openstack | Launchpad bug 1835044 in neutron "[Queens] Memory leak in pyroute2 0.4.21" [High,Won't fix] - Assigned to Rodolfo Alonso (rodolfo-alonso-hernandez) | 14:06 |
liuyulong_ | This is now marked as wont-fix. | 14:06 |
ralonsoh | yes | 14:06 |
liuyulong_ | But for this popular rpm repo, we still do not have a new version of pyroute2 for queens release. | 14:07 |
ralonsoh | because we can't modify stable requirements | 14:07 |
liuyulong_ | #link http://mirror.centos.org/centos/7.6.1810/cloud/x86_64/openstack-queens/ | 14:07 |
liuyulong_ | It is still python2-pyroute2-0.4.21-1.el7.noarch.rpm | 14:07 |
slaweq | hi | 14:07 |
ralonsoh | each company should fix this | 14:07 |
ralonsoh | we are pushing the changes for our RPM repos | 14:07 |
ralonsoh | but this won't be changed in a stable branch unless this is a security problem | 14:08 |
liuyulong_ | So R and S repo have new version? | 14:08 |
ralonsoh | in devstack/requirements yes | 14:09 |
ralonsoh | not Q | 14:09 |
ralonsoh | 0.5.2 vs 0.4.21 | 14:09 |
liuyulong_ | Our environment are all running queens, we indeed need a repo fix. : ) | 14:10 |
liuyulong_ | ralonsoh, thank you for working on this. | 14:10 |

openstack | Launchpad bug 1834308 in neutron "[DVR][DB] too many slow query during agent restart" [Medium,Confirmed] - Assigned to LIU Yulong (dragon889) | 14:10 |
ralonsoh | my pleasure | 14:10 |
liuyulong_ | I will submit a fix for DVR related DB query. | 14:11 |
*** ttsiouts has quit IRC | 14:11 | |
liuyulong_ | Our DBA help me to get some slow query LOG. | 14:11 |

*** liuyulong has joined #openstack-meeting | 14:12 | |
liuyulong | sorry lost the connection again.... | 14:13 |
liuyulong | We noticed there will be 300k+ slow query (0.5s+) during 30 nodes ovs-agent restart. | 14:13 |
liuyulong | Yeah, most of them are related to DVR | 14:14 |

liuyulong | #link https://bugs.launchpad.net/neutron/+bug/1835663 | 14:14 |
openstack | Launchpad bug 1835663 in neutron "Some L3 RPCs are time-consuming especially get_routers" [Medium,Confirmed] | 14:14 |
liuyulong | As you noticed, it is really slow. | 14:14 |
liuyulong | http://logs.openstack.org/11/669111/4/check/neutron-tempest-plugin-dvr-multinode-scenario/dc3af26/controller/logs/screen-q-l3.txt.gz#_Jul_07_04_18_11_791730 | 14:14 |
liuyulong | IMO, 37s for a single RPC, this is not acceptable for a production environment. My OP colleagues will complain. : ) | 14:15 |
*** ttsiouts has quit IRC | 14:16 | |
*** liuyulong_ has quit IRC | 14:16 | |
liuyulong | Neutron server side DB slow query may be one reason. | 14:16 |
haleyb | liuyulong: ack, and that log was from a check job? that's pretty bad | 14:18 |
liuyulong | For this log here, maybe upstream CI neutron server just meet its bottleneck. It can not answer too much RPC calls concurrently. | 14:19 |
liuyulong | haleyb, yes, it is bad | 14:19 |
liuyulong | #link https://review.opendev.org/#/c/669111/ | 14:20 |
liuyulong | ralonsoh, slaweq, hi, this patch ^^ | 14:20 |
ralonsoh | there is an implementation for this function | 14:21 |
liuyulong | The time cost wrapper, I left some comments | 14:21 |
ralonsoh | I'll review it after the meeting | 14:21 |
liuyulong | ralonsoh, yes, it's good to know we have similar function already. | 14:21 |
*** ttsiouts has joined #openstack-meeting | 14:22 | |
liuyulong | Let me quote the comment here: | 14:22 |
liuyulong | but it can not distinguish each call for same RPC, so I will still add a wrapper here which call that function inside. And a log for the function start is needed as well. We need to know the precisely call start and end. | 14:23 |
njohnston | yes exactly I think that if you override the message argument to the oslo.utils time_it function and add the generated uuid then you get the benefit of the function | 14:23 |
ralonsoh | njohnston, agree | 14:24 |
njohnston | but you could do that without a separate decorator | 14:24 |
*** bobh has joined #openstack-meeting | 14:25 | |
liuyulong | njohnston, how to enable the start log without a new decorator? | 14:25 |
*** zbitter has joined #openstack-meeting | 14:26 | |
liuyulong | We may want to see what happened between start and end. | 14:26 |
liuyulong | time_it just log the duration. | 14:26 |
njohnston | @osloutils.time_it(message="time-cost: %(seconds).02f seconds to run function '%(func_name)s', uuid=" + uuidutils.generate_uuid()) | 14:27 |
njohnston | I see, so you believe there is value in having the "call: start" separate from the "call: ended, time = %d" log messages | 14:29 |
*** yamamoto has joined #openstack-meeting | 14:29 | |
njohnston | I can see your point | 14:29 |

slaweq | I agree with liuyulong that separate log for start and end can be useful | 14:31 |
liuyulong | And I have another concern, that 'StopWatch' is used in the 'time_it'. It looks pretty complicated, don't know if it will cause something wrong in RPC calls. | 14:31 |
ralonsoh | this is just a context manager | 14:31 |
liuyulong | OK, I will refactor this decorator. | 14:33 |
liuyulong | It will be useful for upstream CI | 14:33 |
liuyulong | I have no bug today, last week is a bit quite for L3. | 14:35 |
ralonsoh | I still have one bug in L3 | 14:36 |

liuyulong | Recently we meet many exceptions about DHCP during some upgrading or restarting. | 14:39 |
*** altlogbot_3 has joined #openstack-meeting | 14:39 | |
liuyulong | And I'm deciding to remove the DHCP agent in our local environment. | 14:39 |
liuyulong | config_drive or L2-agent self-sevice DHCP looks more friendly to large scale cloud. | 14:40 |
slaweq | liuyulong: there is RFE about distributed dhcp agent | 14:41 |

liuyulong | Yes, all from our OPs complain. | 14:42 |

*** altlogbot_3 has quit IRC | 14:42 | |
slaweq | liuyulong: no, this one isn't related to OVN | 14:42 |
liuyulong | amotoki, it is a local implementation. | 14:42 |
amotoki | liuyulong: okay, is it a kind of distributed one? | 14:43 |
liuyulong | amotoki, since OVS-agent have full acknowage of port IP and MAC. | 14:43 |
*** belmoreira has joined #openstack-meeting | 14:43 | |
slaweq | amotoki: I remember when I was in OVH we also had something like that - neutron-ovs agent was spawning simple udhcpd service for each port on host - and that worked very well :) | 14:43 |
amotoki | liuyulong: slaweq: thanks. it reminds me of nova-network dhcp stuff per compute node. | 14:44 |
amotoki | the proposed distributed dhcp agent would be similar. | 14:44 |

jungleboyj | Doesn't look like it. | 16:07 |
*** Liang__ is now known as LiangFang | 16:07 | |
Roamer` | jungleboyj, are you asking about new drivers, or the other deadline related to milestone 2? Because we are working on restarting the StorPool CI as we speak, it should be up and running in the next couple of days, with Python 3 jobs and all | 16:07 |
LiangFang | o/ | 16:07 |
jungleboyj | So, don't really have any requests for driver reviews then since no one is updating the code. | 16:08 |
*** ijw has joined #openstack-meeting | 16:08 | |
jungleboyj | Roamer`: Wasn't asking about Py37 requirement just yet but that is the next topic. | 16:08 |
jungleboyj | Glad you guys are making progress there. | 16:09 |
jungleboyj | There was some confusion as to the deadlines. | 16:09 |
*** tssurya has quit IRC | 16:09 | |
Roamer` | well, to be honest, we did notice that we have sort of forgotten to declare a couple of capabilities for the StorPool driver, and there is also an almost trivial way to implement snapshot revert... I *know* we may even be famous for coming in with last-minute request, but, supposing we manage to get our CI up and running and we submit some patches and it votes on them, is there a chance we | 16:10 |
jungleboyj | Your CI needs to be running py37 by Milestone 2 or an unsupported patch will be pushed up. | 16:10 |
Roamer` | would make it? | 16:10 |
*** ttsiouts has quit IRC | 16:10 | |
jungleboyj | If the py37 isn't passing by milestone 3 then the unsupported patch will be merged at that point. | 16:10 |
jungleboyj | Yes, I do believe last minute requests are a specialty. | 16:11 |
jungleboyj | Is there a new driver review out there to go with your CI? | 16:11 |
jungleboyj | Roamer`: ? | 16:12 |
Roamer` | sorry, I'm not really sure exactly what you're asking right now... there is no new StorPool driver, there may be three very minor changes, we have not submitted them for review yet. | 16:12 |
*** Lucas_Gray has quit IRC | 16:13 | |
jungleboyj | Oh, I thought you were asking about a new driver. | 16:13 |
jungleboyj | I see that storpool is still out there. | 16:14 |
jungleboyj | Ok, so it is out there and supported. | 16:15 |
jungleboyj | So, you just need to have your CI running using py37. | 16:15 |
jungleboyj | If you have fixes to push up then we can merge them once you are passing 3rd Party CI tests. | 16:16 |
*** gyee has joined #openstack-meeting | 16:16 | |
Roamer` | ok, thanks a lot, and sorry for blindsiding you yet again | 16:16 |
jungleboyj | Moving on. | 16:16 |
jungleboyj | I have gotten a Train release created in Launchpad. | 16:16 |
jungleboyj | Sorry I hadn't done that before. Had opened a page to do it several times and got distracted. | 16:17 |
jungleboyj | Anyway, it is there now. Take a look at it and let me know if there is anything that doesn't look right. | 16:17 |
jungleboyj | I need to update our PTL process documentation with a note on that. | 16:17 |
jungleboyj | #topic Mid-Cycle Meeting | 16:17 |
*** openstack changes topic to "Mid-Cycle Meeting (Meeting topic: Cinder)" | 16:17 | |
jungleboyj | So, we have had a bit of a hiccup in our mid-cycle plan. | 16:17 |
jungleboyj | We planned it for a date that worked for Sean and I to be in RTP to meet up with Locals, eharney hemna rosmaita tbarron | 16:18 |
jungleboyj | Was hoping to get others to come as well. | 16:18 |
jungleboyj | Now it sounds like smcginnis Can't make it. | 16:18 |
jungleboyj | Trying to figure out if we try to find another date or if we move on without smcginnis | 16:19 |
jungleboyj | eharney: hemna rosmaita Particularly looking for input from you guys. | 16:19 |
jungleboyj | Do you think we can have a productive meeting with 4 of us plus remote people? | 16:20 |
jungleboyj | *Hello? Is this thing on!?!* | 16:21 |
rosmaita | yes, though it would be even better with smcginnis ... what are the date change options? | 16:21 |
jungleboyj | We could maybe move it a week later but then I think we lose hemna | 16:22 |
jungleboyj | I could try to do a week earlier but would need to move around some other vacation plans. | 16:22 |
rosmaita | also, it's kind of late already | 16:22 |
jungleboyj | I am realizing that that date is coming up very quickly. | 16:22 |
jungleboyj | rosmaita: ++ | 16:22 |
smcginnis | That date worked well for everyone else. I think you should just stick to the plan and I can try to participate remotely as much as I can. | 16:22 |
rosmaita | will smcginnis be able to attend remotely at all? | 16:22 |
rosmaita | oh, ok | 16:23 |
jungleboyj | smcginnis: You will be West Coast? | 16:23 |
smcginnis | I'll be at an event that week, so I will have some distractions. But I can try to give my input inbetween things. | 16:23 |
smcginnis | Yeah, CA. | 16:23 |
jungleboyj | Ok. So you could participate for a bit in the morning and we could try to schedule things that you need to give input upon around that? | 16:23 |
jungleboyj | #link https://etherpad.openstack.org/p/cinder-train-mid-cycle-planning | 16:24 |

jungleboyj | We can change that. | 16:29 |
jungleboyj | BTW, I am hoping to have Zoom meetings by then which will help. | 16:30 |
jungleboyj | Ok, on to an even more contentious topic. | 16:30 |
jungleboyj | #topic Cinder PTG in Shanghai | 16:30 |
*** openstack changes topic to "Cinder PTG in Shanghai (Meeting topic: Cinder)" | 16:30 | |
jungleboyj | So, the request for projects to state their interest in the Shanghai PTG has gone out. | 16:31 |
jungleboyj | It sounds like a very limited number of people are planning to go to SH. | 16:31 |
jungleboyj | #link https://etherpad.openstack.org/p/cinder-shanghai-ptg-planning | 16:31 |
*** bobh has quit IRC | 16:31 | |
jungleboyj | I have started our PTG planning Etherpad to get an indication who plans to be there more than anything. | 16:31 |
LiangFang | Welcome to SH:) | 16:32 |
rosmaita | LiangFang: is that where you are? | 16:32 |
jungleboyj | I am pretty sure I am not going to be able to avoid being there. | 16:32 |
smcginnis | The ops meetup team recently did a Twitter poll to try to get feedback on number of attendees. I wonder if we should do something similar to try to get an idea of how many Cinder peeps will be there. | 16:32 |
LiangFang | rosmaita: yes, I'm in Shanghai | 16:32 |
jungleboyj | smcginnis: You are planning on going. Correct? | 16:32 |
smcginnis | I think so. | 16:33 |
jungleboyj | I could do that. Would bring public attention to this issue. | 16:33 |
jungleboyj | rosmaita: Is waiting to hear. | 16:33 |
jungleboyj | hemna: Is a no. | 16:33 |
jungleboyj | whoami-rajat: You are going to be there? | 16:33 |
rosmaita | hopefully will know sometime next week | 16:33 |
whoami-rajat | jungleboyj: hopefully, will be there. | 16:34 |
jungleboyj | Ok. So, that makes possibly 4 of us. | 16:34 |
jungleboyj | There are people that don't participate in this meeting who might want us to have the PTG though. | 16:35 |
jungleboyj | So the idea of a Twitter Poll isn't bad. | 16:35 |
rosmaita | also, i specifically asked to be sent to the PTG ... don't know if they'll be willing to send me if we don't have it! | 16:35 |
jungleboyj | Anyone here think we shouldn't do a PTG slot? | 16:36 |
rosmaita | i am pro-PTG | 16:36 |
jungleboyj | :-) Yeah, I think it would be bad for us to skip. | 16:36 |
jungleboyj | I think we would only need 2 days. | 16:36 |
jungleboyj | I would still do the Project update and Onboarding. | 16:37 |
jungleboyj | woojay: What did you ever hear about attending either of the events? :-) | 16:37 |
smcginnis | Those are now part of the PTG I think I heard. | 16:37 |
jungleboyj | Right. If we have the PTG we can do those. | 16:37 |
jungleboyj | So, that is another reason to do it. | 16:37 |
woojay | oh dang, I guess I better ask... 8-) probably PTG, I think. | 16:37 |
rosmaita | from the ML, it sounds like they're expecting a lot of demand for onboarding | 16:37 |
jungleboyj | woojay: Ok, awesome. Update the etherpad when you have a chance. | 16:38 |
jungleboyj | rosmaita: That would be nice. | 16:38 |
woojay | Sure. | 16:38 |
jungleboyj | Ok, so I am going to go forward with assuming that we will do it. | 16:38 |
jungleboyj | I will send out a poll and also a note to the mailing list and see what we get in the etherpad. | 16:39 |
jungleboyj | Anything else there? | 16:40 |
jungleboyj | Ok. Guess not. | 16:40 |
jungleboyj | So, last topic on the agenda | 16:40 |
jungleboyj | #topic Spec: Leverage compression hardware accelerator | 16:41 |
*** openstack changes topic to "Spec: Leverage compression hardware accelerator (Meeting topic: Cinder)" | 16:41 | |
jungleboyj | LiangFang: | 16:41 |
LiangFang | hi | 16:41 |
*** mattw4 has joined #openstack-meeting | 16:41 | |
jungleboyj | Hi. | 16:41 |
LiangFang | this is to leverage some hardware accelerator for image compression if such hw exist | 16:41 |
jungleboyj | Yep, remember discussing it at the PTG. | 16:42 |
LiangFang | yes, Lisa carry this topic there | 16:42 |
rosmaita | #link https://review.opendev.org/#/c/652275/ | 16:42 |
LiangFang | I get some comment from eric and yangxin, and rosmaita | 16:43 |
LiangFang | what should the format name be? gzip or gz? | 16:43 |
jungleboyj | Hmmm, thought I had read through this but guess not. I will do that today. | 16:44 |
*** iyamahat has joined #openstack-meeting | 16:44 | |
eharney | if it's always a gzipped raw image, .gz makes sense | 16:44 |
LiangFang | eharney: ok | 16:44 |
LiangFang | rosmaita said it should be a container format, not disk_format, i will take a look of it | 16:45 |
rosmaita | hopefully my explanation on the review makes sense | 16:45 |
jungleboyj | LiangFang: Is there any clarification you need from rosmaita right now? | 16:46 |
LiangFang | rosmaita, I will try to generate a spec-lite to glance, so the name of gz make sense to glance, right? | 16:47 |
jungleboyj | I feel like we had this discussion with Lisa at the PTG. | 16:48 |
rosmaita | i think so ... would it make sense to have a 'compressed' format, and then the consumer figures out what kind of compression was used? | 16:48 |
*** altlogbot_3 has joined #openstack-meeting | 16:49 | |
jungleboyj | rosmaita: Might be good to be able to handle multiple compression types in the future. | 16:49 |
LiangFang | do you mean not only support gzip, but also other format? | 16:49 |
eharney | it may depend on how many different implementations of this people want to create | 16:50 |
rosmaita | LiangFang: yes, we would only have to use gzip for your proposal, but the metadata in glance would say 'compressed' for the container_format | 16:50 |
rosmaita | then glance won't have to add a different identifier for every format | 16:50 |
jungleboyj | That makes sense. | 16:51 |
rosmaita | i believe most of them have a magic number in the header or something so you can tell what the compression format is? | 16:51 |
LiangFang | ok | 16:51 |
*** ricolin has quit IRC | 16:52 | |
jungleboyj | Anything else LiangFang | 16:53 |
LiangFang | another thing is: should we fail it if there's no hw accelerator exist when user try to use a gzipped image? | 16:53 |
eharney | no | 16:53 |
jungleboyj | LiangFang: No | 16:53 |
eharney | i'd also like to point out https://review.opendev.org/#/c/668943/ , which is a different take on image compression, maybe of interest here | 16:53 |
LiangFang | so we need to switch to software solution, right? | 16:54 |
*** _alastor1 has joined #openstack-meeting | 16:54 | |
*** altlogbot_3 has quit IRC | 16:54 | |
eharney | yes, it can just be ungzipped in software | 16:54 |
LiangFang | eharney: ok | 16:54 |
rosmaita | how about in the other direction? do we allow gzip on image create even if no hardware accelerator? | 16:55 |
jungleboyj | rosmaita: I would think so. | 16:55 |
eharney | we should, there's no reason to tie this feature to a hard requirement on hardware | 16:55 |
rosmaita | that was my thought, too | 16:55 |
jungleboyj | eharney: ++ | 16:56 |
LiangFang | eharney: ++ | 16:56 |
LiangFang | currently cpu is also very powerful | 16:57 |
jungleboyj | So, I think that covers that discussion. | 16:57 |
jungleboyj | Anything else we need to cover in the last 3 minutes? | 16:57 |
LiangFang | should be add the tool name such as qzip and gzip to cinder.filter? | 16:58 |
LiangFang | or let user to add by themself? | 16:58 |
LiangFang | add to this file, so these tool can be run in root wrapped | 16:58 |
jungleboyj | Uhm, I think it probably be added to the filter so it can be rootwrapped. | 16:58 |
LiangFang | ok | 16:59 |
jungleboyj | Ok. That is all the time we have for today. | 16:59 |
eharney | is this assuming that the input is always a block device? | 16:59 |
whoami-rajat | Thanks jungleboyj | 16:59 |
LiangFang | thanks | 16:59 |
jungleboyj | Please add your topics to the mid-cycle etherpad and update your attendance for the PTG. | 17:00 |
LiangFang | eharney: is it possible not a block device? | 17:00 |
jungleboyj | Thanks for joining the meeting! | 17:00 |
eharney | yes | 17:00 |
smcginnis | Should probably continue in the cinder channel. | 17:00 |
jungleboyj | smcginnis: ++ | 17:00 |
jungleboyj | #endmeeting | 17:00 |

rledisez | mattoliverau: yep :) | 21:03 |
*** altlogbot_2 has joined #openstack-meeting | 21:03 | |
timburke | so first, a warm welcome back to rledisez :-) | 21:04 |
clayg | rledisez: I was just thinking about the class Canadian children's song "Donkey Riding" - You're all assimilated to canadian culture now Ay? | 21:04 |
clayg | *classic Canadian... | 21:04 |
rledisez | clayg: i'm trying to learn *their* french first, i'll check the music culture after ;) | 21:04 |
clayg | apparently i've also been doing some object oriented programming 😬 | 21:04 |
mattoliverau | lol | 21:05 |
timburke | glad to have you back rledisez -- hopefully i'll even get us merging code to losf again ;-) | 21:05 |
clayg | yeah mattoliverau know about "their English" pleanty well | 21:05 |
timburke | speaking of... updates! | 21:05 |
mattoliverau | lol, still learning my american english tho :P | 21:05 |
timburke | #topic py3 | 21:06 |
*** openstack changes topic to "py3 (Meeting topic: swift)" | 21:06 | |
timburke | all of the patches patches to get us to a voting py2-tests-against-py3-services are approved! | 21:06 |
mattoliverau | rledisez: welcome to a commonwealth country (like Australia). :P | 21:06 |
mattoliverau | \o/ | 21:06 |
timburke | now it's just a matter of getting them through the gate ;-) | 21:07 |
kota_ | nice | 21:07 |
mattoliverau | and then a release! | 21:07 |
timburke | once those are in, i'll rebase the authors/changelog patch and update it for whatever else has landed | 21:07 |

*** altlogbot_2 has quit IRC | 21:08 | |
timburke | if you know of anything else that should absolutely be in this release, let me know soon | 21:08 |
timburke | though worst case, we can always have more releases :) | 21:09 |
kota_ | :/ | 21:09 |
timburke | after that... i saw zaitcev's been starting to review the func test changes | 21:09 |
timburke | thank you zaitcev! | 21:09 |
timburke | that's about it for py3 | 21:10 |

*** openstack changes topic to "lots of small files (Meeting topic: swift)" | 21:10 | |
clayg | tdasilva: I think we can get in cache shard ranges yeah? | 21:10 |
clayg | timburke: what about the reconciler+sharding bug? worth holding the release? | 21:11 |
tdasilva | clayg: i think so, i left a couple of comments for timburke but they are mostly nits | 21:11 |
timburke | clayg, i'm not sure. maybe? | 21:11 |
rledisez | about losf, alecuyer told me about this patch to add unit tests to a core component of losf (the file-like interface) | 21:12 |
rledisez | #link https://review.opendev.org/#/c/666378/ | 21:12 |
patchbot | patch 666378 - swift (feature/losf) - Add tests for vfile.py - 4 patch sets | 21:12 |
timburke | yes! and i think i found the source of the gate trouble on feature/losf | 21:12 |
timburke | #link https://review.opendev.org/#/c/670139/ | 21:12 |
patchbot | patch 670139 - swift (feature/losf) - Back out urllib3 requirement - 1 patch set | 21:12 |
kota_ | oic, I should go to look at the patch. | 21:12 |
kota_ | nice work timburke | 21:12 |
timburke | i think those were the main points of progress there. assuming that my urllib3 change is sufficient to get the gate happy again, i'll get to work on getting a fresh merge from master | 21:13 |
kota_ | i'll add +A when the gate passed. | 21:14 |
timburke | which will also involve | 21:14 |
timburke | #link https://review.opendev.org/#/c/664424/ | 21:14 |
patchbot | patch 664424 - swift (feature/losf) - Get new unit tests running under py3 - 2 patch sets | 21:14 |
kota_ | don't we have to black list any viersion? | 21:14 |
timburke | kota_, i would've thought that requests should do that, since they've got the dep. maybe we need to blacklist some version(s) of requests, though? | 21:15 |
kota_ | e.g. != 1.25.x | 21:15 |
timburke | since we don't actually use urllib3 directly, i'd rather not add it to our requirements if we don't have to... | 21:15 |
timburke | in fact, i'd kind of like to get rid of requests. we only use it for s3token iirc | 21:16 |
kota_ | oic. the dependency should be resolved at requests. make sense. | 21:16 |
timburke | does anybody have anything else on losf? | 21:17 |
*** altlogbot_3 has joined #openstack-meeting | 21:18 | |
timburke | #topic sharding | 21:18 |
*** openstack changes topic to "sharding (Meeting topic: swift)" | 21:18 | |
timburke | i looked at the doc -- seems promising! and i think i can see how at least some parts of this could be broken out so we could have small, digestible pieces to review | 21:19 |
timburke | i know i'm super excited about the idea of fully-automated sharding | 21:20 |
mattoliverau | I saw that, thanks Tim | 21:20 |
timburke | but... we might have a few bugs we want to squash before turning it on | 21:20 |
mattoliverau | I still want to write a probe test to test the potential edgecase. but haven't done it yet. | 21:20 |
mattoliverau | yeah | 21:21 |
timburke | in particular, i'm thinking about https://bugs.launchpad.net/swift/+bug/1836082 | 21:21 |
openstack | Launchpad bug 1836082 in OpenStack Object Storage (swift) "Reconciler-enqueuing needs to be shard-aware" [High,Confirmed] | 21:21 |
timburke | and to a lesser degree, https://bugs.launchpad.net/swift/+bug/1834097 | 21:21 |
clayg | such a great bug | 21:21 |
openstack | Launchpad bug 1834097 in OpenStack Object Storage (swift) "container-sharder has no latch when reporting stats" [Undecided,New] | 21:21 |
clayg | oh yeah... classic | 21:21 |
timburke | but of course, the level of automation would be configurable, so those shouldn't really be thought of as blockers to mattoliverau's wonderful work | 21:22 |
timburke | just wanted to mention them since we're talking about sharding anyway | 21:22 |
*** altlogbot_3 has quit IRC | 21:22 | |
mattoliverau | fair enough. Yeah. I want to be sure we're ready when we recommend/support autp sharding | 21:22 |
mattoliverau | but want to get there, so getting the ball rolling ;) | 21:23 |

diablo_rojo_phon | Yes please :) | 21:25 |
clayg | where in the world is tdasilva come ptg time? | 21:25 |
clayg | I wanna go! when is it... | 21:25 |
timburke | we've got some time before we need to give them an answer, but i thought i should start prodding people now to figure out whether they're going ;-) | 21:25 |
*** zhubx has quit IRC | 21:25 | |
diablo_rojo_phon | By the start of August ideally. | 21:25 |
timburke | summit's nov. 4-6; ptg's nov. 6-8 | 21:26 |
tdasilva | ¯\_(ツ)_/¯ | 21:26 |
timburke | and if you're like me, you'll need a visa to go | 21:26 |

clayg | timburke: a passport isn't good enough!? | 21:27 |
rledisez | timburke: maybe an etherpad as usual? it's not confirmed yet but alecuyer and I should be present | 21:27 |
mattoliverau | yeah, I think I'll need a visa too. | 21:27 |
timburke | #link https://openstackfoundation.formstack.com/forms/visa_form_shanghai_summit | 21:27 |
timburke | will probably both be useful | 21:27 |
kota_ | i'm planning to get there. got approved by a verbal promise so far | 21:27 |
mattoliverau | still waiting to hear back from work on who's going. | 21:27 |
timburke | kota_, \o/ | 21:27 |
timburke | i'm planning on going too | 21:27 |
diablo_rojo_phon | I highly recommend using a visa service especially for those that don't live close to a Chinese embassy. | 21:27 |
kota_ | oh, VISA? I think Japanese passport is the strongest in the world. | 21:28 |
timburke | rledisez, yeah, i'll make an etherpad by next week | 21:28 |

kota_ | one thing, did anyone buy a ticket for the Summit+PTG? | 21:29 |

kota_ | including reception or not. | 21:30 |
tdasilva | i wonder how easy it is (visa wise) to bring spouse + family | 21:30 |
diablo_rojo_phon | kota_: to my understanding VIP just includes a VIP party? Im told it's a common thing for events in China. | 21:30 |
kota_ | either is fine to me so far. just I want a same ticket with other contributors. | 21:30 |
rledisez | sould we expect a voucher this time for the summit+ptg ticket? | 21:31 |
kota_ | rledisez: both include summit+ptg, my understanding. | 21:31 |
kota_ | both -> every kind of ticket, i mean. | 21:31 |
diablo_rojo_phon | rledisez: you mean like a discount? | 21:32 |
kota_ | oh | 21:32 |
timburke | extra 200 for a party?? whoa | 21:32 |
rledisez | I mean, before buyng the summit+ptg ticket, should I wait for a voucher/discount (we always had one previously if we attended PTG or being a ATC, …) | 21:33 |
diablo_rojo_phon | timburke: yeah I guess this is a normal thing? Other conferences held in China have done the same. | 21:33 |
timburke | oh, but yeah -- i expect there will be a discount code again. so it's a good thing i haven't done anything yet :-) | 21:33 |
clayg | procrastinate ftw | 21:33 |
timburke | diablo_rojo_phon, i believe you, just surprising to me :-) | 21:34 |
diablo_rojo_phon | rledisez: there will likely be discounts for contributors but the detail of how much havent been decided yet. The plan is to have that by the end of August I think? Maybe the start? I can't remember. | 21:34 |
diablo_rojo_phon | timburke: it surprised me too if that's any consolation. | 21:34 |
rledisez | diablo_rojo_phon: ok, thx, i'll wait a bit before buying then | 21:34 |
kota_ | diablo_rojo_phon: good info. I should wait the info for now. | 21:34 |
timburke | diablo_rojo_phon, thanks! you've saved me from trying to dig through my email mid-meeting | 21:34 |
timburke | that's all i really wanted to bring up | 21:35 |
diablo_rojo_phon | timburke: one of my ping words came up and so I started paying attention and figured I'd spread the knowledge since I'm here :) | 21:35 |

diablo_rojo_phon | When might you be interested in migrating? :) | 21:36 |
timburke | diablo_rojo_phon, ok, maybe i meant "CAN wait for the performance optimizations" :P | 21:37 |
kota_ | one thing, I'll join an OpenStack event in Japan. And there, I'll be a mentor for OpenStack Upstream Institute. If anyone keeps good hanging fruits for newbees, please let me know anytime. | 21:38 |
diablo_rojo_phon | Lol. Fair. I'll come prod y'all when we make some changes. | 21:38 |
timburke | oh, cool! that's great kota_ | 21:39 |
timburke | https://bugs.launchpad.net/swift/+bug/1835324 might be a good one | 21:39 |
openstack | Launchpad bug 1835324 in OpenStack Object Storage (swift) "Internal client's delete_object always logs 499 for 404s" [Low,Confirmed] | 21:39 |

timburke | we should probably try to curate https://bugs.launchpad.net/swift/+bugs?field.tag=low-hanging-fruit a bit | 21:39 |
kota_ | looks fine, that confirmed but lower priority bug. thanks timburke | 21:39 |
*** boxiang has quit IRC | 21:40 | |
kota_ | okay. | 21:40 |
mattoliverau | kota_: nice! | 21:40 |
timburke | oh, i've got a question for people: how do you usually deploy the reconciler? is it running on every node? just one node? some subset of nodes? | 21:41 |
timburke | iirc we do it on every container node... and it turns out that it can be kinda terrible that way | 21:42 |
timburke | see also: https://bugs.launchpad.net/swift/+bug/1836111 | 21:42 |
openstack | Launchpad bug 1836111 in OpenStack Object Storage (swift) "container-reconciler needs to scale better" [Undecided,New] | 21:42 |
kota_ | iirc, one node. or no-reconciler if customer is using only one policy. | 21:42 |
rledisez | timburke: we run it on every container node | 21:43 |
timburke | which clayg ('cause he's a smart guy) has a patch for at https://review.opendev.org/#/c/103779/ | 21:43 |
patchbot | patch 103779 - swift - Add support for multiple container-reconciler - 9 patch sets | 21:43 |
clayg | that was forever ago, i *used* to be smart | 21:43 |
tdasilva | 2014?? | 21:44 |
clayg | basically right after we finished storage policies | 21:44 |
*** boxiang has joined #openstack-meeting | 21:44 | |
timburke | just a heads-up, as much as anything | 21:44 |
clayg | somehow i'ver never seen much work in the .misplaced_objects queue 🤷♂️ | 21:44 |
clayg | it's possible I've not spent much time looking for it | 21:44 |
*** zhubx has quit IRC | 21:45 | |
clayg | I have a story to add more monitoring to that queue - but we don't really keep tabs on it ATM | 21:45 |
zaitcev | I run reconciler on every node, which is probably wasteful and bad but my cluster is too small to tell. | 21:45 |
zaitcev | Especially in view of that patch set. | 21:46 |
clayg | ok, so sounds like everyone is already putting running it the way we expected - and we just need to go ahead and add the process/processes? | 21:46 |
clayg | or maybe we should try to unify it with the expirer re-work and merge all that stuff! | 21:46 |
zaitcev | Kazuhiro's legacy, huh | 21:46 |
clayg | move the reconciler config into the container-server config - the whole nine | 21:46 |
rledisez | clayg: +1 | 21:47 |
clayg | something to think about 🤔 | 21:47 |
*** irclogbot_2 has joined #openstack-meeting | 21:48 | |
tdasilva | probably makes sense to move to the new model | 21:48 |
timburke | anything else to bring up? | 21:50 |
clayg | rledisez: oh, i was thinking about the layout for the queues we where talking about - how to divide it up ring/part/job/obj where the containers were <ring-part> and man... I think that's pretty solid layout | 21:50 |
clayg | I think that's what we agreed on 🤔 | 21:50 |
*** artom has quit IRC | 21:50 | |
clayg | Anyway the reason I like it is cause when processing it *really* starts to look like "walking the partition space" but using container listing instead of filesystem listdirs! | 21:51 |
rledisez | clayg: yep, I thought of it also and I like it. I started to work on it but had to stop to move. i'll continue next week | 21:52 |
*** irclogbot_2 has quit IRC | 21:52 | |
timburke | i kinda wonder if it'll need a new partition-power-like thing though -- something to make that probe test time less terrible | 21:53 |
clayg | oh it's .task-<ring>-<type> accounts and <partition> container - even better! | 21:53 |
clayg | @timburke it's a pretty simple optimization to do a account level listing and only list part containers that are assigned to you (and also exist) | 21:54 |
rledisez | and the object start with the timestamp of the scheduled task, so we can just iterate the container listing. no more need for time bucket and stuff… we have sharding! | 21:54 |
clayg | the problem is it's an optimization that only makes sense in DEV - in prod you'll have the parts - so we could maybe like "if you get a 404 trying to container list go ahead and account list" | 21:54 |
clayg | @rledisez yeah like if you have 10T objects in a 2^20 🤔 | 21:56 |
clayg | we were recently contemplating our first part power increase - which will have the same problem in the queue as it does on disk... | 21:57 |
clayg | maybe we could encode the epoch into the queue or something so we can recognize a "this object isn't in this part anymore" from "this object isn't in this cluster anymore" | 21:58 |
rledisez | hum… moving entries between containers… (i don't like that) | 21:58 |
timburke | all right, we're coming up on time. i propose we move the task queue discussion to #openstack-swift :-) | 21:58 |
clayg | task queue! | 21:58 |
timburke | thank you all for coming, and thank you for working on swift! | 21:59 |
