dkushwahagongysh,  i have some points to discuss regarding heat stack05:04
gongyshdkushwaha, sure, please05:04
*** ricolin_ has quit IRC05:05
dkushwahagongysh, we are doing some PoC regarding resource reservation in Tacker05:05
*** VW has quit IRC05:05
*** slaweq has joined #openstack-meeting05:05
gongyshen05:05
dkushwahagongysh, so we are integrating Tacker-Blazor for that05:05
phuoc_dkushwaha, that sounds good05:06
dkushwahagongysh, in some cases we needs to update the heat stack, but as of now we can not update heat stack in vnf-update operation05:06
dkushwahagongysh, i want to know the approach how we can update it?05:07
*** Tom-Tom has joined #openstack-meeting05:08
gongyshdkushwaha, what do you mean the resource reservation related to heat stack.05:08
gongyshdo you have devise a way to do it in pure heat environment?05:08
gongyshcan you paste tacker-blazor url here too?05:09
*** salv-orlando has joined #openstack-meeting05:09
*** slaweq has quit IRC05:09
phuoc_dkushawaha, I think we can call e.g. heat stack update to update vnf05:10
*** yamamoto_ has quit IRC05:10
dkushwahagongysh, i am not sure, i can paste link here, as it private for now, but my team started drafting spec for that05:10
gongyshdkushwaha, to do it, the steps are: first devise a way to do in pure heat way, and then do integration on tacker. maybe we need to update tacker codes to do it.05:12
joxyukihi all, I am working tacker-blazar with dkushwaha.05:14
dkushwahagongysh, once a vnf deployed, we create reservation in blazor side, and then needs to update vnf with that reservation data. which requires update05:14
dkushwahajoxyuki, could you please explain05:14
*** salv-orlando has quit IRC05:15
joxyukiyes, to create a VM using reserved resource, heat stack need to know reservation-id in HOT.05:15
gongyshjoxyuki, that's good.05:16
joxyukigongysh, what do you mean "device" exactly?05:16
gongyshdevice is old term for vnf?05:16
gongyshdevice is old term for vnf.05:17
joxyukii see, thax05:17
joxyukithanks05:17
gongyshpreviously, tacker is service vm manager.05:17
gongyshjoxyuki, so you seq is: vnfm -> nfvo: reserve resource05:18
gongyshvnfm -> instantiate vnf with reservation id.05:18
joxyukigyngysh, no.05:19
dkushwahajoxyuki, sorry for interrupting, but i think you interpreting  "devise" as "device"05:20
*** coolsvap has joined #openstack-meeting05:20
joxyuki1) user-> tacker: vnf-create, 2) user -> blazar: reservation, 3) user->tacker: input reservation-id05:21
joxyukiyes, devise -> device05:21
gongyshjoxyuki, 1) user -> tacker: vnf-create will create vms on target openstack, why do you still need to do 2)?05:22
*** phuoc_ has quit IRC05:22
gongyshI think the sequence is to be: a) user -> blazar: reservation b) user-> tacker: vnf-create with reservation-id05:23
joxyukigongysh, could you see https://youtu.be/a1loFExpjb0 ? this is our use case.05:24
gongyshjoxyuki, ok, I will have a look05:25
*** VW has joined #openstack-meeting05:25

oneswig#link there isn't an agenda as such https://wiki.openstack.org/wiki/Scientific_SIG#IRC_Meeting_December_20th_201711:01
armstrongThanks and same to you11:01
*** edmondsw has quit IRC11:01
oneswigHey armstrong have you moved timezones?  Thought you were in Canada...11:01
armstrongYes I am still in Canada11:02
armstrongI missed the meeting yesterday11:02
oneswigWas it Ontario?11:03
oneswigOICR?11:03
armstrongI am in Montréal11:05
oneswigHave you completed your PhD?11:06
*** krtaylor has joined #openstack-meeting11:06
armstrongNo not yet11:06
*** rossella_s has quit IRC11:06
oneswigHow's the research going?11:07
armstrongSo far so good11:07
*** rossella_s has joined #openstack-meeting11:07
*** yamamoto_ has joined #openstack-meeting11:08
oneswigIt's on private cloud infrastructure, right?  What are you looking at?11:08
armstrongLive migration11:08
oneswigInteresting.  Live migration in research computing or more generally?11:09
armstrongResearch computing11:09
*** yamamoto has quit IRC11:11
oneswigWhat are you finding so far?11:11
*** gcb has quit IRC11:12
oneswigLive migration doesn't come into the workloads I typically see, but certainly does come into the supporting components deployed around it - web APIs, house keeping activities, jenkins instances etc.11:15
armstrongBased on my last presentation @Sydney, I want to add different VMM, because so far only KVM and Xen were considered11:16
oneswigI hadn't seen this presentation - got a link to it?11:16
armstrongIt’s in the link of the Tuesday’s presentation we had11:19
oneswigarmstrong: what other VMM is there?11:19
armstrongVMware etc.11:19
armstrongThere are five or so supported by OpenStack11:20
oneswigAh OK, got it.11:20
*** reedip has quit IRC11:21
oneswigarmstrong: are there findings you'd like to share some time in a Americas-timezone meeting?11:22
armstrongOk11:23
*** priteau has joined #openstack-meeting11:24
oneswigarmstrong: if you're interested in doing that11:26
armstrongSure oneswig, I am interested11:27
oneswigLet me know when you would like to do that, we can put it on the agenda.11:27
armstrongOk good11:28
*** rossella_s has quit IRC11:29
oneswigI've been planning for 2018 to bring in some of the discussions that have been going on with the team at CERN, around developing OpenStack's support for research computing11:29
*** caboucha has joined #openstack-meeting11:30
*** andreas__ has joined #openstack-meeting11:30
armstrongThat is interesting11:30
armstrongCERN uses OpenStack ?11:31
oneswigyes, quite a lot :-)11:31
*** neiljerram has joined #openstack-meeting11:31
*** andreas__ has quit IRC11:31
ildikovoneswig: I have a quick question when we get to the open discussion part :)11:31
oneswigildikov: there are no other kinds of discussion today - we are taking it easy :-)11:32
ildikovoneswig: coolio :)11:32
oneswigfire away11:32
*** rossella_s has joined #openstack-meeting11:32
ildikovoneswig: just wanted to ask whether the scientific SIG would be interested in occupying a few slots at the PTG ?11:33
*** andreas_s has quit IRC11:33
oneswigFor development work?11:33
*** alexchadin has quit IRC11:33
ildikovoneswig: Technical discussions or even development work11:34
*** reedip has joined #openstack-meeting11:35
ildikovoneswig: we're providing space for working groups/SIG at the beginning of the week and thought to ask whether there's interest from you guys11:35
oneswigI don't know how many active SIG members will be in Dublin but I'm assuming a few will be attending.  From our firm, probably 3-4 (ie, half the company :-)11:35
ildikov:)11:36
ildikovWould you like to have dedicated slots or rather joining project discussions and other sessions?11:36
oneswigildikov: can you explain the difference from the forum?11:37
ildikovoneswig: most of the attendees are developers and we're focusing on planning for the upcoming cycle and any other more technical discussions11:38
oneswigildikov: it's hard to know.  If the forum's about communicating needs and pain points, what input is needed at the PTG - more of the same?11:38
ildikovWhile the forum is more about gathering the user, operator and developer communities for feedback and a bit higher level chats11:39
oneswigMy first thought is to sit in on project meetings rather than have dedicated slots, but that's going to be happening anyway.11:39
*** alexchadin has joined #openstack-meeting11:39
*** psachin has joined #openstack-meeting11:39
oneswigildikov: if there was a dedicate slot for the scientific sig, how would you like to see it used?11:40
ildikovPTG would be about to figure out how to address the pain points11:40
*** oidgar has quit IRC11:40
armstrongIIdikov: when is the PTG coming up?11:40
ildikovoneswig: how to use it is on the group really11:41
ildikovoneswig: it's not a must rather than an offer to think about whether you can utilize it as a group11:41
oneswigildikov: when do you need to know?11:42
ildikovoneswig: you can use to have discussions around some items you would like get addressed and have devs in the room as well11:42
ildikovoneswig: sooner rather than later, will ask my colleague who's organizing the slots11:43
oneswigI can imagine it being useful in various ways - agreed.  I think it may come down to whether some of the key SIG members involved are planning to go to Dublin11:43
ildikovarmstrong: it's the week of February 26th11:43
ildikovoneswig: yeah, it's definitely more useful if you have a reasonable coverage from the team11:44
oneswigI shall enquire...11:44
armstrongiIdikov: thanks, I will like to attend11:44
ildikovoneswig: there are also options to occupy a half day or a full, etc11:44
ildikovarmstrong: awesome!11:44
ildikovarmstrong: https://www.openstack.org/ptg/11:45
ildikovarmstrong: let me know if you have any questions11:46
oneswighalf-day tops, I think.  Can't expect anyone to listen for longer than that11:46
armstrongiIdikov: ok I will let you know. Thanks 😃11:46
ildikovoneswig: ok, I will let Kendall know and will check back on deadlines11:47
ildikovoneswig: BTW, I will attend RCUK in January11:48
oneswigildikov: and I'll ask around for likely attendees.  I think if we have enough, there will be a critical mass.11:48
oneswigRCUK: excellent - are you presenting?11:48
oneswigI will be and I believe the Tuba Guy will be too :-)11:48
oneswigOr at least, taking part.11:48
ildikovoneswig: yep a short one on the Passport program and a bit on ORC11:49
*** alexchadin has quit IRC11:49
oneswigOh nice.  I'd be interested in the passport program11:49
ildikovoneswig: coolio11:49
oneswigNot seen a presentation on that yet11:49
ildikovoneswig: are you aware of any other happening that week in London that's OpenStack related?11:50
ildikovoneswig: I think there was on the Summit, will look for links when I'm back to my laptop11:50
oneswigCommunity events, no.  But I think the London OpenStack is overdue another meetup, and I can nudge Darryl.11:51
oneswigThanks ildikov - don't worry I think I can find it11:51
oneswig#link https://www.openstack.org/videos/sydney-2017/wings-to-roam-any-cloud-join-the-openstack-global-passport-program-today11:52
ildikovoneswig: thanks11:52
ildikovoneswig: yep, that should be the one11:52
oneswigarmstrong I looked for your summit presentation but didn't find it11:52
armstrongiIdikov: is the PTG a sponsored program?11:53
armstrongoneswig: really?11:53
ildikovarmstrong: you whether the event itself is sponsored by companies?11:54
armstrongImmediately after I did the presentation, I submitted the link to the slides and works11:54
*** rossella_s has quit IRC11:55
armstrongiIdikov: yes is it sponsored by OpenStack11:55
armstrong?11:55
ildikovarmstrong: it is an OpenStack event organized by the Foundation11:55
*** oidgar has joined #openstack-meeting11:56
armstrongIIdikov: Ok thanks, I asked because I saw something like $100 registration at Eventbrite :)11:57
ildikovarmstrong: yes, it has a registration fee11:58
armstrongoneswig: where you not in the hall on Tuesday? When we were presenting? I think I was the last to pressent that day11:58
*** rossella_s has joined #openstack-meeting11:58
ildikovarmstrong: I can ask whether we have the travel support program still open for this one if you need it11:58
oneswigarmstrong: Ah, at the scientific-SIG lightning talks?  Now I'm with you.11:59
armstrongIIdikov: yes please I will need it thanks11:59
oneswigThought there was something more involved in the summit schedule.11:59
*** salv-orl_ has joined #openstack-meeting11:59
ildikovarmstrong: will get back to you on this when I got the info from my colleagues12:00
*** unicell has joined #openstack-meeting12:00

oneswigWe are out of time, that crept up12:01

ad_rien_So msimonin kgiusti please15:24
kgiustiSo we've been meeting weekly to discuss the oslo.messaging testing15:25
kgiustiLast we talked msimonin and avankemp were still testing small distributions under rabbit15:25
kgiustiWe're getting together tomorrow for an update.15:26
ad_rien_ok thanks15:27
kgiustimsimonin: avankemp anything I missed?15:27
msimoninThat's perfect :)15:27
avankempnop, maybe I can just add that we're scaling the experiments now to thousands of agents15:27
kgiustiexcellent!15:27
msimonin+115:27
ad_rien_+115:28
ad_rien_msimonin:  you put a couple of questions on the etherpad. Do you want to go through please?15:28
msimoninoh yes sure15:28
msimoninespecially if we have kgiusti and oanson15:28
msimoninit's related to oslo.messaging and dragonflow15:29
kgiusti\o/15:29
ad_rien_please15:29
ad_rien_:D15:29
*** Apoorva has joined #openstack-meeting15:29
msimoninlast time oanson told us that the pub/sub implementation of dragonflow was plugable15:29
oansonYes15:29
msimoninbut there was no plugin for oslo.messaging15:30
oansonI was just reading through the question in the agenda.15:30
msimoninok15:30
msimonin:)15:30
oansonI don't know oslo.messaging too well15:30
kgiustiI don't believe I've worked with dragonflow - is there a good website describing it?15:30
kgiusti(save me the google fu)15:30
oansonWe have a blog, but mostly it's just us for now :)15:30
msimonin(you should use qwant :) )15:30
oansonEspecially for technical details15:30
kgiustioanson: I recommend you keep it that way.15:30
kgiustioanson: oslo.messaging that is ;)15:30
oansonxD15:31
kgiustiSo from the epad is the Q if an oslo.messaging plug in to dragonflow available?15:31
kgiustiNot that I'm aware of.15:31
oansonCurrently there's no oslo.messaging driver.15:31
msimoninyes15:31
oansonIt would be a great contribution, but we don't have the resources to do it. Especially since we have 2-3 other drivers already working well15:32
msimoninthe point is what would be missing in oslo messaging (or not)15:32
kgiustimsimonin: in terms of dragonflow messaging requirements?15:32
oansonI doubt there's anything missing. Dragonflow only needs a way to send a message, be notified when a message is received15:32
kgiustimsimonin: like topic subscriptions?15:32
msimoninI don't know if line 1665 to l1667 are clear enough for example15:32
oansonThere is also the ability to subscribe to topics15:32
msimoninare those topics dynamics ?15:33
oansonYes15:33
oansonCurrently we have a global topic that every one registers to. And a topic per tenant/project15:33
msimonindo you have a topic per sec-group for example ?15:33
oansonNot currently.15:33
msimoninthat an agent would subscribe to if needed15:34
oansonBut our agent is an all-or-nothing15:34
msimoninah ?15:34
msimoninwhat do you mean ?15:34
oansonWe have a single agent that does everything:15:34
oansonThe Dragonflow controller runs on each compute node.15:34
oansonIt connects to the OVS switch, and implements everything it can through that15:35
*** yamamoto has quit IRC15:35
oansonWhat it does is defined by the applications that were loaded15:35
oansonSo the Dragonflow controller (our single agent) subscribes (using the pub/sub mechanism) to events according to specific tenants/projects15:35
oansonIf selective proactive is enabled, only the tenants installed on it (i.e. ports bound to this node). Otherwise, it subscribes to everything.15:36
oansonmsimonin, this was a bit long. Does it answer your question?15:36
msimoninIf a sec-group is modified, are all the agents notified ?15:37
oansonIn general, yes15:37
msimonineven if they aren't interrested in this secgroup15:37
msimonin?15:37
oansonYes15:37
oansonBasically, we can filter this on the tenant level - if the node doesn't have any tenant ports installed, it won't get the event.15:37
msimoninso in a massively distributed clouds this would make a big multicast ?15:38
oansonBut all nodes with ports belonging to the tenant (or project) will get the event15:38
oansonYes.15:38
oansonWe trust the publish subscribe mechanism to be light enough.15:38
msimoninand reliable enough ?15:39
oansonNo. We verify we're up-to-date by syncing with the database15:40
oansonI think the sync time is configurable15:40
msimoninif an agent miss some messages, it detects it and resync with the db ?15:40
oansonYes15:40
*** trozet has quit IRC15:40
msimoninI think this would be a good exercice to check if oslo messaging could be a plugin.15:41
kgiustioanson: msimonin: I can do that15:41
oansonThat would be great!15:42
kgiustihopefully by next meeting, but no promises (will *try* to limit the egg nog)15:42
ad_rien_sorry15:42
msimoninkgiusti: if there anything I can do to help ?15:42
oansonkgiusti, I am available for any help you need15:42
ad_rien_I've been preempted15:42
*** slaweq has quit IRC15:43
msimoninI'm interesting in the topic and this sounds related to the experiments we are planning to do15:43
kgiustimsimonin: did you want to do the evaluation?  I didn't mean to rush in15:43
msimoninregarding the massively distributed RPCs15:43
*** trozet has joined #openstack-meeting15:43
ad_rien_Guys may I ask you to take some notes on the pad just to have an overview of what you discuss? races for the other15:43
ad_rien_s/race for the other/ /15:43
kgiustiad_rien_: yep - happy holidays + new year to you!15:44
msimoninkgiusti: not I'm interested but since I don't know at all the oslo_messaging internals I don't think I am the best candidate15:44
*** armax has joined #openstack-meeting15:44
kgiustimsimonin: let me take a quick pass through then we can plan work if that is the next logical step.15:44
*** iyamahat has joined #openstack-meeting15:44
msimoninkgiusti: ack :)15:44
ad_rien_(kgiusti I'm back now, have been preempted for the last couple of minutes)15:45
*** iyamahat has quit IRC15:45
ad_rien_Can we move to the other topic15:45
ad_rien_?15:45
msimoninshould we put an action ?15:45
kgiustioanson: if you can send me some pointers where I can start ramp up on dragonflow + drivers (kgiusti@gmail.com) that'd be great15:45
*** iyamahat has joined #openstack-meeting15:45
kgiustimsimonin: I'll do that15:45
oansonkgiusti, sure. I'll do that!15:45
ad_rien_Actually, I would like to start preparing the PGT meeting as I think it is important to come with foods for core-devs discussions15:46
ad_rien_?15:46
kgiustigo for it - I'm all set!15:46
ad_rien_can we switch or you have a last point to discuss ?15:46
kgiustiswitch ok!15:47

*** avankemp has quit IRC15:47

ad_rien_oanson:  msimonin ok for you too?15:47
msimoninyes15:47
oansonSure15:47
ad_rien_thanks15:47
ad_rien_So I propose to jump over the two last items regarding the on-going actions as we did not make significant progress and I propose to discuss the PTG topic ;)15:48
ad_rien_#topic PTG-Preparation15:48
*** openstack changes topic to "PTG-Preparation (Meeting topic: massively-distributed-clouds)"15:48
ad_rien_so my goal is to try to prepare as much as possible the PTG15:49
*** eharney has quit IRC15:49
ad_rien_I would like to propose to work in subgroups15:49
msimoninWhat will be the format ?15:49
ad_rien_in order to collect as much as possible informations regarding the code base15:49
*** yanxingan has joined #openstack-meeting15:49
ad_rien_format will be the one we want to have15:49
ad_rien_I think there will be at least one sessions regarding the use-cases15:50
msimoninOh :)15:50
ad_rien_but because I know that we can discuss about use-cases during three days without diving into details15:50
ad_rien_I think it is important to come with more concrete stuffs15:50
ad_rien_for instance an etherpad with three identified use-cases15:50
ad_rien_and then conduct a gap analysis of the current code-base w.r.t. these use-cases15:51
ad_rien_So If we can define some milestones just to help us to move forward and be sure we will have enough materials before the PTG15:51
ad_rien_I think it would be great15:51
ad_rien_right now we have one use-case15:51
*** pcaruana has joined #openstack-meeting15:51
ad_rien_i.e. control plane is centralized and we have remote nodes15:52
ad_rien_vCPE/SDN/...15:52
*** donghao has quit IRC15:52
ad_rien_use-cases15:52
ad_rien_we can also think about using the cells15:52
ad_rien_what are the pros/cons of such an approcha?15:52
ad_rien_using the regions what are the pros/cons15:52
ad_rien_etc...15:52
ad_rien_for each try to see whether we need additional piece of code15:52
ad_rien_of if we can just revise the current code bas15:53
ad_rien_e15:53
ad_rien_or if we should really fork the code in order to propose another implementation/alternative of a particular service15:53
*** coolsvap has joined #openstack-meeting15:53
ad_rien_(e.g. DragonFlow in comparison to the vanilla neutron implementation).15:53
*** janki has quit IRC15:53
ad_rien_so far so good?15:53
ad_rien_Any remarks/other ideas ?15:53
*** felipemonteiro has joined #openstack-meeting15:54
ad_rien_no remark :-P ?15:55
msimoninUsage of pub/sub in the context of massively distributed deployment ?15:55
msimonin:)15:55
msimonin(I'm biased)15:55
ad_rien_from my view point this is interesting but probably a bit too specific15:55
ad_rien_The goal from my viewpoint is to be able to discuss with the core developpers15:55
ad_rien_core developpers will be focused on the code base15:55
ad_rien_if we arrive with ''just'' another solution without any strong arguments against the current code base, I think our viewpoints will not be considered?15:56
ad_rien_but it can be a topic indeed15:56
ad_rien_How can core-services can communicate WANWide with intermittent network connectivity15:56
ad_rien_Can you add it into the pad15:56
msimoninyep15:56

*** jamesmcarthur has quit IRC15:57
ad_rien_but the same we need to come with some materials15:57
oansonad_rien_, sure.15:58

ad_rien_it would be nice15:58
*** jamesmcarthur has joined #openstack-meeting15:58
*** guhcampos has quit IRC15:58

ad_rien_ok thanks guy15:58
ad_rien_please put some notes into the pad15:58
ad_rien_nothing else from my side15:58

smcginnisjungleboyj: I believe it's on the host exposing the LV.16:17
smcginnisAnd the iSCSI targets it presents.16:17
jungleboyjOh ....16:17
smcginnisThe paste included in the bug seems to indicate a difference, but not sure if that's really what the nova host sees.16:17
jungleboyjYeah, I see that now.16:17
smcginnisThough maybe I'm wrong about having test coverage here. I should double check that.16:18
*** andreas_s has quit IRC16:18
jungleboyjI am not totally sure that we do.16:18
smcginnisIf no one has any background on this, that's OK. Just thought I would raise it in case someone knew something about it.16:18
smcginnisSeems easy enough to add the call they mention in the bug.16:18
jungleboyjsmcginnis:  It sounds like it may be a valid but.  I think with the extend in-use we had thought that there might be a driver impact and it just didn't get followed up upon.16:20
*** yanxingan has quit IRC16:20
jungleboyjNo one is jumping up and down with input.16:20
smcginnisjungleboyj: Yeah, I suppose. We can move on. Doesn't sound like anyone knows this bit. :)16:20
*** yanxingan has joined #openstack-meeting16:20
jungleboyjsmcginnis:  I would think that eharney or hemna might have input.16:21
*** edmondsw has joined #openstack-meeting16:21
jungleboyjThey seem to know something about iSCSI.  :-)16:21
smcginnisMaybe they'll chime in later.16:21
jungleboyjsmcginnis:  Are you going to follow through with the bug then?16:21
smcginnisjungleboyj: If no one else grabs it before me I can. Need to wrap up a couple other things first.16:22

*** yanxingan has joined #openstack-meeting16:25
*** edmondsw has quit IRC16:26
ildikovI think we're mainly in an agreement on the points though, so maybe on the meeting tomorrow the latest someone can update it if jgriffith will not do it by then16:26
smcginnisGood plan.16:26
*** felipemonteiro has quit IRC16:26
jungleboyjAgreed.  I will review before tomorrow's meeting.  If we are all in agreement and if John can't get to it I can do an update.16:26

*** andreas_s has quit IRC16:32
smcginnisWe need reviews on those patches as well.16:32
smcginnisThere's not a ton out there, but they haven't been getting much attention lately.16:32
smcginnisThat's it, just wanted to give that public service announcement.16:32
jungleboyjsmcginnis: Thank you.  Good point.16:33
jungleboyjsmcginnis:  I need to add cinder-tempest-plugin to my list of things I get e-mail for.16:33
* jungleboyj also needs to clean out my review inbox.16:34
*** kgiusti has left #openstack-meeting16:34
smcginnisOh, on that point too, make sure we don't add any more tempest tests to the cinder repo. They should be going in the new repo now.16:34
smcginnisI have a patch to remove the cinder tests, but I think that's still out there.16:35
*** Exhar has joined #openstack-meeting16:35
jungleboyjsmcginnis:  If you point me to that patch we can try to get it through.16:35

*** yanxingan has joined #openstack-meeting19:00
*** Zara has joined #openstack-meeting19:01
SotKso since the last meeting I started working on a patch to implement the ability to link to a partially-filled new story form19:01
Zarao/ my clock is 2 min behind =D19:02
SotKwith support for forcing the created story to be private too19:02
SotK:D welcome19:02
Zarathank you! I have an enormous review backlog now19:02
SotK#link https://review.openstack.org/#/c/526219/19:02
SotKthat is the current WIP19:02
* fungi is late19:02
diablo_rojoSotK, awesome! Will check it out.19:02
SotKit doesn't actually work fully yet, I've not had much chance to improve it since last week19:03
* SotK suddenly remembered that christmas is a thing that needs preparation19:03
fungii got to thinking about the implementation there, and i feel like it's not only a big piece of the vmt and docs need, but also goes a long way towards the more general bug reporting solution i've been hearing everyone say they want19:03
*** ad_rien_ has joined #openstack-meeting19:04
SotKyeah, I'm hopeful it will be helpful for that19:04
SotKsince it'll allow people to create links with project-specific "bug templates" for example19:05
*** unicell has joined #openstack-meeting19:05
Zara\o/19:05
diablo_rojo\o/19:05
fungiif nothing else, i think some careful application of custom reporting urls solves the "i want to report a bug, not a story" confusion19:06
Zarayes19:06
*** unicell1 has joined #openstack-meeting19:06
Zaraor even 'I want to make a bug' :D19:06
fungithough i really liked in the infra meeting yesterday when jeblair said (paraphrasing because i don't feel like looking it back up) "a bug is just a sad story"19:06
fungior maybe that was in the zuul meeting19:07
* fungi has pre-holiday brain fog19:07
persiaI think that was infra: I think it's true, but helping folk understand that by providing custom forms is likely to be a good thng.19:07
ZaraI only realised today that I'd lost my connection to #openstack-meeting19:07
ZaraI thought it was quiet19:07
diablo_rojoAgreed. Comically difficult for people to understand that bugs and new features are both just code changes.19:08
* fungi has been trying to refer to storyboard as "defect and task tracking"19:08
*** jamesmcarthur has joined #openstack-meeting19:09
persiaPerhaps more consumable than "a tool for communicating desire and intent"19:09
*** unicell has quit IRC19:09
fungiwhile most people ultimately need a task tracking system, they're operating under the assumption that what they want is a defect tracking system19:10
Zarahttps://storyboard.openstack.org/#!/page/about has our current blurb fwiw19:10
*** yanxingan has quit IRC19:10
Zarait mentions bugs as a subset of stories19:10
Zarawell, bug reports19:10
fungioh, thanks! i'd forgotten that existed. i'll try to remember to link it more often19:10
Zarait should be the page that comes up by default when someone navigates to sb but isn't logged in iirc19:11
SotKit is :)19:11
Zaraso that new users know what is19:11
*** oidgar has joined #openstack-meeting19:11
fungiexcellent. i just never see it because i'm always following deeper links into teh webclient19:11

SotKthanks btw :)19:16
fungi+2, looks like a pretty simple change19:16
fungialso note that mordred has pushed up a largeish (i think, haven't looked yet) webclient patch to switch up the framework a bit19:17
SotKyeah, I'm looking forward to trying that out19:17
fungi#link https://review.openstack.org/52843619:17
SotKit'll be good to get our tooling up to date, thanks mordred19:18
fungimaybe he'll reciprocate with some reviewing other webclient changes19:18
diablo_rojoOh sweet. Then I am actually kind of on top of things.19:18
*** salv-orlando has quit IRC19:19
SotKhave there been any developments in the launchpad migration since last meeting?19:20
*** bobh has quit IRC19:20
Zara(thanks for the links. I'm the one slowing down reviews atm I think.)19:21
Zara(have had holidays and things, am around more now)19:21

SotKZara: whilst you're looking, there is also https://review.openstack.org/#/c/307712/ and https://review.openstack.org/#/c/510669/ of mine that are waiting on reviews :)19:22
Zarayeahhhh19:22

Zaramaybe won't get to everything but do want that markdown parser change in asap19:23
*** yanxingan has quit IRC19:25

*** jamesmcarthur has joined #openstack-meeting19:26
SotKexcellent :D19:26
fungiit'll be nice to modernize, thanks again mordred!19:26
persiamordred: 5K lines is small?19:26
mordredpersia: in this case - yes19:27
fungiat least most of that is generated code19:27
fungiyay javascript19:28
mordredpersia: (the yarn.lock is an auto-generated file - package.json is where the important bits are)19:28
persiaNearly all of it: the actual patch is mostly deleting stuff that shouldn't be used anymore, with a couple minor adjustments in pathnames as a result.19:28

notmynamea few things to review and a new topic from m_kazuhiro21:03
notmynamefirst up, some FYI stuff...21:03
notmyname#topic general stuff21:04
*** openstack changes topic to "general stuff (Meeting topic: swift)"21:04
notmynamepatch 528582 is making its way through the gate21:04
patchbothttps://review.openstack.org/#/c/528582/ - swift - Native Zuul v3 tox jobs21:04
*** diablo_rojo has quit IRC21:04
notmynameand in fact it changes the gate21:04
*** priteau has joined #openstack-meeting21:04
notmynameit's the in-repo definition of check and gate jobs for swift21:04
notmynameusing the new zuul v3 stuff21:04
notmynameit's a great improvement because it allows us to define test jobs in our own repo (AIUI, even with ansible scripts to set up an environment, if needed)21:05
notmynamethis first patch is the last step int he old centralized job definition to the new zuul v3 way21:06
claygtdasilva: ^^^ pretty cool huh!?21:06
claygall hail zuul v321:06
tdasilvavery! was thinking we could add libec, probe tests21:06
notmynameyup21:06
clayg~ a whole new world ~21:06
kota_+121:06
joeljwright:)21:06
notmynamespeaking of probe tests, we all probably noticed by now that the swiftstack community qa cluster has been throwing errors. I've finally burned through enough on my todo list to get to that item21:07
claygburn it down!21:07
notmyname(1) I hope to fix it, of find someone who can (2) some of it may not be needed any more with the zull v3 definitions21:07
notmynameany other general stuff to bring up?21:08
claygoh... i mean fix it... but you COULD burn it down - that would *also* be fun...21:08
notmynameI thought I had something else, but of course I didn't write it down...21:08
timburkei was actually thinking of that wrt to the func tests...21:08
kota_i think, libec and pyeclib are also in progress for zuul v321:08
claygtimburke: yeah burn 'em!21:08
notmynameI heard something about some conference talks being accepted, acoles cschwede, tdasilva21:08
timburkewe should totally get some cross-policy testing happening in the gate though!21:08

m_kazuhiroThis is updating work for expirer's task queue and this is next work for auto-tiering.21:28

rledisez+1 very good summary of discussion we had in sidney21:32
notmynameis there a particular question that we need to discuss in this meeting?21:33
notmynamelooks like it will be a very good topic in dublin21:33
tdasilvaRomain Expirer Algorithm21:34
*** bobh has joined #openstack-meeting21:34
*** rajulk has joined #openstack-meeting21:34
tdasilvayay, swift finally has named an algorithm21:34
claygneat idea to use partitions to break up work...21:34
notmynameheh21:34
m_kazuhiroToday's main discussion topic is in end of the google doc.21:35
m_kazuhiro"Known problems"21:35
*** bnemec has quit IRC21:36
claygm_kazuhiro: can you restate that problem - i don't understand it in that context... I read something about a migration?  maybe taking the old containers and backfilling into the new per-partition containers?21:36
rledisezbasically, if every objects server fetch a different account for object-expiring tasks, what about the legacy tasks. all objects servers will fetch the same account. if you have a lot of object server, it's a DDoS of the account server21:37
rledisezmigration could be difficult path if you have hundreds of millions of tasks21:37
claygrledisez: i agree - i'd rather now have to translate the rows21:38
torgomaticshard the migration work with the new queue system21:38
m_kazuhirorledisez: Thanks21:38
*** cleong has quit IRC21:38
torgomatic(half serious :) )21:38
*** rmcall has quit IRC21:38
*** bobh has quit IRC21:38
claygrledisez: how many object-expirier's do you currently run?  You're worried about a bunch of account GETs ... i... I'm not sure I'm scared... once it's in the page cache... I'm not sure21:39
clayglike... what... 10K requests?  meh..21:39
timburkecould we have some config option that says "continue pulling work from the old location, but write new work down in two places" then later flip it to "pull work from new place (and only write down new work in one place)"?21:39
rledisez10K requests, every minutes ?21:39
rledisezthat's a lot, I already killed a cluster that way21:39
tdasilvatimburke: i was about to propose something like object-expirer221:40
rledisezi was thinking of something based on the device id and current day. a process would fetch task if day % device_id == 0 not that great, but it would limit the concurrency on legacy account21:40
rledisezwell, it's actually a very bad ideai, forget it :)21:42
*** bobh has joined #openstack-meeting21:42
m_kazuhiroI got an idea about that from kota_... and I think it is great. The idea is that expirer has "check_legacy_queue" boolean configure. We can controll expirer count which checks legacy queue with the value.21:43
notmynamem_kazuhiro: does that answer help you move forward for now?21:44
rledisezi'd rather have something the operator does not need to think about. if the operator forget that new param, the feature is broken. doesn't feel nice. but as we require that the operator run object-expirer on object-server, it might be OK I guess21:44
m_kazuhironotmyname: Yes. I can move forward with the answer. But I want to get opinions about the idea.21:46
*** ykatabam has joined #openstack-meeting21:46
*** yanxingan has joined #openstack-meeting21:46
claygrledisez: so you HAVE deployed enough object-expirers that the container server's holding the .expiring_objects account were not happy with the current amount of listings?  I don't think i've ever had that problem.21:46
clayger... account servers or account/container servers21:47
rledisezclayg: it was not object-expirer, but an other internal process working pretty much the same way AFAIR21:47
claygI've seen specific expiring_object/<timeslice> *containers* get busy (but that's because they're eating row updates)21:47
*** bobh has quit IRC21:47
claygand that part at least has been better since the RAX guys did the thing to make 100 containers for every timeslice or however dfg wrote it21:48
rledisezmaybe i should do an other test on our biggest cluster to see how it behave now21:48
timburkei feel like i must be missing something... probably need to read about it more. but the migration path for inherently ephemeral data seems like it shouldn't be a stumbling block. is it that we're changing the cardinality of workers?21:48
claygdoes the new design have a bunch of accounts?  I thought it was account-per-task so I don't quite follow how the load at the account layer is reduced ... and I'm not sure how many GETs on account would need to happen before I'd be concerned...21:49
rledisezclayg: account per $task-$ring-$partition_number21:50
claygI mean... i think we can write these processes to be pretty nice to swift - and we'll only have as many clients as nodes.. and there's probably more external clients than internal nodes...21:50
claygORLY!?  ok then...21:50
*** ijw has quit IRC21:50
*** priteau has joined #openstack-meeting21:51
claygok, yeah I minunderstood the diagram - the indentation is account -> container -> object - gotcha21:51
claygok cool!21:51
torgomaticas long as we don't wind up with some Kafka-esque rules for how our queue system works, things should be fine21:51

*** tlam_ has quit IRC21:53

claygthis problem at least21:55
