zhiyuanYipei, how about the new l3 networking model, any update?01:34
song__agree with it.01:34
Yipeienable external network with transparent local router is ongoing, it will be complete in a week or two01:35
Yipeinext part is introducing routed network, and then is the floatingip creation01:37
zhiyuannot quite get the first part, what does "transparent local router" mean?01:37
Yipeicreate a external network as well as creating a local router for the external network01:39
zhiyuanyou mean creating the local router when the external network is created?01:40
zhiyuanbut external network may be created before central router01:42
*** xuzhuang has quit IRC01:44
Yipeiyes, i mean the router creation includes local and central router creation, "the local router" means "a non-distributed router" which is only attached to one external network01:44
*** iyamahat has joined #openstack-meeting01:45
zhiyuancreate central router automatically?01:45
*** xuzhuang has joined #openstack-meeting01:45
Yipeiyes, and the router is transparent to users01:46
*** ekcs has quit IRC01:46
zhiyuanhmm, this interaction is different from the normal one. normally user (1) create external network (2) create router (3) set router gateway01:47
*** jamesmcarthur has joined #openstack-meeting01:48
*** jamesmcarthur has quit IRC01:48
zhangchizhiyuan  any more infos about the task "Driver-based implementation of Trunk the current implementaion is plugin-based"?01:51
*** felipemonteiro__ has joined #openstack-meeting01:51
Yipeii think there are two logic: (1) create a routed network(including real external networks); (2) create a distributed router; (3) set router gateway; the second one is when creating real external networks, a router is created and attached to the external network.01:52
zhiyuanzhangchi, our current implementation of trunk is to rewrite the whole plugin, but neutron expost trunk driver so I think we can write a new tricircle driver for trunk plugin01:53
Yipeiwhen setting the gateway of routed network to the distributed router, the local routers and the distributed router are connected via bridge network01:53
zhiyuanso when will local router be created? when setting gateway or when creating central router?01:57
zhangchiok I read it first  kind of you :)01:57
Yipeiall the three steps are done when creating a external network01:58
zhiyuanso we don't provide user the chance to create central router?01:58
*** yamahata has joined #openstack-meeting01:58
Yipeiyes, they only need to create one distributed router01:59
zhiyuandoes user need to set external network gateway as the distributed router?02:00
Yipeithey only need to set the gateway of the routed network as the distributed router02:02
zhiyuanoh i see, so the distributed router is what I mean "central router"02:02
*** gongysh has joined #openstack-meeting02:03
Yipeioh, i see, not the router in central neutron02:03
zhiyuanI think time's up, let's discuss offline02:04
zhiyuanthanks for attending the meeting02:05

oneswigTwo forum topics proposed at present11:03
oneswig#link etherpad for forum
oneswigThere was a good deal of interest in blazar's model of reservations at the PTG. I wonder if that would make a good subject.11:04

*** zhangchi has joined #openstack-meeting11:05
qwebirc54714hey there11:05
oneswigmartial_: do you remember the date for submissions?11:05
qwebirc54714CHristian Kniep here11:05
oneswigHi Christian - thanks for coming along11:06
oneswigand at short notice too11:06
qwebirc54714are we going to stick with IRC?11:06
oneswigI think so - all the meetings are logged and I often get messages from people who read the logs afterwards11:06
oneswigIt's a low-intensity form of meeting...11:07
*** yamamoto has joined #openstack-meeting11:07
oneswigShall we get started?11:07
oneswig#topic Docker and HPC environments11:07
*** openstack changes topic to "Docker and HPC environments (Meeting topic: scientific-sig)"11:07
martial_Which workshop?11:07
oneswigSo I met Christian and martial_ met Christine around the same time11:07
*** Tom-Tom has quit IRC11:08
oneswigmartial_: Vancouver forum11:08
*** Tom-Tom has joined #openstack-meeting11:09
oneswig#link Christian's presentation on Docker and HPC
qwebirc54714I am sorry guys; I was not aware that it will be textual. Am I supposed to walk you trough the presentation now?11:10
oneswigQ&A works well, is that OK?11:10
qwebirc54714ok, cool... I only have like 10min as I have to jump on something that came up.11:10
*** fmccrthy has quit IRC11:11
oneswigChristian - there's two sides to this integration I think.  Stuff that HPC people want to see and stuff that Docker does that HPC doesn't want to see.  Is that true?11:11
*** fmccrthy has joined #openstack-meeting11:11
qwebirc54714kind of, yes. Coming from the cloudy side of things; docker fancies being host-agnostic, while HPC/AI needs to be host-specific in order to mount in certain shared file-systems and devices11:12
oneswigCan you talk about what your projects in Docker are aiming to improve?11:13
*** Tom-Tom has quit IRC11:13
oneswigfor HPC use cases that is11:13
qwebirc54714furthermore, a user has to be honored no matter what; thus pinning the UID:GID for a given container according to the user executing the docker run is a must11:13
qwebirc54714page 31 explains what we need to do in order to fix it.11:14
qwebirc54714the improvement would be reproducibility, portability (this time for real) and (my favorite) performance-optimization since the container file-system only has to support the solver and not all the services around it (syslog, slurmd, ...)11:15
oneswigHow do you see workload schedulers working - slurmd talks to dockerd, or something more streamlined?11:15
*** VW has joined #openstack-meeting11:15
martial_Oneswig: "Deadline for proposing Forum topics. Scheduling committee meeting to make draft agenda" was April 1511:15
oneswigah, oops...11:15
qwebirc54714first iteration: the batch scripts fires up the container, either `create` in a prolog or `run` in the script. Later on we can have a look at more optimised solutions11:16
qwebirc54714from my POV: page 25 in the end11:16
qwebirc54714the workload schedulers schedule and let the engine execute the binary (within a container of course)11:17
oneswigChristian - there was reference in the feedback at HPCAC to a desire to have a process group lineage, which dockerd doesn't provide.  Is that something you've seen much?11:17
qwebirc54714process group lineage... can you elaborate a bit - not sure I understand11:17
oneswigparent, child, process tree11:18
oneswigI think that was the issue11:18
*** zhangchi has quit IRC11:19
oneswigThe bash script you mentioned doesn't have a descendent which is the active workload11:19
qwebirc54714yeah, ok... I guess you are hinting at MPI wire-up. I did it by spawning orted using a fake ssh client so far11:19
oneswigI'm aware you're tight for time.  Have you got a link to your work?11:20
qwebirc54714that would be something to work on, I reckon that the docker-engine could include a PMIx server and we are all fine - but that is a long way to iterate towards11:20
qwebirc54714but the README needs an update with an example.... :/11:20
oneswigThanks.  You think this kind of HPC-oriented runtime configuration is a way off - any idea how far?11:21
qwebirc54714I did a hack last week, forcing the changes upon the docker-engine11:22
*** liuzz_ has joined #openstack-meeting11:22
qwebirc54714but that is far from being the solutions; it is a hack, but that is the functionality I would like to see11:23
*** liuzz has quit IRC11:23
oneswigThis is for enabling GPU passthrough specifically?11:23
qwebirc54714you can map in any device, so IB/OPA should work as well - didn't have access to an IB system11:24
qwebirc54714also default mounts for a given cluster, based on how it is mounted on the host11:25
qwebirc54714like /A/home vs /B/home has to be mounted to /home11:25
oneswigSeems useful to me... There were some interesting points around IB and network isolation.11:26
oneswigSome people do not co-locate running workloads on the same node but others do.11:26
oneswigBut those that do share an IB resource today and seem happy with it.11:26
oneswigIs anything more necessary in terms of isolation?11:27
qwebirc54714it is a start and I won't go into the weeds of site-specific solutions. :)11:27
qwebirc54714there is no silver bullet for HPC, not even a bronce one. :)11:27
*** VW has quit IRC11:27
oneswigIs this use case getting much interest within Docker inc?11:28
qwebirc54714I rather provide the building blocks and a flexible solution, so that sites and vendors can tailor it to their needs11:28
qwebirc54714The GPU use-case might carry it over the finish line. Much more buzz then in HPC land11:28
oneswigCertainly seems that way with AI11:29
qwebirc54714but as I showed in page26ff: the GPU use-case will end up as a tightly coupled, distributed workload relying on RDMA and shared filesystems.11:29
qwebirc54714et voila - you have your HPC job covered right there11:29
qwebirc54714and I do not care how we get over the finish line.11:29
oneswigLooking ahead, do you see the OCI components changing things, around runC for example?11:30
qwebirc547145min more, then I have to drop11:30
qwebirc54714there was a RDMA namespace PR a couple of weeks ago11:30
*** liuzz_ has quit IRC11:31
*** chyka has joined #openstack-meeting11:31
*** liuzz has joined #openstack-meeting11:31
qwebirc54714runC has almost everything we need to make it work; it is the stack above the needs to be enabled. the engine and containerd11:31
oneswigI think the one you linked to was RDMA cgroups rather than a namespace - isn't that more about resource management?11:31
*** b1airo has joined #openstack-meeting11:32
qwebirc54714Haven't look at it but my understanding is that it's both.11:32
oneswigI saw this - assume you're well familiar with it:
b1airoo/ hello all, sorry for being late! Now what's the most annoying question I can ask that has already been discussed...?11:33
qwebirc54714to me, user-land container are just a drop-in replacement like singularity and shifter that will work with existing workloads.11:33
oneswigHi b1airo11:33
*** lamt has quit IRC11:33
oneswig#chair martial_ b1airo11:33
openstackCurrent chairs: b1airo martial_ oneswig11:33
*** lamt has joined #openstack-meeting11:33
*** lamt is now known as Guest6206411:34
qwebirc54714it's about the abstraction/orchestration above and the streamlining of the execution no matter what orchestration you are using.11:34
oneswigqwebirc54714: the drop-in bit is quite appealing.  Perhaps the user portability between environments is maximised then11:34
qwebirc54714I know it is appealing but you need to be OCI compliant in order to hook into kubernetes and swarm (and the future once).11:35
*** chyka has quit IRC11:35
qwebirc54714shifter, singularity and alike (IMHO) can not be OCI compliant as they would need to become runC + a bit of containerd11:35
qwebirc54714ok guys, have to drop out. sorry for being in a hurry11:36
oneswigOK thanks Christian.11:36
*** qwebirc54714 has quit IRC11:36
martial_Thanks Christian11:37
martial_(too slow on my phone keyboard)11:37
oneswigIt's an interesting question on oci compliance and kubernetes integration11:37
martial_Is Christine still with us?11:37
oneswigI'm not sure they are aiming for that but I do think the commonality of codebase helps with maintainability11:38
davehollanddo users typically ask for "I want to run containers" or "I want something with OCI compliance"? (the former, IME)11:38
priteauI suppose they generally want to run containers [that they already run elsewhere on a non-HPC environment]11:39
oneswigI think we have the same - the advantages of a familiar development environment.  I don't think our users are onto defining their applications through kuberenets11:39
verdurinI think the question is whether, if you use k8s, that community will help you if you're not using something OCI-compliant11:40
davehollandoneswig: we have a few brave adventurers putting kubespray on top of openstack11:40
oneswigdaveholland: we've used that, it's actually pretty easy to get something going.  There's quite a bit of invention going on around integrating the two11:40
oneswig(as in, kuberenetes and openstack)11:40
davehollandbut, it's "just" another bit of learning curve :)11:41
oneswigbut mostly we like using Magnum, when we can11:41
*** jonmills has joined #openstack-meeting11:41
oneswigdaveholland: and I'm sure they aren't doing it for the sysadmin skills, this is just in the way of their goal11:41
davehollandoneswig: oh exactly, we (sysadmins) are only just on top of openstack admin, before we think about providing container orchestration as-a-service11:42
oneswigThe HPC container landscape is pretty interesting right now and OpenStack infrastructure sits especially well beneath it all11:43
oneswigOK, shall we move on?11:43
oneswigany final thoughts?11:43
oneswigIt might be interesting to invite someone from one of the dedicated HPC container projects along for another point of view11:44
martial_I need to check if both Christine and Christian are going to be at DockerCon11:45

martial_The other one was why we are doing it and what that means with a little bit of how11:48
b1airoSounds good martial_11:49

b1airoI'm not sure where I'll be yet (Europe or US)11:49

oneswigIs anyone here going to ISC?11:50
*** caowei has quit IRC11:51
verdurinoneswig: considering it11:51
b1airoI put the two Forum session suggestions that came via the SIG - GPUs and Preemptible Instances - in to the Forum site (albeit a day late)11:51
b1airo(for Vancouver)11:51
oneswigAlas I am not planning to go - but I'll be at HPC Knowledge Partnership in Barcelona the week before.11:51
oneswigb1airo: thanks!  I'd not been keeping on top of that at all.11:51
oneswigGlad someone is...11:51
martial_I can add you if you want Blair11:51
*** liyi has quit IRC11:52
verdurinoneswig: have you a link for the Barcelona event?11:52
davehollandboth sessions are of interest to us but particularly preemptible11:52
priteauAbout the Forum, the Blazar has submitted a topic to discuss requirements for resource reservation across OpenStack11:52
priteauthe Blazar *team*11:52
verdurin(don't worry, found it)11:53
b1airooneswig: yeah I got invited for the Barcelona thing but can't go unfortunately. Alas, would have loved to return11:53
oneswigI don't think the programme's up yet but it's here:
oneswigpriteau: excellent - was hoping it would get covered given the interest in Dublin11:53
priteauIt still has to be selected of course11:54
priteauIIRC at the last summit we merged with another topic11:54
b1airopriteau: i.e. not just Nova resources?11:54
*** armax has quit IRC11:54
priteaub1airo: indeed, we would like to integrate with other projects as well. Reserving floating IPs from Neutron is a use case for NFV.11:56
oneswigI think Bob Budden also wanted a mention of the workshop on Container-based systems for Big data, Distributed and Parallel computing - in Turin in August -
oneswigI assume that means he's going!11:57
oneswigpriteau: if you'll be in Vancouver for this session, you should begin it with the demo of Chameleon's system. It's compelling.11:58
b1airoLove a call for participation that starts with, "Nowadays..." :-)11:58
*** YanXing_an has joined #openstack-meeting11:58
*** rbowen has joined #openstack-meeting11:58
b1airo+1 to that suggestion11:59

*** yamamoto has quit IRC15:13
dpertinprmachan: this is not scheduled now but you can add a new item here:15:14
dpertinAre you refering to the FEMDC F2F on Thursday?15:14
prmachanI have requested an additional session to cover following the onle listed above and room numbet will be smae except seesion 2 of edge will cover cross project co-ordination15:15
prmachanand I believe Adrian and MPP team is very improtant to to present enos to test different edge cloud uses cases15:16
dpertinprmachan: can you add an item regarding enos presentation/update in the brainstorming pad? Since we have two sessions we might have time for that15:17
prmachan#plus ONAP & OPNFVedge group are also requested to join the discussions to get blueprints discussions on minimizing overlaps15:17

dpertinFrom our side, we are still waiting for the HotEdge notification15:26
dpertinGood news? Bad news? Let's keep our fingers crossed ¯\_(ツ)_/¯15:27
dpertinNow, regarding the gap analysis...15:27
dpertinThanks to csatari who organized two meetings, we have started to review the wiki page he created following the discussions at the PTG15:28
*** felipemonteiro_ has joined #openstack-meeting15:28

*** rajinir has joined #openstack-meeting15:29
*** felipemonteiro__ has joined #openstack-meeting15:29
dpertinA third meeting will be scheduled soon if you want to be part of the review process15:29
dpertinFollowing this analysis, we are some people at Inria discussing about how to extend OpenStack to provide the "collaboration between edge cloud instances" feature as defined in the wiki page made by csatari15:30
dpertin"cloud instance" refers to independent openstack instance like the ones provided by the OpenStack region mechanism15:31
*** annabelleB has quit IRC15:31
*** felipemonteiro has quit IRC15:31
dpertinFor that, we started to list few simple operations like: booting a VM on Site A, using an image from Site B15:31
prmachanreviewed it yesterday and  which profile Smalla or Medium you use here in MPP/enos?15:31
rcherrueauprmachan: MPP?15:32
dpertinFrom this list, we identified that cross-site operations can be either inter-service/project (e.g. my previous example involves nova from site A and glance from site B) or intra-service/project (e.g. list VMs on site A and site B uses nova from site A and nova from site B)15:32
*** felipemonteiro_ has quit IRC15:33
prmachanSo what they call Minimum Viable Solution(MVS) , how enos will use it and will conpute node or sites focus on multi core Massive Parallel Processing?15:33
prmachanI see15:33
dpertinThis has an impact regarding the communications (apis, bus, databases) involved during a collaborative operation, which is critical regarding our analysis15:33
*** zz9pzza has quit IRC15:33
prmachanSounds perfect, question is what do I make of Original site vs. remote site therin , des it refer to Central and Edge sites/nodes?15:35
*** andreas_s has quit IRC15:36
*** goldenfri has joined #openstack-meeting15:36
prmachanso when you say Inter and Intra does refer to edge to edge or edge to central?15:36
dpertinFor instance: for the inter-service example, nova from A asks an image to the glance from B, and glance can find the information in the database of B - however for the intra-service operations, nova in B might look for information only available in the database of A15:36
*** goldenfri has left #openstack-meeting15:36
dpertinprmachan: I would more segment operations between mono-site operations (either local or remote) and collaborative operations15:37
prmachanAre we tallking peer to peer openstack operations here independent of hierarachy of central and edge clouds?15:37
prmachanNow I undertans , thanks for expalinig mono-site15:38
dpertincollaborative operations = operations that involve multiple sites - it can be based on P2P mechanism15:38
*** gyee has joined #openstack-meeting15:39
rcherrueauprmachan: regarding EnOS, there is nothing settled. EnOS helps us to deploy several OpenStack configuration for performance analyses. At some point, EnOS should be able to deploy small or medium edge nodes (to be honest, I am not sure to understand what small and medium refer to, in this context)15:39
dpertinOur questions now is should we implement things at the API level, at the low-level (DB,bus) or in-between15:39
prmachanThose are more hardware profiles and can be atbest described through topology templates for hardware15:40
*** felipemonteiro__ has quit IRC15:40
*** felipemonteiro__ has joined #openstack-meeting15:40
dpertinFurthermore, such question were probably met by the people who designed nova cells and/or projects like tricircle/trio2o, so having a look at those projects is probably a good way to fuel our analysis15:40
dpertinMaybe we should go forward and come back to it later, or on the pad15:41
dpertin#topic ongoing-topic-cockroach15:41
*** openstack changes topic to "ongoing-topic-cockroach (Meeting topic: fog-edge-massively-distributed-clouds)"15:41
dpertinmarie_: rcherrueau: the floor is yours ;)15:41
rcherrueauprmachan: Yes you are right, you can imagine a fancy DSL to describe your topology and it could be could to get such DSL in EnOS. But, this is not in the roadmap15:42
marie_We redefined a better test plan last week15:42
*** hamdyk has joined #openstack-meeting15:42
marie_The one written in the pad15:43
*** hongbin_ has joined #openstack-meeting15:43
marie_The main difference is we are now testing the influence of regions separated by a high latency, but the regions itself have several nodes that have no latency between them15:44
dpertinmarie_: nice, is your test plan described in the performance team documentation?15:44
marie_*we are also testing15:44
marie_not yet, I have to rewrite that also, since the test plan has changed15:44
msimoninWhat is "Number of nodes" ?15:45
*** felipemonteiro__ has quit IRC15:45
rcherrueauNumber of nodes in the database cluster15:45
*** tpsilva has joined #openstack-meeting15:45
msimoninwhat is the quorum size ?15:46
dpertinmarie_: any results from this test plan?15:46
marie_it's the default size15:46
rcherrueaumsimonin: 3 for cockroach (default)15:46
prmachan#is there a link to follow the test plan?15:46
marie_we have -mostly- the results for the two first goals15:46
msimoninrcherrueau: thanks15:46
dpertinmarie_: ok thanks (regarding the perf wg)15:47
marie_and we are actively working on the third part of the experiments15:47
msimonin1*3 means 1 site with 3 db nodes ?15:48
*** chyka has joined #openstack-meeting15:48
marie_and no latency between them15:48
dpertinmarie_: have you tried the last new version of cockroach?15:49
dpertinI heard they made improvements regarding the performance15:49
marie_Yep, we patched the framework to use Cockroach 215:50
dpertinanything else from your side?15:50
marie_I don't think so15:51
rcherrueauyes, I add something lines 504-51215:51
rcherrueauSome advocate keystone is write once, multiple multiple multiple ... reads at database level15:51
marie_oh, right, thanks !15:51
*** munimehan has joined #openstack-meeting15:52
rcherrueauAnd it could be cool to know the real ratio because this may have an impact when you choose a replication strategy or another15:52
rcherrueauso here are some ratio we compute with the tool marie_ developed.15:52
msimoningreat ! :)15:52
dpertinIs it computed from rally tests?15:52
*** xgerman_ has quit IRC15:53
*** annabelleB has joined #openstack-meeting15:53
*** xgerman_ has joined #openstack-meeting15:53
rcherrueauNote that the ratio of reads/writes may be a little more in favor of reads, than what it is presented here because, the following also take into account the creation/deletion of rally context that performs INSERT and DELETE.15:53
rcherrueaudpertin: yes from rally scenarios15:53

geguileothe spec looked good to me, and I think eharney liked the idea16:16
*** raildo has quit IRC16:16
arnewiebalckthere is no rush from my side, we can give it another week and rediscuss next week when more people had a chance to have a look?16:16
smcginnisI know other storage devices have a trash concept. I wonder if we do this if we should make sure it is not RBD specific.16:16
*** dpertin has quit IRC16:16
smcginnisOr maybe that doesn't matter here. I need to look it over yet.16:17
jungleboyjsmcginnis:  Good thought.16:17
arnewiebalckIIRC the trash/restore idea was not very popular16:17
*** masayukig has joined #openstack-meeting16:17
arnewiebalckalthough the trash is made for this16:17
arnewiebalck(and we would have loved to have this this week actually :-/)16:17
smcginnisGlad to see you went right to stein. So we do have some time to discuss this.16:17
arnewiebalcktrash/restore will require some wider changes16:18
arnewiebalckprobably a new state even16:18
smcginnisI'm sure. Almost like a manage existing.16:18
arnewiebalck‘recoverable’ or sth16:18
eharneyi think there's a lot of value in implementing this just in the driver rather than changing API semantics for it16:18
jungleboyjYeah.  That would be a notable effort but do think it is a good idea.16:18
smcginnisIn fact, maybe we can leverage managing existing to have another "recover from trash" option.16:19
smcginnisYeah, I should wait until I actually understand the proposal before going off on too many tangents. I'll take a look soon/16:19
eharneyif you want to be able to recover from the trash, you're going to have to rework how encryption keys get deleted too, which will turn into a very complex security concern16:19
arnewiebalcksmcginnis: that’d be great16:19
jungleboyjIf we do it in RBD only that doesn't preclude us from expanding it.  Right?16:19
eharneyjungleboyj: right, that's my thinking16:20
*** rcherrueau has quit IRC16:20
arnewiebalckI actually trimmed the whole thing down to a fast deleton as I thought “restore” would have no chance of being accepted …16:20
geguileoarnewiebalck: that was a good idea16:21
eharneyi think that's the right approach16:21
arnewiebalck… but, yeah, that was the original idea :)16:21
jungleboyjarnewiebalck:  Is a smart guy.16:21
arnewiebalckok, so how do we proceed? wait for some more eyes to check?16:22
*** vladiskuz_ has quit IRC16:22
smcginnisI think so.16:22
*** wxy has quit IRC16:22
jungleboyjarnewiebalck:  That sounds like the plan.  And it sounds like we are in agreement that Stein is the best target.16:22
arnewiebalckjungleboyj: ok16:22
*** wxy has joined #openstack-meeting16:23
arnewiebalckso we revisit next week?16:23
arnewiebalckor is that too short?16:23
smcginnisThat works for me. I should be able to review and understand it by then.16:23
jungleboyjI think for the time being we can work it through the spec and re-address here if things get complicated.16:23
smcginnisYeah, we may not need to discuss in the meeting if folks review the proposal and are fine with it.16:24
jungleboyjOk.  Anything else here?16:25

jungleboyj#topic Broken Doc Build.16:33
*** openstack changes topic to "Broken Doc Build. (Meeting topic: cinder)"16:33
smcginnisSo just so everyone is aware16:33
smcginnisLocal doc builds are currently broken.16:34
*** cloudrancher has quit IRC16:34
smcginnisGate doc builds were changed, so they currently do not enable warnings-as-errors.16:34
smcginnisSo some warnings ended up getting merged.16:34
smcginnisWhich when run locally through our tox target, ends up converting those warnings to errors and failing.16:34
smcginnisFixes the current warnings. ^16:35
smcginnisAnd I have proposed a job change:16:35
smcginnisThat would enable warnings-as-errors, but only for py3 runs.16:35
smcginnisSo if that is accepted, I would then put up a patch to switch our docs jobs to use that job template instead.16:35
e0nesmcginnis: +1 to treat warnings as errors16:35
jungleboyjsmcginnis: ++16:36
smcginnisIdeally, I hope every project eventually moves over to both running py3 and treating warnings-as-errors, but I don't think many are ready yet.16:36
jungleboyjThank you for fixing that.  How did the warning-as-errors in the gate get changed?16:36
smcginnisAnd will probably require a fair amount of work before they can.16:36
smcginnisThe job used to try to parse out the setup.cfg file for the warning flag.16:36
smcginnisBut with the latest guidelines, the thing it was parsing should no longer be there.16:37
smcginnisSo just wanted everyone to be aware of that. And to review and approve the warning fix. ;)16:38
tbarronsmcginnis: looks good, will copy the approach16:38
jungleboyjsmcginnis:  Will look at that after the meeting.16:38
jungleboyjtbarron:  ++16:38
smcginnistbarron: Cool, let me know if you run into any issues.16:38
*** annabelleB has joined #openstack-meeting16:38
smcginnisjungleboyj: That's all for that topic.16:39
jungleboyjOk, you are on the next one too.16:39
jungleboyj#topic Config-table directive16:39
*** openstack changes topic to "Config-table directive (Meeting topic: cinder)"16:39
* smcginnis warms up his fingers16:39
smcginnisOK, this one...16:39
smcginnisWay back in the day, when we had an openstack-manuals repo, there was a command to run to generate driver config option tables.16:39
*** simon-AS559 has quit IRC16:40
smcginnisSince then, we have moved docs in-tree in Cinder and that tool was taken out back and shot.16:40
smcginnisSo we have a bunch of stale tables, and folks have just been manually updating them.16:40
smcginnisTo address this, I've written a sphinx extension to do what that was doing manually.16:40
*** armax has joined #openstack-meeting16:41
smcginnisThis gets rid of the static tables and just needs the directive added to the drivers docs to pull in a table with any config options in the specified modules.16:41
smcginnisIt will dynamically parse that out and generate the table.16:41
e0nesmcginnis: cool. I'll review patches later today16:42
smcginnisIt's mostly the same format, with the only changes being getting rid of the (incorrect) group line at the top and showing when things are marked as deprecated.16:42
jungleboyjThank you so much for working on that.16:42
smcginnisIt probably should become an oslo_config extension, but I wanted to make sure it was working for our needs first.16:42
smcginnisThen I can look at moving it over someday if others need it.16:42
jungleboyjsmcginnis:  ++16:42
*** mrhillsman has quit IRC16:43
smcginnisI have a whole series to go through yet, but I'm holding off for now to make sure everyone is OK with this approach and that we don't find any oddities.16:43
smcginnisBut I think I've covered most of the different scenarios and looks OK to me so far.16:43
*** mrhillsman has joined #openstack-meeting16:43
jungleboyjsmcginnis:  Should we maybe send a note to the mailing list to try to get attention from other driver owners who aren't here?16:43
smcginnisThe current series starts with the addition of the directive here:16:44
smcginnisjungleboyj: I'm not sure if we need each driver maintainer on there since it's just a drop and replace.16:44
smcginnisBut I could if you have any concerns there.16:44
jungleboyjIf you are confident it will be ok then we don't need to.16:45
smcginnisIf anything comes up that looks concerning, let me know and I can try to pull in the driver maintainer(s).16:45
jungleboyjMakes sense.16:46
jungleboyjsmcginnis:  Anything else on that?16:46
smcginnisOnly real difference, other than the minor table tweaks, is some of these actually add or remove config options that have changed since the last time they were manually updated.16:46
jungleboyjsmcginnis:  And that is a good thing.16:46
jungleboyjOk.  Cool.16:47
smcginnisThat's probably all on that.16:47
jungleboyjOk.  And finally you again:16:47

SotKany updates diablo_rojo_phon?19:05
diablo_rojo_phonBarbican is going Friday.19:06
diablo_rojo_phonTalking to heat about maybe going this week, though more likely next week.19:06
*** cloudrancher has joined #openstack-meeting19:06
diablo_rojo_phonI thiiink that's about it here.19:07
SotKnice, glad things are still moving pretty smoothly there19:07
diablo_rojo_phonI guess I can note that the infra manual on making a project has removed launchpad mentions19:07
diablo_rojo_phonNow just talks about storyboard19:07
diablo_rojo_phonSo we aren't going to have more new projects we will have to migrate.19:07
*** jchhatba_ has quit IRC19:08
fungiyeah, i've got the barbican migration on my reminders19:09
SotK#topic In Progress Work19:10
*** openstack changes topic to "In Progress Work (Meeting topic: storyboard)"19:10
SotKI looked into fixing the bug where typing the full project name causes the save button to not be enabled19:10
SotKit turned out more complicated than I hoped and the real fix will be to update to a more modern version of ui-bootstrap19:11
SotKwhich means a bunch of churn renaming things to prefix uib-19:11
SotKI'll look at doing either that or a more short-term workaround this week19:12
SotKI also began working through my review backlog, I'll do more of that too19:13

SotKnice :D19:15
diablo_rojo_phonYep :)19:16
SotKanything else in progress?19:16
*** sshank has quit IRC19:16
diablo_rojo_phonNothing off the top of my head.19:17
SotKI don't think anything changed with the blocking stories this week, so I'll skip to discussion for nmagnezi19:18
SotK#topic Open Discussion19:18
*** openstack changes topic to "Open Discussion (Meeting topic: storyboard)"19:18
nmagneziSo, hello to the storboard team.19:18
nmagneziMy name is Nir, I'm a member of the Octavia core team.19:19
SotKhey :)19:19
nmagnezimigrated to storyboard some time ago, and we experience some challenges.19:19
nmagneziI gathered a list of issues raised by the Octavia community:19:19
nmagneziI would like to get some feedback from the team here on that list basically19:19
diablo_rojo_phonnmagnezi: oh cool. Looking now.19:20
*** yamamoto has quit IRC19:20
nmagnezijust to put things in context, we compere storyboard to Launchpad, the tool we used to work with. we'd really be happy to improve storyboard :)19:20
nmagnezioh, our PTL is here too :)19:20
nmagnezijohnsom o/19:20
diablo_rojo_phonI can go through the list and add links to stories that exist. I see one that's been resolved actually.19:22
diablo_rojo_phonThe Gerrit posting on the patches has been fixed nmagnezi19:23
nmagnezidiablo_rojo_phon, yup. one got resolved.19:23
SotKfor 1., is that happening whilst the project filter is still displayed?19:24
diablo_rojo_phonI'll definitely go through this list today though.19:24
diablo_rojo_phonThis is super helpful.19:24
SotKah, then that is also fixed but not deployed because it merged when our automation was broken19:24
diablo_rojo_phonSotK can you give this a look?
SotKI suspect our automation is still broken, I'll put that at the top of my list19:25
johnsomFor context from my side, there has been a lot of push back on using Storyboard.19:25
SotKdiablo_rojo_phon: I remember an in-depth discussion about that patch in a meeting a while back19:25
SotKI don't remember what the outcome was, I'll try to find some logs later19:26
SotKjohnsom: do you know which issues are causing the most pain?19:27
nmagneziif it helps, I'm willing to file stories for some of the topics there are new to you guys.19:27
johnsomThese are the top issues. This list got filled pretty quickly after it was proposed.19:28
*** armax has quit IRC19:28
nmagneziIHO, number 8 is causing a lot of issues and prevents us from doing things we would like to do, such as proactive backports19:29
diablo_rojo_phonjohnsom: Thanks for bringing this to our attention. We definitely want to do all we can to make you guys happy.19:29
diablo_rojo_phonSotK did we have a metadata fix yet?19:30
SotKnumber 8 is the only one I think needs discussion beyond "is it fixed yet or not"19:30
diablo_rojo_phonOkay shall we discuss now?19:30
diablo_rojo_phonSo. Is it another field we need to add or can we amend descriptions to support metadata?19:31
SotKI have pretty strong opinions about importance and affected projects19:31
SotKsee the "Complex Priority" section of for importance19:32
SotKas for affected projects; in StoryBoard's data model stories aren't directly linked to projects, they're only connected via tasks19:34
SotKand so the list of affected projects can already be obtained, just by looking at what the projects of the story's tasks are19:34
SotKI'd need to understand more how milestones are intended to be used to have an opinion on that19:35
*** cloudrancher has quit IRC19:36
johnsomI think some of the concern about these fields not being available is round making it hard to search or pin searches for stories.  Correct me if I remember incorrectly nmagnezi19:36
*** lpetrut has quit IRC19:36
nmagnezijohnsom, +119:36
johnsomPreviously I used milestone metadata in Launchpad to target certain bugs to be fixed by a given OpenStack milestone release. The team used it to see priority bugs that need to be worked on.19:37
nmagneziwe want to be able to search and filter by those fields, so we can eventually automate some of our workloads19:37
nmagneziwe do that with Launchpad for Neutron19:37
johnsomIt creates a bit more urgency than a long list of backlog bugs with no timing metadata19:39
diablo_rojo_phonMakes sense.19:40
diablo_rojo_phonI'm not opposed to adding another field for milestones.19:41
diablo_rojo_phonIt's definitely something we get asked about a lot.19:41
SotKI'm not strongly opposed, but I feel like its something that can already be done using a board or worklist of some kind19:41
diablo_rojo_phonI think the problem is that it can be done but not easily.19:42
*** hamdyk has quit IRC19:42
johnsomWell, and it's super hard to search on board placement, etc.19:42
SotKinteresting, searching on boards is something we haven't really given much consideration to I think19:43
nmagneziSotK, any more information we can provide to help you guys with that list?19:45
diablo_rojo_phonWe could add a search that like.. filters what's on the boards19:46
SotKdiablo_rojo_phon: yeah, its something I've sometimes wanted but never given real consideration to19:47
SotKsimilarly I wonder if actually adding some UI for due dates outside of boards will help19:47
diablo_rojo_phonNot currently...but I'll give it a look in more detail in about a half hour when I get back to a laptop from this lunch meeting.19:47
SotKlike, a way of finding things that are asserted to be due by that date19:47
diablo_rojo_phonnmagnezi: ^19:47
nmagneziwe can follow up on that list in next week's meeting, what do you think?19:48
diablo_rojo_phonThat would work too I would think?19:48
*** liyi has joined #openstack-meeting19:48
SotKnmagnezi: that would be a good idea I think19:48
diablo_rojo_phonnmagnezi: I won't be around next week but definitely should keep this on the agenda.19:49
nmagnezijohnsom, agreed? ^^19:49
SotK(I think that 6 and 10 are fixed or at least improved, but similarly the improvement for 6 isn't deployed)19:49
johnsomSure, NP19:49
SotKcool, I'll do my best to get the things we have fixed on it actually deployed in the production instance by then too :)19:50

*** dklyle has joined #openstack-meeting19:54
fungicatching up, it may be worth revisiting whether the milestone targeting is still useful. it used to be common practice across openstack services because the release team used it to report on which bugs were fixed at which milestones over the course of the cycle, but they ceased that practice some years ago which is part of why supporting it as a workflow in storyboard wasn't previously identified19:55
fungias a priority19:55
*** bobh has quit IRC19:55
funginow they instead merely leave comments in bugs noting the first release in which each was fixed (and i have!/story/2001806 to make the release tools do the same for sb)19:56
fungi#link!/story/2001806 Support StoryBoard in release tooling19:56

cschwedei heard there's a swift gathering here21:03
notmynametdasilva told me he's not here21:03
notmynameand torgomatic and clayg and timburke are in a meeting (that I left)21:04

*** simon-AS559 has quit IRC21:04
*** sshank has quit IRC21:04
notmynamehere's my weekly reminder that is still open and needs to land before the next release21:04
patchbotpatch 555245 - swift - Fix versioned writes error with url-encoded object...21:04
notmynameit fixes
openstackLaunchpad bug 1755554 in OpenStack Object Storage (swift) "Percent signs in object names cause trouble for versioned_writes" [High,In progress] - Assigned to Kota Tsuyuzaki (tsuyuzaki-kota)21:05
*** edmondsw has quit IRC21:05
notmynamelet's talk about
patchbotpatch 562943 - swift - Import swift3 into swift repo as s3api middleware21:05
notmynamekota_: how is the patch looking this week?21:05
mattoliverauo/ - sorry was a holiday in Oz yesterday so got confused this morning21:06
*** edmondsw has joined #openstack-meeting21:06
notmyname(did kota_ step away?)21:06
kota_tdasilva, m_kazuhiro, and pete reviewed it21:07
kota_notmyname: I'M here21:07
notmynamethat's good news21:07
* cschwede is still reviewing it, but looks pretty good so far21:07
mattoliverauAnd I'm in the middle of a review.. just haven't finished, I got busy21:07
*** arnewiebalck_ has quit IRC21:07
kota_then, yesterday, I acked all comments and fixed small things.21:07
notmynamekota_: is there anything found that is bigger than expected?21:08
kota_not so far imo21:08
notmynamedoes it seem like the plan we talked about last week is still working? (having a smaller set of people review it and land when they say it's good)21:08
cschwedenotmyname: what was your schedule, ie required merge date?21:08
cschwedei remember Thiago saying sth like today21:09
cschwedeor this week21:09
kota_it seems tdasilva still wants to make it by default but I still hold my opinion it's not now because of gete issue.21:09
notmynamekota_: what's the gate issue?21:09
notmynamecschwede: I don't have a required merge date for the s3api, but asap. the main contention is the upcoming feature/deep branch21:09
kota_basically, devstack21:09
kota_we have debstack gate to run functests21:09
kota_but devstack has custom proxy-server.conf that includes swift321:10
kota_then, s3api by default means double s3api compatible middeleware in the pipeline21:10
kota_then, almost of functests will fail21:10
cschwedekota_: can'T we pin swift in devstack to a specific hash before the s3api merge, and then follow up, unpin it and at the same time disable old middleware?21:10
cschwedeiirc that is possible21:11
*** edmondsw has quit IRC21:11
kota_so my plan is 1. merge it to the master, 2. fix devstack to use s3api, then, s3api by default.21:11
notmynameI agree that we should merge to master before turning it on by default. (but I support getting to an on-by-default asap)21:12
kota_cschwede: ah... i think it's possible21:12
*** edmondsw has joined #openstack-meeting21:12
kota_i mean, 'we can pin the version'.21:13
notmynameis swift3 added to the proxy pipeline for every devstack job?21:13
kota_but still not sure it works well for... setting up the gate.21:13
kota_1 sec21:13
kota_the related change is at
patchbotpatch 548938 - openstack-dev/devstack - Change devstack-swift to use keystone auth sample21:14
kota_it doesn't solve the problem directly, but attempts to resolve devstack making handmade pipeline.21:15
kota_it didn't get finished yet tho.21:15
notmynameoh ok. so it's a swift3-specific dsvm job21:16
notmynamethat adds swift3 to the pipeline21:16
notmynamewhich means we cannot add that test to the s3api branch and have it tests s3api middleware21:16
kota_yes, the is_service_enabled swift3 is true at L43021:17
*** edmondsw has quit IRC21:17
notmynameand we cannot turn on s3api middleware by default because *other* projects may have added swift3 to the pipeline and then will fail21:17
*** yamamoto has joined #openstack-meeting21:17
kota_and the swift_pipeline is based on tempauth pipeline in proxy-server.conf21:17
notmynamedid I understand that correctly?21:17
*** edmondsw has joined #openstack-meeting21:18
kota_yes, but only one project (i.e. devstack) i know exists as such a project, tho.21:18
kota_idk for any other projects.21:19
notmynameit sounds like there's some more investigation needed as to what is breaking when. (or to rephrase: I don't completely understand the problem yet)21:20
kota_oh, just we can ask to cschwede how it is on triple-O21:20
notmynamebut it doesn't seem like this is blocking a merge to master, correct?21:20
cschwedekota_: it's not enabled by default on OOO21:20
cschwedenot yet, that is :)21:20
kota_if we can make it as optional by default.21:20
notmynamethe proposed code can land, as-is. the proposed code is tested. adn the proposed-code doesn't break other projects21:20
kota_notmyname: if we can make it as optional by default, it doesn't block to get it merge.21:21
*** armax has quit IRC21:21
notmynameit is currently proposed as optional, right?21:21
kota_i think so21:21
kota_oh... i missed your mean.21:22
kota_absolutely true.21:22
kota_currently I proposed the patch to make s3api as optional21:22
*** edmondsw has quit IRC21:23
*** esberglu has quit IRC21:23
notmynamewhich means that it should be able to land on master as soon as it's reviewed.21:23
*** yamamoto has quit IRC21:23
mattoliverauOk so definitely optional first, then turned up will be a follow up after investigation and once master21:24
*** edmondsw has joined #openstack-meeting21:24
mattoliverau*turned on by default21:25
notmynameso if that's true, and it sounds like only small stuff has been found so far, then I hope that after mattoliverau and cschwede finish their reviews, then we will be able to merge s3api to master21:25
kota_+1 :)21:25
notmynamegood to hear21:25
notmynameok, let's talk about torgomatic's consistency engine patches.21:26
notmyname landed this week!21:26
patchbotpatch 555563 - swift - Multiprocess object replicator (MERGED)21:26
notmynamethank you21:26
*** annabelleB has quit IRC21:26
notmynamethat unblocks a few others that he'd been working on too that are based on that patch21:26
notmynamerledisez: thanks for helping out there. I saw your name on an email about one of those, I think21:27
notmynameok, let's talk about the really big one now21:28
notmynameacoles: what's the good work?21:28
*** rbudden has quit IRC21:28
acolesbased on timburke's experimentation last week we made some significant changes to the replication strategy21:28
*** edmondsw has quit IRC21:28
*** aeng has joined #openstack-meeting21:29
acolesthat is all now on feature/deep and Tim is continuing to trial sharding a monster db21:29
notmynameand current progress on that big DB seems to be going well21:29
mattoliverauNice work21:29
notmynameor at least going21:29
acoles...which is progressing :) ... but a little slowly :( so21:29
notmynameone important... yeah. it's slow21:29
notmynamebut making progress21:30
*** edmondsw has joined #openstack-meeting21:30
acolesso we're now trying to understand why it is so slow. It's on HDDs for a start.21:30
mattoliverauWe knew monster dbs would be a problem... But once it's on by default (in future) we only have to deals with monsters initially21:30
notmynamegiven the hardware that DB is deployed on, we are *not* going to wait for it to finish all the sharding work. at it's current rate, it will take about 50 days to finish with 143M rows21:31
acolesat the other end of the scale, a 1.2million row db on my laptop with no async pendings shards in about 3 mins!21:31
notmynamehere's the real question: when can we propose feature/deep to master21:32
notmynameI think we should definitely create a new feature/deep-review21:32
mattoliverauacoles: cool21:32
*** esberglu has joined #openstack-meeting21:33
*** armax has joined #openstack-meeting21:33
mattoliverauYup, it touches a bunch of places21:33
*** annabelleB has joined #openstack-meeting21:33
cschwedeacoles: any chance to test the 143m row db on an ssd node?21:33
notmynamecschwede: unfortunately no.21:33
mattoliverauWhat part seems to be slow? Scanning, cleaving (locally), replication?21:34
notmynameacoles: do you know? timburke would be better able to answer that, I think21:34
acolesscanning was less than an hour IIRC21:34
mattoliverauMaybe we can profile it and see what area may need to be improved (for the future)21:34
cschwedeare we sure this scales linear? ie 1.2 million = 3 minutes on ssd, 12 million at least in the range of a few hours max?21:34
rledisezdid you run iotop to check if an SSD would help?21:34
*** edmondsw has quit IRC21:35
mattoliverauOh nice21:35
acoleswith the recent changes we have tried to stamp on replication to the db21:35
mattoliverau(re: scanning time)21:35
acolescschwede: I'm going to make more tests on 2 million, 4 million etc21:36
notmynameyeah... hang on. uploading a screenshot21:36
*** edmondsw has joined #openstack-meeting21:36
*** esberglu has quit IRC21:38
notmynamejust really really busy drives. 50M async pendings in the cluster plus the sharding work21:38
notmynameie "just like a user would do"21:38
cschwedewell, on the other side - 1.2 mill = 3 min, 144mil should be around 360 min then = 6 hours, which means a factor of 200 between hdds and ssd. which sounds reasonable if only looking at iops?21:38
notmynameassumign linear scaling etc etc etc21:39
notmynamebut we expect it to get faster over time. as shardes are cleaved off, the workload should be distributed to other nodes. so it may be faster21:40
notmynamebut for now, it's slow21:40
notmynamebut it's making progress21:40
*** edmondsw has quit IRC21:41
cschwedei was just worried about the big gap between minutes and 50 days, but it might be totally reasonable on hdds21:41
notmynamewhich again gets back to "when can we merge to master?"21:41
* cschwede is curious about acoles tests with 2 and 4 million rows21:41
notmynameI've been talking with timburke about making some more DBs about that size too21:41
acolesnotmyname: re proposing to master, obviously we need to get to bottom of the speed issues, but at same time I am conscious that there will be bugs that will only be found by review21:44
* acoles admits he may write bugs, sometimes21:44
acolescschwede: I do it *deliberately* of course :)21:45
notmynamehere's a proposal. please tell me where it's wrong or how to make it better21:45
*** armax has quit IRC21:46
notmyname(1) mattoliverau and cschwede finish a review of s3api. assuming it's good, it lands on master within the next 24-26 hours. (2) I create the feature/deep-review branch upstream (3) acoles prepares the patch chain to propose there (4) we keep monitoring the progress on the big DB (5) when feature/deep-review has the patch chain proposed, we soft-freeze master and all review21:47
acoles+1 for soft freeze21:48
*** Tom-Tom has joined #openstack-meeting21:49
notmynameeveryone is amazed at that plan's brilliance and has nothing to say, or everyone is amazed at it's terribleness and is at a loss for words21:50
mattoliverauAnd others who reviewed s3api and have there comments addressed can also re-revoew21:50
kota_i don't have any objections we go soft-freeze when we have feature/deep-review. it should help the branch maintainer to concentrate to fix/discuss issues on the branch.21:50
mattoliverauSeeing as they might also already be close to a +2,21:50
*** edmondsw has joined #openstack-meeting21:50
mattoliverauBut I'll try and get the review done today21:50
*** timburke has joined #openstack-meeting21:51
kota_still want to keep my eyes the progress on (4) the progress on the big DB tho.21:52
notmynameyes, definitely21:52
*** Tom-Tom has quit IRC21:54
notmyname(I really am waiting on any comments)21:54
*** ssbarnea_ has quit IRC21:55
*** edmondsw has quit IRC21:55
acoleskota_: +1 point 4 is important to us too21:55
mattoliveraunotmyname: so sounds like a good plane.. the prepare the patch and landing may depend on 4 a bit.. so the timeline might need to expand. But the plan is good21:56
cschwedeplan sounds good to me too21:56
notmynamemattoliverau: well, yes, but I don't think we should wait for 50 days to see what happens before proposing something to master21:56
mattoliverauoh no21:56
acolesI am tentatively planning on a small chain of patches, hoping it will help reviewers grok the aspects of the change21:56
mattoliverauWe should totally make the steps happen. A d go make a shard-review branch21:57
acoleshard to know how that will work out until I start carving it up21:57
notmynameacoles: how long will you need for that?21:57
acolesnotmyname: ard to know how that will work out until I start carving it up ;)21:57
acolesmaybe a day?21:57
notmynameok, great. i'll propose the branch my today or tomorrow, so that should work well together21:58
acolesI'll most likely be derailed by tests breaking as the changes are separated21:58
