*** Liang has joined #openstack-meeting08:10
hyunsikyang__Yes. I also want to discuss about networking sfc08:11
takahashi-tscYes, my 1 topic is networking-sfc08:11
tpatilanother: Functional tests are failing as default VIM is not registered.08:11
takahashi-tscMy another topic is about updating wiki08:12
uehaHi all, nice to meet you. I'm Ayumu Ueha from Fujitsu.08:12
uehaI'm interested in Tacker and will be joining Tacker project.08:12
uehaThank you!08:12
yasufumhi, nice to meet you08:12
keiko-kueha hello, welcome in!08:13
tpatilueho: Welcome!!!08:13
takahashi-tscHi, welcome to Tacker08:13
yasufumOK, totally 4 topics, networking-sfc, wiki, patches, and vPTG.08:14
yasufumCould you start from the 1st one?08:14
takahashi-tscBefore discussion , can we use etherpad tfor long-term discussion?08:14
LiangHi there, this is Liang Lu from Fujitsu, same to ueha, I am also interesting in Tacker and NFV, and I am willing to join tacker project!08:14
*** jaeeeun has joined #openstack-meeting08:14
keiko-kLiang hello! welcome08:14
takahashi-tscI think we can use etherpad freely, what do you think about using above etherpad?08:15
yasufumwelcome Liang08:15
tpatilLiang: Welcome!!!08:15
hyunsikyang__What is the first topic today?08:17
hyunsikyang__Ok. takahashi, could you explain detail of networking sfc issue?08:18
takahashi-tscOK, as I write in etherpad Neutron members look for networking-sfc's volunteer.08:18
hyunsikyang__what feauter we are developing?08:20
takahashi-tscI think Tacker use networking-sfc. So I want to know that anyone want to continue to use and maintain networking-sfc.08:20
slaweqI see You are talking about networking-sfc project08:20
slaweqin general the issue with this is that we almost don't have maintaners of it08:20
slaweqso neutron cores are doing their best to keep project more or less healthy08:21
slaweqbut nothing else08:21
hyunsikyang__humm.. last time, tacker use it for SFC in openstack, and also used it for ODL integration.08:21
hyunsikyang__After that, we don't have any feature which is related with it.08:22
*** yamamoto has joined #openstack-meeting08:22
hyunsikyang__So, takahasi-tsc, They need someone to maintain it?08:23
takahashi-tscI think Neutron want to know our opinion. If no one want to maintain sfc, we should tell it to Neutron members.08:24
takahashi-tscTacker team's opinion.08:24
hyunsikyang__is it independant project now?08:24
*** yamamoto has quit IRC08:24
hyunsikyang__humm.  As a perspective of tacker, it needs for networing management.08:25
takahashi-tscNow networking-sfc is sub project of Neutron, but if no one maintain, the project move out of Neutron.08:25
hyunsikyang__what is the mean of 'the project move out of Neutron.'?08:26
*** edagawa_kc has joined #openstack-meeting08:26
hyunsikyang__just remove and remain the features?08:27
hyunsikyang__So, It means that we should find new topic and do it.. right?08:27
takahashi-tscHmm... I do not know detailed mean of "move out"...08:29
slaweqit's exactly how takahashi-tsc said, if there will be nobody who wants to maintain it, we will probably deprecate it some day and move out of stadium08:29
slaweqso it then will be in x/ namespace08:29
slaweqas unofficial project08:29
yasufumI see08:30
slaweqbut for now we didn't plan it (yet) for networking-sfc08:30
yasufumbtw, is there any deadline for making our decision?08:30
slaweqwe are doing something like that for neutron-fwaas currently08:30
slaweqyasufum: we don't have any strict deadlines08:30
slaweqbut we will review list of stadium projects during Virtual PTG08:30
hyunsikyang__OK. I also considered what is the best for it. Personally, I think it needs for tacker.08:31
slaweqand for sure we will first announce it on ML so You will have some time to do some actions if needed :)08:31
*** ttsiouts has quit IRC08:32
*** ttsiouts_ has joined #openstack-meeting08:32
yasufumOK. Unfortunately, it seems we have enough time today. We would like to continue the discussion in tacker IRC or etherpad.08:32
yasufumsorry, not enough time08:33
hyunsikyang__OK. let's move to the second noe.08:33
yasufumslaweq, I would like to share our conclusion asap08:33
yasufum2nd topic is about updating wiki, right?08:34
takahashi-tscOK,  it is simple proposal. can I update wiki as follows? and doyou have any other idea?08:35
*** ttsiouts has joined #openstack-meeting08:36
takahashi-tscMeeting/Tacker Page every week, Add URL of important docs,   Add URL of meeting etherpad page08:36
takahashi-tscAs I write on Etherpad08:36
takahashi-tscI already start to update Meeting/Tacker agenda page every week.08:37
hyunsikyang__and update member too:)08:37
takahashi-tscYes, I agree > members08:37
*** ttsiouts_ has quit IRC08:38
takahashi-tscIf you have some idea, please write in etherpad.08:38
yasufumpls confirm about “current members”?08:38
hyunsikyang__ok thanks.08:38
*** ttsiouts has quit IRC08:39
*** lpetrut_ has joined #openstack-meeting08:39
*** ttsiouts has joined #openstack-meeting08:39
tpatilCan we move to the next topic?08:41
tpatilNeed review : https://review.opendev.org/#/c/69329008:42
patchbotpatch 693290 - tacker - Support short notation for artifacts definition - 2 patch sets08:42
*** lpetrut has quit IRC08:42
tpatilIt's about adding support short notation08:42
tpatilIs it possible to merge it first in master and then back port it to stable/ussuri branch?08:43
tpatilI would like to know your opinion08:44
yasufumSorry, this review was included in my TODO, but not yet.08:45
yasufumI agree to merge08:45
yasufumand do the review soon08:45
tpatilOk, Thanks08:45
tpatilSecond point I would like to discuss is about VIM registration by tacker devstack plugin08:46
tpatilThis patch https://review.opendev.org/#/c/722209/, fixes this problem partially08:46
patchbotpatch 722209 - tacker - Fix create custom Mistral action (MERGED) - 6 patch sets08:46
tpatilbut we still see the functional tests are failing on gate job08:46
tpatilMy observation is, after devstack finishes OpenStack installation, I can register VIM successfully but somehow VIM0 is not set as default VIM by setup-default-vim role. I'm checking this problem.08:49
tpatilJust want to know if anyone else is also looking into this issue?08:49
yasufumI have not yet actually08:50
yasufumdo you have any solution for the issue?08:50
tpatilNot yet, checking the logs and trying to find out the cause. It appears that default vim is already registered so it's not allowing VIM0 to be registered.08:51
tpatilI will continue trouble shooting this issue08:52
tpatilThat's all I wanted to bring up in today's meeting. Thank you.08:53
yasufumso move on to the final topic, vPTG08:53
keiko-kI proposed this topic, but you can ignore me08:54
keiko-kI tried to ask the ether pad url and date but08:54
keiko-kI found it08:54
keiko-kLater I will add my proposal  for vPTG08:55
keiko-kto vPTG etherpad08:55
yasufumIf you have other topics today, I would like to close this meeting.08:56
yasufumand continue discussion for networking-sfc later08:56
takahashi-tscNot from me. I think we can close.08:57
yasufumok thanks08:58

ricolinThe current proposed doc architecture looks good to me15:03
jeremyfreudbergi think my patch is good, honestly i would like to merge it, and then we can improve it gradually (experts will add links explaining their work)15:04
ricolinjeremyfreudberg, sure, but I thought you would like to update some nits first?:)15:05

oneswighey guys21:01
oneswigHow's things?21:01
*** dmacpher has quit IRC21:01
jmloweDoing ok myself, you?21:02
oneswighaving a good one today.  Performance analysis, when it yields something, is fun.21:02
martiallooking into gitlab for swagger/open api usage ... maybe to create a new project for the P2302 effort21:03
*** jamesdenton has joined #openstack-meeting21:03
oneswigAs in the NIST cloud federation work?21:03
jmloweI believe I had a bit of a breakthrough today21:04
jmloweWas struggling to come up with a way to effectively use all the bandwidth to cephfs, I think using a combination of DVR, BGP dynamic routing, and IPv6 gets me there21:05
martialwell the CFRA is out, NIST SP500-33221:06
*** dmacpher has joined #openstack-meeting21:06
oneswigDoes IPV6 work with the other two jmlowe?21:06
martialright now we are looking at the IEE side21:06
*** rfolco|rover is now known as rfolco|rover|off21:06
jmloweYes, I believe it does21:06
oneswigJust checking :-)21:06
martialand we want to define a minimalistic API definition21:06
martialso OpenAPI compatible21:06
martialand open to all to contribute21:06
jmloweadded bonus is that floating ip address get the full compute node bandwidth and can bypass the network node21:07
martialso was thinking gitlab since they have an OpenAPI viewer21:07
jmlowefor ipv421:07
oneswigjmlowe: weren't you using linuxbridge on Jetstream or is this a new project?21:08
jmloweyes we are using linuxbridge, and dvr now works with linuxbridge, I'm thinking about ways to reinvent Jetstream21:09

*** rbudden has joined #openstack-meeting21:10
*** trandles has joined #openstack-meeting21:10
trandlesSorry I'm late. Prior call ran long.21:10
oneswigSounds good jmlowe.  I'm wary of DVR but perhaps that's undue21:10
rbuddenditto, hello all21:11
oneswighi trandles rbudden, glad you could make it :-)21:11
jmlowerbudden do you guys use dvr with linuxbridge?21:11
rbuddensince we’re mostly provider networks in our one cloud21:12
jmloweWith linuxbridge it's relatively simple, proxy arp and dnat in the network node network ns, compute node gets snat rules and dumps things out onto the provider network21:12
*** slaweq has quit IRC21:13
jmlowea bit of asymetric routing, throw in bgp dynamic routing and you can move the dnat to the compute node21:14
oneswigIn a parallel universe, I've been learning much about OVS hardware offloads and how to understand their dark magic.21:14
jmloweAnything useful to report from your trips to that netherworld?21:15
oneswigYes.  Don't ever go there, unless performance makes you do it :-)21:15
jmloweI've been going the opposite direction, looking at BGP as an elegant weapon for a more civilized age21:17
oneswigUsing SRIOV I'm getting line rate from the 100G NIC, but currently only one of a bonded pair attached to my OVS bridge.  OVS flow rules imply I should be using both bonded links, active-active.  The silicon's not quite on the same page, but I am so close...21:17
oneswigjmlowe: BGP to the hypervisor - cool stuff.  What do you need to do to make it work?21:18
jmloweafaik just the bgp speaker agent from neutron21:20
oneswigWhat does the network fabric look like?21:21
jmloweWell, that seems to be left as an exercise for the user21:22
*** jmasud has joined #openstack-meeting21:23
oneswig... you get your users to cable up their own networks? :-)21:23
jmloweI think you can use frrouting and vxlan to publish routes to the computes and keep the tenants non the wiser21:24
*** slaweq has joined #openstack-meeting21:25
oneswigI'd be very interested to hear how you get on with that.  The layer-2 equivalent will look like a poor country cousin once you're done21:26
oneswigI'm having an interesting MLAG issue currently, trying to get ingress traffic to use both ports instead of 95% of it coming to one port.21:28
*** slaweq has quit IRC21:30
jmlowewhich lacp mode are you using?21:33
oneswiglacp layer 3+4 - should be doing the right thing.  I wonder if the hardware hashing isn't including source IP and MAC, that might be the only uniqueness between flows.21:33
oneswigI should check, does anyone have any points to raise - agenda items, workshops, etc?21:37

jmloweNot I, still holding out hope the Berlin Summit might happen21:43
rbuddenjmlowe: +121:44
*** slaweq has quit IRC21:44
oneswigFor the ex-Vancouver PTG, we should think of those upstream activities we always wanted to do, but never had the time.21:44
trandlesI'd say something about the DOE Workflow summer seminar series but the schedule hasn't been posted yet.21:45
martialso Stig, you are looking to do RTX 2080 passthrough?21:45
trandlesEventually at https://wowoha.org21:45
oneswigmartial: asking for a friend, really.21:45
oneswigCoincidentally I think we'd just did the setup to get them working today.21:46
martialoh that's cool21:46
trandlesBig doubts that Berlin happens. Why SC20 hasn't gone virtual yet I don't know. There's about 0.1% chance I'm going anywhere near Georgia before I can get a vaccine. Plus, with COVID-19, it's worse now.21:46
martialthis is a little sad in truth21:48
jmloweI don't see how they can actually pull of a virtual SC2021:48
oneswigI don't think they even put the keynotes online from SC19 did they?  I remember looking for them some weeks later and didn't find it.21:49
trandlesNope and I even emailed the organizers asking about that. They said to keep checking back but the videos would be posted. I never found them.21:50
b1airolol trandles !21:50
oneswigperhaps someone forgot to hit record on the day :-)21:50
martialtechnology is hard21:51
oneswigAnyway, SC has some work to do to catch up with the online world.21:51
*** ociuhandu has quit IRC21:52
trandlesIt'll be interesting to see how ISC20 does online21:53
trandlesI heard mixed reviews for Red Hat's summit21:53
b1airoan unrelated question - anyone claim to be a slurm aficionado? i'm investigating consistently high "reserved time" and wondering if it is something to do with all the array jobs on this machine21:53
trandlesSounds like the system was overwhelmed somewhat21:53
*** ociuhandu has joined #openstack-meeting21:54
oneswigb1airo: not an aficionado to that degree, sorry21:54
*** ociuhandu has joined #openstack-meeting21:54
trandlesb1airo, I wouldn't saw aficionado but I can put you in touch with our slurm gurus21:54
b1airothanks trandles - i might reach out if i don't hear back from my usual suspects (one local and one at NERSC). on the other hand I could probably just submit a support ticket and then blog about it21:56
oneswigNearly at the hour - anything more to add?21:59
oneswigOK y'all, have a good day22:00
