| johnsom | greghaynes Thanks for poking at the elements again. I think the issue with the haproxy merged element is it is installing the non-backports version of haproxy which we don't support. | 00:15 |

| Chenhao | Hi guys, I found that in the amphora VM there is an "amphora-haproxy" namespace. But that namespace disappeared if I reboot the amphora VM. | 19:01 |
| Chenhao | Anyone know when this namespace was created? | 19:02 |
| bana_k | Chenhao https://github.com/openstack/octavia/blob/master/octavia/amphorae/backends/agent/api_server/plug.py#L127 | 19:03 |
| *** amotoki has quit IRC | 19:04 | |
| Chenhao | Oh~ Thanks very much bana_k :) | 19:07 |
| rm_work | Chenhao: I think there should have been code in place to make that work properly | 19:12 |
| rm_work | Chenhao: but if reboots are causing problems, this is possibly a known issue | 19:12 |

| *** yamamoto has joined #openstack-lbaas | 19:18 | |
| Chenhao | Hi rm_work, based on the code point by bana_k, I assume the namespace should be created when plug_vip() was called. Seems like there is a rest api call for plug_vip https://github.com/openstack/octavia/blob/master/octavia/amphorae/backends/agent/api_server/server.py#L111 | 19:21 |
| rm_work | yes, but on a reboot it should retain that configuration | 19:22 |
| *** yamamoto has quit IRC | 19:22 | |
| Chenhao | In side the amphora vm, I only saw the api was called once 2016-08-19 18:52:49.923 1374 INFO werkzeug [-] 192.168.254.3 - - [19/Aug/2016 18:52:49] "POST /0.5/plug/vip/10.0.0.48 HTTP/1.1" 202 -" | 19:22 |
| bana_k | Chenhao and there is still an ongoing discussion about do we need to reboot a LB VM. | 19:23 |
| Chenhao | yeah~ That could be the situation :) | 19:23 |
| rm_work | Chenhao: yes, it would only be called once by the controller at create time | 19:24 |
| rm_work | on reboot, it would not be called again -- but it SHOULD retain the existing network configuration -- if something else is happening, it might be something specific to your environment? do you have a network agent that could be rewriting the configurations on boot? | 19:24 |
| rm_work | at rackspace we ran into that problem somewhat | 19:24 |
| Chenhao | I am trying to debugging Octavia with DVR. And try to see whether I can find the root cause of the problem why Octavia doesn't work in an DVR environment | 19:25 |
| *** rudrajit has quit IRC | 19:26 | |

| *** rudrajit has quit IRC | 19:31 | |
| *** cody-somerville has quit IRC | 19:31 | |
| bana_k | Chenhao I think it was a prob with allowed address pairs in DVR | 19:31 |

| Chenhao | I saw that ticket that complaining about DVR doesn't support allow ip pairs. But when I test this blog http://blog.aaronorosen.com/?p=320, I can actually make the vrrp settings working for the fix ip address. | 20:08 |
| *** rudrajit has quit IRC | 20:10 | |
| *** numans has quit IRC | 20:10 | |
| Chenhao | So it makes feel like DVR can at least support some part of allow ip pairs. I just trying to see whether I can at least make the amphora working without floating ips. | 20:11 |
| Chenhao | Actually the problem I saw in my environment is "upstart/network-interface-eth1.log:Error getting hardware address for "eth1": No such device" | 20:13 |
| Chenhao | In devstack I saw "eth1.cfg" exist in '/etc/netns/amphora-haproxy/network/interfaces.d" in the amphora VM, but somehow in my DVR environment I saw "eth1.cfg" exist in "/etc/network/interfaces.d" | 20:18 |
| Chenhao | This is a little weird, because eth1 should be an interface inside the amphora-haproxy namespace, its configuration should under the namespace folder which is "etc/netns/amphora-haproxy/network/interfaces.d" just like devstack did | 20:22 |

| Chenhao | Great~ Thanks very much johnsom :) | 21:17 |
| johnsom | chenhao I'm am pretty sure that that blog post about allowed address pairs is broken with DVR. Putting a floating IP in front of the vip IP address will fail if DVR is enabled. | 21:19 |
| johnsom | Octavia should work on DVR networks, just DVR has a bug with floating IPS | 21:20 |
| *** ducttape_ has quit IRC | 21:21 | |
| Chenhao | johnsom I haven't test the floating ip with that vrrp settings. What my test did is just verify the fix vip and mac address could be moved using that vrrp settings in an DVR environment. Also looking at some possible solutions to make DVR working with vrrp floating ips. | 21:23 |
| Chenhao | Seems like we need to fix the vrrp floating ip for DVR first. | 21:24 |
| johnsom | Yeah, I think just moving the IP back and forth, kind of works with DVR. | 21:24 |
| *** bana_k has quit IRC | 21:28 | |
| Chenhao | For now I think the only mechanism I could come up is like launch two normal VMs which don't use VRRP and try to set an aodh alarm monitoring the amphora VMs if the first amphora VMs dead move the floating ip to the second VM. This could be done automatically by using some heat template. | 21:29 |
| johnsom | Yeah, but that is horribly slow. With VRRP and DVR disabled we failover in about a second. | 21:30 |
| Chenhao | I agree. | 21:30 |
| Chenhao | Anyway it seems like a long way to go, base on the architecture of DVR it won't be an easy fix. | 21:32 |
| johnsom | My off the head answer was (back when were were talking about this) DVR should light up the flip on all instances that have the allowed address pair. It should then have something watching for the GARPs that updates DVR's static arp table. Much like normal switches do | 21:32 |
| johnsom | There are probably reasons that won't work as I haven't done a deep dive on the DVR implementation in a long time. | 21:34 |

| Chenhao | I need to digging more before I can say whether it will work or not... | 21:35 |
| Chenhao | Another question, anyone notice we have a race condition here? https://github.com/openstack/octavia/blob/master/octavia/amphorae/backends/agent/api_server/plug.py#L133 | 21:35 |
| johnsom | Do you mean if the interface has already been moved? | 21:36 |
| Chenhao | what will happen if the link is not ready when we try to make this call? | 21:37 |
| Chenhao | I mean the interface hasn't been created | 21:37 |
| johnsom | But it is created in a previous step. This is the "post VIP plug" method that is called after it has been created | 21:38 |
| Chenhao | Not sure whether it is only in my environment, I saw this error "./kern.log:Aug 19 18:52:45 amphora-e11d8b3b-a3c6-421d-9936-d7cba58073f6 kernel: [ 4.987287] IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready" | 21:39 |
| Chenhao | and eth1 was not moved to the amphora-haproxy namespace. | 21:39 |
| johnsom | Yeah, that is a bogus error. It's there because I don't delete the eth1.cfg out of the global network namespace | 21:39 |
| Chenhao | hmm... Can you point me the place where the interface was created? | 21:41 |
| johnsom | Chenhao I would test with the failover patch I sent you. There was a numbering issue during failovers that could cause the eth1 to not move correctly, but otherwise I haven't seen a problem there. I have recently run a lot of tests for the failover patch. | 21:41 |
| Chenhao | Sounds cool~ :) | 21:42 |
| johnsom | This task: https://github.com/openstack/octavia/blob/master/octavia/controller/worker/tasks/network_tasks.py#L263 | 21:42 |
| Chenhao | Thanks very much johnsom, let me try to learn that first :) | 21:43 |
| johnsom | Once that task completes nova will have attached the network interface and the kernel will see the hot-plug. eth1 with be present in the kernel at that point. Not configured, but present. | 21:43 |
