use. If you use Octavia as it's own keystone endpoint that would be your way to go | 13:52 |
nrado1 | great, thank you very much! I'll give it a try | 13:53 |

nrado | Hi, when I execute openstack loadbalancer list, I'm getting this: https://gist.github.com/neki06/f6b047db31e075eafba6234c0400fb33 | 16:54 |
nrado | pip show python-octaviaclient | 16:55 |
nrado | Name: python-octaviaclient | 16:55 |
nrado | Version: 1.1.0 | 16:55 |
nrado | openstack --version | 16:55 |
nrado | openstack 3.12.0 | 16:55 |
nrado | Did I miss something? | 16:55 |
*** chlong has quit IRC | 16:58 | |
johnsom | That is interesting. Never seen that before. | 17:00 |
johnsom | nrado can you run "openstack --debug loadbalancer list" and gist the output? | 17:00 |
johnsom | I am guessing it's sending something back that is not in the right format | 17:01 |
nrado | yes, give me a second | 17:01 |
nrado | https://gist.github.com/neki06/e9da017f4b4dd8299e3f3e173e2d9f50 | 17:02 |
johnsom | Wow, ok, I guess we have a bug. I wonder what caused that.... | 17:05 |
johnsom | Let me try something local. | 17:05 |
johnsom | Hmmm, odd, I just tried that local and it worked. | 17:06 |
johnsom | stack@devstackpy27-2:~/devstack$ openstack loadbalancer list | 17:06 |
johnsom | stack@devstackpy27-2:~/devstack$ | 17:06 |
johnsom | Ok, so my debug output does not look like yours. | 17:07 |
johnsom | https://www.irccloud.com/pastebin/KXOV1BSo/ | 17:07 |
nrado | hm, ok. Maybe I did something wrong, but I don't know what | 17:09 |
johnsom | What release of Octavia did you install? | 17:09 |
*** harlowja has joined #openstack-lbaas | 17:10 | |
nrado | octavia-api --version | 17:10 |
nrado | %prog 0.10.0 | 17:10 |
nrado | May I ask you something. I always used lbaas with the default haproxy driver | 17:11 |
johnsom | Ah, so you have Ocata | 17:11 |
nrado | Yeah, sorry forgot to mention that! | 17:11 |
johnsom | That is before the Octavia API was released in Pike. OpenStack client only works with Pike or newer. | 17:11 |
johnsom | With Ocata you have to keep using the neutron-lbaas driver and "neutron" client | 17:12 |
nrado | ah ok | 17:12 |
nrado | but may I ask you something | 17:12 |
johnsom | Sure | 17:13 |
nrado | someone told me that I don't need lbaas-agent anymore, but why do I still have to edit neutron_lbaas.conf to use Octavia driver? | 17:14 |
*** chlong has joined #openstack-lbaas | 17:15 | |
johnsom | With versions older than Pike, Octavia is only available as a driver to neutron lbaas (There are many driver options for neutron-lbaas: Octavia (reference driver), F5, Radware, VMware, etc.). Neutron-lbaas is a neutron extension. | 17:15 |
johnsom | Octavia does not use neutron agents, but you still need to configure the neutron-lbaas extension to make the Octavia driver available. | 17:16 |
johnsom | In Pike we made it so you no longer need neutron-lbaas, you can go directly to octavia. | 17:17 |
johnsom | This diagram in our docs shows the Ocata setup: https://docs.openstack.org/octavia/latest/reference/introduction.html#a-10-000-foot-overview-of-octavia-components | 17:19 |
*** eezhova has joined #openstack-lbaas | 17:21 | |
nrado | Ok, I got this. I'm asking this because I'm deploying with Kolla and trying to understand the differences between default haprxy and octavia. So in my case I still need lbaas containers, right? | 17:21 |
nrado | It's confusing for me | 17:21 |
johnsom | The haproxy namespace driver should not be default. It is very limited and not much support. | 17:22 |
nrado | I know, that's why I want to change the driver | 17:22 |
johnsom | Hmm, I have not used kolla, so not sure. I can see if I read up | 17:22 |
nrado | But regardless of wheter I use Pike or Ocata I don't need the lbaas agent anymore, is this right? | 17:24 |
johnsom | Correct | 17:24 |
johnsom | Octavia never used a neutron agent | 17:24 |
nrado | ok, thank you :) | 17:25 |
johnsom | NP | 17:26 |

rm_work | kong: great, thank you | 19:01 |
rm_work | kong: i will try to do this soon, although this week I have a big demo to prepare for today/tomorrow, so I may not get to it T_T | 19:01 |
rm_work | though, I will try this morning | 19:01 |
rm_work | kong: the legacy-requirements thing is failing because of zuul issues I think, or at least it's a global thing for octavia and is not a problem with your patch, so for now you can ignore it | 19:02 |
rm_work | johnsom: who do we still know that is very experienced with haproxy? | 19:07 |
johnsom | Us for the most part. Baptiste isn’t there anymore | 19:08 |
rm_work | johnsom: i am somewhat led to believe it is related to the haproxy side, as i noticed that configuring only a single member gives me ~25k/s (about what I'd expect compared to 55k/s direct to backend) | 19:08 |
rm_work | but adding a second member to the pool drops it to ~16k and then third or more member settles at ~10k | 19:09 |
*** chlong_ has joined #openstack-lbaas | 19:09 | |
rm_work | it's just round-robin, i wouldn't expect adding more members to kill performance that much | 19:09 |
rm_work | but i guess it does somehow | 19:09 |
*** belharar has joined #openstack-lbaas | 19:13 | |
johnsom | Yeah, that is strange behavior we need to figure out. Not normal by any means | 19:13 |

nmagnezi | just spinning up another devstack for those dashboard nodes | 20:34 |
nmagnezi | johnsom, btw re-ran https://review.openstack.org/#/c/503638/ and for some very strange reason I still get a strange error from nova when I try to spawn instances (fresh devstack node) | 20:35 |
nmagnezi | still not sure why | 20:35 |
johnsom | nmagnezi What is the error? | 20:35 |
nmagnezi | johnsom, something about that a <hostname> is not defined as a nova cell | 20:37 |
kong | thanks, rm_work | 20:39 |
kong | and morning, btw | 20:39 |
rm_work | johnsom: ok so you think... haproxy in openstack just ... won't go over 10k | 20:39 |
rm_work | ? | 20:39 |
johnsom | No, I think it is something else. Like I said, I get the same inside and outside | 20:40 |
rm_work | whelp, k | 20:45 |
rm_work | this is ... what env? | 20:46 |
rm_work | NOT devstack? | 20:46 |
rm_work | or still in your devstack VM | 20:46 |
johnsom | Just vmware instances | 20:48 |
rm_work | hmm | 20:48 |
rm_work | ok i can repro in staging that my numbers from from ~20k to ~10k when i go from one member to two | 20:50 |
