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