| smcginnis | avishay: Hi | 13:08 |
| *** baumann has quit IRC | 13:08 | |
| avishay | sorry about the confusion in the review for list manageable - i was referring to this: http://eavesdrop.openstack.org/irclogs/%23openstack-meeting/%23openstack-meeting.2016-04-13.log.html#t2016-04-13T16:20:47 | 13:09 |
| avishay | when DuncanT said: "avishay: The move to core should probably be a different patch to your addition" | 13:09 |
| smcginnis | avishay: Ah, that was in reference to getting rid of the API extensions. | 13:10 |
| smcginnis | avishay: But all new API additions should be on v3 and with microversions. | 13:10 |
| DuncanT | Each extension can be moved in indemedently | 13:10 |
| avishay | I'm confused... | 13:10 |
| *** laughterwym has joined #openstack-cinder | 13:11 | |
| DuncanT | avishay: We want to move all the extensions into core | 13:12 |
| avishay | DuncanT: that i understand. but should i add these resources first, or later, or is it part of some effort to move them all? | 13:12 |
| smcginnis | avishay: New API additions will not be API extensions. | 13:13 |
| smcginnis | So I think the point was, that part of the discussion is a separate effort. | 13:13 |
| *** akerr has joined #openstack-cinder | 13:13 | |
| *** qeelee has joined #openstack-cinder | 13:13 | |
| DuncanT | avishay: I think it is reasonable to ask that you put up the patch to move the extension into core at the same time you add to it - the move isn't massively complex | 13:15 |
| *** asselin__ has joined #openstack-cinder | 13:15 | |
| *** qeelee has quit IRC | 13:15 | |
| avishay | DuncanT: I have no problem doing the patch. I just couldn't find any example in Cinder of microversions, or anything beyond what is in cinder/api/v3/router.py | 13:16 |
| DuncanT | https://review.openstack.org/#/c/278605 i sthe best example I know, though it might not be perfect | 13:17 |
| DuncanT | We haven't merged any new microversions yet | 13:17 |

| DuncanT | Ah, looks like I haven't run git fetch for a while :-) | 13:19 |
| avishay | So wouldn't it make sense to add the resource after, so that it won't bump the version twice? (once for adding the resources in the extensions, and another for adding the new actions?) | 13:19 |

| *** ndipanov has quit IRC | 13:23 | |
| scottda | avishay: Sure. You mean how to add a microversion? | 13:23 |
| avishay | scottda: I assume I need to start by adding a resource in cinder/api/v3/router.py? | 13:24 |
| scottda | avishay: For starters, here's the devref: http://docs.openstack.org/developer/cinder/devref/api_microversion_dev.html | 13:24 |

| scottda | The change will come in api/contrib/volume_manager | 13:29 |
| *** jwcroppe has joined #openstack-cinder | 13:30 | |

| openstackgerrit | Adriano Freires Rosso proposed openstack/cinder: Deprecating XML config file https://review.openstack.org/294076 | 13:30 |
| scottda | avishay: So yes, I think you are correct. | 13:30 |
| avishay | scottda: OK, and should this patch go in before my current one, or after? (i.e., two version bumps or one?) | 13:32 |
| avishay | scottda: I can put them both up now but want to know which should depend on which | 13:32 |
| scottda | avishay: You should version bump at the same time. Otherwise, a user will have access to this via the /v2 endpoint without using microversions, and that is not what we want. | 13:32 |
| scottda | avishay: And you should not have to change router.py | 13:33 |
| scottda | avishay: Oh, to move the extension to core. I'd have to look at that more closely... | 13:35 |
| avishay | scottda: right now the user can access these resources only via /v2. so the question is to allow accessing the resources with the existing actions via /v3 and then adding the new actions, or adding the actions to /v2 and then adding all the actions to /v3. | 13:36 |

| dalgaaf | Anyone around to review os_brick patch: https://review.openstack.org/#/c/300560/ ? | 14:24 |
| geguileo | ameade: Hi | 14:24 |
| geguileo | ameade: I read your reply, but I don't understand what you mean about this being an option to avoid having too many threads... | 14:25 |
| ameade | geguileo: I looked at the original patch trying to figure out why it is even a config option at the reasoning seemed to be to have it false when you have a lot of things deleting | 14:29 |
| ameade | otherwise i imagine it would just always do them in separate threads | 14:29 |
| ameade | I dont know if that is a legit problem or not | 14:30 |
| geguileo | ameade: It should not be a problem | 14:30 |
| ameade | but it does seem a bit odd to just spin up X threads | 14:30 |
| geguileo | ameade: Why is it odd? | 14:30 |
| geguileo | ameade: Imagine this scenario | 14:30 |
| geguileo | ameade: Your service is running | 14:30 |
| geguileo | And you have 20 ongoing delete operations | 14:31 |
| ameade | can that happen? | 14:31 |
| geguileo | When you start you want them to make sure they are actually deleting in the backend | 14:31 |
| geguileo | Why couldn't there be 20 delete operations? | 14:31 |
| geguileo | We don't have any restriction for that, do we? r:-?? | 14:32 |
| DuncanT | ameade: You can have an arbitrary number of ongoing deletes in theory | 14:32 |
| ameade | mm | 14:32 |
| DuncanT | ameade: And given how slow and CPU loaded backup service can get, pathalogical situations aren't actually that hard to hit | 14:33 |
| DuncanT | I can't remember why we put the default to False, but I remember I asked for the config option - sadly in the pre-channel-logging days which makes the answer hard to find | 14:34 |
| smcginnis | That patch just moves the threading up to the whole processing instead of internally to the delete loop. Or did I miss something? | 14:35 |
| geguileo | Probably because existing behavior was not to start receiving operations in the service until everything was cleaned up | 14:35 |
| DuncanT | sheel: ping | 14:35 |
| sheel | DuncanT: hi | 14:35 |
| geguileo | smcginnis: The patch will make deletes serially instead of in parallel | 14:35 |
| DuncanT | sheel: You were asking me about your microverisons patch? | 14:35 |
| sheel | DuncanT: I got reply from scottda ... "3.2" seems confusing | 14:36 |
| DuncanT | geguileo: It will also stop the startup being blocked by the deletes though | 14:36 |
| sheel | DuncanT: so changing that accordingly... | 14:36 |
| geguileo | DuncanT: But we can do that now just by changing configuration option | 14:36 |
| DuncanT | geguileo: That might have been why there was a config option though | 14:37 |
| DuncanT | geguileo: just trying ot think through the tenant visible behaviour difference | 14:38 |
| ameade | "backup service could not be found' is the error you get when all the backup services are 'down' | 14:38 |
| ameade | i think it should be up but not pick up requests until it's done, when this option is false | 14:39 |
| ameade | the tenant gets that error | 14:39 |
| DuncanT | That behaviour actually came after this patch I think. Requests used to just sit on the queue | 14:40 |
| DuncanT | (I dislike that behaviour, FWIW, I prefered things to get queued) | 14:40 |
| geguileo | ameade: Have you tried with the lastest master? | 14:40 |
| ameade | that's what queues are for lol | 14:40 |

| avishay | bswartz: smcginnis is special - in my client he's on top | 15:07 |
| smcginnis | bswartz: Typically specs first, but I just recently found out that's at least backwards from how Nova does it. | 15:07 |
| bswartz | oh you're right avishay! | 15:07 |
| * smcginnis feels special :) | 15:07 | |

| *** shausy has quit IRC | 15:08 | |
| smcginnis | bswartz: How does manila handle specs/bps? | 15:08 |
| bswartz | smcginnis: we don't have a specs repo and specs are done in wikis only if needed | 15:08 |
| bswartz | so we always start with a BP and then link the spec if necessary | 15:09 |
| *** jgregor has joined #openstack-cinder | 15:09 | |
| smcginnis | bswartz: Oh nice. That works well for you? | 15:09 |
| bswartz | well it's process-light, which makes me happy | 15:09 |
| smcginnis | bswartz: A little less of that pesky "process" I know you like so much. :) | 15:09 |
| bswartz | it has the downside of making it slightly harder to provide feedback on specs | 15:09 |
| smcginnis | So at least for us, BPs approval is basically saying, sure that looks like not a terrible idea. | 15:10 |
| bswartz | I'm asking about cinder because I want to contribute a feature to cinder | 15:10 |
| smcginnis | Then if it needs a spec we debate details there. | 15:10 |
| bswartz | okay | 15:10 |
| smcginnis | Nova does spec first I believe, then approves the BP once that's squared away. | 15:10 |
| smcginnis | bswartz: Awesome, anything cool you're looking to add? | 15:11 |
| *** julim has quit IRC | 15:11 | |
| bswartz | yes I want to make the scheduler smarter | 15:11 |

| bswartz | IMO the scheduler does pathological things in a lot of cases and the admin has to be careful to avoid those scenarios | 15:12 |
| smcginnis | bswartz: Ping me when you file the BP and I can take a look. | 15:12 |

| scottda | jgriffith: To test /v3 endpoint with cinderclient you can pull this patch: https://review.openstack.org/#/c/300028 | 15:40 |
| avishay | scottda: BTW, the link you sent to your github had: -H "OpenStack-Volume-microversion: 3.1" | 15:41 |
| scottda | jgriffith: To use microversions in cinderclient cherry-pick this on top: https://review.openstack.org/#/c/301941 | 15:41 |
| avishay | scottda: But that didn't work for me, this did: -H "OpenStack-API-Version: volume 3.1" | 15:41 |

| jgriffith | I'm looking through git now | 20:58 |
| jungleboyj | jgriffith: It was removed back in like January I think. | 20:58 |
| jgriffith | jungleboyj: no | 20:58 |
| jungleboyj | jgriffith: Reasoning was that it didn't work reliably. | 20:59 |
| jgriffith | jungleboyj: couldn't have been that long ago, I just built this machine last week | 20:59 |

| sbezverk | jgriffith ping | 21:29 |
| jgriffith | sbezverk: hi | 21:29 |
| sbezverk | jgriffith hi, how is it going? | 21:29 |
| sbezverk | jgriffith any ideas how to make this fix working for us ;-)?? | 21:29 |
| jgriffith | sbezverk: well... I was going to use steves line "I'm booked solid for the next 3 weeks" | 21:30 |
| jgriffith | sbezverk: but... | 21:30 |
| jgriffith | I am kind of in the middle of some things | 21:30 |
| sbezverk | jgriffith that is fine, we have a temp solution with Steve's version | 21:30 |
| jgriffith | sbezverk: I'm not sure how that can be used | 21:31 |
| jgriffith | sbezverk: I guess cinder doesn't regularly do things like delete so maybe that's why it's *ok* | 21:31 |
| jgriffith | sbezverk: I'm also not completely clear why that version I pushed fails still | 21:31 |
| jgriffith | I couldn't quite gather the problem from the comments | 21:32 |
| sbezverk | jgriffith got it, I guess we wil have to live with this evil until you guys figure out solid solution, without any solution we lose half of VMs | 21:32 |
| jgriffith | sbezverk: I'll try and look at it again tonight | 21:32 |
| jgriffith | sbezverk: I'm going to need your help though I think to understand which call exactly is failing (which method in the gettattr call that is) | 21:33 |
| sbezverk | jgriffith if you need me to setup debug session, just let me know | 21:33 |
| patrickeast | jgriffith: sbezverk was that the glance thing from last week? | 21:33 |
| sbezverk | patrickeast yes | 21:33 |
| sbezverk | patrickeast the solution you suggested is not used in kolla | 21:33 |
| *** dustins has quit IRC | 21:33 | |
| jgriffith | patrickeast: https://review.openstack.org/#/c/306756/ | 21:33 |
| patrickeast | :D which solution? using swift? | 21:34 |
| sbezverk | patrickeast instead glance have a list of api servers and clients need to check one by one for the image before failing.. | 21:34 |
| sbezverk | patrickeast no using image replicator | 21:34 |
| patrickeast | oh yea | 21:34 |
| patrickeast | that kind of sucks that it needs to potentially hit all the servers | 21:35 |
| patrickeast | but i guess if it works, it works | 21:35 |
| jgriffith | patrickeast: sbezverk I've been mulling over the comment about not actually needing the internal raise there | 21:35 |
| sbezverk | patrickeast I agree but it is the way it is :-) | 21:35 |
| *** diablo_rojo has quit IRC | 21:36 | |
| sbezverk | jgriffith it is better to check with Steve I did not get his exact implementation.. | 21:36 |
| sbezverk | I meant with sdake | 21:36 |
| jgriffith | sbezverk: well, I understood his first impl and it makes sense, until you try and do a "delete" call :( | 21:37 |
| jgriffith | which returns None | 21:37 |
| jgriffith | so his code caused that to call to raise an exception | 21:37 |
| jgriffith | I'm unclear on why my check of method being called results in the data get failure | 21:37 |
| jgriffith | *unless* it's the iterator on the download just reaching the end | 21:37 |
| jgriffith | hmmm | 21:38 |
| sbezverk | jgriffith to prove it I remove 'data' from the list and it started working | 21:38 |
| patrickeast | wasn't the problem that we were calling data and it returned None? | 21:38 |
| jgriffith | sbezverk: well, in that case :) | 21:38 |
| patrickeast | so we do expect it to do it sometimes | 21:38 |
| jgriffith | sbezverk: that's a significant help for me | 21:38 |
| smcginnis | sbezverk: Is that a valid configuration to have multiple nodes but not sync the images? | 21:39 |
| jgriffith | smcginnis: we could've had HA without all the patches DOH!!! | 21:39 |
| jgriffith | just don't sync things :) | 21:40 |
| *** jungleboyj has quit IRC | 21:40 | |
| sbezverk | @smcginnis yep, glance offers this along with the list of api servers | 21:40 |
| sbezverk | where you can find the image.. | 21:40 |
| jgriffith | I suppose I can remove data from that list... | 21:41 |
| jgriffith | I'm assuming that if the image isn't found we'll never get to the download part | 21:41 |
| jgriffith | unless there's a chance that it queries one server, then tries downloading from another in the middle of the sequence? | 21:41 |
| sbezverk | jgriffith right the final exception should be triggered only when all aip servers returned no image found.. | 21:42 |
| jgriffith | I guess that also introduces a narrow race | 21:42 |
| jgriffith | I'm willing to propose it, but I'd like some good reviews and hopefully some people will test it fully | 21:42 |
| jgriffith | it's early enough in the release cycle that I'm somewhat comfortable with that | 21:42 |
| smcginnis | This seems kind of hackish to do any of this on our end. | 21:44 |
| sbezverk | jgriffith From my side I will beat something out pf it ;-) | 21:44 |
| smcginnis | Either the admin needs to sync their nodes... | 21:44 |
| smcginnis | or Glance should have built in smarts to give us the right image no matter where it is. | 21:44 |
| jgriffith | smcginnis: I'm curious if Nova runs into this? | 21:45 |
| jgriffith | I don't quite understand how they couldn't | 21:45 |
| patrickeast | anywhere they ask for a glance image they should | 21:45 |
| smcginnis | jgriffith: Good point! | 21:45 |
| patrickeast | unless they already have code like this | 21:45 |
| jgriffith | patrickeast: nope | 21:45 |
| jgriffith | patrickeast: unless they're checking it somewhere else, which is possible | 21:45 |
| *** haplo37 has quit IRC | 21:46 | |
| *** sgotliv_ has quit IRC | 21:46 | |
| jgriffith | patrickeast: but the glance.py file is the same one I "leveraged" years ago | 21:46 |
| patrickeast | haha | 21:46 |
| patrickeast | jgriffith: gotcha | 21:46 |
| smcginnis | Hah, "leveraged". | 21:46 |
| jgriffith | patrickeast: although there's so much indirection with everyone's cleverness any more who knows | 21:46 |
| openstackgerrit | John Griffith proposed openstack/cinder: Retry when glance returns None on fetch https://review.openstack.org/306756 | 21:46 |
| patrickeast | jgriffith: true, plus they do a bunch of image caching too if i understand correctly | 21:46 |
| jgriffith | patrickeast: yeah, I just put that in my comment :) | 21:48 |
| sbezverk | jgriffith the reason glance does it this way is because it is file backend.. I suspect when backend will be swift, it will probably behave much bettwe | 21:48 |
| jgriffith | wondering if the cache avoids the issue | 21:49 |
| patrickeast | jgriffith: it would assuming you get the image on the first try | 21:49 |
| *** _alastor_ has joined #openstack-cinder | 21:50 | |
| patrickeast | jgriffith: same thing would happen with our image-volume cache | 21:50 |
| jgriffith | patrickeast: yeah | 21:50 |
| patrickeast | jgriffith: or even if you keep trying through the failures until you get one to work | 21:50 |
| patrickeast | jgriffith: then you are in business | 21:50 |
| jgriffith | sbezverk: oh... well that's an interesting point | 21:50 |
| jgriffith | patrickeast: yeah... maybe | 21:50 |
| jgriffith | patrickeast: seems to me the whole design is just flawed, but what do I know | 21:51 |
| *** sdake has quit IRC | 21:51 | |
| jgriffith | patrickeast: I see sbezverk 's point about if/when you're using an object store | 21:51 |
| jgriffith | that makes sense | 21:51 |
| patrickeast | jgriffith: yep | 21:51 |
| smcginnis | Looks like the nova code has changed a bit: https://github.com/openstack/nova/blob/master/nova/image/glance.py#L191 | 21:51 |
| patrickeast | jgriffith: we usually just tell folks to use swift to avoid this | 21:51 |
| jgriffith | I guess I think it's just crap to say "sure.. run as many G-servers as you like" | 21:51 |
| jgriffith | oh... psst.. btw, we're not worrying about silly things like synching them | 21:52 |
| patrickeast | no one really uses the file backend, right? right?! | 21:52 |
| jgriffith | yeah... just like nobody uses LVM | 21:52 |
| jgriffith | :) | 21:52 |
| patrickeast | lol | 21:52 |
| smcginnis | Looks like this was supposed to add a sync_images config option: | 21:54 |
| smcginnis | https://blueprints.launchpad.net/glance/+spec/glance-sync-image-across-regions | 21:54 |
| *** IlyaG has joined #openstack-cinder | 21:54 | |
| sbezverk | jgriffith please do not joke with things like that, you almost gave me a heart attack !! Nobody uses lvm?!?! | 21:54 |
| smcginnis | But no patch associated with that altho it says Complete. | 21:54 |
| *** mylu has quit IRC | 21:54 | |
| sbezverk | I spent almost 2 month make it working in docker | 21:54 |
| jgriffith | sbezverk: haah.. sorry, it's an old petpeave of mine | 21:54 |
| smcginnis | Oh, Obsolete. | 21:54 |
| jgriffith | sbezverk: people trying to tell me LVM is no good and nobody uses it | 21:55 |
| *** laughterwym has joined #openstack-cinder | 21:55 | |
| jgriffith | sbezverk: it's a completely false statement and show ignorance | 21:55 |
| sbezverk | jgriffith please do not listen to them! | 21:55 |
| smcginnis | So I still think we are trying to work around a Glance issue, and the right answer is to fix Glance. | 21:55 |
| jgriffith | sbezverk: nope | 21:55 |
| smcginnis | But us being more robust isn't a bad thing. | 21:55 |
| jgriffith | smcginnis: perhaps | 21:55 |
| jgriffith | smcginnis: but I do like the work Kolla is doing, and running LVM/iSCSI in containers is pretty kick ass | 21:55 |
| jgriffith | smcginnis: if this is the one thing that is screwing it up, and there aren't any real side-effects, I say do it | 21:56 |
| jgriffith | smcginnis: or worst case... make a config option to ignore it | 21:56 |
| jgriffith | default to "NO_IGNORE" | 21:56 |
| smcginnis | jgriffith: I'm certainly behind that! | 21:57 |
| openstackgerrit | Helen Walsh proposed openstack/cinder: EMC VMAX - Oversubscription support https://review.openstack.org/307499 | 21:57 |
| smcginnis | +1 to kolla for sure. | 21:57 |
| smcginnis | Just I think the issue needs to be pushed (or at least raised) with Glance. | 21:58 |
