openstackLaunchpad bug 1788865 in neutron "neutron-openvswitch-agent interface monitor does not work if ovsdb-client generates warnings (ovs 2.10)" [Undecided,New]13:53
slaweqbcafarel: looking13:53
bcafarelotherwiseguy: ^ some reading for you too, especially if you have opinion on moving ovsdbmonitor to native interface13:53
slaweqbcafarel: for me it's clear13:54
slaweqbut I know already background of this issue :)13:54
slaweqbasically IMO it's fine, ovsdb monitor shouldn't be killed always if any warning will be send to stderr13:55
bcafarelack I will take a look into that13:57
bcafareland hopefully that is another item we can switch to native later on13:57

cgoncalvesdalvarez, re: https://review.openstack.org/#/c/596295/14:14
dalvarezcgoncalves: ack! i plan to complete my patch btw14:15
dalvareznext week...14:15
cgoncalvesI'm running into same issue and have a patch open that is not being verified even when cinder and swift are disabled14:15
dalvarezoh damn14:15
dalvarezcgoncalves: it's driving me crazy the cinder thingy14:15
cgoncalvesI was told that a RDO promotion is required14:15
dalvarezoooooook14:15
cgoncalvessooooooooooo... wait impatiently :P14:15
dalvarezhow come? can't we just depends on something? i thought containers were recreated14:16
slaweqhaleyb: hi, can You quickly take a look at https://review.openstack.org/#/c/594326/ if You will have few minutes?14:16
cgoncalvesdalvarez, I thought so too. depends-on doesn't work. either wait for next promotion or flip update_containers to True (didn't test, was suggested doing it as workaround)14:16
dalvarezsigh14:16
dalvarezahh i thought update_Containers was set to True by default14:17
dalvarezcgoncalves: where can i switch that?14:17
cgoncalvesdalvarez, not exactly sure. I see it being set in tripleo-quickstart-extras and in tripleo-ci14:18
haleybslaweq: ack, i was actually just starting to review last night and got interrupted.  just had some nits on usage message i think14:26

abaindurhad another dnsmasq related issue19:21
abaindurhttps://bugs.launchpad.net/neutron/+bug/176448119:21
openstackLaunchpad bug 1764481 in neutron "Sometimes dhcp_releasepackets don't reach dnsmasq" [Medium,Fix released] - Assigned to Brian Haley (brian-haley)19:21
abaindurWe have the fix for that, where it retries 3x, but still hit it... see my last 2 comments19:21
* mlavalle looking19:21
abaindurNoticed that even when we manually enter the dhcp_release command, say even 20+ times, we see the DHCP Release packets in tcpdump on qdhcp's tap interface... but still dnsmasq does not register the lease, and we see no DHCPRELEASE logs in syslog19:22
abaindurThis happens randomly for some networks only... others are fine. There's something more fundamentally broken here with dnsmasq than simply losing a UDP packet or two19:23
*** aicilamd has quit IRC19:23
abaindurI realize technically this isn't a neutron bug, as neutron is doing its job and dhcp_release is sending the Release pkts...19:23
*** aicilamd has joined #openstack-neutron19:24
mlavallehaleyb: ^^^^^\19:24
abaindurBTW we hit this on both Centos 7.2 and Ubuntu14, and dnsmasq 2.66 and 2.7x19:25
mlavalleabaindur: I'll look at it slowly later today. probably we need to engage the dnsmasq guys19:25
abaindurits strange that this issue only started cropping up very recently, in past month or two... havent seen it in past 3 years19:25
