He goes as far as removing the rollback mechanism 15:12:46 any other comments? 15:13:50 ok, next up is https://bugs.launchpad.net/neutron/+bug/1627480 15:13:50 Launchpad bug 1627480 in neutron "create_port can succeed without returning fixed_ips on all requested subnets" [High,Confirmed] - Assigned to James Anziano (janzian) 15:14:17 I've been looking through a few different occurrences of this bug on Kibana 15:14:55 For the most part, the window appears to be around 0.6 seconds from port creation to deletion to bug 15:15:44 from what I saw during our meeting, it's related also the DHCP port creation or update, right? 15:15:49 janzian: ^^^^ 15:16:07 I believe so, yes 15:16:24 I'm still trying to figure out an optimal solution. The obvious answer is locking the relevant parts of the database during the process, but I feel like that's much too big a performance hit 15:16:46 mhhh, before going there///// 15:17:51 have you seen this failure being concurrent with an operation on the port's subnet, specifically deletion? 15:18:45 Yes. Here's one of the examples I've been looking at: http://paste.openstack.org/show/602933/ 15:19:46 The subnet is deleted very soon after the DHCP port was requested to be created, causing the bug 15:20:21 ok, so it is very similar to what I am seeing with the Flusherror bug 15:20:44 let's look at this together 15:21:29 Sounds good to me 15:21:37 any other comments? 15:22:58 ok, moving on 15:23:05 https://bugs.launchpad.net/neutron/+bug/1509004 15:23:05 Launchpad bug 1509004 in neutron ""test_dualnet_dhcp6_stateless_from_os" failures seen in the gate" [High,Confirmed] 15:23:29 It seems this one is related to failures in the DVR job now 15:23:53 which seems to have a failure reate of ~25% 15:24:19 * haleyb didn't know of any DVR issues 15:24:41 maybe I misunderstood from the CI meeting 15:24:48 I will go back to the logs 15:25:14 i've also been offline a few days :) 15:27:27 haleyb: take a look here: http://eavesdrop.openstack.org/meetings/neutron_ci/2017/neutron_ci.2017-03-14-16.00.log.html#l-38 15:28:16 Let's follow up after the meeting 15:28:33 sure 15:29:10 any other bugs from the team? 15:29:49 ok, moving on 15:30:04 #topic Prefix Delegation 15:30:40 A copuple of days ago we merged https://review.openstack.org/#/c/413137/ 15:30:45 couple^^^ 15:31:15 which I belive was the last PD related patchset up for review 15:31:52 any other comments? 15:32:38 ok, moving on 15:32:41 yes, that was the last one 15:32:46 sorry, distracted 15:33:00 thanks 15:33:13 #topic Routed Networks 15:33:46 I had a brief irc chat with kevinbenton regarding the floating ip RFE last Friday 15:34:09 He mentioned the drivers couldn't review the RFE last week 15:34:21 But that they will give it a try this week 15:34:38 I thought john-davidge might be interested on this :-) 15:34:52 mlavalle: That's good news, thanks :) 15:35:08 any other comments? 15:36:11 #topic Open Agenda 15:36:27 Any other topics that should be discussed here today? 15:37:17 * john-davidge will be on PTO next week 15:37:31 john-davidge: enjoy! 15:37:47 mlavalle: Thank you :) Much needed ski holiday 15:38:04 ok, guys, thanks for attending 15:38:13 have a nice rest of your days :-) 15:38:18 #endmeeting
