tpatil | #link : https://review.opendev.org/#/c/675561/ | 08:16 |
dkushwaha | tpatil, i will review it. | 08:18 |
dkushwaha | It goes tough on tosca-parser side as it not under Tacker repo | 08:18 |
dkushwaha | I will ping tosca-parser guys if they can be available | 08:18 |
tpatil | I can understand. Niraj has already sent an mail to Bob asking to review the tosca-parser patch | 08:18 |
tpatil | We will try to follow-up with Bob again | 08:19 |
dkushwaha | tpatil, hmm, i also pinged him for some other patches, but seems no response | 08:19 |
dkushwaha | tpatil, i think doc is missing still missing in package support patch. once client patch available could you please give some highlight, that how to test | 08:21 |
tpatil | Sure, I will add the doc to explain how to setup and test vnf packages | 08:22 |

hyunsikyang | And about user guide, I will add my user guide to kubernetes VIM user guide. | 08:32 |
dkushwaha | hyunsikyang, yea, I think it is not a good idea to have different doc for multi-interface, so it can be merged in existing one | 08:33 |

dkushwaha | hyunsikyang, https://review.opendev.org/#/c/582487/ https://review.opendev.org/#/c/662171/ | 08:42 |

*** macz has joined #openstack-meeting | 16:07 | |
slaweq | mlavalle: so, based on Your comment, it looks that it could be introduced by https://review.opendev.org/#/c/597567, right? | 16:07 |
slaweq | as it is some race condition in case when router is updated | 16:08 |
mlavalle | well, not necessarilly that patch | 16:08 |
mlavalle | there are other 2 patches that have touched the "ralted routers" code later | 16:08 |
mlavalle | which I also mention in the bug | 16:08 |
mlavalle | the naive solution would be for each test case in the test_magrations script to create its router in separate nets / subnets | 16:09 |
mlavalle | that would fix our tests | 16:09 |
mlavalle | but this is a real bug IMO | 16:10 |
mlavalle | which we need to fix | 16:10 |
mlavalle | right? | 16:10 |
slaweq | so different routers from those tests are using same networks/subnets now? | 16:10 |
bcafarel | and backport :) | 16:10 |
mlavalle | I am assuming that | 16:11 |
slaweq | isn't it that there is one migration "per test"? | 16:11 |
slaweq | and then new network/subnet created per each test | 16:11 |
mlavalle | well, if that is the case, the problem is even worst | 16:11 |
mlavalle | why would the router under migration have related routers? | 16:12 |
*** gyee has joined #openstack-meeting | 16:12 | |
slaweq | but here: https://github.com/openstack/neutron-tempest-plugin/blob/master/neutron_tempest_plugin/scenario/test_migration.py#L124 it looks like every test has got own network and subnet | 16:13 |
slaweq | IMO it's created here: https://github.com/openstack/neutron-tempest-plugin/blob/master/neutron_tempest_plugin/scenario/test_migration.py#L129 | 16:13 |
slaweq | this method is defined here https://github.com/openstack/neutron-tempest-plugin/blob/d11f4ec31ab1cf7965671817f2733c362765ebb1/neutron_tempest_plugin/scenario/base.py#L173 | 16:14 |
mlavalle | see my comment just before yours please ^^^^ | 16:14 |
mlavalle | we agree | 16:14 |
slaweq | yes, so it seems that it is "even worst" :) | 16:15 |
mlavalle | I have a question that I want to confirm.... | 16:16 |
slaweq | shoot | 16:16 |
mlavalle | the related routers ids are sent to the L3 agent in the router update rpc message, right? | 16:17 |
slaweq | yes (IIRC) | 16:18 |
slaweq | but delete router should also be sent in such case to controller, no? | 16:18 |
mlavalle | in other words, this line https://github.com/openstack/neutron/blob/master/neutron/agent/l3/agent.py#L720 | 16:18 |
mlavalle | returns a non empty list, correct | 16:18 |
mlavalle | in the case of a router migration, what is sent from the server to the agent is a router update | 16:19 |
mlavalle | because we are not deleting the router | 16:19 |
mlavalle | we are just setting admin_state_up to false | 16:20 |
mlavalle | let's move on | 16:20 |
mlavalle | I can test that locally | 16:20 |
slaweq | but, according to Your paste: | 16:20 |
slaweq | http://paste.openstack.org/show/769795/ | 16:21 |
slaweq | router 2cd0c0f0-75ab-444c-afe1-be7c6a1a7702 was deleted on compute | 16:21 |
slaweq | and was only updated on controller | 16:21 |
slaweq | why? | 16:21 |
mlavalle | yes, but that is the result of processing an update | 16:21 |
mlavalle | an update message | 16:21 |
mlavalle | not a delete message | 16:21 |
slaweq | true | 16:22 |
mlavalle | that I am 100% sure | 16:22 |
mlavalle | the difference is that when the update message contains "related routers" updates | 16:23 |
mlavalle | is is processed in a different manner | 16:23 |
mlavalle | and therefore the router is not deleted locally in the agent | 16:23 |
mlavalle | delete the router locally means removing the network space form that agent, even though the router still exists | 16:24 |
slaweq | but what are related routers in such case? | 16:24 |
mlavalle | that is excatly the conundrum :-) | 16:24 |
slaweq | :) | 16:24 |
mlavalle | why does the router under migration has related routers? | 16:25 |
slaweq | maybe You should send patch with some additional debug logging to get that info later | 16:25 |
*** ricolin_ has quit IRC | 16:25 | |
mlavalle | that is exactly the plan | 16:25 |
slaweq | ok | 16:25 |
slaweq | #action mlavalle to continue investigating router migrations issue | 16:26 |
slaweq | fine ^^? | 16:26 |
mlavalle | yeap | 16:26 |
slaweq | ok | 16:26 |
slaweq | thx a lot mlavalle for working on this | 16:27 |
slaweq | let's move on | 16:27 |
mlavalle | :-) | 16:27 |
*** kopecmartin is now known as kopecmartin|off | 16:27 | |

slaweq | njohnston will get the new location for periodic jobs logs | 16:27 |
njohnston | I did that at the end of the last meeting | 16:27 |
njohnston | and then contacted the glance folks for their broken job that was affecting all postgresql | 16:27 |
slaweq | njohnston: do You have link to those logs then? | 16:28 |
slaweq | just to add it to CI meeting agenda for the future :) | 16:28 |
njohnston | you can look here: http://zuul.openstack.org/builds?pipeline=periodic-stable&project=openstack%2Fneutron | 16:29 |

slaweq | and thx a lot for taking care of broken postgresql job | 16:31 |
slaweq | ok, let's move on to the next topic | 16:32 |
slaweq | #topic Stadium projects | 16:32 |
*** openstack changes topic to "Stadium projects (Meeting topic: neutron_ci)" | 16:32 | |
slaweq | first | 16:32 |
slaweq | Python 3 migration | 16:32 |
slaweq | Stadium projects etherpad: https://etherpad.openstack.org/p/neutron_stadium_python3_status | 16:32 |
slaweq | I saw today that we are in pretty good shape with networking-odl now thank to lajoskatona | 16:32 |
slaweq | and we made some progress with networking-bagpipe | 16:32 |
slaweq | so only "not touched" yet is networking-midonet | 16:33 |
*** ociuhandu has quit IRC | 16:33 | |
slaweq | anything else You want to add regarding to python 3 migration? | 16:33 |
njohnston | No, I think that covers it, thanks! | 16:33 |
slaweq | thx | 16:34 |
slaweq | so next is | 16:34 |
*** ociuhandu_ has quit IRC | 16:35 | |
slaweq | tempest-plugins migration | 16:35 |
slaweq | Etherpad: https://etherpad.openstack.org/p/neutron_stadium_move_to_tempest_plugin_repo | 16:35 |
slaweq | any updates on this one? | 16:35 |
*** dtrainor has joined #openstack-meeting | 16:36 | |
njohnston | I don't have any; I don't see tidwellr and mlavalle is AFK, they are who I would look at for updates. | 16:36 |
slaweq | njohnston: right | 16:36 |
slaweq | so lets move on then | 16:36 |

slaweq | #link http://grafana.openstack.org/dashboard/db/neutron-failure-rate | 16:36 |
slaweq | I see that neutron-functional-python27 in gate queue was failing quite often last week | 16:38 |
slaweq | was there any known problem with it? | 16:38 |
slaweq | do You know? | 16:38 |
ralonsoh | no sorry | 16:38 |
slaweq | ok, maybe it wasn't any big problem as there was only few runs of this job then | 16:39 |
slaweq | so it wasn't relatively many failures | 16:39 |
* mlavalle is back | 16:39 | |
*** yamamoto has joined #openstack-meeting | 16:39 | |
slaweq | from other things I see that neutron-tempest-plugin-scenario-openvswitch in check queue is failing quite often | 16:40 |
slaweq | any volunteer to check this job more deeply? | 16:40 |
slaweq | if no, I will assign it to myself for this week | 16:41 |
ralonsoh | I can take a look, but I don't know when | 16:41 |
ralonsoh | I have a very busy agenda now | 16:41 |
slaweq | ralonsoh: thx | 16:42 |
slaweq | but if You are busy, I can take a look into this | 16:42 |
slaweq | so I will assign it to myself | 16:42 |
slaweq | to not overload You :) | 16:42 |
slaweq | ok? | 16:42 |
ralonsoh | thanks! | 16:42 |
slaweq | #action slaweq to check reasons of failures of neutron-tempest-plugin-scenario-openvswitch job | 16:43 |
slaweq | from other things which I noticed from grafana, neutron-functional-with-uwsgi high failure rate but it's non voting so no big problem (yet) | 16:43 |
*** yamamoto has quit IRC | 16:43 | |
slaweq | I hope we will be able to focus more on stabilizing uwsgi jobs in next cycle :) | 16:44 |
njohnston | unit test failures look pretty high - 40% to 50% today | 16:44 |
slaweq | njohnston: correct | 16:45 |
slaweq | but again, please note that it's "just" 6 runs today | 16:45 |
slaweq | so it don't have to big problem | 16:45 |
njohnston | ok | 16:46 |
njohnston | :-) | 16:46 |
slaweq | and I think that I saw some patches with failures related to patch itself | 16:46 |
slaweq | so lets keep an eye on it :) | 16:46 |
slaweq | ok? | 16:46 |
njohnston | sounds good. We'll have better data later - I see 10 neutron jobs in queue right now | 16:47 |
slaweq | agree | 16:47 |
njohnston | FYI for those that don't know, you can put "neutron" in http://zuul.openstack.org/status to see all neutron jobs | 16:47 |
ralonsoh | btw, test_get_devices_info_veth_different_namespaces is a problem now | 16:48 |
*** links has quit IRC | 16:48 | |
ralonsoh | I see many CI jobs failing because of this | 16:48 |
ralonsoh | do we have a new pyroute2 version? | 16:48 |
slaweq | thx njohnston | 16:48 |
slaweq | ok, so as ralonsoh started with it, let's move to next topic :) | 16:48 |
slaweq | #topic fullstack/functional | 16:48 |
*** openstack changes topic to "fullstack/functional (Meeting topic: neutron_ci)" | 16:49 | |
ralonsoh | so yes, I need to check what is happening with this test | 16:49 |
slaweq | and indeed I saw this test failing today also, first I though it is maybe related to the patch on which it was run | 16:49 |
ralonsoh | I'm on it now | 16:49 |
slaweq | but now it's clear it's some bigger issue | 16:49 |
slaweq | two examples of failure: | 16:49 |
slaweq | https://a23f52ac6d169d81429a-a52e23b005b6607e27c6770fa63e26fe.ssl.cf1.rackcdn.com/679462/1/gate/neutron-functional/6d6a4c1/testr_results.html.gz | 16:49 |

ralonsoh | yes, at least is consistent | 16:50 |
slaweq | ohh, so it's now failing 100% times? | 16:50 |
ralonsoh | yes | 16:50 |
slaweq | ralonsoh: will You report bug for it? | 16:50 |
ralonsoh | yes | 16:51 |
slaweq | thx | 16:51 |
slaweq | #action ralonsoh to report bug and investigate failing test_get_devices_info_veth_different_namespaces functional test | 16:51 |
slaweq | please set it as critical :) | 16:51 |
ralonsoh | ok | 16:51 |
slaweq | thx | 16:52 |
slaweq | as I said before, I also saw 2 other failures in functional tests today | 16:52 |
slaweq | 1. neutron.tests.functional.agent.test_firewall.FirewallTestCase.test_rule_ordering_correct | 16:52 |
slaweq | https://019ab552bc17f89947ce-f1e24edd0ae51a8de312c1bf83189630.ssl.cf2.rackcdn.com/670177/7/check/neutron-functional-python27/74e7c20/testr_results.html.gz | 16:52 |
slaweq | I saw it first time | 16:52 |
slaweq | did You maybe got something similar before? | 16:53 |
ralonsoh | no, first time | 16:53 |
ralonsoh | ok, that's because we need https://review.opendev.org/#/c/679428/ | 16:53 |
slaweq | ok, I will check tomorrow exactly if this failed test_rule_ordering_correct test wasn't related to patch on which it was running | 16:54 |
*** dtrainor has quit IRC | 16:54 | |
slaweq | #action slaweq to check reason of failure neutron.tests.functional.agent.test_firewall.FirewallTestCase.test_rule_ordering_correct | 16:54 |
slaweq | ralonsoh: we need https://review.opendev.org/#/c/679428/ to fix issue with test_get_devices_info_veth_different_namespaces ? | 16:55 |
slaweq | or for what? | 16:55 |
ralonsoh | no no | 16:55 |
ralonsoh | the last one, test_rule_ordering_correct | 16:55 |

slaweq | You're fast | 16:56 |
mlavalle | he is indded | 16:56 |
slaweq | LOL | 16:57 |
slaweq | ok, and the second failed test which I saw: | 16:57 |

slaweq | but I think I already saw something similar before | 16:57 |
ralonsoh | same problem | 16:58 |
slaweq | ahh, right | 16:58 |
slaweq | different stack trace but there is list_ns_pids in it too :) | 16:58 |
slaweq | ok, so we should be better in functinal tests with Your patch | 16:58 |

clarkb | Yesterday we noticed that 4 of 8 gitea backends had stale gitconfig lockfiles which prevented gerrit git replication from happening | 19:08 |
clarkb | thank you ianw for cleaning that up | 19:08 |
clarkb | I think ianw tracked that back to poor IO performance based on journald complaints in dmesg at roughly the same time | 19:08 |
clarkb | ianw: ^ anything to add to that? | 19:08 |
clarkb | I've still not come up with a great way to work around that. Maybe we need to update gitea to clean up stale locks? | 19:09 |
ianw | i just had a thought that maybe we should put some randomisation into the git gc cron job, i think they all kick off at the same time? | 19:09 |
clarkb | they do kick off at the same time | 19:09 |
fungi | yeah, maybe staggering them will help avoid a thundering herd on the storage backend | 19:11 |
clarkb | seems like a reasonable thing to try | 19:11 |
AJaeger | good idea | 19:11 |
clarkb | ianw: do you want to write that chnage or should we find a volunteer? | 19:12 |
ianw | clarkb: just doing it now :) | 19:12 |
clarkb | great thanks | 19:12 |
clarkb | Any other opendev business before we move on? | 19:12 |
clarkb | #topic Update Config Management | 19:14 |
*** openstack changes topic to "Update Config Management (Meeting topic: infra)" | 19:14 | |
clarkb | We merged a bunch of changes from mordred to build gerrit images | 19:14 |
Shrews | clarkb: he also put up this one: https://review.opendev.org/678428 | 19:15 |
clarkb | #link https://review.opendev.org/#/q/status:open+(topic:gus2019+OR+topic:gerrit-images) Gerrit and docker related changes that need review | 19:15 |
clarkb | Shrews: cool that should be captured by the query above | 19:16 |
Shrews | yah | 19:16 |
clarkb | Would be great if people can take some time to get through those as I think interesting and useful things were learned at the gerrit user summit | 19:16 |
Shrews | any reason we haven't +Ad https://review.opendev.org/678413 yet? | 19:18 |
clarkb | Shrews: fungi notes that it will need someone to restart gerrit | 19:18 |
clarkb | I can probably work on that tomorrow | 19:19 |
fungi | yeah, alternatively it could just happen as part of the rename maintenance? | 19:19 |
*** jamesmcarthur has joined #openstack-meeting | 19:20 | |
clarkb | probably best to make sure we don't break thing as ahead of time? | 19:21 |
clarkb | just to reduce potential impacts during renames. I can likely work on that this week (today is weird as have school stuff with kids this afternoon) | 19:22 |
clarkb | Anything else? if not we'll move on to storyboard | 19:23 |
diablo_rojo_phon | Nothing currently. | 19:23 |
clarkb | #topic Storyboard | 19:24 |
*** openstack changes topic to "Storyboard (Meeting topic: infra)" | 19:24 | |
clarkb | diablo_rojo_phon: says nothing to report :) | 19:24 |
diablo_rojo_phon | I do. | 19:24 |
fungi | i did get mysql slow query logging reestablished and whip up a refreshed analysis | 19:24 |
diablo_rojo_phon | Oh cool. | 19:24 |
clarkb | oh that was for last topic then? in any case go for it on storyboard | 19:24 |

*** ralonsoh has quit IRC | 19:25 | |
fungi | now that i've worked out the process, i'm happy to do further updates for it we can compare | 19:25 |
diablo_rojo_phon | fungi: I suppose I should commence asking mordred to take a look? | 19:25 |
fungi | SotK also mentioned he might try to tease out some useful nuggets for ideas of what to improve | 19:26 |

clarkb | #link https://etherpad.openstack.org/p/201808-infra-server-upgrades-and-cleanup | 19:30 |
dmsimard | Need to pick up kids from school, if I'm not back we can talk about my topic in the infra channel | 19:30 |
clarkb | dmsimard: ok | 19:30 |
clarkb | first up is server upgrades | 19:30 |
clarkb | fungi: ^ anything new to add re wiki? | 19:30 |
fungi | not really, no | 19:30 |
clarkb | Removing/replacing static.o.o is next | 19:31 |
clarkb | #link https://etherpad.openstack.org/p/static-services | 19:31 |
fungi | other community responsibilities have taken priority this past week. i hope to pick it back up soon (but welcome anyone who wants to help out with it too) | 19:31 |
clarkb | ianw: ^ I tried to capture a todo list at the bottom of that document | 19:31 |
clarkb | ianw: can you check if it is accurate and we can start to ask for volunteers? | 19:31 |
ianw | oh sorry, yeah forgot to do that, will do | 19:32 |
clarkb | thanks | 19:32 |
clarkb | thanks | 19:32 |
clarkb | silly keyboard | 19:32 |
clarkb | Next up is AFS mirrors and debugging failures to vos release tem | 19:32 |
clarkb | *them | 19:32 |
clarkb | ianw: auristor mentioned rsync may be to blame (and possibly the switch from rsync on xenial to bionic?)) | 19:33 |
clarkb | have we learned anything concrete yet and/or are there more changes for us to review? | 19:33 |
ianw | i think fedora has locked itself again | 19:34 |
ianw | the reason is takes forever to release now is still unclear ... | 19:34 |
ianw | looking at the rysnc "-i" output, it does not do something like touch every single file | 19:34 |
fungi | you ruled out metadata being modified i guess | 19:35 |
ianw | but maybe updating the metadata on the upper directories is enough | 19:35 |
ianw | to determine this i think we need to turn on file auditing on the servers again | 19:35 |
ianw | #link https://lists.openafs.org/pipermail/openafs-info/2019-August/042861.html | 19:36 |
ianw | the only follow up was basically that version mis-match of client/server shouldn't matter ... that really only leaves bionic rsync v xenial rsync i guess :/ | 19:37 |
clarkb | at least we could rule out the version mismatch | 19:37 |
ianw | i will keep poking so we can get it stable | 19:38 |
clarkb | thanks | 19:38 |
clarkb | Next up is pointing out the current plan to do project renames on September 16 | 19:38 |
clarkb | I expect we'll do that about 7am Pacific time to get as early a start as possible? | 19:39 |
clarkb | (assuming I'm helping could be earlier if others want to drive it) | 19:39 |
clarkb | If you know of projects that need to be renamed they are highly encouraged to do that during this round of renames :) | 19:39 |
AJaeger | we should sent out an announcement... | 19:40 |
clarkb | AJaeger: good idea. I'm guessing your day is about done. I'll do that after the meeting | 19:40 |
AJaeger | thanks, clarkb | 19:41 |
clarkb | Next is PTG planning. I've been unable to spend time on this yet, but wanted to point out that it isn't too early for anyone to suggest topics | 19:42 |
clarkb | #link https://etherpad.openstack.org/p/OpenDev-Shanghai-PTG-2019 Feel free to add PTG topics | 19:42 |
clarkb | That was it for the agenda that I sent out yesterday. dmsimard are you back to talk about ara and swift hosted logs? | 19:43 |
clarkb | if not we can pick up the conversation in the infra channel as you mentioned /me gives it a few minutes before openning the floor | 19:43 |
fungi | we also tend to be pretty efficient at coming up with things to talk about or hack on at the ptg once we get into a room together | 19:46 |
clarkb | #topic Open Discussion | 19:46 |
*** openstack changes topic to "Open Discussion (Meeting topic: infra)" | 19:46 | |
fungi | i like to treat the planning list as more of a resource to help jog our memories so we don't forget things we wanted to talk about | 19:47 |
clarkb | We'll talk ara in the infra channel. Anything else before we call it a meeting | 19:47 |
fungi | nothing on my end | 19:47 |
clarkb | fungi: ++ ya its more about having good notes so that we can let the room move without spending a ton of time looking info up | 19:47 |
fungi | agreed | 19:47 |
clarkb | sounds like that is it | 19:51 |
clarkb | thank you everyone. We'll end a bit early today | 19:51 |

janders42 | good idea - I should look at this, too | 21:05 |
janders42 | what are you up to these days martial? | 21:05 |
martial | trying to train some models for ML for a Yolo test | 21:05 |
janders42 | I'm fighting our GPFS hardware, finally winning | 21:05 |

janders42 | there will be 6 | 21:06 |
janders42 | with HDR200 | 21:07 |
janders42 | so should be good | 21:07 |
janders42 | this is evolution of our BeeGFS design - more balanced, non-blocking in terms of PCIe bandwidth | 21:07 |
martial | that is quite good | 21:07 |
janders42 | unfortunately the interconnect doesnt fully work yet, but I'll be at the DC later this morning hopefully getting it to work | 21:08 |
janders42 | have you ever looked at k8s/GFPS integration? | 21:08 |
janders42 | this is meant to be HPC OpenStack storage backend and HPC storage backend but I think there's some interesting work happening in k8s-gpfs space | 21:09 |
*** bbowen has joined #openstack-meeting | 21:09 | |
martial | I confess we have not had the need for now | 21:10 |
martial | what are your reading recommendations on this topic? | 21:10 |
janders42 | I think all I had was some internal email from IBM folks | 21:11 |
janders42 | I hope to learn more about this in the coming months - and will report back | 21:11 |
martial | that would indeed be useful | 21:12 |
martial | maybe a small white paper on the subect? | 21:13 |

martial | #chair b1airo | 21:14 |
openstack | Current chairs: b1airo martial | 21:14 |
janders42 | if it will be possible to remote into Shanghai SIG meetup, I can give a lightning talk about GPFS as OpenStack and/or k8s backend | 21:14 |
janders42 | hey Blair! | 21:14 |
b1airo | o/ | 21:14 |
b1airo | issues connecting today sorry | 21:14 |
janders42 | another "interesting" thing I've come across lately is how Mellanox splitter cables work on some switches | 21:14 |
b1airo | how goes it janders42 | 21:14 |
martial | not sure if Stig will have that capability at the Scientific SIG meet in Shanghai but I hope so | 21:14 |
b1airo | i'd be keen to see that lightning talk janders42 | 21:15 |
janders42 | yeah that would be great! :) - unlikely I will be able to attend in person at this stage | 21:15 |
martial | not sure if Blair will be there. I will not | 21:15 |
martial | (Shanghai) | 21:15 |
janders42 | I plugged a 50GE to 4x10gE cable into my mlnx-eth switch yesterday and enabled the splitter function on the port | 21:16 |
janders42 | and the switch went "port eth1/29 reconfigured. Port eth1/30 reconfigured" | 21:16 |
janders42 | erm... I did NOT want to touch port 30 - it's an uplink for an IPMI switch... | 21:16 |
janders42 | boom | 21:17 |
janders42 | another DC trip | 21:17 |
janders42 | nice "feature" | 21:17 |
janders42 | with some switches it is possible to use splitters and still use all of the ports | 21:17 |
janders42 | with others - the above happens - connecting a splitter automagically kills off the port immediately below | 21:17 |
*** rmcall has joined #openstack-meeting | 21:17 | |
janders42 | oh well lesson learned | 21:17 |
janders42 | hopefully will undo this later this morning | 21:18 |
*** ociuhandu has quit IRC | 21:18 | |
martial | or maybe you will lose your uplink ... <disconnect> | 21:18 |
martial | (that's why we love technology :) ) | 21:19 |
b1airo | no, i won't make it to Shanghai. already have a couple of trips before the end of the year and another to the States early Jan | 21:19 |
martial | joining us in Denver ? | 21:20 |
janders42 | Denver = SC? | 21:20 |
b1airo | janders42: iirc that functionality is documented regarding the breakout ports | 21:20 |
janders42 | yeah... @janders | 21:21 |
janders42 | RTFM | 21:21 |
janders42 | :D | 21:21 |
janders42 | just quite counter-intuitive | 21:21 |
martial | SC yes | 21:21 |
b1airo | reconfiguring the port requires a full switchd restart and associated low-level changes, which interrupts all the way down to L2 i guess | 21:21 |
b1airo | SC yes | 21:22 |
janders42 | just looked at the calendar and SC19 and Kubecon clash | 21:22 |
janders42 | I'm hoping to go to Kubecon | 21:22 |
janders42 | otherwise would be happy to revisit Denver | 21:22 |
janders42 | how long of a trip is it for you Blair to get to LAX? 14 hrs? Bit closer than from here I suppose.. | 21:22 |
b1airo | yeah bit closer, just under 12 i think | 21:23 |
janders42 | nice! | 21:23 |
b1airo | usually try to fly via San Fran though | 21:24 |
janders42 | yeah LAX can be hectic | 21:24 |
janders42 | I quite like Dallas | 21:24 |
janders42 | very smooth | 21:24 |
janders42 | good stopover while heading to more central / eastern parts of the States | 21:24 |
janders42 | not optimal for San Diego though - that'd be a LAX/SFO connection | 21:25 |
martial | (like I said a very AOB meeting today ;) ) | 21:25 |
janders42 | since Blair is here I will re-post the GPFS node benchmarks | 21:26 |

janders42 | this is from a single node with 12NVMes - no GPFS yet | 21:26 |
janders42 | but we did manage to get a 12NVMe non-blocking PCIe topology going | 21:26 |
janders42 | 39GB/s read 27GB/s write | 21:26 |
janders42 | we'll have six of those puppies on HDR200 so should be good | 21:27 |
janders42 | but having said that I need to head off to the DC soon to bring this dropped out IPMI switch back on the network - otherwise I can't build the last node.,, | 21:27 |
b1airo | would be interesting to see how those numbers change with different workload characteristics | 21:28 |
janders42 | bad news is I haven't found any way whatsoever to build these through Ironic | 21:28 |
*** rmcall has quit IRC | 21:28 | |
janders42 | 14 drives per box booting thru UEFI from drives number 8 and 9 is too much of an ask | 21:28 |
b1airo | but those look like big numbers for relatively low depth | 21:28 |
janders42 | and these drives need to be SWRAID, too | 21:28 |
janders42 | I think there's a fair bit of room for tweaking, this was just to prove that the topology is right | 21:29 |
janders42 | it would be very interesting to see how the numbers stack up against our IO500 #4 BeeGFS cluster | 21:30 |
b1airo | what's the GPFS plan with these? declusered raid? | 21:30 |
janders42 | in the ten node challenge | 21:30 |
janders42 | GPFS-EC | 21:30 |
*** markvoelker has joined #openstack-meeting | 21:31 | |
janders42 | though we will run 4 nodes of EC and 2 nodes of non-EC just to understand the impact (or lack of) of EC on throughput/latency | 21:31 |
janders42 | for prod it will be all EC | 21:31 |
janders42 | the idea behind this system is a mash up of Ceph style arch, RDMA transport and NVMes connected in a non-blocking fashion | 21:32 |
janders42 | hoping to get the best of all these worlds | 21:32 |
janders42 | so far the third bit looks like a "tick" | 21:32 |
janders42 | these run much smoother than our BeeGFS nodes in the early days | 21:32 |
janders42 | these do have some blocking which is causing all sorts of special effects if not handled carefully | 21:33 |
janders42 | the new GPFSes have none | 21:33 |
janders42 | which gets a little funny cause people hear this and ask me - so what's the difference between BeeGFS and GPFS, why do we need both? | 21:34 |
janders42 | I used to say BeeGFS is a Ferrari and GPFS is a beefed up Ford Ranger | 21:34 |
b1airo | ha! | 21:34 |
janders42 | but it really comes to a Ferrari and Porsche Cayenne now really | 21:34 |
*** markvoelker has quit IRC | 21:35 | |
b1airo | i guess a lot of it comes down to the question of what happens when either a) the network goes tits up, and/or b) the power suddenly goes out from a node/rack/room | 21:35 |
janders42 | all good questions | 21:35 |
janders42 | and with BeeGFS I have a catch-all answer | 21:35 |
janders42 | it's scratch | 21:35 |
janders42 | it's not backed up | 21:35 |
janders42 | if it goes it goes | 21:35 |
b1airo | i.e., do you still have a working cluster tomorrow :-), and is there any data still on it | 21:35 |
janders42 | GPFS on the other hand... ;) | 21:36 |
b1airo | get out of jail free card ;-) | 21:36 |
janders42 | if one was to go through a car crash, I recommend being in the Cayenne not the Ferrari | 21:36 |
janders42 | let's put it this way | 21:36 |
janders42 | but yeah it's an interesting little project | 21:37 |

janders42 | if it wasnt all the drama with HDR VPI firmware slipping and splitter cables giving us shit it would be up and running by now | 21:37 |
janders42 | hopefully another month | 21:37 |
janders42 | and on that note I better start getting ready to head out to the DC to fix that IPMI switch.. | 21:37 |
janders42 | we got mlnx 1GE switches with Cumulus on them for IPMI | 21:38 |
janders42 | I can't remember why | 21:38 |
janders42 | they are funky, but it is soo distracting switching between mlnx-os and cumulus | 21:38 |
janders42 | completely different philosophy and management style | 21:38 |
janders42 | probably wouldnt get those again - just some braindead cisco like ones for IPMI | 21:38 |
janders42 | MLNX-100GE and HDR ones are great to work with though | 21:39 |
janders42 | (except the automatic shutdown of the other port when enabling splitters :) ) | 21:39 |
b1airo | if you go Cumulus all the way then you can obviously get 1G switches too, but then bye bye IB | 21:39 |
b1airo | i'm slightly distracted in another Zoom meeting now sorry | 21:40 |
janders42 | no worries | 21:40 |
janders42 | wrapping up here, too | 21:40 |
janders42 | I hope I haven't bored you to death with my GPFS endeavours | 21:40 |
b1airo | no, sounds fun! | 21:41 |
janders42 | if you happen to have a cumulus-cisco cheat sheet I'd love that | 21:41 |
janders42 | I wish I could just paste config snippets to Google Translate | 21:41 |
janders42 | :D | 21:41 |
martial | with that, should we move to AOB? :) | 21:44 |
martial | If not, I will propose we adjourn Today's meeting | 21:45 |
martial | see you all next week | 21:47 |
martial | #endmeeting | 21:47 |
