dimssdake_: ping13:37
sdake_shoot dims13:38
dimssdake_: got the magnum process to come up at least - https://review.openstack.org/#/c/168194/ - need your help with the devstack settings - https://review.openstack.org/#/c/168194/18/devstack/settings,cm13:39
sdake_dims I am not sure how ot set up devstack to run in the gate - best to ask on #infra13:44
sdake_It may involve adding br100 to the flat_interface tho13:44
dimssdake_: slightly more targetted question then :) assuming we can live with defaults for FLOATING_RANGE, PUBLIC_NETWORK_GATEWAY, FIXED_RANGE, PUBLIC_INTERFACE...do we really need  Q_USE_SECGROUP, ENABLE_TENANT_VLANS, TENANT_VLAN_RANGE for magnum to work?13:47
sdake_I idea13:48
sdake_no Idea13:48
sdake_dude, I spent 200 hours of my life getting neutron to work13:48
sdake_I finally figured it out13:48
sdake_and understand a bit about neutron13:48
dimsack. just feels like it got thrown in because someone had it in their settings13:48
sdake_but those  flags, I dont understadn13:48
dimsthat's why i asked :)13:48
sdake_I didn't have those in my settings...13:48
dimssdake_: can you paste me your settings, just in case :)13:49

sdakehongbin thanks for looking into it15:18
sdakehopefully during liberty I'll have more time to contribute to magnum15:18
sdakecode wise15:18
hongbinthat's fine15:19
hongbinOne thing I need clarification15:19
sdakethanks for taking over that blueprint15:19
sdakeshoot15:19
hongbinWhat is the split brain scenarios you mentioned15:19
sdakeif the network partitions while a lock is held IIRC it looked like the stack would lock up forever15:20
sdakemaybe thats fixed in the current implementation15:20
sdakeI think therve did the work - check commit logs and contact him directly on #heat15:20
sdakeor maybe it was someone else, I don't recall15:20
sdakeideally the network shouldn't partition15:21
hongbink15:21
sdakebecause it should be running in replication mode (bonding)15:21
sdakeevery flat and public network shoudl have two nics running in bond15:21
hongbinwhat do you mean exactly for "network partition"15:21
sdake(4 nics)15:21
sdakea network partition is for example when you have 3 racks with TORs, and the middle TOR goes to lunch15:21
sdakethis partitions the middle rack into a unique cluster15:22
sdakeif it still has access to the db bad things could happen15:22
hongbinI see15:22
sdakeideally the management network (public_network) shouldn't have that happen15:22
sdakeI think the management network is the public network, but ideally it should be a separate vlan15:23
sdakebut I have zero operator experience, so I'm the wrong guy to ask15:23
sdakeit looked more like a theoretical problem rather then one I could produce15:23
sdakethe code has logic to unlock a locked stack15:23
sdakeif the lock goes out to lunch15:23
sdakebut it relies on telling the engine that launched the stack to release it15:24
sdakeie: you are no longer respponsible for this stack, I am15:24
sdakethat is how it worked 1+ years ago15:24
sdakethe approach is viable though15:24
sdakeI'd go with it15:24
hongbinDigesting that15:24
sdakeit tells the engine via amqp15:25
sdakeso if amqp partitions, it can't tell teh stack15:25
sdakeresulting in a locked stack forever15:25
sdakethey may have a dded logic to just take it over assuming the engine is dead15:25
hongbinI see15:26

*** sdake_ has joined #openstack-containers15:26
*** kebray has joined #openstack-containers15:29
hongbinsdake: Thanks for the information. I guess I will start by locking the bay first (by copying the locking logic from Heat). Then, we can revisit the hashing again.15:29

*** suro-patz has quit IRC15:37
hongbinsdake: or do you think we should investigate more about the direction before getting started?15:38
sdake_that is what heat does15:40
sdake_pings15:40
sdake_i think we need no more investigation15:41
sdake_we are running short on time15:41
sdake_we can always adapt later if the field finds problems using it15:41
hongbink. get that15:41
sdake_so far the field uses heat in horizontal scale mode and it doesn't get much complaint15:41
hongbinget that. thx.15:42
*** dboik_ has quit IRC15:42
sdake_if it got complaints  I'd think about a different approach15:42
sdake_the reason I always wanted consistent hasing in heat is the heat engine *DOES* maintain state15:43
sdake_so it would have made more sense for that project15:43
*** dboik has joined #openstack-containers15:43
sdake_for example killing a heat engine mid stack deployment results in a busted stack15:43
sdake_it has to be deleted and recreated15:43
sdake_the heat community is working on fixing that15:43
hongbinI see15:47
