* haleyb will wait knew some would be late15:02
Swamihi15:03
haleybhi Swami15:03
haleybi guess we can start then15:03
haleyb#topic Announcements15:03
*** openstack changes topic to "Announcements (Meeting topic: neutron_l3)"15:03
SwamiI think the turnout might be low, because of the holiday week.15:04
haleybThere will be no meeting next week as I'm assuming everyone in US will be on break15:04
Swamihaleyb: makes sense.15:04
Swamihaleyb: we discussed about the 6a.m timeslot a while back, what is that for. Is it for the L3 meeting or is it for the other meeting.15:05
haleybOnly other announcement is Stein-2 is January 7th, so we're in the last couple of weeks to merge code15:06
haleybSwami: miguel wanted to see about making this meeting one hour earlier, which would be 6am your time15:06
haleybhe has a conflict at this time15:06
Swamihaleyb: Ok. That's what I thought.15:07
Swamihaleyb: Do you have any big plans for the break.15:07
haleybSwami: nothing big, skiing if the weather cooperates, how about you?15:08
Swamihaleyb: I have taken off next week, but need to check with my kids where they wanted to go.15:08
haleybDisney Land Dad! :)15:10
Swamihaleyb: True, going to Southern California would be a nice choice based on the weather conditions.15:11
haleybalright, let's continue...15:12
haleyb#topic Bugs15:12
*** openstack changes topic to "Bugs (Meeting topic: neutron_l3)"15:12
SwamiThere is a new bug that was filed this week for DVR. #link https://bugs.launchpad.net/neutron/+bug/180715315:13
openstackLaunchpad bug 1807153 in neutron "Race condition in metering agent when creating iptable managers for router namespaces" [Undecided,New]15:13
* haleyb was supposed to triage that one15:13
SwamiThere is a patch under review for this bug. #link https://review.openstack.org/#/c/621165/15:14
SwamiI have not yet triaged this, but will take a look at it. It seems this happens when the namespace is not ready for the router and when the metering rules are getting added.15:15
haleybi think it can happen based on other bugs we've fixed in the metering agent15:15
Swamihaleyb: agreed.15:15
haleybi've update it15:16

SwamiThe next one in the list is #link https://bugs.launchpad.net/neutron/+bug/179499115:16
openstackLaunchpad bug 1794991 in neutron "Inconsistent flows with DVR l2pop VxLAN on br-tun" [Undecided,New]15:16
Swamihaleyb: I think we got some more information about the bug.15:17
SwamiThis one as such could not be reproduced and i am not sure if only load on the compute will cause this or constant restart of the openvswitch agent would cause this. The table 22 seems to be the odd one right now.15:17
SwamiLet me focus on that table to see why the l2pop rules are getting messed up.15:18
haleybok, thanks15:18
* slaweq is back, sorry for being late15:18

openstackLaunchpad bug 1774459 in neutron "Update permanent ARP entries for allowed_address_pair IPs in DVR Routers" [High,Confirmed] - Assigned to Swaminathan Vasudevan (swaminathan-vasudevan)15:19
Swamihaleyb: slaweq: I need someone to take a look at this patch. Since it is getting more complex, we don't want to mess up the flow rules. haleyb I did read the comments from last week that you are in the process of reviewing this patch.15:20
Swami#link https://review.openstack.org/#/c/601336/15:20
haleybSwami: yes, have not finished yet15:21
Swamihaleyb: I have been addressing some refactor comments from Ryan so far.15:21
SwamiBut really we need L2 experts to take a look at it.15:22
slaweqSwami: I'm not an expert but I will take a look15:22
SwamiThe concern i have is on the exposing the DVR MAC on the local switching table in br-int.15:22
Swamislaweq: Thanks, I would appreciate.15:23
Swamihaleyb: I think that's all I had for the DVR bugs. Back to you15:24
SwamiI may have to drop in another 5 mins.15:24
SwamiHappy Holidays to all.15:24

*** davidsha has joined #openstack-meeting-315:34
haleybi have not looked at review yet15:35
liuyulongYes, I'm still working on this.15:35
slaweqthere is WIP patch for this one but it looks that this test is still failing on it :/15:35
liuyulongAll the failed LOG has `qg-port` not present in bridge br-int info.15:36
*** evrardjp has quit IRC15:37
liuyulongBut I'm not quite sure if this is the root cause.15:37
haleybliuyulong: the l3-agent log has that or ovs agent?15:38
liuyulongovs-agent15:38
liuyulongThe LOG is basiclly near the ping loss time.15:39
slaweqliuyulong: that is interesting15:40
liuyulongI cannot reproduce the issue in my devstack env. Create a router, set gateway, ping gateway IP, kill -9 l3 agent. Everything works fine then.15:40
haleybi didn't see that in the latest logs, maybe i'm missing it15:41
*** evrardjp has joined #openstack-meeting-315:41
slaweqliuyulong: does it happen on "host" which should be master or backup?15:42
slaweqor both?15:42
liuyulongmaster for now, since the gateway IP set there. Or maybe I should kill the backup l3-agent and see again.15:44

*** moguimar has quit IRC15:46
haleybah, i was looking for the wrong string, it's in the latest log too15:46
*** moguimar has joined #openstack-meeting-315:46
slaweqI'm not sure if that is real issue - we are using same ovs for all tests/agents so maybe it's just side effect of adding port to some other bridge15:47
liuyulongThis is really a tough one, but IMO the l3 agent may remove the qg-device unexpectedly15:50
slaweqliuyulong: if it is like You are saying, then it's real issue, not only tests issue :/15:50
liuyulongL3 agent may get a router info without gateway info due to the re-consuming notification.15:51
liuyulongBut seems not so much right, because l3 agent will try to retrieve router info from neutron-server everytime.15:52
liuyulongIf you guys have any information please directly add it to the gerrit. : )15:54
haleybyes, i thought we just changed that code for the 2 dvr routers case, i'll try to look at the review again15:54
slaweqhaleyb: yep, but IIRC it was failing before this big patch too15:55
