If so, dont we have a way to configure this and ignore it? 18:10:19 Having the configs rendered in the taskmanager also casued issues for replication. 18:10:40 no - it is because the presence of the lost+found dir in the mysql data dir is bad and breaks some things 18:10:52 georgelorch, could probably elaborate here 18:11:10 i believe the bug has a reference to a best practice article 18:11:21 the specific issue i hit was on resize after a restore, i beleive 18:11:29 MySQL will 'think' any dir in the data dir is a database 18:11:30 In GTID mode, mysql won't come up with LOST+FOUND, even if trove "overlooks" it. 18:11:43 #link http://www.percona.com/files/white-papers/preventing-mysql-emergencies.pdf 18:11:49 GTID? 18:11:50 ^ from the bug 18:11:51 and a MySQL bestpractice is to never have your datadir be the root of a mount 18:12:14 esmute, GTID is the new mechanism used for replication 18:12:40 So it seems to me that we have two places we're trying to store this datadir value in, and that's proving to be an issue. 18:12:46 SlickNik, https://bugs.launchpad.net/trove/+bug/1370646 18:13:26 I think the real issue is that it is the guest which best knows it's environment, trying to configure guest parameters on the taskmanager will continue to cause issues. 18:14:40 #link https://bugs.launchpad.net/trove/+bug/1370646 18:17:27 dougshelley66: So I don't think we're going to solve this issue during this meeting. Can we discuss this offline, and propose a recommendation on what a fix for this would look like? 18:17:42 dougshelley66: Seems like a problem that we should look into fixing. 18:18:05 SlickNik, sure - we could also kick it around in Seattle next week 18:18:12 Just need to understand the options we have for the fix, and the benefits and drawbacks of each. 18:18:17 That sounds like a plan. 18:18:38 I will pencil it in to the agenda so we don't forget. 18:18:45 thanks 18:19:13 Thank you (and Simon) for looking into this 18:19:18 np 18:19:45 #topic Open Discussion 18:19:52 i have one item/request 18:20:04 dougshelley66: go for it. 18:20:24 would there be some room in the Seattle agenda to add Scheduled Tasks, MariaDB and Metadata? 18:21:57 sorry for the last minute notice :) 18:22:13 dougshelley66: Yes — we have a free slot on the agenda, and I plan to add those to it. I'm also looking at juggling around a couple of other slots so we can tackle some more of these organic issues. 18:22:28 SlickNik, sounds good thx 18:22:32 SlickNik and team, unfortunately, due to the SuperBowl taking place here in AZ on Sunday, I'm not able to attend Seattle next week, but I will be hanging around irc all week and will be available for any discussion via Hangout/Skype/whatever if I can be of any assistance to the topic. 18:22:52 o/ 18:23:17 georgelorch: I'm looking to have a hangoutonair going so that remote folks can view / take part in what's going on. 18:23:39 SlickNik, that would be great! Thank you! 18:23:41 georgelorch: Will keep folks posted on that as soon as I have it set up. 18:23:41 SlickNik, +1 18:23:45 I was going to ask about it :) 18:23:48 (that's my hand up for an open item, btw) 18:23:48 Go Hawks! :P 18:23:48 thanks 18:24:13 vgnbkr: go for it 18:24:43 #action SlickNik update the current agenda (TBD slot) with suggestions for new discussion items 18:24:46 are you going to use etherpad to outline the sessions? if so... where are those going to be published? 18:24:48 We will be posting a spec for the V2 replication stuff sometime this week. It would be good if anyone interested would have a look before next week. 18:24:53 so I don't lose track of it. 18:25:54 vgnbkr: Awesome. Can you send out a message in the IRC channel / dev list as a reminder to folks once it's posted please? 18:26:12 vkmc: The Sprint page has the schedule linked to the etherpad pages for the sessions 18:26:12 SlickNik, sure 18:26:15 #link https://wiki.openstack.org/wiki/Sprints/TroveKiloSprint 18:26:45 cool, thanks! 18:27:19 There's not much there at the moment, but I'm planning that folks (and me!) will put in a skeletal outline for each session to go over / keep track of what we're planning to discuss. 18:27:39 And then we can keep that updated with the items that come up during the actual discussions. 18:28:10 Anywhere in the schedule you don't have a topic, just put "drinking". 18:28:25 +1 18:28:46 heh 18:29:00 * georgelorch needs to remember to refill the keg :) 18:29:08 Oh, I have a topic for open discussion as well. 18:29:17 We have a new member on our HP Trove team. 18:29:54 ashleighfarnham just joined us, and is currently getting up to speed with things. 18:30:11 welcome ashleighfarnham! 18:30:12 ashleighfarnham, Welcome! 18:30:24 hi everyone! 18:30:29 ashleighfarnham, welcome! :) 18:30:34 Hello ashleighfarnham! 18:30:39 I should say that ashleighfarnham is Ashleigh Farnham :) 18:30:47 (hope I spelled that correctly) 18:31:33 From what I've seen, she's almost on her way to proposing her first patch, so you'll start seeing her name on gerrit soon as well! :) 18:32:35 Any other items for Open Discussion? 18:33:16 Cant wait to see you guys again.. and meet new faces too :) 18:33:40 Ditto — Looking forward to next week! 18:34:30 Will we break for the Superbowl parade if the Hawks win? 18:34:51 I think SlickNik has that added in the agenda 18:35:00 They are not winning :-) 18:35:03 Wednesday afternoonish.. i think 18:35:27 I'm just curious how the Patriots are going to cheat their way out of this one :D 18:35:34 Will send out more information on the -dev ML and will link it from the IRC channel and the wiki page as developments happen, so stay alert. 18:35:34 24-10 Seahawks! 18:36:29 Envy is the worst vice… 15 years of success and counting… Go Pats!!! :-) 18:36:51 And on that note. 18:36:54 #endmeeting
