nick-maok09:12
gsagienick-ma: the stage is yours09:12
nick-mai uploaded the source code that I wrote last several days and updated the spec to reflect the design.09:12
nick-mathe current code is under manual testing.09:13
dingbooptOnly version number, no jounal db table?09:13
gsagie#info DB consistency patch https://review.openstack.org/#/c/282290/09:13
nick-maversion number and SQL lock db table.09:14
gsagie#info DB consistency spec https://review.openstack.org/#/c/268005/09:14
*** raofei has joined #openstack-meeting-409:14
dingbooptagree09:14
gsagiehi raofei, welcome! :)09:14
nick-maintroduce one db table for versioned object; another db table for distributed lock. all are implemented by SQL.09:14
nick-mayou can check the updated spec.09:14
gsagiedingboopt: would be great if you can review it as well and provide feedback09:14
*** amotoki has joined #openstack-meeting-409:14
dingbooptyes09:14
dingbooptwill do09:15
gsagienick-ma: ok sounds great, any help that you would like to have oanson help with?09:15
gsagieerr any task09:15
nick-mathe testing result is that I concurrently creates 10 subnets and it works.  But it may bring overhead on sql backend due to isolation level09:15
nick-maproblem09:15
*** markvoelker has quit IRC09:16
nick-maneutron by default sets isolation level to REPEATABLE READ. but it is not good for SQL lock statements. the mysql official suggests to use READ COMMITTED which is by default in postgresql. but neutron core team refused during some mailing list discussion. this problem is also in nova team.09:16
nick-mathere are no solution in the upstream because this is the common problem for almost all the projects.09:17
gampeli see wnats the process to change that is it in the code or configration09:17
dingbooptchanging the isolation level may cause problem to exsting neutron code09:18
nick-macode conversion. lots of db codes are assumed under REPEATABLE READ.09:18
*** zeih_ has quit IRC09:18
nick-mayes09:18
nick-madingbo is right.09:18
*** Shlomo_N has quit IRC09:18
gsagieyou mean the seperation of network and subnet?09:18
gsagieto two objects in dragonflow model09:18
*** ShlomoN has joined #openstack-meeting-409:18
gampelOK there some connectivity issues for gal09:19
nick-mano, currently i don't change the schema.09:19
dingboopttransaction isolation leve09:19
dingbooptl09:19
nick-mai think if the code is working for the current schema. it is also working for changes in the later stage.09:19
gampelnext stage is to to the compare and swap ? will then the DB setting effect the performance09:20
*** oanson has quit IRC09:20
*** saggi has quit IRC09:20
*** Shlomo_N has joined #openstack-meeting-409:20
gampelnick-ma: you mean the effect is when you lock the version table09:21
nick-macompare and swap is based on what Db backends we use. ETCD provide compare-swap for value. zookeeper provides compare-swap for internal version. if we need it, i can provide another spec on that.09:21
nick-mayes, lock statements are working, but not optimal.09:22
gampelI see, I think that the end goal is to do the compare and swap09:22
gampelbut i agree we need to do small steps and make sure we understand the problems09:22
nick-maanother test is also needed for Galera clustering to demonstrate the sql lock mechanism.09:22
*** gsagie has quit IRC09:22
*** gongysh has quit IRC09:23
gampelOk we will try to set it up here, you are using Galera clustering in your solution  ?09:23
nick-mai'll do it this week and try to finish the current work using sql lock to protect concurrent writes on DF DB.09:23
*** ShlomoN has quit IRC09:23
gampelthats great i will try to review your patch today09:24
nick-mano, i'll evaluate and test the code under Galera to see the effect.09:24
*** gsagie has joined #openstack-meeting-409:24
nick-mayou can review them tomorrow. i'll update it this evening.09:24
gsagieok sorry09:24
gampelOk will do09:24
gsagiewe have internet problems here :)09:24
gsagiegampel, nick-ma: problem solved?09:24

*** yuli_s2 has joined #openstack-meeting-409:25
gampelI think we coverd this topic with action items form me and nick-ma to test under Galera09:25
yuli_s2I am back09:25
gsagie#action nick-ma, gampel test DB consistency under Galera09:25
nick-mayes. if you have any problems or questions, please review my spec.09:26
gsagieokie great09:26
gampeland we need to understand better the effect of the DB setting EPEATABLE READ/ READ COMMITTED09:26
nick-mai'll make sure the spec and code are consistent.09:26
*** yuli_s has quit IRC09:26
gsagiegampel: anything on the publish-subscribe?09:26
gampelwe merged the API09:26
gsagietoo bad DuanKebo is not here, as we need to sync regarding redis :(09:27
gampelcurrently  all teh publishing is done via the neutron server09:27
gsagiewe will schedule meeting for tommorow to discuss it09:27
gampelhe told me he will join shortly09:27
gsagieokie great, oanson is adding monitoring thread09:27
*** oanson has joined #openstack-meeting-409:27
gsagieoanson: hi, just in time :)09:27
gampelyes we are adding a publisher service09:27
gsagiewould like to describe the monitoring threadas09:28
gsagiefor tables09:28
gsagie?09:28
oansonSure09:28
oansonThe plan is to add a separate service, i.e. separate process, for publishing info.09:28
gsagie#info pub-sub service https://review.openstack.org/#/c/281336/09:28
oansonOn this service, we plan to run a thread monitoring the distributed db for changes09:28
gsagie#info pub-sub api https://review.openstack.org/#/c/282879/09:29
oansonThis means that the monitor will only run once on a neutron server, and not once per CPU/core09:29
oansonA serivce is necessary in most cases, since binding the socket (for TCP/IP communications) can only be done from a single process09:29
gampelit is impotent  to note that q-svc is forked per core, so currently  we run it multiple time in the same machine09:30
*** pbourke has joined #openstack-meeting-409:30
oansonWe'll make the inter-process and network communications pluggable, so in case a published event doesn't need to go through the service (e.g. UDP), it can bypass it and go directly out the network09:30
oansonIn that case, the service will only be for DB table monitoring.09:30
gsagieokie, good work oanson, you believe it can be done this week? we do need to see how we help on the redis part as well, to have it act similar to this09:31
oansonDefinitely will be up for review this week09:31
gsagie#action oanson pub/sub service patch for review09:31
gsagieok great, thanks09:31
gampelwe currently think to call it publisher service , if there are any other suggestion it will be great09:31
gsagiedb-publisher-service09:31
gampelsound good to me09:32
gsagiepublisher service sounds good either way09:32
gsagiegampel: anything else open on this front? we do need to start test it09:32
oansondf-publisher-service, in case it ever publishes non-db related events09:32
gsagiemore often09:32
gampelyes i need to add the service discovery table for all the publishers09:32
gsagie#action gampel add service discovery DF table for publishers09:33
gampeland will address all the comments on teh spce please review09:33
gsagieyes, in general i think we want to have all/most of our configuration from the DB09:33
gsagieless use of configuration files09:33

gampelhe is in another meeting, let me check09:37
gsagiethe spec was merged, we talked and decided to not move the functionallity from the controller09:37
gsagiebut have seperate module just for the selective/proactive part, and then when everything is done maybe we can consider rafactoring09:37
gampelOK09:38
gsagiereason is there are many people working on the same code and we dont want to introduce major09:38
gsagiecode refactoring that are not needed, personally i dont think they are right09:38
*** iceyao_ has joined #openstack-meeting-409:38

gsagiewe will need to make sure this is all good and works with current L309:40
gsagieapplication as it changes cookie for flows09:40
gsagiei think we should set the L3 proactive app as default for now09:40
gsagieany thoughts?09:40
gampelwhats the namespace needed for the L3 how many bits09:41
gsagiethere is one more optimization that is needed in the L3 app and thats not using flows from every subnet to every subnet but just09:41
gampelthe cookie  is 64 bit, if we use 32 bit for the reliability is it enough ?09:41
gsagieclassifying the router id (giving it a register) and then having one flow per router interface09:42
gsagiegampel: for reliability even less is enough it basically only need to be 2-3 numbers09:42
raofeiyes, I think so, using router id instead of subnet09:42
gsagie2-3 options09:42
gampelyes we discuss this in the past how big effort  an effort you think it is09:42
gsagiegampel: not big at all we already have everything in place09:42
gsagiei will start working on it09:43
*** thorst has quit IRC09:43
gsagie#action gsagie enhance L3 apps to use one flow per router interface based on router id09:43
gsagiethen, i think we dont even need the cookie09:43
gsagiefor the L3 proactive app09:43
oansongsagie, you mean one flow from every subnet to every router? Or one flow from every subnet to each router, and then flows between routers?09:44
oansonto its* router, in the second question.09:44
gsagieoanson: regardless of proactive/reactive, i mean the flows at the first table, we will only need one flow per router interface09:44
gsagieright now we have from each router interface to all the other interfaces to check there is route09:45
gsagiefor proactive, we will have to detect the destination port in the next table09:45

gsagieas its going to be the default implementation09:46
DuanKeboEran has posted some comments about redis driver09:46
DuanKeboFeipeng will discuss them with Eran09:46

gsagie#action gsagie.gampel,DuanKebo,feipeng sync regarding redis db efforts and see we on schedule09:48
DuanKeboWe also need to modify the df plugin to support redis db09:48

gsagieyes it has some nice features regarding selective proactive09:50
gsagieit also filter things in the publisher which is good09:50
gsagieokie09:51
DuanKeboHi gal, we need the a "tanant_id" para in the north bound db interfaces.09:51
nick-maokie09:51
gampelwe need to test it in scale , zmq has a publisher XPUB but it does not scale when doing publisher side filtering09:51
gsagieDuanKebo: i am adding this part right now, what do you see is missing?09:51
gsagie#action test redis pub/sub with publisher side filtering09:52
gampelin ZMQ we currently use PUB which is client side (we need to test the trade off network/server load)09:52

gsagieDuanKebo: i add it to db_api, i think its already added and the selective proactive will also need to call the pub/sub "register_topic" with new tenant ids09:53
gsagieto register for pub/sub in addition to bringing the correct DB09:53
gsagieour Neutron plugin should already populate all objects with another parameter called "topic" which we pass to the DB_API09:53
gsagiethats the tenant id09:54

*** openstack changes topic to ": Announcements (Meeting topic: ironic_neutron)"16:02
SukhdevAnybody has any announcements?16:02
jrollwe made good progress on the first api patch during the midcycle last week \o/16:02
jrollunfortunately, we also agreed the second one needs some heavy rework :(16:03
Sukhdevjroll : can you elaborate, please16:03
devanandao/16:03
jrollso devananda probably is better with the words on this at this point16:04
sambettso/ Hi all16:04
jrollbut basically, the way the pluggability works and drivers are loaded, etc, needs to be refactored16:04
jrollwhich is the majority of the patch16:04
vsaienko\o16:04
jrollfor reference, this is https://review.openstack.org/13968716:04
devanandaas it stands, that patch is adding a per-node setting (exposed in the API) to change what network provider that node uses16:04
jrollI was meant to work on this friday, but due to travel terribleness, did not get to it. I can hack on it tomorrow.16:05
devanandathat is basically how we plan to handle driver composition16:05
*** sridhar_ram has quit IRC16:05
devanandahowever, the patch doesn't have a well-defined internal API, eg. to support out of tree network provider implementations16:05
devanandaso we agreed to refactor it so that it does16:05
devanandaand create a NetworkProviderInterface API (internally) -- much like we have a DeployInterface and BootInterface, etc16:06
devanandajroll: that about sum it up?16:06
jrolldevananda: yes, I think so16:06
vsaienkodevananda: who is going to handle refactoring?16:07
Sukhdevdevananda, jroll: thanks for clarification16:07
*** belmoreira has joined #openstack-meeting-416:07
jrollvsaienko: I plan to get to it tomorrow16:07
jrollunless deva really wants to tackle it16:07
jrollprobably start today but likely not finish16:08
Sukhdevjroll : just for clarification, with this refactoring, will there be still need to specify network_provider in the config file?16:10
*** armax has joined #openstack-meeting-416:10
jrollSukhdev: that was a default, if not specified on the node... I would think we would require it to be set on the node itself16:10
sambettsI think we'd still need a default to fall back too if the nodes network interface is None?16:11
SukhdevGot it16:12
jrollsambetts: if we're treating it as a driver, it should be a required field IMO16:12
jrolljust like node.driver is required, probably need to do it in validate16:13
* jroll needs to check if driver comp spec covers this16:13
sambettsyup, that sounds good16:13
* sambetts was wondering if we had an optional config parameter that set the network interface on a newly enrolled node to the default 16:14
jrollwe do in the current patch, I'm not so sure if it's a good idea now though16:14
jrolldevananda: ^ opinions?16:14
devanandajroll: I need to review the driver comp spec as well16:15
Sukhdevsambetts: the default in the config will apply to all nodes including newly enrolled nodes as well, no?16:16
devanandahonestly, I do not want to hold up the networking work for that spec, so if we don't get the internal API right, we can iterate -- but we have to get the REST API right16:16
*** hdaniel has quit IRC16:16
devanandajroll: I'll dive into the driver comp stuff today16:16
jrolldevananda: sorry, my question was about your opinion on whether to require setting node.network_provider or allow a default specified in config16:17
devanandaoh16:17
devanandasorry16:17
sambettsI think that node.network_provider should be a required field, but there should be an option to set the default one when you enroll the node16:17
sambettsjust an idea16:18
devanandasambetts: that will be a cumbersome and breaking REST API change16:18
jroll?16:18
devanandasambetts: everyone enrolling nodes would have to pas a new option16:18
jrollhow does that break the REST API, this doesn't exist in the API yet16:18
jrolloh. ohhh.16:18
sambettsmy idea prevents them from having to pass an option everytime16:18
sambettse.g. if network_provider not passed, set the one from the config file16:19
jrollto be clear, even without the default, I'm not proposing an error on POST /nodes without network_provider set, but rather failing node-validate if not set16:20
devanandajroll: that is better16:20
jrollstill kind of a workflow break though16:20
devanandajroll: not if the default is the no-op (flat) network provider16:20
jrollI don't mind a default in config, or even hard coding flat default16:21
jrollyep16:21
devanandasince that's the default today (because there isn't an alternative)16:21
jrollnod16:21
jrollyeah, I can get behind that16:21
* sambetts nods16:22
jrollcool16:22
jrolllet's plan on that then and move on?16:22
devananda+1 for now16:22
Sukhdevthis makes sense to me16:22
devanandaI'm going to review dtantsur's spec in the meantime16:23
SukhdevIn a way this is the current patch's behavior -16:23

jrollsambetts: what pieces do you think would need to be overrideable there? or rather what would you like to see?16:32

*** jmckind has joined #openstack-meeting-416:32
*** DuaneDeC7 has quit IRC16:34
*** iyamahat has joined #openstack-meeting-416:34
sambettsjroll: for our oob network driver we have to unconfigure the networking with the machine still turned on for the programming on the BMC to work, right now this shuts it down before that call happens, so I'd love to override that but can't because its a separate function outside the iscsi class, so I have to override the whole passthru function below that16:35
jrolloh, yikes16:35
jrollso, that isn't ideal, but it is also fixable later16:36
jrollor we could quickly move it into the driver class so it's overrideable16:36
devanandafix seems straight forward: make those module-level methods into class methods16:36
devanandaright16:36
jrollyeah, seems sane, not much to discuss here :)16:37
jrollsambetts: leave a comment on the patch and it should get done16:37
sambetts:) cool, will do16:37
SukhdevAnything else?16:38
sambettssomething else I noticed is that depending on the ramdisk your using prepare instance happens either before or after local boot is configured, not sure if that will be affected by the networking work16:38

sambettsSukhdev: I'm working on some custom out of tree network providers so I'm probably hitting weird things that come from that16:48
*** fnaval has joined #openstack-meeting-416:49
Sukhdev:-)16:49
devanandasambetts: you're still going through neutron, but just changing the order of calls, making some extra hardware calls, etc -- right?16:49

Sukhdevsambetts : changing the order of calls to neutron - or making extra calls - I hope it the latter....16:51

SukhdevLets continue to discuss sambetts issue, but, also open up for Open Discussion as well - since only few min left16:53
sambettsmaking extra calls, a good example of the sort of thing we ran into is this: because we have to have the node on to configure the networking/bmc, the agent deploy driver complains that it can't soft power off the node because it can't access it16:53
sambettsonce we configure the tenant networks16:53
sambettsand go to reboot it16:53
sambettstbh most of these issues are down to our crazy stuff rather than the existing code16:54
sambettsanyway, RE our conversation 2 weeks ago, I've now posted this16:55
sambettshttps://review.openstack.org/#/c/277853/16:55
sambettsand we had a good discussion about it during the Ironic mid-cycle16:55

sambettsSukhdev: the midcycle one?16:56
Sukhdevsambetts : yes - that is where I track all these patches - makes it lot easier -16:56

Sukhdevsambetts : this is good stuff - thanks16:57
Sukhdevsambetts : I will review it - but, is it in line with the nova/neutron work?16:58
Sukhdevi.e. main port as access port and sub-ports as tagged ports?16:59
Sukhdevthis will be very useful for service BMs16:59
