15:04:25 * carl_baldwin wanders in...
15:04:29 <haleyb> Mitaka-2 is quickly approaching - Jan 16th or so
15:05:11 <Swami> I think the attendance is going to be pretty thin today and let us get started.
15:05:21 <haleyb> Swami: do you want to talk about migration or bugs first?
15:05:43 <Swami> haleyb: there are only two new bugs this week, so let us get started with the Live migration first.
15:05:54 <haleyb> #topic Live Migration Discussion
15:06:23 <Swami> haleyb: carl_baldwin: we started a discussion about the live migration couple of weeks back before the break.
15:07:05 <Swami> oleg and myself was trying to capture all the information in the launchpad bug #link https://bugs.launchpad.net/neutron/+bug/1456073
15:07:06 <openstack> Launchpad bug 1456073 in neutron "Connection to an instance with floating IP breaks during block migration when using DVR" [High,Confirmed]
15:07:49 <Swami> oleg was proposing to have the neutron team come up with a proposal and then we can approach the nova broader team to addin the respective hooks for the live migration.
15:08:02 <haleyb> Swami: you also started a discussion the -dev list, let me try and find the link to that too
15:08:04 <Swami> haleyb: carl_baldwin: did you take a look at the discusson.
15:08:18 <Swami> haleyb: yes I also started a discussion in the dev list.
15:09:40 <Swami> regXboi: hi, welcome back.
15:09:42 <carl_baldwin> Swami: I haven't
15:09:53 * regXboi wanders in and waves to the throng
15:09:59 <regXboi> happy new year all
15:10:14 <haleyb> http://lists.openstack.org/pipermail/openstack-dev/2015-December/082615.html
15:10:18 <Swami> carl_baldwin: no problem, you can take a look at the discussions that we had so far.
15:10:27 <haleyb> Swami: I did not look either as I've been out
15:11:19 <carl_baldwin> Swami: ok
15:11:23 <Swami> We need to bring the nova folks attention on this item.
15:11:59 <Swami> carl_baldwin: I did see your email yesterday regarding the nova_scheduler changes required for the routed_networks and you also mentioned that it might address some of the migration issues.
15:12:24 <Swami> carl_baldwin: I was not sure that covers the issue that we are talking about the Nova-Neutron notifiers for the live_migration.
15:12:35 <carl_baldwin> Swami: more like that it will have migration implications
15:12:53 <carl_baldwin> It doesn't
15:13:37 <Swami> carl_baldwin: I have also added some content in the "nova midcycle etherpad" for the nova-neutron notifiers.
15:14:13 <carl_baldwin> Swami: I need to find that
15:14:26 <carl_baldwin> I will be attending the mid cycle
15:14:27 <Swami> #link https://etherpad.openstack.org/p/mitaka-nova-midcycle
15:14:34 <carl_baldwin> Swami: thanks
15:15:12 <Swami> carl_baldwin: I will also try to join the nova meeting this thursday and will try to get the nova folks attention on this item.
15:15:52 <Swami> carl_baldwin: haleyb: regXboi: meanwhile we need to figure out what are the things that would be needed on the neutron side to make it to work.
15:16:28 <Swami> it would be great if you all can provide your feedback through the intial launchpad bug thread.
15:16:42 <carl_baldwin> Swami: will do
15:17:18 <Swami> I have also added couple of WIP patches to gerrit to address this in the neutron side.

15:18:25 <haleyb> Swami: and i see Paul Murray commented in the bug as well
15:18:48 <Swami> carl_baldwin: haleyb: yes I have also forwarded to Paul Murray about this issue.
15:19:43 <Swami> should we pull in the right folks to have a meeting to discuss this issue before the nova midcycle meetup.
15:21:46 <carl_baldwin> Swami: sounds fine
15:22:18 <Swami> carl_baldwin: thanks
15:22:57 <Swami> Ok let us continue our discussion and action items in the bug report. Just wanted to bring you all up to speed.
15:23:15 <Swami> let us move on to the next topic if you don't have any questions on this.
15:23:17 <haleyb> Thanks for pushing this along Swami

15:37:06 <Swami> This is the last bug for today and probably needs some attention.

15:37:11 <openstack> Launchpad bug 1365473 in neutron "Unable to create a router that's both HA and distributed" [Wishlist,In progress] - Assigned to Adolfo Duarte (adolfo-duarte)

15:38:42 <Swami> haleyb: back to you
15:38:49 <carl_baldwin> Swami: Thanks
15:39:19 <haleyb> #topic Gate Failures
15:39:52 <haleyb> The single-node DVR job is voting again (since 12/17)
15:40:19 <Swami> nice job
15:41:22 <Swami> haleyb: is there any new failures in gate with respect to the single node.
15:41:25 <haleyb> the patch to add tempest debugging has stalled, do we need to push that forward?
15:42:04 <Swami> haleyb: As I mentioned before, the pings are not consistently working with that patch.
15:42:12 <haleyb> Swami: the single-node has snuck up a bit in the past day, but it's trending downwards
15:42:20 <Swami> haleyb: I am not sure if that would be of much use if the pings are not working.
15:42:36 <Swami> haleyb: it might be due to the overall issue that we had with the gate this week.
15:43:42 <Swami> haleyb: I will try to do some more testing on the tempest debug patch in my local environment to check if the pings get through and then we can decide.
15:44:00 <haleyb> I am remembering a change from Oleg regarding port status but can't find the link, which could help with failures
15:44:39 <Swami> #link https://review.openstack.org/#/c/246898/
15:44:45 <Swami> is this the one that you are talking about.
15:46:01 <haleyb> I don't think so, and i was just looking at it
15:46:50 <Swami> #link https://review.openstack.org/#/c/253569/ - is this the one that you are looking for.
15:47:15 <haleyb> yes, thanks, that was the one
15:47:46 <haleyb> that's related to High priority https://launchpad.net/bugs/1522824
15:47:48 <openstack> Launchpad bug 1522824 in neutron "DVR multinode job: test_shelve_instance failure due to SSHTimeout" [High,In progress] - Assigned to Oleg Bondarev (obondarev)
15:48:04 <Swami> Yes we discussed this a while back.
15:49:15 <haleyb> Are there any other gate failure things to discuss?
15:50:08 <Swami> haleyb: don't think so, all our issues are now with the multinode and we have to wait till the migration issues are sorted out.
15:50:11 <Swami> we can move on.
15:50:31 <haleyb> #topic Performance/Scalability
15:51:24 <haleyb> i don't see Oleg, but there is one review listed
15:51:46 <haleyb> https://review.openstack.org/#/c/254837/
15:52:21 <haleyb> I will review that again
15:52:37 <Swami> he is not here today.
15:52:51 <haleyb> #topic Open discussion
15:53:19 <haleyb> Anything else?  Or you'll get 7 minutes back for fixing bugs :)
15:53:43 <Swami> I don't have any topics for today
15:55:34 <haleyb> Thanks for coming everyone, including the lurkers :)
15:55:36 <Swami> I think we can end this meeting.
