mwhahaha | hrm looks like the neutron beaker tests are flakey | 13:46 |
mwhahaha | specifically the ovs check, http://logs.openstack.org/35/645735/1/gate/puppet-openstack-beaker-centos-7/569cb11/job-output.txt.gz#_2019-03-29_07_32_12_297021 | 13:46 |

beagles | mwhahaha: looks like the thing to confirm is whether br-tun is still expected or not if it isn't required to connect nodes - I'd kind of imagine it would be | 15:10 |
beagles | mwhahaha: chatting with some of the neutron folks for insights | 15:10 |
mwhahaha | yea it looks like it's checking for the creation of it or something | 15:10 |
mwhahaha | it's partially succeeding | 15:10 |
beagles | ue[ | 15:11 |
beagles | err.. yep | 15:11 |
mwhahaha | so it'll pass check then fails in gate, it's been happening for a bit | 15:11 |
beagles | ah okay .. pretty weird | 15:13 |
mwhahaha | see https://review.openstack.org/#/c/638149/ | 15:14 |

*** ykarel has quit IRC | 15:40 | |
beagles | mwhahaha: is there a time interval after the services are brought that the beaker tests wait for before running the accepetance tests? | 15:49 |
mwhahaha | not completely sure, this isn't a new test | 15:49 |
beagles | mwhahaha: seems like either they sometimes run before the neutron server has a chance to sync with the ovs agent - of course it could also be an issue where the agent and service simply fail to sync too | 15:50 |
mwhahaha | i think puppet should fully run | 15:50 |
mwhahaha | and then it tests | 15:50 |
mwhahaha | this test is 4 years old | 15:51 |
mwhahaha | so it's unlikely a problem with our testing :D | 15:51 |
beagles | yeah - I agree | 15:51 |
*** trown is now known as trown|lunch | 15:58 | |
beagles | mwhahaha: around when did this start happening - like in the last week or longer? | 16:05 |
openstackgerrit | Merged openstack/puppet-monasca stable/stein: Switch to stable/stein https://review.openstack.org/647347 | 16:05 |
mwhahaha | beagles: not sure we haven't really merged a bunch of stuff. i think it got worse over the last week or so | 16:10 |
mwhahaha | so looks like longer | 16:11 |
mwhahaha | https://review.openstack.org/#/c/638149/ had a failure on mar 4 | 16:11 |
mwhahaha | i don't see one earlier, so probably end of Feb early march (depending on promotions) | 16:12 |
beagles | mwhahaha: k some neutron devs pointed out a recent change that plays around with sync on startup etc but that seems to do with scale | 16:15 |
mwhahaha | openstack-neutron-14.0.0-0.20190227064311.376fa8a.el7.noarchwas ok | 16:15 |
mwhahaha | openstack-neutron-14.0.0-0.20190301122617.7fbba81.el7.noarch started failing | 16:16 |
beagles | ah good info | 16:16 |
mwhahaha | https://review.openstack.org/#/c/636719/ | 16:17 |
mwhahaha | maybe not but that merged around then | 16:17 |
mwhahaha | there's a few ovs things added around then | 16:18 |
mwhahaha | https://review.openstack.org/#/c/626545/ | 16:18 |
mwhahaha | oh nm that was pike | 16:18 |
* mwhahaha adjusts filter | 16:18 | |
mwhahaha | oh i wonder, http://logs.openstack.org/49/638149/3/gate/puppet-openstack-beaker-centos-7/43dd568/logs/neutron/openvswitch-agent.txt.gz#_2019-03-05_03_24_35_884 | 16:21 |
mwhahaha | heh looks like a "passing" job had the rpc_response_max_timeout fail in it http://logs.openstack.org/49/638149/3/check/puppet-openstack-beaker-centos-7/7ecfe9e/logs/neutron/openvswitch-agent.txt.gz#_2019-02-28_04_08_51_620 | 16:21 |
mwhahaha | i bet it's the exponential backoff in the agent | 16:22 |
mwhahaha | cause it goes 7,20,240 | 16:22 |
beagles | yeah, the failed one has two such things http://logs.openstack.org/35/645735/1/gate/puppet-openstack-beaker-centos-7/569cb11/logs/neutron/openvswitch-agent.txt.gz | 16:22 |
mwhahaha | and we run the beaker tests somewhere after the 20 | 16:22 |
mwhahaha | the passing one just waited 12 seconds | 16:23 |
mwhahaha | http://logs.openstack.org/49/638149/3/check/puppet-openstack-beaker-centos-7/7ecfe9e/logs/neutron/openvswitch-agent.txt.gz#_2019-02-28_04_08_51_593 | 16:23 |
*** tosky has quit IRC | 16:23 | |
mwhahaha | so yea it seems tobe the rpc timeout | 16:33 |
mwhahaha | http://logs.openstack.org/35/645735/1/check/puppet-openstack-beaker-centos-7/b21d4e0/logs/neutron/openvswitch-agent.txt.gz#_2019-03-22_18_03_51_774 | 16:33 |
mwhahaha | that's a success, it waited 29 sec | 16:33 |
mwhahaha | so i wonder what we need to tun or start in a different order | 16:34 |
beagles | mmmm I wonder what our actual start order is now... | 16:34 |
mwhahaha | all at the same time | 16:35 |
mwhahaha | http://logs.openstack.org/35/645735/1/check/puppet-openstack-beaker-centos-7/b21d4e0/job-output.txt.gz#_2019-03-22_18_02_45_590877 | 16:35 |
*** pgaxatte has quit IRC | 16:36 | |
mwhahaha | so it's likely resource contention and when ovs checks neutron isn't up yet, so it goes expentional backoff and if it does a shorter recheck (7,20) then it doesn't suceed before it goes to teh long one (240) | 16:37 |
mwhahaha | i guess we could bump rpc_response_timeout in the beaker tests but that's just covering this up | 16:42 |
beagles | agreed | 16:42 |
mwhahaha | so it's an issue witht he max_rpc_timeout | 16:51 |
mwhahaha | it's used in the backoff | 16:51 |
mwhahaha | beagles: it's because of https://review.openstack.org/#/c/623401/ | 16:52 |
mwhahaha | we didn't previously exponential based on the max timeout | 16:52 |
mwhahaha | so it was likely the addition of the max timeout to the ovs bits that started to make this show up | 16:53 |
mwhahaha | so we likely need to drop rpc_response_max_timeout from the default of 600 | 16:53 |
mwhahaha | for most people this is likely fine but the beaker tests this doesn't work | 16:53 |
beagles | ack | 16:54 |
mwhahaha | and we don't expose a way to configure rpc_response_max_timeout | 16:54 |
mwhahaha | fantastic | 16:54 |

beagles | while turning this config knob might mitigate things, the introduction of the config shouldn't have made things worse - or am I missing something? like did backoff not work the same before? | 16:59 |
mwhahaha | it didn't work the same before | 16:59 |
mwhahaha | i think it's a combination of things | 17:00 |
mwhahaha | let me get this rpc config in and then i'll try and go back in time | 17:01 |

mwhahaha | alright lets try those | 17:11 |
beagles | mwhahaha: added comment to the puppet-neutron patch - rodolfo added it to the ovs agent as well https://review.openstack.org/#/c/636719/ | 17:15 |
*** owalsh has quit IRC | 17:15 | |
beagles | so maybe we want to configure that one as well? | 17:16 |
mwhahaha | where is that? that one seems to be the server config settings | 17:16 |
*** owalsh has joined #puppet-openstack | 17:17 | |
mwhahaha | for now we can just kill off br-tun checks until we get this sorted | 17:17 |
beagles | mwhahaha: ack | 17:17 |
beagles | with respect to that patch it basically splits the rpc_response_max_timeout into a separate group and then looks like it adds it as a base agent opts or something like that | 17:20 |
mwhahaha | yea it's not super clear | 17:22 |
mwhahaha | i'm not even sure it'll fix it | 17:22 |
mwhahaha | other than dropping the max response timeout to 60 to ensure it never exceeds that | 17:22 |
beagles | ack | 17:22 |
mwhahaha | we'll see | 17:22 |
mwhahaha | there's really not a good way to handle this because for most folks it shouldn't matter if the agent comes up instantly or it takes a minute | 17:23 |
mwhahaha | just in ci it's annoying | 17:23 |
