joehuanglet's look at feature implementation which wants to land in pike-301:03
zhiyuanI am working on improving our smoke test, I propose to use YAML to define our tests. here is the spec:
joehuanggood to know the smoke test improvement is on the way01:05
joehuangcould you please register a BP in launchpad too?01:05
xuzhuangI have completed job paginate_query, and I am working  on doing some tests01:05
*** RonghUI has joined #openstack-meeting01:05
joehuangfor pagination query, a BP is also welcome01:05
joehuanghi ronghui01:06
zhiyuantwo implementation patches based on this idea: and
zhiyuanto joe, so still on launchpad?01:06
Yipeitrying implementing LBaaS in multiple regions and importing external network01:06
*** iceyao has quit IRC01:06
joehuangat least now, we haven't migrate to storyboard yet01:07
joehuangto yipei, thank you very much, hope that LBaaS and external network importing could be landed in pike01:07
dongfengI think resource routing pagination feature can be landed in pike 3.01:07
zhiyuanok, will register a BP on launchpad01:07
Yipeiyes, i hope so, i try my best to make it01:08
joehuangI am very busy these days, will try to review patches AFAP01:08
yinxiulinsfc's update patch may be be landed in pike 301:08
joehuangseems that everything fine :)01:10

Yipeino from me01:11
yinxiulinno for me01:12
xuzhuangno from me01:12
joehuangto xuzhuang, thank you for the pagination patch01:12
joehuangcould you register a BP too?01:12
zhiyuanto Ronghui, has Xiongqiu tested his three patches? if so, I would like to try them out in my own environment01:12
*** litao__ has joined #openstack-meeting01:13
RonghUIhis has tested his patches01:13
joehuangpatch1 and patch2 should be merged for testing coverage, isn't it?01:13
xuzhuangyou mean job pagination also needs a bp?01:13
joehuangjob pagination is another patch, but not the patch for resource routing?01:14
RonghUIif you say the two patches merge into one patch and tested it, no for this situation01:14
zhiyuanpatch2 has been changed to use driver to implement, but I don't see code to load the driver01:15
xuzhuangyes, two independent patches01:15
RonghUIyes we try to fix it01:16
zhiyuanwe need to merget the three patches, otherwise the feature is not complete01:16
joehuangto xuzhuang, ok. then no BP is needed, but the API documentation update is needed, to describe in detail how the API will function01:17
*** wanghao has quit IRC01:17
RonghUIyes next version, the two patches will merge into one patch01:17
xuzhuangok, got it01:17
*** wanghao has joined #openstack-meeting01:18
joehuangplease review the smoke test spec, all new features should be added and tested with its own smoke test cases, so the spec is important for all01:19
joehuangwithout smoke test cases, the feature quality has no guarantee.01:20
zhiyuanyeah, would like to hear your opinion whether the design of the YAML schema is reasonable01:20
Yipeiok, got it01:20
joehuangbecause smoke test will test the system on living two region openstack together tricircle, so only such an real environment can make sure the feature work.01:21
*** iceyao has joined #openstack-meeting01:22
joehuangpassing smoke test is basic requirement for all features, though it comes later, but we need to make it become the gate for all features.01:22
joehuangother topic?01:23
RonghUIno for me01:23
dongfengno for me01:23
zhiyuanthe YAML file is also usable for your local test during feature development, you can write a YAML then run it to test your feature, no need to type the long command again and again01:23
zhiyuanno for me01:23
Yipeino for me01:24
xuzhuangno for me01:24
joehuangok, if there is no other topic, we can end the meeting a little early, and continue discussion in #openstack-tricircle if needed01:25

trinathstung_doan: there is a spec in debate for cVNFs05:26
YanXing_ani want to talk about something that chinamobile doing in tacker, what do you think?05:27
jankitung_doan, gongysh the issue is that tosca can define deeper hardware level configs while dockerfile cann't05:27
trinathsYanXing_an: +105:27
jankialso there is no definition available to map tosca elements to dockerfile05:27
tung_doanYanXing_an: +105:27
gongyshjanki, why do you need a dockerfile?05:28
gongyshdockerfile is for creating a docker image.05:28
jankigongysh, to create a docker container from that05:28
jankiya. so that image will be used05:28
tung_doanjanki: it requires a lot of time. I just hope we merge this bp in Pike and move development part to Queen release05:29

*** openstack changes topic to "Supercomputing BoF (Meeting topic: scientific-wg)"11:02
verdurinGood afternoon.11:02
oneswigFirst item was that the submission deadline is approaching for BoFs at SC11:03
oneswigWhich is in Denver the week after the Sydney summit11:03
oneswigb1airo: do you have the deadline to hand?11:03
oneswigAt SC2016 we did a panel session which pretty much filled a big room11:04
*** edmondsw has joined #openstack-meeting11:05
oneswigThe question to discuss is, is there appetite for putting something on for SC again?11:05
b1airoend of July off the top of my head...11:05
verdurinoneswig: was there something at ISC?11:05
oneswigverdurin: nothing official AFAIK11:06
oneswigMy colleague John attended, I did no.11:06
b1airoyep 31st July11:06
*** jamesmcarthur has quit IRC11:06
b1airoi would like to do something at ISC next year11:06
oneswigb1airo: me too11:07
*** ykatabam has quit IRC11:07
oneswigOne action on SC - I think we should check with hogepodge to see if he's returning.11:07
*** tobberyd_ has joined #openstack-meeting11:08
oneswigThere's also the possibility of a second edition of the book we wrote, which was very popular at the conference11:08
b1airoyes good idea11:08
oneswig#action oneswig to follow up on book and foundation attendance for SC11:08
b1airoso who, if anyone, is planning to attend SC17 ?11:08
oneswigI might - its on the way home from Sydney for me11:09

oneswigre: openstack summit - I had a look at submitting papers, are the categories all changed from last time?11:10
oneswigb1airo: I think most WG members at SC16 were from the US time zone, we should follow up with this next week11:11
b1airoi haven't looked yet to be honest, don't really think i've got enough new material to warrant speaking11:11
*** tobberydberg has quit IRC11:11
verdurinCan't say yet whether I'll be at SC.11:11
oneswigwondered if the new format meant fewer categories11:11
b1airothe TPC was interesting11:12
b1airotechnical programme committee11:12
b1airofor SC17 I mean11:12
oneswigsubmissions already selected for presentations?11:13

b1airoonly a handful accepted for the clouds and distributed computing stream11:14
*** bollig has joined #openstack-meeting11:14
b1airoi'm still working on shepherding one of them, but that's turning out ok now11:15
priteauoneswig: she's chair of the Clouds & Distributed Computing committee11:15
priteauSo it's very likely she'll be there11:16
b1airoyeah i expect kate would be at the conference itself given she is chair, but i suppose you never know - she did say her travel diary was pretty crazy11:16
oneswigb1airo: after seeing a few talks last time I assumed the bar was pretty high, perhaps it's worth having a go next time round11:16
b1airooneswig, yes i think so11:16
oneswignoted for 2018 :-)11:17
b1airoprobably a practice and experience paper11:17

oneswignoggin143: in a cell or a separate deploy?11:20
b1airocool! i have been wanting to ask you guys about that as i thought i'd heard you had it going with cellsV1 and was interested to know if there were any gremlins there11:20

*** jaypipes has joined #openstack-meeting11:23
oneswigb1airo: too good! :-)11:23
oneswigOK - want to talk THP?11:24
oneswig#topic b1airo's issues with THP11:24
*** openstack changes topic to "b1airo's issues with THP (Meeting topic: scientific-wg)"11:24
b1airoi don't have a great deal of detail on this yet sorry but maybe someone will just know what our problem is11:25
b1airohere's hoping!11:25
oneswigWhat are the symptoms?11:25
b1airobasically we have noticed on some of our virtualised HPC nodes that certain jobs sometimes run very slowly11:25
b1airothe guests are CentOS7 backed by hugepages (either static or THP) on Ubuntu hypervisors (4.4 kernel)11:26
b1airothe THP issues are inside the guest itself11:26
b1airothe host THP usage stays steady after the guest is started11:27
verdurinb1airo: only with CentOS 7 guests, so a wide disparity in guest-host kernels?11:27
*** ianychoi has quit IRC11:28
b1airoso far we only have data for CentOS7 guests as we don't yet have a repeatable trigger and so have not been able to narrow things down or look at kernel bisections etc11:28
b1airoin the guests, when performance goes bad we see very high system time11:28
b1airoand when khugepaged runs periodically it uses noticeably more CPU than normal11:29
oneswigIs there some kind of steady-state activity that can provoke this?  What I'm getting at is stochastic kernel profiling using perf -
b1airothis seems to be related to THP defrag / memory compaction, as disabled defrag makes the high system time disappear11:30
b1airooneswig, perf is a good suggestion11:30
oneswigonly problem is, you need to provoke the problem continuously for (say) a minute11:31
oneswigto get a sample11:31
b1airoas we're suspecting some kind of memory fragmentation issue we've started collecting into influx (with grafana bolted on) vmstat and buddyinfo data11:31
*** wxy- has joined #openstack-meeting11:31
b1airofor all compute guests11:32
b1airowe also see a high rate of compact_fail in the THP counters11:32
*** jamesmcarthur has joined #openstack-meeting11:32
oneswigWhat are the causes of failure - any thoughts?11:33
b1airoit seems like it could be some interaction with pagecache as when we drop_caches the compact_fail stops the dramatic increase and hugepage count goes up again11:33
b1airoso far we haven't seen any obvious job/application patterns in the slurm logs11:34
b1airobut i note that THP only applies to anonymous memory, so currently linux does not hugepage-ify pagecache11:34
*** dmacpher has joined #openstack-meeting11:35
b1airothe one thing we do have is an application that runs dramatically faster with hugepage backing in the guest (as well as the hypervisor), so we do have a test-case to detect problems that should finish in 1min if working properly11:36
oneswigDoes it count as a failure if there's insufficient contiguous physical memory to create a hugepage?11:36
*** thorst has quit IRC11:36
b1airooneswig, that's a great question - i have not had a lot of luck finding murky details of the compaction algorithm11:37
*** jamesmcarthur has quit IRC11:37
*** wxy- has quit IRC11:37
b1airothere is an LWN article from about 2010 that talks about it generally but it is not in relation to THP11:37
oneswigHopefully, failure is nothing more than that - no room in the inn11:38
oneswigand might explain why evicting caches indirectly helps11:38
b1airoin the default CentOS7 (and maybe RHEL7) guest setup /sys/kernel/mm/transparent_hugepage/defrag is enabled11:38
b1airowhich means that the vm (as in linux virtual memory management, not virtual machine) will perform defrag on-demand to allocate a hugepage in response to a page fault11:39
*** rbartal has joined #openstack-meeting11:40
*** efried_backJuly5 is now known as efried11:40
b1airoi think that is why we see the system time drop off when 'echo never > /sys/kernel/mm/transparent_hugepage/defrag', as we stop slowing down page faults and just fall back to using 4k pages11:40
oneswigI wonder if a paravirtualised guest sees some data passed through on memory mapping, similar to numa awareness11:41
b1airohmm no idea11:41
oneswigI'm trying to picture these interactions between the page mapping of host and guest and not doing very well...11:42
*** hashar has quit IRC11:42
b1airoi'm still wondering if there is not a much simpler way to do guest to physical memory mappings than the 2-dimensional method used today11:42
oneswigI think what you've got here is a top-drawer presentation subject for Sydney - if you get to the bottom of it11:42
oneswigKeep us updated?11:43
b1airoif you can assume a guest's memory is mlocked (reasonable for high-performance use-cases) then it seems like you can reduce the guest page lockup to an offset11:44
b1airobut i'm sure that's a stupidly naive idea and if i find the right mailing list someone will suitably shoot me down :-)11:44
b1airooneswig, fingers crossed!11:45
oneswigShould we move on?11:45
b1airowe'll be trying to build some nice graphs to visualise it more and hopefully i can share something pictorial next week11:46
oneswigThanks b1airo, be really interesting to see what you find11:46
oneswig#topic scientific application catalogue11:46
*** openstack changes topic to "scientific application catalogue (Meeting topic: scientific-wg)"11:46
oneswigOK, I had an action to investigate Murano on tripleO11:46
*** slaweq has joined #openstack-meeting11:46
oneswigverdurin: you did too - any luch?11:46
oneswigI mean luck?11:47
oneswigI got my TripleO deploy to the point where I can add Murano, that's all I managed alas11:47
oneswigI did however have discussions with several others who were also interested in this kind of service11:48

oneswigverdurin: you there Adam?11:49
noggin143we’re looking at Murano this summer. Given that the OpenStack application catalog at is being retired, it would be interesting to share some scientific apps11:49
b1airois it, totally missed that - how come?11:49
noggin143it was competing with other repositories like bitnami and dockerhub11:50
oneswignoggin143: is the CERN investigation being done in a way that we can participate in?11:51
*** hashar has joined #openstack-meeting11:51
noggin143it’s a summer student project for the next few weeks and they will do a writeup once it is done.11:51
verdurinBack now oneswig11:52
oneswigSounds useful, let's keep it on the agenda.11:52
oneswigHi verdurin - any luck with you?11:52
verdurinoneswig: not yet. Hopefully very soon.11:53
*** slaweq has quit IRC11:53
oneswigme too... it's a three horse race :-)11:53
oneswignoggin143: is there an intern assigned for this work?11:53
oneswigwe could start a therad11:54
b1aironoggin143, so was the reason to do with those other places having larger contributor communities and so the openstack catalog looking bad because it is so sparse ?11:54
noggin143and because it was viewed as a competitive solution. Better to integrate with other communities than have our own11:54
priteauThe mailing list thread about the app catalog is
b1airois there an alternative that would allow us to share murano apps for example?11:55
*** jamesmcarthur has quit IRC11:55
b1airothanks priteau11:55
noggin143I think we’re probably best off just setting up a github repo and the syncing to it11:56
b1airoit predates my recent decision to try and read more of openstack-dev again11:56
oneswigb1airo: the NSF guys had a Murano catalog in draft form11:56
oneswigand were sharing packagings on that.  Don't think it went mainstream but we should pursue that.11:57
noggin143NSF work sounds interesting.11:57
oneswig#link presentation here
b1airoMurano on Nectar is getting a steady flow of contributions now, i haven't actually looked at our index in a while but i see the "new murano package" tickets come in for review, maybe one every fortnight at the moment11:59
oneswigAnything more - AOB?11:59
b1airothere is a relevant ML thread on rebranding WGs to SIGs11:59
oneswigb1airo: sounds like it has enough critical mass on Nectar to be self-sustaining11:59
b1airowe would certainly love to share with other science clouds12:00
verdurinlove to hear more about it, b1airo12:00

ad_rien_Maybe you can introduce you a bit more and explain what are you doing ? and what is your target?15:08
ad_rien_banhgao (Daniel ?)15:08
ad_rien_do you want to tell us a bit more about fbk ?15:08
ad_rien_and why you are there (I can do it if you prefer but I think you are the most relevant person to do that ;))15:09
ad_rien_banhgao:  ?15:09
banhgaoHello everybody15:09
ad_rien_(FYI, I just add a smalll sentence in the pad line 875)15:10
*** dmacpher has quit IRC15:10
banhgaoFBK is a research foundation in Trento (Italy). Our research unit is currently working on a fog computing platform.15:11
ad_rien_dunno whether we should say more but if you want to, please the floor is yours15:11
ad_rien_so let's move forward.15:11
ad_rien_Second announcement, I encourage you to go through the Openstack etherpad I put line 87715:12
ad_rien_it is rather interesting to see what are the current technical challenges core developers are facing.15:12
ad_rien_and that's all from my side15:13
ad_rien_Does anyone want to announce something special ?15:13
*** bkopilov has quit IRC15:14
par`Do you have any insight in OPNFV?15:14

par`I hear of a new group being started that relates to this.15:14
ad_rien_I'm still waiting for some informations from jamemcc ?15:14
ad_rien_I don't know whether he is online. I put this point in the open discussion.15:15
jamemccJOined late15:15
ad_rien_par`:  do you have some links related to this new group?15:15
ad_rien_jamemcc:  Hi, good to see you online.15:15
par`give me min .... Bryan Sullivan from AT&T created a wiki on it.15:16
ad_rien_We were asking whether you have some news regarding what's happen on the NFV/LCCO and the gross WG chair meeting ?15:16
jamemccNo new group from my perspective - FYI - I am chair of the Large Contributing OpenStack Operators (LCOO) wG15:16
par`here is the link I saw:
ad_rien_par`:  ack. jamemcc: do you have some news regarding the cross WG chair meeting?15:17
jamemccYes - we ahve been working to get better communication channel going across the Workign Groups - incuging this one, Operators Telco NFV, LCOO and OPNFV15:17
ad_rien_#link a new WG on the OPNFV side.15:17
jamemccUser Committee want's to have it as part of User Committee Meetings so it was just a matter of when.15:17
ad_rien_#action ad_rien_ should give a look to this new WG.15:17
*** yamahata has joined #openstack-meeting15:18
jamemccWe had a poll and the User Committee watend to query/urge a few more to participate and they have now and the proposal is for the first such cross WG meeting at User Committee to be July 1915:18
par`jamecc: what is the next step from our perspective?15:18
ad_rien_jamemcc:  I thought you opened a doodle to try to fix a final slot?15:18
ad_rien_jamemcc:  ok. Did they send an official email/invitation? Can you please tell us the time on July, the 19th?15:19
jamemccThis is mostly documented in User Committee ML:
ad_rien_#link first cross WG discussion15:20
jamemccHmm - I see a issue - In the ML - I put JUly 1715:21
jamemccBut it shoudl eb ealry on a Wednesday - So July 1815:21
jamemccJuly 1915:21
*** rcernin has quit IRC15:21

ad_rien_I will be offline unfortunately15:22
ad_rien_can you please keep us in touch?15:22
ad_rien_just send me a mail if it is possible?15:22

ad_rien_Last meeting we did not discuss the use-case15:23
ad_rien_So I would propose to start by this item today15:23
ad_rien_Is it ok for everyone ?15:23
ad_rien_par`: the floor is yours15:23
par`Thank you.15:23
*** dmacpher has joined #openstack-meeting15:24
par`I have shared some slides on the mailing list yesterday.15:24
par`It would be good for everyone to have a look and give feedback.15:24
par`Use case is an ambiguous term.. and it encompasses many things that we have to address.15:24
par`I suggest we agree on the aspects that need to be addressed for specific use cases.15:25
par`1- are we talking about edge cloud or about federated cloud?15:25
*** XueFengLiu has quit IRC15:25
par`2- are we talking about IOT, or AR or another type of service15:25
par`3- How do we divide Openstack components among nodes.15:26
ad_rien_edge is the priority of this WG. considering that an edge platform is an infrastructure composed of several edge data centers15:26
ad_rien_2./ can you please clarify what do you mean by AR ?15:26
par`Augmented reality15:26
ad_rien_3./ this is the overall objective of this WG .)15:26
ad_rien_of or 2./ I think we can consdier both15:26
ad_rien_why not?15:26
ad_rien_I mean the industrial internet and the Tactile internet are both leveraing IoT and AR.15:27
* ad_rien_ is looking for a link 15:27
par`Agreed... I think they all are in scope. But wouldn't it be good to identify which one we focus on.... in terms of use case. So we can move forward on the technical tests15:28
banhgaoIn our work at FBK we are working on mobile edge platform to support IoT devices. We can provide some use cases for that.15:28
*** Nel1x has joined #openstack-meeting15:29
par`banhgao: do you already have an architecture in mind that we can use as a starting point?15:29
ad_rien_Telcos with CRAN use-cases also need FEMDC infrastructures15:29
*** bknudson has quit IRC15:30
*** andreas_s has quit IRC15:30
ad_rien_They had a paper to the last IEEE CloudCom conference15:31
*** bknudson has joined #openstack-meeting15:31
ad_rien_that presents the architecture at coarse-grained15:31
banhgao@par` By now we are using a single cloud with an intermediate fog level and gateways to connect to IoT devices. I can leave some links in the pad15:31
ad_rien_unless I missunderstood, the idea was a central DC and several DCs deployed at the edge15:31
*** janki has quit IRC15:31
ad_rien_banhgao:  can you please put the link in the pad.15:32
par`That is definitely an interesting case for this group. If you can share the link, I will add it to the deck.15:32
*** oidgar has quit IRC15:32
par`The last part of the use case would be the lifecycle operations we consider.15:33
par`Are we looking at measuring how fast we can instantiate 1000 VMs?15:33
par`Are we looking at measuring how easily we can do failure recovery ?15:33
par`I have listed about a dozen such operations in the deck.15:33
ad_rien_#link a view of IoT/Industrial Internet and Internel of skills (aka tactile internet)15:34
ad_rien_OK so let's try to define concrete actions.15:34
ad_rien_For the next time, every person interested by the use-case action should put his/her comments in the slides.15:34
ad_rien_Do you think it is enough to move forward ?15:35
par`How many use cases do we want to target? Should we start with just one? and then move forward?15:35
*** gyee has joined #openstack-meeting15:36
ad_rien_Yes I think we should identify a few (let's say no more than 5)15:36
ad_rien_and then try to identify which is the simplest and the most difficult/complex15:36
ad_rien_in terms of scientific/technical challenges15:36
*** manjeets_ has joined #openstack-meeting15:36
ad_rien_I think that the use-case that is envisioned by FBK is something we can deliver15:36
*** psachin has quit IRC15:37
ad_rien_without involving important changes in OpenStack15:37
par`actions would be to fully documeent the FBK use case for next week so we can vote on it.15:37
ad_rien_more distributed scenarios (i.e. involving a huge number of DCs at the edge can become difficult)15:37
par`and then to come to the meeting with additional use cases.15:37
ad_rien_banhgao:  do you think it is feasible according to the vacation?15:37
ad_rien_Can you consolidate informations in the current presentation15:38
ad_rien_#link current use-case presentation15:38
ad_rien_for the next meeting (i.e. on July, the 19th if I'm right) ?15:39
par`If people can edit the document, this is good. If not, please send updates to me and I will do the edit.15:39
ad_rien_#action ad_rien_ go through the google use-case presentation and add comment (if not possible send it to par`)15:39
*** msimonin has joined #openstack-meeting15:39
ad_rien_#action all do the same ;)15:39
*** bkopilov has joined #openstack-meeting15:40
par`ad_rien_: one last point.15:40
par`I feel networking requires special attention.15:40
ad_rien_please elaborate a bit more ?15:41
banhgaoWe can provide detailed information about the platform and the use-cases for the next meeting.15:41
par`So when people review and comment, it would be good if they shared thoughts on how to implement neutron or other networking solution at the edge.15:41
ad_rien_#action banhgao will provide additional information related to the FBK use-case15:41
par`e.g. should we use L2 or L3 networking at the edge.15:41
ad_rien_banhgao:  thanks ack15:42
ad_rien_par`:  +115:42
par`that is it for me.15:42
ad_rien_but just to avoid missunderstanding15:42
ad_rien_are you talking about control plane exchanges or data plane or both?15:42
par`My initial focus was control plane.... but the deck does touch on user plane too.15:43
ad_rien_FYI, there will be a new PhD applicant (starting next october) between Inria and Orange to deal with those challenges.15:43
ad_rien_so right15:43
ad_rien_I agree15:43
ad_rien_is this point already highlighted in your slides?15:43
ad_rien_If yes great, if not, may I ask you to add  a note please?15:43
*** armstron_ has quit IRC15:44
ad_rien_ok I will have to go from my side.15:44
par`#action par` to add a note to slides about networking.15:44

ad_rien_it is related to the deadline for submitting presentations to the next summit15:44
*** armstron_ has joined #openstack-meeting15:44

*** msimonin has left #openstack-meeting15:49
kgiustiWe need to define the message bus topology/configuration within the context of the use-case for the tests to have significant meaning IMHO15:49
*** armstron_ has quit IRC15:49
kgiustithat's all I have for today.15:49
par`kgiusti: aren't there things we can move forward that are shared accross use cases?15:49
kgiustipar`: certainly the messaging-level tests15:50
kgiustito get an understanding of the behaviors of different tech and topologies15:50
*** armstron_ has joined #openstack-meeting15:50
*** Apoorva has joined #openstack-meeting15:50
par`So it does make sense to focus on messaging-level tests for now while we discuss use cases.15:51
kgiustiand we can do some base line rally tests for sure15:51
kgiustipar`: yeah, that's my inclination.15:51
par`Are you taking that action?15:51
kgiustiwe can 'optimize' the message bus to the particular use case, then analyze that.15:52
kgiustipar`: sure!15:52
par`#action: kgiusti to focus on messaging-level tests and do some base line rally tests while work on use cases continue.15:52

rcherrueauSo, as expected ...15:54
rcherrueauthings don't work out of the box!15:54
rcherrueauThe first issue is applying all database migration computed by SQLAlchemy-migrate15:54
rcherrueauTo make things clear for everyone: Keystone relies on SQLAlchemy-migrate to deal with database schema changes15:54
rcherrueauI don't look into the code of SQLAlchemy-migrate but I think it uses some "introspection/intercession magic" on database to gather information on the current state of the schema and then apply migration.15:54
rcherrueauOf course, this magic stuff is not implemented by cockroachdb dialect.15:54
rcherrueauI am currently working on a minimal example code to discuss with cockroachlab folks directly.15:54
*** caboucha has joined #openstack-meeting15:55
rcherrueauFortunately, things are not stuck here.15:55

jgriffiththat's the whole shared-connection debate thing16:17
jgriffithif people have concerns here or use that model we REALLY need your help at this point16:18
jgriffithotherwise, we will assume everything works just like LVM and merge that version; if you're broken, you're broken16:18
ildikovThis point equals NOW :)16:18
smcginnisDo we have tempest tests that go through the new path yet?16:19
jgriffithsmcginnis getting close; but CI's wont' pick it up until nova merges16:19
*** galstrom is now known as galstrom_zzz16:19
jgriffithand we can't merge that until we know we don't break everyone...16:19

jgriffiththat's actually not a bad way to look at it either16:20
*** bobmel has quit IRC16:20
DuncanTjgriffith: Can you use a cross-repo depends on tag to test the nova patch befor eit merges?16:20
*** bobmel has joined #openstack-meeting16:21
jgriffithDuncanT yeah, we do that already, but that's not a requirement for CI and it doesn't matter because our CI's aren't running against nova patches16:21
jgriffithwhat I mean is that we have been doing cross-project depends on in the nova patch16:21
DuncanTjgriffith: Just post an empty cinder patch that depends on the nova patch, no?16:21
smcginnisDuncanT: Yeah, and I don't know if any third party CI is set up yet to handle cross repo dependencies correctly yet.16:22
DuncanTjgriffith: Ah, you're way ahead of me then, I'll ggo back to sleep :-)16:22
jgriffithDuncanT again, I don't think most of the 3'rd party systems do the cross-project checks, but we could try that16:22
smcginnisDuncanT: Hah16:22
jgriffithI guess there's one way to find out :)16:22

johnsomI suspect folks are not used to the new time yet and/or on vacation as it's a holiday week in the US17:24
xgerman_and I kicked around the idea to merge that in Pike as a basis for Active-Active drivers in the future17:24
johnsomHa, lots of red at the moment...  Grin17:24
xgerman_yep, but there is some time before Pike deadline17:24
*** hieulq has joined #openstack-meeting17:25
johnsomYes.  As long as it doesn't bring risk into Pike I am ok starting to merge some of that if it is ready17:25
xgerman_I don’t think it adds risk will just be “dead” code without the rest17:25
johnsomI will try to do an OSC plugin release today.  It will have the bug fix for l7rules.17:27
*** gans has quit IRC17:27

*** openstack changes topic to "upcoming events (Meeting topic: swift)"21:03
notmynamethe PTG and the summit are coming up21:03
notmynamethat's the etherpad to start collecting topics for the PTG21:04
notmynameplease register for the PTG and get your hotel soon so that you have a close place before they are all booked21:04
tdasilvais the conference hotel already full?21:05
notmynameI hope not!21:05
notmynameI just booked mine last week, so I'd guess there is still room21:05
notmyname has all the PTG info21:05
acolesI booked ok last week, except the Saturday before was full21:06
notmynamethe schedule for the PTG will be similar to the last one in atlanta: monday-tuesday will have a lot of "cross project" things to invest in. wednesday-friday will have rooms dedicated to the swift team21:06
notmynameplease, *please* encourage all ops people to attend the PTG21:06
jungleboyjJust checking.  There is room.21:06
*** dprince has quit IRC21:06
notmynameif you have to choose, choose the PTG over the sydney summit21:07
mattoliverauthe last one was good, I recommend it to others21:07
notmynameyeah, I expect it to be a very productive week21:07
joeljwrightwe need a mattoliverau lifesize cutout21:07
mattoliverauwell maybe not life sized.. you could at least make it slimming ;)21:08
notmynamethe other upcoming event, of course, is the summit in sydney. info at
*** galstrom_zzz is now known as galstrom21:08
notmynamethe call for presentations for sydney is only open for about another week, so if you're interested in giving a talk, now's the time to submit it21:08
notmynamenote that the sydney summit is only 3 days long21:08
mattoliverau3 days is teh dumb21:09
notmynamewhile I expect to be going, I do not expect there to be much in the way of deep, productive swift team time (ops or otherwise)21:09
notmynametherefore, that is why I am encouraging all devs and ops to be at the PTG instead21:09
mattoliverauexcept for visiting the beach house right?21:09
mattoliveraunotmyname: ^21:09
notmynamefor most of the world, sydney is a *very* long and expensive trip for a 3 day conference that doesn't have any dedicated time for our team21:10

notmyname#topic docs migration work21:13
*** openstack changes topic to "docs migration work (Meeting topic: swift)"21:13
notmynamehave you been following the mailing list threads about the docs migrations?21:13
notmynamethe summary is that for various reasons, the stuff that is currently managed by the docs team will be moved into respective project repos21:14
notmynameand the work to do so is on each team (in large part because nearly the whole docs team got laid off at the same time mattoliverau did :-( )21:14
notmynameI was traveling last week and holiday early this week, but i'm starting to look at that migration work now21:15
jungleboyjHow about that 1.2 Gig Docs repo?21:15
notmynameheh, only 760MB ;-)21:15
notmynameso there's a couple of steps here21:15
jungleboyjYeah, after I did a build it ballooned and almost killed my VM.  :-(21:15
kota_sounds so huge docs21:15
notmynamefirst is that we'll have to import a bunch of stuff to the swift and swiftclient repos21:16
*** Sukhdev has quit IRC21:16
notmyname*after* that, we can rearrange, de-dup, etc21:16
jungleboyj<little kids voice>  So big! </little kids voice>21:16
timburkebut that's across all projects, right? not 3/4 gig just for swift?21:16
jungleboyjtimburke:  Right.21:16
notmynametimburke: correct. it's just the source repo21:16
*** jamesmcarthur has quit IRC21:16
notmynamejungleboyj: have you already started looking at the docs migration work for swift?21:16
tdasilvanotmyname: isn't the first step to start using the new openstackdocs theme?
notmynamecause if so... yay!21:16
patchbotpatch 478402 - swift - Switch from oslosphinx to openstackdocstheme21:16
jungleboyjnotmyname:  No, I was supposed to do it for Cinder.21:17
notmynamejungleboyj: ah ok21:17
notmynametdasilva: perhaps. I'm getting caught back up to it. seems like that would be a simple thing to do21:17
jungleboyjPanic'ed today when I started noticing that our links out on the web are broken.21:17
notmynameyeah, I heard that happened (all the 404s)21:17
jungleboyjnotmyname:  Depending on how long this takes for Cinder I could help out with Swift.21:17
notmynamejungleboyj: cool. ping me when you're done with cinder, and we'll see where the swift migration is21:18
tdasilvanotmyname: i wish, I think it really breaks the look and feel of the docs, so I think we will have to do meaningless tweaks over time just for things to look nice again :/21:18
notmynamejungleboyj: try to go "swiftly" on cinder21:18
notmynametdasilva: :-(21:18
jungleboyjnotmyname: Sure.  Is anyone starting on it?21:18
*** rderose has quit IRC21:18
notmynameI am21:18
jungleboyjnotmyname:  Ok, let me know if you have questions.  I have found, already, that the build fails when just copying things over.21:19
jungleboyjThey have also removed everything from the openstack-manuals tree.21:19
* notmyname was hoping for a few days of work and be done with it21:19
claygtdasilva: what breaks?  patch 478402 looks fine?21:19
patchbot - swift - Switch from oslosphinx to openstackdocstheme21:19
jungleboyjSo you need to go back to the 'before-migration' tag.21:19
tdasilvaclayg: builds don't break, it's very subjective, I'm just used to the old looks, so I don't like how things look in the new theme21:20
*** baoli has quit IRC21:20
tdasilvaclayg: compare:
claygoh... sorry I don't have opinions on that sort of thing21:20
claygyeah I mean both pages seems to have the same information :\21:21
claygI assumed since someone spent time on it they must think one is better than the other?21:21
notmynamewe can work on the prettiness later21:21
*** rderose has joined #openstack-meeting21:22
claygmaybe one has the denting wrong?21:22
notmynameyes, this work is not insignificant, and it is being forced upon us as a team by external forces21:22
jungleboyjnotmyname:  ++21:22
jungleboyjI was planning to just get Cinder's stuff moved and then work on cleanup afterwards.21:22
claygit sorta looks wrong on both tho - un-even21:22
notmynamebut docs are important, so we need to do it21:22
clayglet's do it!21:22
notmynameI'll start, and hopefully finish, without needing to bring in too many other people. but I may need to ask for help, depending on how it goes21:23
*** slaweq has joined #openstack-meeting21:23
notmynamebut also since this is a "do it or lose your docs" sort of situation, I expect the eventual reviews to be cursory "yup, content moved, +2/+A21:23
notmynameso don't freak out when a lot of new stuff gets added :-)21:24
jungleboyjnotmyname:  Let me know if I can help.  I am hoping to get a couple of patches up yet today for Cinder.  I am traveling tomorrow but will probably spend Friday and the weekend working on the rest.21:24
acolestdasilva: did someone figure we're all getting older and increase the font size accordingly? ;)21:24

patchbot - swift - Unify Putter and MIMEPutter into a single class.21:27
claygahh... so it *is* per part - that's EPIC21:28
mattoliverauit kinda does it when it needs it.. I wonder if that can be cleaned up to be in one place.21:28
kongmorning, guys21:28
torgomaticnothing to know yet; we'll see how things shake out21:28
*** ijw has quit IRC21:28
torgomaticI had some thoughts around using different verbs for versioning instead of putting it in the path, but no code yet21:28
claygkong: I think mattoliverau is telling us we can probably merge patch 470158 - so that's exciting!21:28
patchbot - swift - Write-affinity aware object deletion21:28
*** ijw has joined #openstack-meeting21:28
torgomaticthat way, we get a 405 when the object server is old, and if we need v3 or v4 or whatever, we just have to make up and implement some new verbs21:29
kongclayg: hooray!21:29
mattoliverauI'll go give it another whirl today, and if all good I'll give it the second +2 ;)21:29
torgomaticbut like I said, no code yet21:29
mattoliveraukong: ^21:29
kongmattoliverau: thanks, feel free to ping me at irc if you have any question21:30
mattoliveraukong: cool, we share a similar timezone, so that works well ;)21:30
kongataraday_: i see ;)21:30

*** thorst has joined #openstack-meeting21:31
claygkota_: have you been following kevin & tushar on the isa-l bug?21:31
torgomaticnotmyname: true, but this lets you do it on an operation-by-operation basis... you can come up with a new bit of stuff for object PUT, then later on do something special for GET, but you don't have to tie them together with a single version number21:31
notmynamekong: you are very welcome here. you aren't disturbing anything. this meeting is for you :-)21:32
claygacoles: kota_: do we have more exposure on this isa-l rs_vand >= 5 parity thing or not?21:32
kota_clayg: is that update recently in github issue traacker?21:32
claygkota_: yeah pretty sure21:32
notmynameclayg: ah, right. thanks for bringing that up21:32
kota_i looked at it briefly but i don't think kevin and tuchar following that21:32
* kong is reading what you are saying carefully to pretend he understands everything21:33
claygkota_: I also want to get some details on urgency of lp bug #170147221:33
openstackLaunchpad bug 1701472 in OpenStack Object Storage (swift) "ring builder can converge dead state in rebalance" [Undecided,New]
*** edmondsw has joined #openstack-meeting21:33
kota_clayg: yeah, i'm still working on how it works21:33
kota_sorry i have been sick in the primary half of this week.21:34
notmynameclayg: kota_: how should we proceed on the isa-l bug? kota_ can you ping them? do we need to ignore it and let intel deal with it (that seems bad)?21:34
claygthis is the EC bad frag decode bug
claygthe heart of the issue that caused us to refuse to start swift if some isa-l policies were not deprecated21:34
notmynamekong: please don't hesitate to ask for clarity. IRC meetings are the hardest time for non-english speakers because everything goes by so quickly21:34
kongnotmyname: sure, i will. btw, for some people who don't know, we (catalyst cloud in New Zealand) have been using Swift at production since last year.21:35
*** thorst has quit IRC21:35

mattoliveraukong: also tell him to hire me ;P21:37
kongi will try my best to figure out what i can help there21:37
kongmattoliverau: hah, actually, we were talking about that in yesterday's meeting21:37
tdasilvakong: just kidding, all help is welcome and thanks for working on patch 470158, I remember Bruno saying that's very important to your customers21:38
patchbot - swift - Write-affinity aware object deletion21:38
*** edmondsw has quit IRC21:38
kongtdasilva: yes it is. after merging, i will backport it to our internal repo21:38
kongwe are using a old version of swift21:38
claygkota_: so but the ring rebalanace bug - just to understand the priority ... it is annoying ... but do you have a workaround?21:39
tdasilvakong: would be great to see someone from catalyst at the PTG21:39
claygkota_: like just increase overload or add a node or something?  i guess you can just use the any/all trick get the rings you want and ship it out - out-of-band change only!21:39
*** eharney has quit IRC21:39
* kong will ask Bruno to arrange some money for PTG :)21:39
acolesclayg: seems to be saying that there may be an issue with 4 parity frags if num data frags > 2121:40
notmynamekong: great! thanks21:40
notmynameacoles: that's what scares me21:40
kota_for rebalance, it's not super high priority but working soon is better because it looks like making dead lock state to rebalance on some cases21:40
claygkota_: I only ask because the all/any change isn't obvious to me - it seems the code did intend to do what it was saying - like it wasn't just a typo - i'm freaked out that more tests don't rub up against that condititonal?21:40
kota_i notice some ways to mitergate the dead lock by hand operation though21:40
kota_clayg: yup, changing overload or weight could help to rebalance work21:41
claygkota_: ok, tagged, torgomatic is working around lp bug #169754321:42
openstackLaunchpad bug 1697543 in OpenStack Object Storage (swift) "Ring refuses to save even when 100% parts move" [Medium,Confirmed]
kota_clayg: ok, current code is in your intention, I need to rethink the algorism because I WAS not sure if it was intended or not21:42
*** sshank has quit IRC21:42
tdasilvaacoles: not sure this is related, but found this: and this
*** cdub has quit IRC21:42
claygkota_: which is definitely a different issue - but christian pointed out that the associated change doesn't fix the ring/script in the bug - so maybe rubbing some braincells together will help21:43
kota_clayg: kk, thx. I will look at.21:44
claygkota_: yeah... it was there to prevent picking up parts from one disk and putting them back on the same server21:44
claygkota_: but... if the disks on the server are already not balanced!!!  :\21:44
*** bobh has joined #openstack-meeting21:45

*** hieulq has quit IRC21:45
kota_clayg: yeah, and my simulation with current code, in some case, the gatherd parts seems to go back to same servers as reassignment.21:45
kota_which I reported in the lp bug.21:45
tdasilvanotmyname: i'm not sure, but I definetely found interesting that they will just change the k for the user, don't allow at all21:46
claygtdasilva: acoles: notmyname: yeah I think the rules outlined in the bug report are acctually correct21:46
acolestdasilva: thanks. so that also shows cap of 32 data frags21:46
notmynametdasilva: yes. "interesting"21:46
