toskyok, so quick update for logs (and posterity)14:06
tellesnobregayes14:06
toskyI'm still working (with a WIP review) on S3 support in scenario testing14:06
toskyon the way, thanks also to new inputs, we have some fixes for image building on ubuntu and in general14:07
toskyno bashism in image building, and curl to solve some issues with wget when downloading from tarballs.openstack.org14:08
toskyboth changes, when approved, should be backported at least back to queens14:08
toskythat's putting the other work (python3, sahara-dashboard integration test) a bit on the back seat, but that's what it is14:09
tellesnobregaRight now I finished the split plugins work phase 2, that is, the plugins are split into its own repo and unit tests are passing for all 6 six plugins14:09
tellesnobreganext steps are pushing those patches upstream (so we can get some eyes on it) and start scenario testing them14:10
tellesnobregaboth with scenario tests from sahara and manual testing as well14:10
toskyyeah, some manual test will be needed for sure before doing the split14:11
toskyI'm probably going to write down few guidelines about the packaging and ask for feedback first on #rdo and then copying the other maintainers14:12
toskywe will need to fix the devstack plugin to install the existing plugins too14:13
tellesnobregayes14:13
toskythat should make it transparent from the point of view of zuul jobs, I hope14:13
tellesnobregaprobably, we can check with infra later14:13
tellesnobregathat is it from me14:14
tellesnobregaon updates14:14
tellesnobregaanything else from you tosky?14:14
toskyno, nothing else14:15
tellesnobregalets move on14:15
toskybasically after the split is done we will have to hurry up with API v2 and Python314:15
toskyand that will be our Stein :)14:15
tellesnobregado you have specific topics that I can use as title? or can we go into open discussion?14:15
toskyno specific topics14:16

*** openstack changes topic to "Open Dicussions (Meeting topic: sahara)"14:16

tosky(and everyone else who want to re-read it)14:17
*** hongbin has joined #openstack-meeting-314:17
tellesnobregatosky, sure14:17
tellesnobregaI will review it today14:18
tellesnobregaas soon as I'm out of meetings14:18
tellesnobregawe should've merged that before I split the plugins14:19
tellesnobregabut well14:19
tellesnobregawe can always rebase14:19
toskyyep, that's why I suggested you at some point to script the process :)14:19
toskyalso the patches which use curl and remove bashism touch the plugins code14:20

mlavalleand came up with a plan on how to fix it15:09
mlavalleI was expecting an update from Swami, but since he is not attebding the meeting, let's wait for an update in the bug15:09

mlavalleThe only change since then is that the test was marked as unstable15:11
mlavalleNext one is https://bugs.launchpad.net/neutron/+bug/179198915:12
openstackLaunchpad bug 1791989 in neutron "grenade-dvr-multinode job fails" [High,Confirmed] - Assigned to Slawek Kaplonski (slaweq)15:12
slaweqso I'm still working on it15:12
mlavalleany updates slaweq?15:12
slaweqI recently sent DNM patch which adds more logs to this grenade job15:12
haleybi sent this patch yesterday as well, https://review.openstack.org/#/c/607685/15:13
mlavalleis that the one we were re-checking a couple of days ago?15:13
slaweqbasically it looks like this instance starts pinging after about 4 minutes15:13
slaweqmlavalle: yes15:13
*** e0ne has joined #openstack-meeting-315:13
haleybit will make the rfp/fpr ARP entries permanent instead of dyanmic15:13
slaweqhaleyb: and on Your patch there was still same issue15:13
haleyb:15:13
haleyb:(15:14
slaweqbut I was today checking logs from Your patch and I found that there is still one STALE entry:15:14
slaweq169.254.125.69 dev rfp-a79c5312-8 lladdr aa:28:12:72:ae:2c STALE15:14
slaweqit's in qrouter-XXX namespace on host where instance is15:14
slaweqand when ping works, thos becomes REACHABLE15:14
haleybi'll have to see where that's getting set.  so is the gateway IP still STALE as well?15:15
slaweqhaleyb: I didn't have time to check why this entry is not added as PERMANENT15:15
slaweqhaleyb: no, this is the only STALE entry now15:15
slaweqnothing else like that15:15
slaweqahh, no15:16

slaweqthere is also:15:16

slaweqin fip-88d3d067-d1cb-4298-8c46-dfb3cac06d8915:16

haleybwe can at least try and track down the rfp/fpr ones, not sure about the fg- one15:18
slaweqif someone else wants to check, here is log from grenade job: http://logs.openstack.org/85/607685/2/check/neutron-grenade-dvr-multinode/48b00e1/logs/grenade.sh.txt.gz15:19
slaweqit has added some additional info like iptables-save, openflow rules, ip a, ip n, ip r from each namespace on each host and things like that15:20
*** negronjl has quit IRC15:20
slaweqthose logs are added after failed attempt of pinging FIP15:20
slaweqand then pinging is retried until it will be fine15:20
slaweqthen logs are collected once again15:21
slaweqand we were comparing log from moment "before ping starts working" and "after ping works"15:21
slaweqand only differences we saw with haleyb was those STALE entries in qrouter- and fip- namespaces15:21
slaweqmaybe someone will have any idea why it is like that15:22
mlavallein qr-xxx and fip-xxxx?15:22

mlavalleI've been working on this one15:26
*** moguimar has quit IRC15:26
mlavalleI was hoping to reproduce / debug it in a DVR-HA environment15:26
mlavallewhereas all the entries in the bug seem to refer to pure HA15:27
mlavalleI have a question for haleyb:15:27
haleybsure15:28
mlavalleI was looking at https://review.openstack.org/#/c/44251815:28
mlavallewhich is refered to in the bug15:28
mlavallewill the set up in that patch in the qr-xxx name space for ipv6 forwarding happen in the fip-xxx namespace if my router is dvr-ha?15:29
haleybmlavalle: i don't think so15:31
mlavalleok, so in my testing / debugging I need to get the fip namespace out of the way15:31
haleybipv6 n/s should be in qrouter, i can look at the bug too15:31
mlavalleif you have time, that would be welcome15:32
mlavalleI can also try testing / debugging with a pure HA router15:32
mlavallelike the one in the bug15:32
mlavalleThis seems to be the piece of code in question: https://github.com/openstack/neutron/blob/master/neutron/agent/l3/router_info.py#L68715:33

mlavalledavidsha: you are up15:37
davidshaHey, we're working on the refactor of the agent code and we came across abit of a problem for us. We're trying to move the driver, namespace manager and a few other objects into the router info class15:38
davidshathanks!15:38
davidshaProblem is the routerinfo class if inherited by NameSpace object and it causes a circular import15:38
davidshaWe're just trying to figure out what the best way to go about circuventing this is.15:39
mlavallewell, my first reaction is let's keep the separate. Isn't a router a specialization of namespace?15:40
mlavalleand the fact that you are hitting the circularity a sumptom that maybe the approach is not right?15:41
davidshaYes, but we wanted to move the NameSpaceManager into RouterInfo as a static variable within the class15:41
mlavallesymptom^^^15:41
davidshaNameSpaceManager imports NameSpace class to store in a dict15:41
mlavallehas any of that re-factoring been pushed to gerrit?15:42
davidshaMaybe this discussion might be better on the patch when it's pushed15:42
mlavalleyeah, hence my question ^^^^15:42
mlavalleI think so15:42
davidshaAn early version was but this is a bit durther along that the previous patch15:43
