TravT#topic:     ElasticSearch 1.x support for Newton?15:02
TravTlooks like this was discussed last week15:02
TravT#topic ES 1.x support for newton15:03
TravTi seem to be failing at meeting bot15:03
*** rainya has joined #openstack-meeting-415:03
TravTanyway, outcome was several people suggesting that we don't officially support 1.x for Newton15:04
TravTAnd there was discussion of sending to ML15:04
TravTseems like the discussion on moving devstack to ES 2.x on the ML said just do it.15:04
TravTso, maybe we should just submit that up first.15:05
TravTand see how it goes15:05
yingjun_o/15:05
sjmc7yeah, i was meant to do that, wasn’t i15:05
*** yujunz has quit IRC15:05
RickA-HPDo we have any feedback from actual cuustomers about upgrading ES to 2.X?15:05
TravTwell, from an HP distro perpsective, we know that it is going out now with ES 2.x15:06
TravTbut I don't know about others.15:06
sjmc7i’ll do it today. the blocker from an openstack perspective would be any services that rely on v115:06
TravTi don't know if the OS survey covers it15:06
*** v1k0d3n has joined #openstack-meeting-415:06
TravTsjmc7, this seems more like it should go to the operators ML15:06
*** amotoki_ has quit IRC15:06
RickA-HPsjmc7: Or more importantly, services that rely on v1 but do not realize it!15:07
TravTyeah, this is why we should upgrade devstack15:07
TravTwe still have one defect to fix in SL15:07
TravTor more correctly, get through reviews.15:08

*** rainya has quit IRC15:08
TravTi started to look at it again yesterday15:08
TravTbut didn't finish15:09
TravTso, let's get that one landed and then get devstack upgraded15:09
*** rainya has joined #openstack-meeting-415:09
TravTmaybe we can get that done by next week15:09
*** iceyao has joined #openstack-meeting-415:09
TravTi'm not sure how deprecation policy works for shared infrastructure components15:10
*** mattymo_ is now known as mattymo15:10
TravTdo we have to get all services to first declare it is deprecated?15:10
TravTdhellmann: are you around?15:10
sjmc7i don’t know how officially it’s supported15:10
sjmc7it’s only peripherally used15:11
sjmc7i don’t know of any core services that rely on it15:11
lei-zhif devstack gets upgraded, will other services using 1.x be affected15:11
*** vikram_ has joined #openstack-meeting-415:11
TravTlei-zh yes, and i think that's kind of the point of upgrading it15:11
TravTforces 2.x to get tested15:11
*** doonhammer has joined #openstack-meeting-415:12
TravToh interesting15:12
*** vikram_ has quit IRC15:12
TravThttps://review.openstack.org/#/c/320152/15:12
TravTsee Sean's comment there15:12
TravTi think that'd mean each service runs its own ES then.15:13
TravTfor devstack.15:13
david-lylethat's fine and good unless plugins require competing versions15:14
sjmc7yeah, that seems a bit weird15:14
*** iceyao has quit IRC15:14
TravTyeah, i think i'll add a comment asking about that15:14
david-lylecontainers?15:14
TravThmm15:14
TravTmaybe a kolla thing?15:14
sjmc7um15:14
TravTif they make each plugin do this15:15
TravTthen we could still pull it down.15:15
TravTbut not install it15:15
*** vikram has quit IRC15:15
sjmc7sure, but we won’t know which version we’re gonna end up with15:15
TravTjust run the script15:15
TravTand make sure we are the only ones on that port15:15
david-lyleI suppose as long as upper-constraints points to the version we care about15:16
*** coolsvap has joined #openstack-meeting-415:16
david-lylewe can say the other project is in the wrong15:16
RickA-HPHaving each service use it's own ES is good for developers, but no so much for customers.15:16
sjmc7upper constraints doesn’t deal with databases15:16
david-lyleit's in global requirements15:16
*** piet has joined #openstack-meeting-415:16
sjmc7the pytohn library’s in global-reqs15:16
david-lyleoh, that's just the library15:16
david-lyleyeah15:16
david-lylehmm15:16
sjmc7yeah. and there is a potential mismatch there also, hence why moving to 2.x only would be nice15:17
david-lyleseems like you would want a common version in openstack15:17
RickA-HPdavid-lyle: This is giving me flash backs of porting PalmOS :)15:17
TravTdavid-lyle: i agree15:17
david-lyleRickA-HP, :)15:17
david-lyleand :(15:17
TravTmaybe you can also chime in on that review15:17
sjmc7i guess from devstack’s perspective they don’t want to support every thing people decide to go off and use15:18
*** vikram_ has joined #openstack-meeting-415:18
david-lylesure, I think the counter will be that devstack is not openstack proper and that's a problem outside their scope15:18
RickA-HPWhen does something become devstack proper? How many services need to be using it?15:19
sjmc7it’s not a big deal to do it ourselves15:19
david-lyleRickA-HP, I meant devstack is not15:19
sjmc7devstack is part of infra15:19
RickA-HPOk.15:19
david-lyleso even if it's consistent in devstack, it won't be for real installations15:19
TravTRickA-HP: devstack proper kicked all but the core openstack services out awhile back15:20
TravTi think they might want to kick everything out at some point.15:20
RickA-HPHmmm15:20
TravTdavid-lyle didn't they want horizon out?15:20
sjmc7anyway - sounds like we need to get buy in from other services (of which ceilo is the onyl one i know of that use elasticsearch at all) and from deployers15:21
david-lyleTravT, I don't think so15:21
david-lylere: horizon15:21
david-lyletempest wanted us out15:21
TravTah ok15:21
sjmc7there’s only one test to kick out :)15:21
sjmc7this is drifting a little off topic15:21
david-lyledevstack as an introduction is better with a GUI15:21
david-lylesjmc7, a little?15:22
david-lyleI think we just own the es version for devstack15:22
david-lylebut research the greater openstack question?15:22
sjmc7i can’t think of any other serivces using E-S15:22
*** vikram_ has quit IRC15:22
lei-zhmonasca using elasticsearch too?15:22
david-lyleceilo15:23
sjmc7yeah, maybe monasca15:23
david-lyleunless they stopped15:23
sjmc7ceilo sort of shrugged when i asked15:23
sjmc7said “sure, go ahead, we’ll see if something breaks"15:23
sjmc7monasca supports 2.x already15:23
david-lylewe'll shrug back if it does15:23
TravTokay, i just left a comment on that review.15:24
TravTour action is to get our patches through (one mentioned above)15:24

sjmc7what specifically?15:26
sjmc7yes, that’s what broke everything15:26
TravTso that is still check experimental only, right?15:26
sjmc7it was voting, but now it’s experimental because it won’t pass15:27
TravTright15:27
TravTokay, just wanted to verify where we were.15:27

rosmaitaor problematic15:31
TravTso i used nova CLI (not specifying microversion)15:31
TravTand I tried from horizon (which I don't think specifies one)15:32
rosmaitathat should use "latest"15:32
rosmaita(if you don't specify)15:32
rosmaitaalthough i dont' really know if that's true (about the client)15:32
rosmaitasupposed to use latest if you contact api without including the version header15:33
rosmaitanova cli may pass something15:33
*** sacharya_ has quit IRC15:33
rosmaitamay have to use --debug to see what's being passed by novaclient15:33
TravTokay, i can try some more things15:33
lei-zhI thought when I first saw that patch, creating snapshot in horizon worked, I'll try to verify it tomorrow15:34
TravTlei-zh: it did for me as well15:34
TravTbut that was about a month ago15:34
TravTwith my devstack from this week, it was different15:34

*** javeriak has joined #openstack-meeting-416:09
antonymyeah, i have bunch of it put together so far for 14.04, mainly just need to test it out and then split it out for the new multi os layout16:09
*** sacharya_ has quit IRC16:10
antonymi can push up what i have so far and -1 if people want to start poking on it16:10
*** uck has joined #openstack-meeting-416:10
odyssey4meantonym yeah, I'd encourage you to try and do a daily push - both so that you don't lose any work you've done, and so that anyone interested can review and provide guidance :)16:10
antonymi had started testing it out on 14.04 with the UCA stuff but was getting some oddities, no not sure if it's just limping along on 14.04 or if i'll really need 16.04 to get it working16:11
antonymsounds good, just didn't want to cause too much noise since it's still WIP16:11
antonymthere was some overlap with some of the libvirt stuff for kvm, so i kept it split for now, but it might be more optimal to merge some of the libvirt specific stuff together16:12
odyssey4meantonym You had originally wanted to only target 16.04, so perhaps you should just run with that as the primary target first - then work out 14.04 later?16:12
spotzo?16:12
antonymodyssey4me: yeah, i had a cluster all set up on 14.04 already so i was poking that first, but yeah, i'll probably give 16.04 a try16:13
antonymi think most of it should look pretty similiar for both versions, it's really the libvirt and xen versions that matter16:13
odyssey4meantonym I started poking at the nova role yesterday and pushed https://review.openstack.org/33023116:14
*** javeriak_ has joined #openstack-meeting-416:14
antonymyeah, i was just looking at that, i'll try and line up to what you're doing16:14
odyssey4methe nova role is a bit of a mess thanks to organic growth... don't be afraid to propose patches that change the structure up to make more sense16:14
*** galstrom_zzz is now known as galstrom16:14
michaelguginonova plays for 16.04 were merged earlier this week, so it should be a good starting point16:15
antonymsounds good16:15
*** iyamahat has quit IRC16:15
*** javeriak has quit IRC16:15
odyssey4memichaelgugino yeah, thanks for that - it seems that tempest testing caused some grief there... it's part of the pain of following trunk I guess16:15
michaelguginono, it was the fact that my patchet was rebased by gerrit without me telling it to do so or indicating that it had done so16:16
michaelguginothe issue was with the patch that merged and enabled UCA by default, which is not available for 16.04 at this time.16:16
odyssey4memichaelgugino heh, yeah - I haven't yet figured out exactly when it does and doesn't rebase - I know that it definitely does in the gate queue and I think that it doesn't in the check queue16:16
michaelguginoit was failing the check queue16:17
odyssey4memichaelgugino FYI there is now UCA for Xenial, the patch I mentioned above changes that default16:17
odyssey4meUCA was published for Newton-116:17
odyssey4meanyway, thanks for persevering16:18
michaelguginono worries, I learned how to spin up tempest so it wasn't a complete waste of time16:18

odyssey4meAlright, let's move on.16:23
odyssey4me#topic Power support update16:23
odyssey4meadreznec do you have an update on progress16:23
adreznecI'm working on revising the spec for multi-arch support right now, and we have 2 environments internally we're bringing up for development there.16:24
odyssey4mesounds good - are there any blockers we can help with?16:25
adreznecWe're pursing finding replacements for the packages that aren't built for ppc64el today that aren't from the Rackspace repo16:25
odyssey4meadreznec Which packages do you mean? Apt packages?16:25
adreznecI think we're okay for now, we'll likely have more questions on details of the repo build process as we start peeling back that a bit16:26
adreznecYeah, things like percona-xtrabackup, qpress, etc16:26
odyssey4meAh OK - the non-Ubuntu things.16:26
adreznecSome thing we can pull from upstream Xenial for now, other things like qpress we're still working16:26
odyssey4meadreznec It may be a good idea to have an option to not use those external repositories as much as possible. Using those external repositories will have to remain an opt-in capability, but if we get MariaDB10 from the Ubuntu repository then that's a win.16:28
*** stevelle has joined #openstack-meeting-416:28
odyssey4meBut yeah, there will also be some other packages which are important for production (like xtrabackup) which may be harder to find.16:28
adreznecodyssey4me: Yeah, I've been working a patch for that internally to see what I can solve there.16:28
*** sdake has joined #openstack-meeting-416:28
odyssey4meWhat may have to happen is that those extras just don't deploy on Power because they aren't available.16:29
*** yamamoto has quit IRC16:29
*** ddieterly is now known as ddieterly[away]16:29
adreznecYep, at least until we can get those extras built where needed16:29
*** uck_ has joined #openstack-meeting-416:29
odyssey4meWe can then perhaps have those be an opt-in thing for deployers who want them.16:29
adreznecYeah, that would be a documentation impact for the most part16:30
odyssey4meAlso, we aren't married to the RAX mirror. If there're other mirrors which carry packages and don't have rate limits then I'm all ears. The RAX mirror usage is partially historical, but also partially because we know there are no rate limits and we got killed int he gate by that in the past.16:31
michaelguginoif you can run an x86 controller in a VM on power, or just use x86 controllers, that would work for the galera bits.16:31
adreznecodyssey4me: Good to know. I know antonym was pursuing supporting ppc64el in the Rackspace mirrors16:31
*** uck has quit IRC16:31
antonymyeah, still working on that16:31
odyssey4meAs an FYI I've requested two new mirrors from OpenStack-Infra - https://review.openstack.org/307831 (MariaDB) & https://review.openstack.org/330152 (UCA) - in order to hopefully gate more reliably using those packages.16:31
antonymthink the mirror person was out last week16:32
antonymthe power support is relevent to my interests as well :)16:32
adreznecmichaelgugino: Yeah, running the controller on x86 is the base case we're working, but we'd like both if possible16:32
adreznecantonym: Great, thanks again for checking in to that16:32

odyssey4meI'd appreciate some help keeping the etherpad up to date. Please take a look through and cross out any of the roles that are done.16:39
michaelguginoI think we should start moving the checks into the normal process as nv, instead of doing check experimental for 16.04 on the projects where the patch is complete16:39
*** yamahata has joined #openstack-meeting-416:39

odyssey4memichaelgugino yes, agreed - I'd like to move the current -nv checks to be voting for all the infrastructure roles16:40

odyssey4me#topic Ansible 2.116:48
odyssey4meThe Ansible 2.1 execution appears to be very much slower than 1.9. I haven't definitively brought it down to that as the culprit personally.16:49
odyssey4meHas anyone had a moment to figure out why we're suddenly hitting so many timeouts?16:49
odyssey4meWe've obviously added quite a bit to OSA in this and the last cycle, but the Mitaka build seems to pass just fine.16:50
odyssey4meautomagically any thoughts?16:50
automagicallyI know palendae dug in to see if dynamic inventory changes might be the culprit, but he reported that timing there was pretty consistent16:50
odyssey4mejmccrory_ ?16:50
palendaeautomagically, That and if it's affecting more than just https://review.openstack.org/#/c/325380/, it can't be that change16:50
automagicallyI’ve not personally spent any time analysing it16:50
odyssey4meI saw that stevelle picked up that rabbitmq user/vhost additions were taking around a minute each, which is super slow.16:50
jmccroryhaven't dug into it much, can spend some time looking today16:51
odyssey4meHe's put in a PoC patch to try a few things there. https://review.openstack.org/33017316:51
*** LouisF has joined #openstack-meeting-416:51
*** david-lyle has joined #openstack-meeting-416:52
stevelleodyssey4me: I'm afraid that PoC will likely be abandoned but I will spend a little more time on it first16:52
odyssey4meI'm really starting to lean towards not maintaining 1.9 compatibility for Newton if we're able to optimise more. I *really* don't want build times to get *longer* for Newton.16:52
palendaeI had thought we had some significant progress on build times dropping16:53
palendaeEvidently something's undone that16:53
odyssey4meThat said, after looking through the nova role, we're doing some very scary include nesting all over the place and I'm pretty sure that we can optimise the execution work flow a lot more while maintaining 1.9 compatibility.16:53
odyssey4mepalendae yeah, the build timeouts in the gate increased massive from 2 June16:53

odyssey4me#topic Open Discussion16:55
odyssey4meA quick intro - inc0 mrhillsman izaakk raddaoui are an OSIC team working on some stuff related to OSA.16:55
odyssey4meI'd like to ask you guys to please add an agenda item for next week to introduce yourselves, what you're doing and where you'd like help.16:56
automagicallyReally appreciate the work you guys have been doing on upgrades…16:56
michaelguginoI will be taking over the lxd integration directly.  My associate here is too busy to dive in at the moment, so I'm hoping to get that out the door in the next few weeks.  Also, I'll be writing the openstack-watcher plays along side that project, and will be sort of a cross project liason16:56
odyssey4meWe have a lot of work on the go and some of what you're doing probably relates to what pockets of other OSA members are doing, so it's important for there to be visibility and for you to use #openstack-ansible as a medium to connect with the rest of us.16:57
inc0odyssey4me, will do, first thing would obviously be upgrades L->M16:57

LouisFdoonhammer: looks like good progress is being made17:08
doonhammerI think we will need to iterate on the ovs/ovn schema some more and it would help to have some more eyes on it and try and implemetn some use cases17:08

mohankumarLouisF ,yes17:24
*** ddieterly is now known as ddieterly[away]17:24
LouisFgenerally the view is that it should get input from other projects17:24
LouisFpcarver: what is your view on how to proceed?17:24
*** ihrachys_ has quit IRC17:24
pcarverI still think it's going to be necessary but I understand there are some concerns.17:26
pcarverIt might help if we agreed on a policy on when/how to add new capabilities17:26
pcarverWe don't want to fragment by having a lot of features that are each implemented only by one driver17:27
LouisFpcarver: agree on that17:27
pcarverbut I don't know if it's reasonable to say that a feature can't be added to the API unless the L2 agent based OvS driver can do it17:27
pcarverThere will likely be things that are difficult to support without an active SDN controller17:28
pcarverAnd I'm not sure if the current "reference" implementation is going to be able to be a superset of all the SFC capabilities of all SDN controllers17:28
*** inc0 has left #openstack-meeting-417:28
*** inc0 has quit IRC17:28
LouisFhow is that handled in other projects?17:29
pcarverI'm not sure it really has been17:29
pcarverThe anti-example is networking-bgpvpn17:29
pcarverContrail supports a network VPN attachment and Nuage supports a router VPN attachment17:29
*** pvaneck has quit IRC17:30
fsunavalHow about we also define a baseline of capabilities that all drivers must support.. E.g. L3 service function, SFC in same network, etc.17:30
LouisFpcarver: what about the reference implementation?17:30
pcarverIf you try to create the opposite type of attachment that your SDN backend supports you get a not implemented exception17:30
*** messy has left #openstack-meeting-417:30
pcarverfsunaval: A baseline makes sense17:30
pcarverbut as we add features there's likely to be a first driver to support it before others17:31
LouisFfsunaval: +117:31
pcarverSo we probably need some sort of planning guideline that in order to add a new feature we need a reasonable expectation that at least N drivers will support it. I'm not sure what number N should be.17:31
LouisFpcarver: so does bgpvpn have a reference implemantation that supports all features?17:32
pcarverIt would be nice if the reference implementation could support everything, but that seems like a high bar to set17:32
*** iberezovskiy is now known as iberezovskiy|off17:32
pcarverbgpvpn does have a reference implementation but I don't remember whether it supports both attachment types17:32
LouisFpcarver: it would be worthwhile finding that out17:34
*** uck_ has quit IRC17:34
*** automagically has joined #openstack-meeting-417:34
igordcardtoo many features (big baseline) just can't live together if there are so many possible heterogeneous backends, so either one or the other in order to have a consistent, predictable API17:34
igordcardthey can't live together with the many possible backends, I mean17:35
*** dshakhray has joined #openstack-meeting-417:35
igordcardit's simply something where we will never tick all of the 3 columns in the trade-offs, unless sudenly by magic ovs, ovn, onos, odl, and others become very similar17:36
LouisFI think openstack process mandates that there is a reference implementation support all features17:37
LouisFto be able to test all features17:37
LouisFi will check on this17:39
LouisF#action Louis to check on reference implementation17:39
igordcardLouisF: I don't know if it's mandated, but it is expected that if an API is live, its operations will not fail due to backend-disparity reasons17:39
igordcardand will yield the same effect/(intent?)17:40
igordcardLouisF: nice, thanks17:40
LouisFigordcard: does "expected" mean we can document an exception?17:40
igordcardLouisF: like calling method X with Y parameter will always give Z exception? or does the exception depend on the backend?17:41

LouisF#topic dynamic chain update without service interruption17:42
LouisFwe had some discussion on this last week17:42
*** dshakhray has quit IRC17:42
LouisFi think depends on the implementation on the backend driver17:44
*** hvprash has joined #openstack-meeting-417:44
*** alexchadin has quit IRC17:44
doonhammerLouisF: I think it depends on the definition of interruption - if a flow is in process through a chain and a new chain is inserted what happens to the in-process flows?17:44
*** woodard has quit IRC17:45
LouisFthe addtion of a new chain must have no impact on traffic on any  existing chains17:45
LouisFwhat I am refering to is where a new PPG is inserted into an existing port-chain17:46
LouisFusing a port-chain-update to add/remove a PPG17:47
doonhammerLouisF: so existing flows still follow old paths, new flows go through new path ?17:47
igordcardI tested this recently and saw that all flows of the port-chain get deleted, and new ones are created17:47
mohankumaryes , i too noticed the same17:48
LouisFdoonhammer: yes17:48
igordcardand it takes something like 1 second in a simple 1-node deployment, so I suppose some packets will be dropped during that time17:48
igordcardhaven't checked if the old datapath flows stay there until the new flows are installed, though17:49
*** dshakhray has joined #openstack-meeting-417:49
LouisFigordcard: correct the current design removes the current list of PPGs and then adds the new list17:49
LouisFthis of course can be improved on17:50
*** singlethink has quit IRC17:50
LouisFby stitching in only the new PPG at the correct point17:50
mohankumarLouisF , still new folw rules has to populate , to forward traffic to new SF17:51
fsunavalLouisF/doonhammer: I am not sure we want existing flows to follow old path. After all the whole purpose of inserting/deleting a new VNF might be to avoid that in the first place.17:51
igordcardLouisF: and modifying the previous hop17:51
LouisFigordcard: correct17:52
LouisFfsunaval: the flows will be steered to the new PPG from the upstream PPG17:53
doonhammerfsunaval: might depend on the use case - if I insert a video compression VNF the stream will be corrupted. If I insert an inspection VNF everything should work fine yes?17:53
*** s3wong has quit IRC17:55
*** s3wong has joined #openstack-meeting-417:56
LouisFdoonhammer: it really depends on the implementation17:56
igordcardstate/context can be copied from one vnf to the other, but that is out of scope in networking-sfc17:56
doonhammerigordcard: yes depends on the low level networking driver17:57
LouisFif done carefully it in when a ovs rule in installed/removed at the upstream to steer to the new PPG17:57
*** SumitNaiksatam has joined #openstack-meeting-417:58
LouisFbut that is not how the current driver design works17:58
