slaweqralonsoh: lajoskatona: hi07:51
slaweqI just reopened https://bugs.launchpad.net/neutron/+bug/194420107:51
lajoskatonaslaweq: Hi07:51
ralonsohlet me check07:51
slaweqit seems it still happens even with os-ken 2.2.007:51
slaweq:/07:51
lajoskatonaso the ryu cherry-picks are not enough....07:52
slaweqlajoskatona: at least not those 2 which we were thinking that will help07:54
slaweqmaybe something else is also needed07:54
slaweqwe merged many of them recently and we didn't made new version of os-ken yet07:54
bcafarelslaweq: was it seen with periodic neutron-ovs-tempest-with-os-ken-master job? if yes we could add it to experimental to check with these recent patches08:11
bcafarel(unless we can trigger periodic from gerrit, but I don't think we can)08:11
slaweqbcafarel: I didn't check periodic jobs today08:11
lajoskatonabcafarel: I haven't seen in periodic jobs08:12
lajoskatonaat least in latest runs08:13
bcafarelhmm it looks green overall indeed08:13
eugenmayerwhen deploying neutron, it is for the l3 agent and the LB. Are those responsible to span networks across compute nodes and LB is for exposing internal services to floating IPs?08:15
slaweqbcafarel: I saw it maybe twice during this week in the check queue08:16
slaweqso it's not as often and it's likely that we will not hit it in the periodic job often08:16
slaweqeugenmayer: I'm not sure if I understand Your question08:17
slaweqgenerally L3 agent is responsible for configuration of the neutron routers for tenants08:17
slaweqand LB agent is providing L2 connectivity for ports (vms but also router ports)08:18
slaweqfloating IPs are configured inside routers by L3 agent08:18
eugenmayeri'am new to openstack, so i could imagine my questions are just not precise enough / use the wrong terms. Please bear with me on that, i try to adopt08:19
eugenmayerCurrently i try to understand adopt how the distributed features for storage (cinder) and networking are integrated and where / how those service run.08:20
eugenmayerIn terms of networks, i have 2 questions in common, the one asked before was about something like 'considering that i need to expose floating IPs and have LANs for my VMs', i do not understand why i get asked 'where to deploy neutron to' - for my idea (naive) it must be on each compute node08:21
slaweqeugenmayer: for neutron You can start with https://docs.openstack.org/neutron/latest/admin/intro-os-networking.html08:22
eugenmayersure, will read that and ask if anything is unclear - maybe / hopefully more specific then!08:22
slaweqneutron l2 agent (ovs or lb) needs to be on each compute and networker node08:22
slaweqdhcp and l3 agent can be only on networker nodes 08:23
slaweqif You want to use dvr with ovs agent, You will need to have l3 agents on all computes as well08:23
eugenmayerdvr / ovs are yet not known to me08:23
eugenmayermaybe part of the docs08:24
slaweqif You want to plug Your vms directly into the provider network (like vlan) You may have only neutron-ovs-agent (or lb-agent) on compute and networker nodes and dhcp-agent on networker nodes08:24
slaweqyou need to read about it in docs08:24
slaweqthere are also some good talks available on yt for example08:24
eugenmayerthat is an open question for me. I have the following situation - each controller and all nodes have a common network (an vswitch i get from my dc, spanning across all barebones). I have 2 of those vswitches plannes: one for cluster/management and one for the VM's lan, so vlan 4000 and 400108:25
eugenmayerfor proxmox, i just did the following: added the interface for 4000/4001, added a bridge to that interfaces and the i could spawn vms on that bridge, being part of that network - that is something i will need to do with OpenStack too08:26
eugenmayer(beside that, i will have an addition vlan 4003 which offers all the floating ips). That all said, my barebone has 1 nic, multi vlans08:27
eugenmayerbut i guess, i read those docs first and ask questions later (to hopefully not waste any of your time)08:30
ralonsohslaweq, lajoskatona I think the problem is in the OF controller09:05
ralonsohhttps://paste.opendev.org/show/810068/09:05
ralonsohwhen the of controller is restarting (because we have changed the configuration)09:05
ralonsohwe can receive a "unknown dpid" message, and the controller will throw a InvalidDatapath exception09:06
lajoskatonaralonsoh: it looks like there's already a msg with some xid09:06
ralonsohthat's ok because we handle it properlu09:06
ralonsohyes09:06
ralonsohthat's the second case09:06
ralonsohthe of controller does not return anything09:06
ralonsohand we timeout09:06
ralonsohso, IMO, we should have a timeout context, smaller than the OF controller timeout09:06
ralonsohholding the send message stuff09:07
ralonsohif the message is not received, we can retry again09:07
slaweqof controller timeout is configured somewhere in neutron?09:07
ralonsohyes09:07
ralonsohone sec...09:07
slaweqand it's probably 300 seconds or more, right?09:07
ralonsohyes09:08
ralonsoh500 secs09:08
ralonsoh300 secs09:08
slaweqok09:08
slaweqso we should have this context timeout smaller, like e.g. 60 seconds maybe, right?09:08
ralonsohso let me propose a patch, that will describe better what I'm saying09:08
slaweqralonsoh++09:08

blmtmorning all10:11
blmtI have an OVN issue that's driving me insane: random packet loss on floating IP (using OVN DVR)10:12
blmtthat started either out of the blue or as a consequence of a network disruption (not sure things are linked)10:14
blmtanyone has any hint on how to do some OVN specific debug ?10:15

eugenmayerblmt, are your barebones hosted on hetzner?10:48
blmthi eugenmayer, no we have everything in house.10:48
eugenmayerok, because i had a weired, similar issue on their when using snat outbound rules on the additional (floating) ips10:50
eugenmayerwhich was heavily impacting traffic/network responses10:51
blmtsnat outbound rules from openstack?10:55
ralonsohslaweq, lajoskatona https://github.com/faucetsdn/ryu/issues/15910:55
ralonsohI think the problem is in the os-ken library10:55
ralonsohI've opened a issue in ryu, just to ask for expert advise on this10:56
slaweqralonsoh: thx, let's see what ryu devs will say about it :)10:57
