16:01:10 <geguileo> hi! o/
16:01:16 <eharney> hi
16:01:27 <DuncanT> Hi
16:01:31 <tbarron> hi
16:01:58 <e0ne> hi
16:02:25 <jungleboyj> Sorry everyone for the confusion last week about the meeting.
16:02:56 <jungleboyj> I should have gotten the etherpad updated and every time I went to update it I got interrupted.  So, thanks to who ever got that done.
16:03:30 <jungleboyj> Ok, I am guessing this is all we are going to have for this week so lets get started.
16:03:33 <Swanson> These things never happened under the old regime.
16:03:45 <jungleboyj> Swanson:  :-p
16:03:52 <smcginnis> :)
16:04:03 * jungleboyj hands the reigns to Swanson
16:04:27 <jungleboyj> #topic Announcements
16:04:31 * DuncanT attaches the reins to a passing truck
16:04:36 <smcginnis> Ha
16:04:41 * jungleboyj laughs
16:05:13 <jungleboyj> So, we have our review priorities:
16:05:17 <jungleboyj> #link https://etherpad.openstack.org/p/cinder-spec-review-tracking
16:05:41 <jungleboyj> A reminder to keep an eye on those because of our next agenda item:
16:05:58 <jungleboyj> Milestone 2 for Queens is coming up in just a couple of weeks.
16:06:06 <lhx_> hi
16:06:13 <lhx_> all
16:06:26 <jungleboyj> I know there have been updates to specs.  I need to take a look at those and see which ones can make it in before the Freeze.
16:06:55 <jungleboyj> I think there are a couple of drivers that need reviews to get merged.
16:07:22 <jungleboyj> Appreciate any help we can get to get those reviews done and things merged.
16:07:47 <jungleboyj> Any questions and comments there?
16:07:52 <smcginnis> Would be great if we didn't wait until the last week this time to do those driver reviews.
16:08:14 <jungleboyj> smcginnis:  Yeah, good point.
16:08:46 <jungleboyj> Hopefully my brain has recovered enough to start working on that kind of stuff today.  :-)
16:09:12 <jungleboyj> #topic Brief Overview of Sydney Summit
16:09:38 <jungleboyj> Sorry that we couldn't see more of you at the summit, but it was a long way to travel.
16:10:06 <jungleboyj> We had a great Upstream Institute session.  Got ~26 new people educated who were all eager to work on OpenStack.
16:10:29 <jungleboyj> The Cinder On-Boarding session was attended by 6 people.
16:10:56 <jungleboyj> Was glad to have some interest there and I got the session recorded so I will be posting that to our YouTube channel soon.
16:11:33 <tommylikehu> jungleboyj:  great!
16:11:55 <jungleboyj> Otherwise, from a Cinder Standpoint there wasn't a lot of technical content.  Feel like Summit is suffering as we feared it would when they changed the format.
16:12:23 <jungleboyj> Not a lot of technical content and the summit is turning into an opportunity for the people who are paying to come push their wares.
16:13:04 <lhx_> jungleboyj, could you show me the channel link?
16:13:25 <jungleboyj> The sessions that were about how OpenStack is being used and where it needs to go were nice though.
16:13:39 <jungleboyj> CERN's numbers of storage and compute needed in the future are insane.
16:14:03 <DuncanT> Are CERN using cinder yet?
16:14:27 <smcginnis> DuncanT: Yeah, they are.
16:14:29 <jungleboyj> DuncanT:  Yep, they do.
16:14:35 <jungleboyj> lhx_:  Here
16:14:40 <jungleboyj> #link https://www.youtube.com/channel/UCJ8Koy4gsISMy0qW3CWZmaQ/videos
16:14:48 <lhx_> jungleboyj, thanks :)
16:14:55 <jungleboyj> lhx_:  Welcome.
16:14:55 <Swanson> Like how many nodes are they using?
16:15:03 <jungleboyj> 300k
16:15:13 <jungleboyj> Swanson:  Cores
16:15:18 <jgriffith> :)
16:15:38 <Swanson> Neato.
16:15:38 <tbarron> with lvm, right?
16:15:42 * tbarron ducks
16:15:50 <jungleboyj> tbarron:  Ha ha.  CEPH.
16:15:58 <jgriffith> jungleboyj: and *others*
16:16:09 <jungleboyj> jgriffith:  You know what the others are?
16:16:15 <jgriffith> and that's not 200K cores of cinder BTW :)
16:16:21 <jgriffith> jungleboyj: some
16:16:37 <jgriffith> predominantly ceph
16:16:57 <jungleboyj> jgriffith:  Right, that is compute.  I am not sure how many storage nodes the have.  They just talking in PB of storage.
16:17:35 <jungleboyj> Anyway, jgriffith or smcginnis have anything to add from the summit?
16:18:24 <jungleboyj> *crickets*
16:18:38 <smcginnis> No, not really. Some good feedback sessions with operators, but nothing too noteworthy at this point.
16:18:54 <Swanson> Anyone have a vegimite sandwich?
16:18:57 <smcginnis> Some discussion of LTS releases going on. Or something along the lines of an LTS concepts.
16:19:03 <jungleboyj> smcginnis: Ok.  Cool.
16:19:20 <jungleboyj> smcginnis:  Yeah, I have seen that there is now a mail list thread on that.
16:19:47 <jungleboyj> Will be interested to see where that goes.
16:20:03 <jungleboyj> Swanson:  I didn't.  Had Crocodile and Kangaroo though.
16:20:35 <jungleboyj> #topic Update on Multi-attach after the Summit Session:
16:20:39 <Swanson> jungleboyj, Typical McDonalds, then.
16:20:44 <smcginnis> Anyone interested in the LTS proposals, brainstorming is being done here: https://etherpad.openstack.org/p/LTS-proposal
16:20:48 <jungleboyj> #link https://etherpad.openstack.org/p/sydney-cinder-nova-cp-multi-attach
16:21:04 <smcginnis> Mackies in Australia. And Burger King is Hungry Jacks.
16:21:15 <jungleboyj> #link https://etherpad.openstack.org/p/LTS-proposal
16:21:48 <jungleboyj> Had a relatively well attended session on Multi-attach.
16:22:01 <jungleboyj> Unfortunately there were not so many Operators there.
16:22:45 <jungleboyj> We presented what the design of Multi-attach currently is and didn't get negative feedback.
16:23:08 <jungleboyj> Agreement that we need good documentation as to how it works and would should/should not be done.
16:23:52 <jungleboyj> Agreement that boot from volume volumes will be read-only.
16:24:51 <jungleboyj> There was also discussion of a problem where you can attach the same volume to the same instance multiple times even when multi-attach is set to false.
16:25:10 <jungleboyj> The problem is due to code that needs to be in place for live migration.
16:25:45 <jungleboyj> Nova team is planning to hack in a fix for Queens to avoid the problem and in the future we may need to find a better solution.
16:26:14 <jungleboyj> Long story short, we are continuing to make good forward progress and no one at the sessions seemed to have notable concerns.
16:26:48 <jungleboyj> I think that was all that was of interest there.
16:27:07 <jungleboyj> #topic Open Discussion
16:27:26 <jungleboyj> One other thing.  We did have an office hours session at the Summit.
16:28:17 <jungleboyj> I had a chance to chat with aspiers about the Storage Based Death approach for HA / Fencing of nodes.
16:28:45 <jungleboyj> I helped provide some education on how Cinder works.  Think they had some bad assumptions.
16:29:07 <jungleboyj> What they are thinking for SBD definitely would not work for all storage backends.
16:29:48 <jungleboyj> They were going back to think about it more.  Something like Table Based Death using the database might be more realistic to work.
16:30:06 <smcginnis> Oh, I also wanted to mention the bugsmash is next week.
16:30:09 <smcginnis> #link http://lists.openstack.org/pipermail/openstack-dev/2017-October/123854.html
16:30:19 <jungleboyj> As we talked about it, however, I am not totally convinced that we can gain much from it.
16:30:28 <jungleboyj> smcginnis:  Oh, that is good to know.
16:30:39 <smcginnis> Cores, and really anyone who can help with reviews, please try to help look at those patches.
16:31:00 <smcginnis> Something to do while you're half comatose on the couch after turkey fest.
16:31:05 <tommylikehu> yeah
16:31:21 <jungleboyj> Do we have anyone from Cinder participating?
16:31:33 <smcginnis> tommylikehu: Are you going to attend that?
16:31:38 <tommylikehu> I will
16:31:47 <smcginnis> Great!
16:32:07 <jungleboyj> Great1
16:32:35 <jungleboyj> tommylikehu:  Please feel free to ping me as if there are reviews that need attention so that we can help make the bug smash productive.
16:33:34 <tommylikehu> jungleboyj: lol, the messages would keep coming at midnight:)
16:33:44 <jungleboyj> Thursday and Friday next week are a US holiday but I was planning to stay somewhat available.
16:33:53 <jungleboyj> tommylikehu:  :-)  I am used to it.
16:34:29 <jungleboyj> Any other topics for Open Discussion?
16:35:13 <jungleboyj> I guess related to the Bug Smash, does anyone have bugs that would be appropriate for the bug smash to address?
16:35:28 <jgriffith> jungleboyj: yes
16:35:54 <jungleboyj> jgriffith: Cool.  We had put together a list for the last bugsmash.
16:36:27 <jgriffith> jungleboyj: cool, I'll find it and add it to the list
16:36:40 <jungleboyj> jgriffith:  That would be great.
16:37:02 <jgriffith> https://bugs.launchpad.net/cinder/+bug/1732223
16:37:02 <openstack> Launchpad bug 1732223 in Cinder "cinder-manage volume delete doesn't work due to rpc versioning error" [Undecided,New]
16:37:57 <jungleboyj> jgriffith:  Unfortunately I don't have it in my list of etherpads.  We put it together at the end of the Boston summit.
16:38:18 <jungleboyj> I will go back and see if I can find where we put that list and send a note out to the mailing list.
16:38:32 <smcginnis> jungleboyj: Weren't we just tagging possible bugs with "bugsmash" or something like that?
16:38:59 <jungleboyj> Hmmm, that does sound familiar.  :-)
16:40:39 <jungleboyj> I will follow up on that and send a note to the ML.
16:41:43 <jungleboyj> smcginnis:  Yep, looks like that is what we did.  We still have 11 with that tag.
16:42:12 <jungleboyj> Just added jgriffith 's
16:42:27 <jungleboyj> So, if anyone else has candidates, please add that tag.
16:43:12 <jungleboyj> smcginnis:  Thanks for that topic!
16:43:17 <jungleboyj> Anything else from anyone?
16:43:57 <jungleboyj> I will take that as a no and we can wrap the meeting up early.
16:44:36 <jungleboyj> I am guessing a lot of people in the US will be on vacation next Wednesday, but lets still plan to meet for those who can make it.
16:45:09 <jungleboyj> Oh and incentive to get to Dublin, I finally have the new Cinder stickers!
16:45:22 <smcginnis> Woohoo
16:45:51 <jungleboyj> Class up your laptop with horse's ...
16:45:54 <jungleboyj> backend.
16:46:16 <jungleboyj> On that note ...
