| openstack | The meeting name has been set to 'neutron_l3' | 14:01 |
| liuyulong | After reading the bug list, IMO, there were two quiet weeks. | 14:02 |
| liuyulong | Let's start | 14:03 |
| liuyulong | #topic Bugs | 14:03 |
| *** openstack changes topic to "Bugs (Meeting topic: neutron_l3)" | 14:03 | |

| liuyulong | First one | 14:04 |
| slaweq | hi | 14:04 |
| liuyulong | #link https://bugs.launchpad.net/neutron/+bug/1920975 | 14:04 |
| openstack | Launchpad bug 1920975 in neutron "neutron dvr should lower proxy_delay when using proxy_arp" [Medium,In progress] - Assigned to Edward Hope-Morley (hopem) | 14:04 |
| *** GlaciErrDev has joined #openstack-meeting | 14:04 | |
| liuyulong | #link https://review.opendev.org/c/openstack/neutron/+/782570 | 14:04 |
| liuyulong | ^^ It has a patch here. | 14:04 |
| liuyulong | I left some comments, but no response for now. | 14:04 |
| liuyulong | Make the constant name more accurate. | 14:05 |
| liuyulong | But my final idea is to hide that kernel algorithm, all we want is to delay no longer than 50ms. | 14:06 |
| liuyulong | But the unit jiffies is not fixed value. | 14:06 |
| liuyulong | It is based on the kernel config of HZ. | 14:07 |
| liuyulong | (^^ a long story, please take a look at https://github.com/torvalds/linux/blob/master/include/linux/jiffies.h) | 14:07 |
| * slaweq will be back in few minutes | 14:07 | |
| liuyulong | So, let's wait until the author's response. | 14:07 |
| liuyulong | Next | 14:09 |
| liuyulong | #link https://bugs.launchpad.net/neutron/+bug/1922653 | 14:09 |
| openstack | Launchpad bug 1922653 in neutron "[L3][Port forwarding] multiple floating_ip:port to same internal fixed_ip:port (N-to-1 rule support)" [Undecided,New] | 14:09 |
| liuyulong | It was reported by me. | 14:09 |
| liuyulong | This is coming from our customers, they want to set such N-1 rules. | 14:09 |
| liuyulong | But it is not available for neutron now. | 14:09 |
| liuyulong | After some deep looking at this constraint, IMO, it is a bit rigid. | 14:10 |
| liuyulong | We can remove that constraint for multiple floating_ip:port to same internal fixed_ip:port. | 14:11 |
| liuyulong | My local testing shows that all works fine. It will be a quite simple change of DB migration script only. | 14:11 |
| liuyulong | No real code change needed for L3 DB, port forwarding plugin and L3 agent. | 14:12 |
| liuyulong | OK, no more bugs from me now. | 14:12 |
| liuyulong | But, we have some RFEs. | 14:13 |

| liuyulong | #link https://bugs.launchpad.net/neutron/+bug/1921126 | 14:13 |
| openstack | Launchpad bug 1921126 in neutron "[RFE] Allow explicit management of default routes" [Wishlist,New] - Assigned to Bence Romsics (bence-romsics) | 14:13 |
| liuyulong | It was approved, and the spec has been uploaded. | 14:14 |
| liuyulong | #link https://review.opendev.org/c/openstack/neutron-specs/+/781475 | 14:14 |
| liuyulong | Looks good to me now, just some questions about how to deal with the original default route. | 14:15 |
| liuyulong | It can be used to fix the bug https://bugs.launchpad.net/neutron/+bug/1901992 | 14:15 |
| openstack | Launchpad bug 1901992 in neutron "Original default route in DVR SNAT namespace is not recovered after creating and deleting /0 extraroute" [Medium,Triaged] - Assigned to gao yu (gaoyublack) | 14:15 |
| liuyulong | Next | 14:17 |
| liuyulong | #link https://bugs.launchpad.net/neutron/+bug/1921461 | 14:17 |
| openstack | Launchpad bug 1921461 in neutron "[RFE] Enhancement to Neutron BGPaaS to directly support Neutron Routers & bgp-peering from such routers over internal & external Neutron Networks" [Undecided,New] | 14:17 |
| liuyulong | It is BGP related request for neutron router, the spec is here: https://review.opendev.org/c/openstack/neutron-specs/+/783791 | 14:17 |
| liuyulong | It looks like the neutron router will run BGP daemons after this. | 14:20 |
| liuyulong | Something like neutron-dynamic-routing agent do, maybe this can be achived by this: | 14:20 |
| liuyulong | 1. Add API to neutron like this spec described | 14:21 |
| lajoskatona | It's a huge topic, and perhaps it can be later cut to smaller specs | 14:21 |
| *** dsariel has quit IRC | 14:22 | |
| *** dsariel has joined #openstack-meeting | 14:22 | |
| liuyulong | 2. Let the L3 agent and the bgp-dr-agent has some interact to learn/broadcast the routes. | 14:22 |
| liuyulong | lajoskatona, yes, it is | 14:22 |
| *** yamamoto has quit IRC | 14:23 | |
| liuyulong | For now, based on the spec, I may say the request has many functions similar to neutron-dynamic-routing. | 14:24 |
| lajoskatona | exactly, I am not sure that all can fit to ndr code base or some core Neutron changes are necessary for it | 14:25 |
| liuyulong | So let's wait and comment the spec until it get sharping. | 14:25 |
| lajoskatona | Not sure if it was discussed on drivers meeting | 14:26 |
| lajoskatona | perhaps it was not due to Easter time | 14:26 |
| liuyulong | Yes, no response in LP for now. | 14:26 |
| lajoskatona | so there it can have some more feedback | 14:26 |
| liuyulong | OK, next one, https://bugs.launchpad.net/neutron/+bug/1922716, it looks duplicated to https://bugs.launchpad.net/neutron/+bug/1907089 | 14:27 |
| openstack | Launchpad bug 1922716 in neutron "[RFE] BFD for BGP Dynamic Routing" [Undecided,New] | 14:27 |
| openstack | Launchpad bug 1907089 in neutron "[RFE] Add BFD support for Neutron" [Wishlist,New] - Assigned to Lajos Katona (lajos-katona) | 14:27 |
| *** baojg has quit IRC | 14:27 | |
| lajoskatona | Yeah BFD for BGP is from Manu as well (He is from Ericsson/EST as well) | 14:27 |
| liuyulong | So maybe you guys can share some thoughts during the PTG. :) | 14:28 |
| lajoskatona | For BFD support in neutron I am working on to have a working prototype, but I think that is now independent of the proposed API in the spec | 14:28 |
| lajoskatona | yeah, I plan to add section to the etherpad and ask Manu as well to join :-) | 14:28 |
| liuyulong | Cool | 14:29 |
| *** ociuhandu has quit IRC | 14:30 | |
| liuyulong | One note, the real use case is essential for this proposal. Manu's idea, IMO, is to monitor the BGP routes. | 14:31 |
| liuyulong | Your spec is now for ECMP routes? | 14:31 |
| *** ociuhandu has joined #openstack-meeting | 14:31 | |
| liuyulong | But, basically, all for L3 router's route entries. | 14:31 |
| lajoskatona | not just ECMP, but for extra/static routes | 14:32 |
| lajoskatona | yes as You say | 14:32 |
| liuyulong | OK, no more RFEs from me now. | 14:33 |

| openstack | The meeting name has been set to 'swift' | 21:00 |
| timburke | who's here for the swift meeting? | 21:01 |
| rledisez | o/ | 21:01 |
| mattoliverau | o/ | 21:01 |
| acoles | o/ | 21:02 |
| *** clayg has joined #openstack-meeting | 21:03 | |
| timburke | as usual, the agenda's at https://wiki.openstack.org/wiki/Meetings/Swift | 21:03 |
| clayg | o/ | 21:03 |
| timburke | but first, i want to insert a topic ;-) | 21:04 |
| timburke | #topic rledisez | 21:04 |
| *** openstack changes topic to "rledisez (Meeting topic: swift)" | 21:04 | |
| zaitcevx | o/ | 21:05 |
| timburke | rledisez just proposed https://review.opendev.org/c/openstack/swift/+/785276 -- it looks like he won't be working on swift much more | 21:05 |
| timburke | i just wanted to say, thank you for doing so much for (and with) swift over the years | 21:05 |
| rledisez | it's really been a pleasure all these years to work with you guys. I can't imagine a better team for an open source project | 21:06 |
| rledisez | I'll miss Swift for sure, but I know you'll continue to make it the best object storage software ;) | 21:06 |
| zaitcevx | What does it mean for Swift at OVH? Are you guys shutting it down, and if yes, what's the replacement? Something OpenIOish? | 21:06 |
| rledisez | quickly: short term there is no plan to shut it down. you don't shutdown hundreds of PB easily 😅. long term it will surely be replaced by "something openioish" | 21:07 |
| timburke | i'd forgotten to mention it before, but we had an internal user looking for some swift storage who said, "I like using ovh for my personal projects and I was really quite pleased with how easy it was to hook up the swift object storage to my build system" :-) | 21:07 |
| acoles | rledisez: thanks for all your fantastic contributions, you'll be missed. au revoir | 21:08 |
| mattoliverau | :( | 21:08 |
| clayg | rledisez: thank you! | 21:08 |
| zaitcevx | Thanks rledisez for all the work, and I'm bummed that queue-less request submission didn' | 21:09 |
| zaitcevx | t work with py2 | 21:09 |
| zaitcevx | Completely stumped me. | 21:09 |
| rledisez | zaitcevx: yeah, one of the most brainfuck thing I failed I think | 21:10 |

| timburke | i hope we eventually cross paths again :-) always feel free to pop in and see how we're doing | 21:11 |
| timburke | especially at events like... | 21:11 |
| timburke | #topic ptg | 21:11 |
| *** openstack changes topic to "ptg (Meeting topic: swift)" | 21:11 | |
| clayg | 🤣 nice transistion | 21:12 |
| timburke | looks like we're starting to get the etherpad filled out | 21:12 |
| timburke | #link https://etherpad.opendev.org/p/swift-ptg-xena | 21:12 |
| timburke | i'll try to get some more stuff on there today | 21:13 |
| mattoliverau | yeah I just brandumped some possible topics | 21:13 |
| timburke | (though part of me feels like we could spend an *awful lot* of time just thinking hard about tsync & replication 😉) | 21:13 |
| timburke | next up | 21:14 |
| timburke | #topic part power increase | 21:15 |
| *** openstack changes topic to "part power increase (Meeting topic: swift)" | 21:15 | |
| timburke | the relinker now has a workers option! and it defaults to <# disks> | 21:15 |
| timburke | i still want to play with moving more than one step at a time -- so https://review.opendev.org/c/openstack/swift/+/781591 is rebased (though it still needs tests) | 21:17 |
| timburke | and i know mattoliverau is still working on getting relinker status into recon | 21:17 |
| mattoliverau | nice, so it's getting better and better :) | 21:18 |
| clayg | it's already pretty damn good | 21:18 |
| clayg | @timburke @mattoliverau is there any doc update that would be required to help people with their first PPI (or have most of the changes been "in the backend") | 21:19 |
| timburke | at nvidia, we just finished another increase and it was our smoothest one yet -- down to ~27hrs, and no hacking together of scripts to run against prod :-) | 21:19 |
| mattoliverau | relinker does help you find bad disks though :P | 21:20 |
| mattoliverau | clayg: oh yeah we should look at our current ppi doc, there are alot more options so we should mention them. | 21:21 |
| timburke | clayg, excellent question! i think users get most of the new goodness "for free", but i'll make a note to review our existing docs. surely, it should have something about taking a config file if it doesn't already | 21:21 |
| timburke | that's all i've got for that | 21:22 |
| timburke | #topic sharding / shrinking | 21:22 |
| *** openstack changes topic to "sharding / shrinking (Meeting topic: swift)" | 21:22 | |
| clayg | on shrinking I'm most excited about counting tombstones for the purpose of shrinking 🤩 (go acoles !!!) | 21:23 |
| acoles | oh yeah, I made some progress on that since last week https://review.opendev.org/c/openstack/swift/+/782832 | 21:23 |
| mattoliverau | nice | 21:23 |
| timburke | yeah, that seems great! and we get it as a side-effect of other work we're already doing! | 21:23 |
| acoles | but it messes up probe tests, some of which rely on (auto)shrinking immediately after deleting objects :( so I need to figure out the best approach to rectify that | 21:24 |
| acoles | for now I added a --reclaim-age option to sharder cli so I can get rid of the tombstones immediately (With --reclaim-age=0) in the probe test | 21:25 |
| timburke | we already open up the broker, right? maybe do a manual reclaim? or that ;-) | 21:25 |
| acoles | it's a little frustrating how the probe tests have to work around auto-sharding doing its thing | 21:26 |
| clayg | there's some other test where we say "go forward in time a reclaim age" as an explination of reclaim-age=0 | 21:26 |
| clayg | acoles: yeah, do we have probetests running with both auto-sharding AND using s-m-s-r directly? | 21:27 |
| acoles | *not yet* ... but that was another option I considered | 21:27 |
| acoles | i.e. to execute the shrinks 'manually' with s-m-s-r in place of the autoshrinking points in the test | 21:28 |
| timburke | clayg, all in one test, or some tests that exercise one, and some that exercise the other? we've got the latter but not the former | 21:28 |
| acoles | tes, what timburke said ^^ | 21:28 |
| acoles | yes* | 21:28 |
| *** jmasud has quit IRC | 21:29 | |
| timburke | (though as i recall that required that we introduce a --no-auto-sharding option or the like) | 21:29 |
| clayg | yes, I wasn't clear - that matches my understanding | 21:29 |
| timburke | oh yeah, and zaitcevx proposed https://review.opendev.org/c/openstack/swift/+/784617 to have swift-recon aggregate sharding info | 21:29 |
| clayg | but I guess Al is looking at breaking existing auto-shard tests 🤔 | 21:29 |
| timburke | does that mean you're been doing some sharding on train? how's it going? | 21:30 |
| zaitcevx | That patch can be expanded for something sharding-specific, maybe some calculations or whatnot. | 21:30 |
| acoles | clayg: yes, some existing auto- tests break because they don't shrink anymore :'( cos of tombstones | 21:30 |
| clayg | @acoles 👍 | 21:30 |
| zaitcevx | timburke: I'm still experimenting with Train, but I see no showstoppers yet. Anyway, any further backports to Train get too hard. I tried to walk a little up the tree. So, bugfixes only now. | 21:31 |
| clayg | so you're considering "migrating" the "broken" auto-tests to manual (do we have manual tests of shrinking already?) | 21:31 |
| *** lbragstad has quit IRC | 21:32 | |
| acoles | clayg: we do already have manual test for compact. I'm undecided how to deal with the breaking auto tests - either migrate wholly or partly to manual , or allow reclaim-age to be overridden | 21:33 |
| mattoliverau | mayber the fake sharder for autosharding can have a reclaim of 0 or something short that we can sleep on, or can mock a reclaim or something. | 21:34 |
| acoles | I'm leaning towards migrating partly to manual (where we need to override auto- behaviour) | 21:34 |
| mattoliverau | once we have shrinking/compact working, tested and happy with it, and analyze and repair.. we'd be closer to re-vamping autosharding to maybe actaully be stable ;) | 21:35 |
| mattoliverau | we almost have all the peices.. we just need to gain some confidence in them first | 21:36 |
| mattoliverau | but yeah for now whatever we need (part manual or whatever) to make sure the probes pass. it's good work and tomb stones added to the mix makes it much nicer! great work | 21:37 |
| acoles | I suppose the probe test failures at least add confidence that the tombstones are being considered before shrinking :D | 21:37 |
| *** zaneb has quit IRC | 21:37 | |
| mattoliverau | lol | 21:38 |
| clayg | WTG probe tests! | 21:38 |
| timburke | i was just thinking that -- they're breaking because we're doing the right thing now :-) | 21:38 |
| timburke | all right | 21:38 |
| *** spotz has joined #openstack-meeting | 21:38 | |
| timburke | one more impromptu topic | 21:38 |
| timburke | #topic meeting next week | 21:38 |
| *** openstack changes topic to "meeting next week (Meeting topic: swift)" | 21:38 | |
| timburke | i'm going to be out, camping -- does anyone want to chair the meeting next week? | 21:39 |
| zaitcevx | I'm going to be away next week. Well, I hope. | 21:39 |
| timburke | or we just skip it :-) | 21:39 |
| mattoliverau | how many is left before the PTG | 21:39 |
| acoles | it's my birthday so I may (will) not come - I feel a cancellation coming here :) | 21:39 |
| kota_ | rledisez: thanks for working for Swift, I quickly catch up the meeting back log and found your proposed https://review.opendev.org/c/openstack/swift/+/785276 | 21:39 |
| timburke | it'd be our last meeting before the ptg, but otoh, we haven't had that many new topics to talk about | 21:40 |
| acoles | PTG is week after right? | 21:40 |
| kota_ | oops, i wrote to meeting channel... sorry for the interruption :/ | 21:40 |
| mattoliverau | cool. Fine to skip so long as poeple fill out the etherpad on topics. That | 21:40 |
| mattoliverau | that's the only thing we'd remind in the meeting next week :) | 21:40 |
| timburke | and then, of course, we'll skip the one during the ptg since we'll have plenty of contact already | 21:41 |
| timburke | so, next meeting: April 28th | 21:42 |
| mattoliverau | yeah, well we'll be in virtual person that week :) | 21:42 |
| timburke | that's all i've got | 21:42 |
| timburke | #topic open discussion | 21:42 |
