18:04:57 <SlickNik> #topic Review #147908: Try to gain some consensus on how to resolve the issues itemized in final review comment.
18:05:18 <dougshelley66> I added that item
18:05:22 <SlickNik> dougshelley66: Want to give folks a quick overview on what this is about?
18:05:50 <dougshelley66> the review is about relocating the mysql datadir to somewhere other than the root of a volume
18:05:57 <dougshelley66> which seems simple enough...
18:06:19 <dougshelley66> however the change potentially affected compatabilityu
18:06:29 <dougshelley66> so i went off to give it some more thought
18:06:33 <bartash> o/
18:06:40 <dougshelley66> over the weekend i posted some thoughts https://review.openstack.org/#/c/147908/
18:06:46 <dougshelley66> see the last reveiw comment
18:07:12 <dougshelley66> one question i had - does anyone know why the config.template is rendered on the task manager?
18:07:26 <dougshelley66> seems like it would be more natural to have the guest do it?
18:08:40 <SlickNik> dougshelley66: My guess is that this was done to keep the guest siimple and not have any template / rendering code on the guest.
18:08:46 <vgnbkr> dougshelley66, +1
18:10:07 <dougshelley66> i also wondered what people thought about my point #1?
18:10:09 <esmute> dougshelley66: is the purpose for this patch to have system folders like LOST+FOUND not appear as a database? If so, dont we have a way to configure this and ignore it?
18:10:19 <vgnbkr> Having the configs rendered in the taskmanager also casued issues for replication.
18:10:40 <dougshelley66> 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 <dougshelley66> georgelorch, could probably elaborate here
18:11:10 <dougshelley66> i believe the bug has a reference to a best practice article
18:11:21 <dougshelley66> the specific issue i hit was on resize after a restore, i beleive
18:11:29 <georgelorch> MySQL will 'think' any dir in the data dir is a database
18:11:30 <vgnbkr> In GTID mode, mysql won't come up with LOST+FOUND, even if trove "overlooks" it.
18:11:43 <SlickNik> #link http://www.percona.com/files/white-papers/preventing-mysql-emergencies.pdf
18:11:49 <esmute> GTID?
18:11:50 <SlickNik> ^ from the bug
18:11:51 <georgelorch> and a MySQL bestpractice is to never have your datadir be the root of a mount
18:12:14 <dougshelley66> esmute, GTID is the new mechanism used for replication
18:12:40 <SlickNik> 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 <dougshelley66> SlickNik, https://bugs.launchpad.net/trove/+bug/1370646
18:13:26 <vgnbkr> 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 <SlickNik> #link https://bugs.launchpad.net/trove/+bug/1370646
18:17:27 <SlickNik> 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 <SlickNik> dougshelley66: Seems like a problem that we should look into fixing.
18:18:05 <dougshelley66> SlickNik, sure - we could also kick it around in Seattle next week
18:18:12 <SlickNik> Just need to understand the options we have for the fix, and the benefits and drawbacks of each.
18:18:17 <SlickNik> That sounds like a plan.
18:18:38 <SlickNik> I will pencil it in to the agenda so we don't forget.
18:18:45 <dougshelley66> thanks
18:19:13 <SlickNik> Thank you (and Simon) for looking into this
18:19:18 <dougshelley66> np
18:19:45 <SlickNik> #topic Open Discussion
18:19:52 <dougshelley66> i have one item/request
18:20:04 <SlickNik> dougshelley66: go for it.
18:20:24 <dougshelley66> would there be some room in the Seattle agenda to add Scheduled Tasks, MariaDB and Metadata?
18:21:57 <dougshelley66> sorry for the last minute notice :)
18:22:13 <SlickNik> 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 <dougshelley66> SlickNik, sounds good thx
18:22:32 <georgelorch> 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 <vgnbkr> o/
18:23:17 <SlickNik> 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 <georgelorch> SlickNik, that would be great! Thank you!
18:23:41 <SlickNik> georgelorch: Will keep folks posted on that as soon as I have it set up.
18:23:41 <vkmc> SlickNik, +1
18:23:45 <vkmc> I was going to ask about it :)
18:23:48 <vgnbkr> (that's my hand up for an open item, btw)
18:23:48 <esmute> Go Hawks! :P
18:23:48 <vkmc> thanks
18:24:13 <SlickNik> vgnbkr: go for it
18:24:43 <SlickNik> #action SlickNik update the current agenda (TBD slot) with suggestions for new discussion items
18:24:46 <vkmc> are you going to use etherpad to outline the sessions? if so... where are those going to be published?
18:24:48 <vgnbkr> 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 <SlickNik> so I don't lose track of it.
18:25:54 <SlickNik> 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 <SlickNik> vkmc: The Sprint page has the schedule linked to the etherpad pages for the sessions
18:26:12 <vgnbkr> SlickNik, sure
18:26:15 <SlickNik> #link https://wiki.openstack.org/wiki/Sprints/TroveKiloSprint
18:26:45 <vkmc> cool, thanks!
18:27:19 <SlickNik> 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 <SlickNik> And then we can keep that updated with the items that come up during the actual discussions.
18:28:10 <vgnbkr> Anywhere in the schedule you don't have a topic, just put "drinking".
18:28:25 <georgelorch> +1
18:28:46 <SlickNik> heh
18:29:00 * georgelorch needs to remember to refill the keg :)
18:29:08 <SlickNik> Oh, I have a topic for open discussion as well.
18:29:17 <SlickNik> We have a new member on our HP Trove team.
18:29:54 <SlickNik> ashleighfarnham just joined us, and is currently getting up to speed with things.
18:30:11 <peterstac> welcome ashleighfarnham!
18:30:12 <dougshelley66> ashleighfarnham, Welcome!
18:30:24 <ashleighfarnham> hi everyone!
18:30:29 <vkmc> ashleighfarnham, welcome! :)
18:30:34 <esmute> Hello ashleighfarnham!
18:30:39 <SlickNik> I should say that ashleighfarnham is Ashleigh Farnham :)
18:30:47 <SlickNik> (hope I spelled that correctly)
18:31:33 <SlickNik> 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 <SlickNik> Any other items for Open Discussion?
18:33:16 <esmute> Cant wait to see you guys again.. and meet new faces too :)
18:33:40 <SlickNik> Ditto — Looking forward to next week!
18:34:30 <dougshelley66> Will we break for the Superbowl parade if the Hawks win?
18:34:51 <esmute> I think SlickNik has that added in the agenda
18:35:00 <nshah> They are not winning :-)
18:35:03 <esmute> Wednesday afternoonish.. i think
18:35:27 <georgelorch> I'm just curious how the Patriots are going to cheat their way out of this one :D
18:35:34 <SlickNik> 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 <esmute> 24-10 Seahawks!
18:36:29 <nshah> Envy is the worst vice… 15 years of success and counting… Go Pats!!! :-)
18:36:51 <SlickNik> And on that note.
