| rluediger | when i create a new volume it stays in mode generating for hours or days | 12:08 |
| DuncanT | 'mode generating'? That isn't a cinder term (unless you're running in a none-english locale?) | 12:09 |
| *** jistr has quit IRC | 12:09 | |
| rluediger | DuncanT: on the other hand if i delete such hanging volumes i have to restart the tgt & cinder services on the block-storage node to get the volumes deleted | 12:09 |
| rluediger | DuncanT: sorry of course i mean creating | 12:10 |
| rluediger | DuncanT: <snip> | 6e389e98-009d-4953-8e72-5d6a33b6c2fa | creating | demo-volume1 | 1 | None | false | |</snip> | 12:10 |
| DuncanT | Ok, if you look in the API log, you should be able to find a line relating to that create. In that line, there will be a request id field. Grep for that request id in the scheduler log | 12:11 |
| *** jistr has joined #openstack-cinder | 12:12 | |
| rluediger | DuncanT: o.k. I'll chekc for it | 12:12 |
| DuncanT | The flow for create is api->scheduler->cinder-volume, and request id lets you follow the flow reasonably easily | 12:12 |

| *** Ilja has quit IRC | 12:34 | |

| MentalRay | hum | 12:46 |
| rluediger | meanwhile I've tested to restart the cinder-scheduler but nothing changed there is no entry with the same req-id as in the api log | 12:46 |
| DuncanT | rluediger: Ok, that looks like a perfectly normal create. That suggests you've got a config error somewhere. Are all your services running on one node or several? | 12:46 |
| *** shilpa_ has quit IRC | 12:47 | |
| rluediger | DuncanT: i have 3 nodes (VMWARE Fusion Machines) and heer you can find which services are running on which node http://paste.openstack.org/show/176805/ | 12:48 |
| rluediger | DuncanT: But we are facing the same problem in our test environment with physical nodes as well | 12:49 |

| smcginnis | DuncanT: Wondering if you've ever looked in to any of that. | 15:09 |
| DuncanT | smcginnis: Yeah, I've a couple of links openned from the discussion, not yet read | 15:09 |
| smcginnis | DuncanT: So not something you've tried out? | 15:09 |
| DuncanT | smcginnis: We have internal (on cloud) apt mirrors I use, and I use a git object cache | 15:09 |
| smcginnis | DuncanT: Nice! | 15:09 |
| smcginnis | DuncanT: I'm probably going to try to set something up. I'll share whatever I find. Maybe not too valuable for you since you have local mirrors. | 15:10 |
| smcginnis | DuncanT: But could be. | 15:10 |
| DuncanT | I don't (yet) do any pip/pipi cache stuff, because when I tried it proved to be an epic pain in the ass | 15:10 |

| smcginnis | DuncanT: That was my first thought, but not sure if it would cache the way we would need it to. | 15:12 |
| smcginnis | DuncanT: Not a squid expert (or even an advanced novice) by any means though. | 15:12 |
| DuncanT | I set it up and looked at the cache hit/miss stats after a bunch of identical runs, they were terrible. After that I gave up on that approach. Would love to know why it doesn't work | 15:13 |
| *** leopoldj has quit IRC | 15:13 | |
| DuncanT | My total knowledge came from two how-to's ;-) | 15:13 |
| smcginnis | Then you're twice as knowledgable than me. | 15:13 |

| jgriffith | e0ne: yep | 15:21 |
| e0ne | :( | 15:21 |
| DuncanT | jgriffith: You might find that paste link interesting too... git clone cinder in ~2 seconds | 15:21 |
| smcginnis | DuncanT: I see, so you just prep the image with a cache at the time? So when it's used just has to pull the latest? | 15:21 |
| jgriffith | DuncanT: I ran into problems with that | 15:22 |
| jgriffith | DuncanT: but might be that I set something up wrong | 15:22 |
| jgriffith | DuncanT: it seemed to run into hiccups figuring out when it actually needed to pull | 15:22 |
| e0ne | jgriffith: what is your steps to reproduce this issue? | 15:22 |
| DuncanT | smcginnis: When it pulls latest, it generally has far less to pull so it works faster | 15:22 |
| jgriffith | e0ne: just setup devstack, and run the tempest volume tests | 15:23 |
| DuncanT | jgriffith: I've not noticed any problems, but I'm not running anything in anger | 15:23 |
| smcginnis | DuncanT: Yeah, I would think it should help. | 15:23 |
| jgriffith | DuncanT: Yeah, quite possible I screwed somethign up | 15:23 |
| smcginnis | DuncanT: That delta should be fairly small if it's a recent image. | 15:23 |
| jgriffith | DuncanT: OR... I use HUB and had some weirdness with it ALWAYS cloning from local if/when avaialable | 15:24 |
| jgriffith | maybe that was related? | 15:24 |
| DuncanT | smcginnis: Doing thin checkouts or whatever git calls them should give a similar performance boost TBH, but I like being able to look at history | 15:24 |
| DuncanT | HUB? | 15:24 |
| jgriffith | DuncanT: I'll have to try it out, would be immensely helpful | 15:24 |
| smcginnis | DuncanT, jgriffith: I think I may know what the issue with this is. | 15:24 |
| smcginnis | IIRC, git cache is keyed on the server. | 15:24 |
| jgriffith | DuncanT: oh yes.. https://github.com/github/hub | 15:24 |
| smcginnis | So if you have your local mirror you always pull from the same host. | 15:25 |
| DuncanT | smcginnis: My cache directory has a giant mess of remotes, so that seems reasoanble | 15:25 |

| e0ne | jgriffith: just to clarify that we are on the same page: do you get lockev lvm and stacktrace in syslog after trying to remove snapshots? | 15:27 |
| jgriffith | e0ne: so I just do "tox -e all -- volume" | 15:27 |
| jgriffith | e0ne: al the tests will pass | 15:27 |
| jgriffith | e0ne: but check out the slow list.. and then dig in to c-vol log :( | 15:27 |
| e0ne | jgriffith: or just you're working on a very slow lvm commands | 15:27 |

| jgriffith | e0ne: it very well could be | 15:28 |
| jgriffith | DuncanT: yeah, I like it... but I don't really exploit all of the cool features it has | 15:29 |
| emaisne | Hi, does anyone know which backend is used for the automized tempest tests?? e.g. https://review.openstack.org/#/c/153033/ | 15:29 |

| jgriffith | DuncanT: tab completion and abbreviated cloning are all I really use | 15:29 |
| DuncanT | jgriffith: I've dozens of minor patches to github projects sat around in my source directory | 15:30 |
| e0ne | emaisne: it should be lvm | 15:30 |
| DuncanT | jgriffith: Because I'm too lazy to figure out pull requests | 15:30 |
| jgriffith | DuncanT: even just things like "git browse" are handy | 15:31 |

| *** jwang has joined #openstack-cinder | 18:28 | |
| thingee | patrickeast: just work on it. I'll ask jgriffith for a +2 on the spec as well. I'll target it for k-3 after that. | 18:29 |
| patrickeast | thingee: ok cool | 18:29 |
| thingee | would also like hemna to give a +1 since I know he has interest in this | 18:29 |
| flip214 | hemna: any update on the transport driver multiplicity? Brick or john griffiths' target driver abstraction, what is the way to go? | 18:30 |
| thingee | jungleboyj: did I see right that the systemz is sponsored in nova? | 18:31 |
| jungleboyj | Yes. I think they have a decent chance of making it. | 18:32 |
| *** alecv has joined #openstack-cinder | 18:32 | |
| jungleboyj | kaufer: +2. Looks good to me. | 18:33 |
| jungleboyj | need to get hemna s input. | 18:33 |
| kaufer | thingee: Sorry was away, thanks! | 18:33 |
| kaufer | jungleboyj: Thanks, my only concern was with the constants in in the filter for 'replication_status' | 18:33 |
| kaufer | jungleboyj: The DB filtering doesn't support something like 'replication_status'!='disabled' so I had to provide all of the valid values, which I pulled out of your spec, hopefully I covered them all | 18:34 |
| thingee | winston-d: can you have a look at this review you participated in? It's blocking a couple of bps from being merged https://review.openstack.org/#/c/141868/10 | 18:35 |
| jungleboyj | kaufer: Ok, if you got them from my Spec then you should be good. | 18:35 |

| thingee | patrickeast: also multipath enhancement with pure | 18:42 |
| thingee | rhagarty: flash cache support. are we still looking good to have the code posted before march 1st, passing jenkins, not marked as wip? | 18:43 |
| thingee | xyang1, hemna: so I think this code could be done better. https://review.openstack.org/#/c/144561/11/cinder/consistencygroup/api.py | 18:45 |
| thingee | xyang1, hemna: we go from string -> list -> string | 18:45 |
| thingee | :) | 18:45 |
| jgriffith | flip214: what do you mean? | 18:45 |
| patrickeast | thingee: sry was afk for a min, yea i have code for them right now just waiting for the dependent changes to go in first so they will actually work | 18:45 |
| jgriffith | flip214: the target stuff isn't in brick any longer | 18:45 |
| jgriffith | flip214: whether it should be or not is a whole different question :) | 18:46 |
| xyang | thingee: suggestions for improvement are welcome | 18:46 |
| thingee | xyang1, hemna: I haven't looked to see if the potential race conditions I raised in the previous patch sets were addressed, but I'm a bit hung up on that. | 18:46 |
| flip214 | jgriffith: I'd like to know (for the DRBD-for-Nova thing) whether your target abstraction, brick, or whatever else is the right way to go. | 18:47 |
| xyang | thingee: on which? | 18:47 |
| flip214 | apart from 2 lines on IRC (from you) I haven't got _any_ feedback... | 18:47 |
| jgriffith | flip214: so on the nova side you need to deal with the initiator piece | 18:47 |
| jgriffith | flip214: which means it needs to be in brick | 18:47 |
| thingee | xyang: we talked on google hangout about them. | 18:47 |
| jgriffith | flip214: eventually | 18:47 |
| thingee | xyang: you said you would have to do some research | 18:47 |
| jgriffith | flip214: it's part of what hemna wants to solve | 18:48 |
| xyang | thingee: sorry, I thought we talked about the 2nd patch. I don't know which one you are referring to now | 18:48 |
| flip214 | jgriffith: well, all that got moved to K anyway... so it's not that important anymore. | 18:48 |
| jgriffith | flip214: currently you need initiator work in /cinder/brick/initiators as well as in Nova | 18:48 |
| kaufer | jungleboyj: So some are here, but it seems that 'copying' is missing: https://github.com/openstack/cinder/blob/master/cinder/replication/api.py#L35-L36 | 18:48 |
| jgriffith | flip214: we're in K :) | 18:48 |
| flip214 | just thinking that the 3 ways that are in https://github.com/LINBIT/cinder/tree/drbd-for-nova are bad for the reviewer, and my health. | 18:48 |
| jgriffith | flip214: you mean L? | 18:48 |
| *** jkremer has joined #openstack-cinder | 18:48 | |
| flip214 | sorry, got moved to _after_ K, ie. L. | 18:48 |
| hemna | in another meeting | 18:48 |
| hemna | sorry guys | 18:48 |
| jgriffith | flip214: looking | 18:49 |
| hemna | thingee, yes I'm planning on brick extraction in K | 18:49 |
| flip214 | thank you... | 18:49 |
| thingee | xyang: we did. I raised in the patch set though to you over google hangout about some race conditions. You weren't sure and said you would have to research into the problems I raised. | 18:49 |
| hemna | thingee, os-brick landed. | 18:49 |
| jgriffith | flip214: wait... what am I looking at exactly? | 18:49 |
| kaufer | jungleboyj: Maybe a complete list could be in that module, then the period task filtering code could just reference that and remove 'disabled' | 18:49 |
| hemna | thingee, I'm working on updating the docs for os-brick so we can do a release of it. | 18:49 |
| hemna | then update requirements.txt | 18:49 |
| flip214 | jgriffith: the remaining question is whether the DRBD transport functions should stay in the drbd cinder driver, or be relocated to brick. | 18:49 |
| jgriffith | flip214: says DRBD for nova, it's Cinder | 18:49 |
| hemna | then get my WIP cinder patch out of WIP | 18:50 |
| jungleboyj | kaufer: That doesn't sound like a bad idea in case that changes in the future. | 18:50 |
| flip214 | jgriffith: yes. My question is about cinder. | 18:50 |
| jgriffith | flip214: can you specify what you mean by "transport functions" | 18:50 |
| flip214 | the nova part is ~60 lines, no problem there. | 18:50 |
| jgriffith | flip214: which ones specifically | 18:50 |
| jgriffith | and I can answer that maybe :) | 18:50 |
| flip214 | initiate_connection, ensure_export, create_export, ... | 18:50 |
| kaufer | jungleboyj: Thoughts on if I should also tackle that in my patch? | 18:50 |
| flip214 | jgriffith: https://github.com/LINBIT/cinder/blob/drbd-for-nova/cinder/volume/drivers/drbdmanagedrv.py#L494 and below... | 18:51 |
| jgriffith | flip214: that all goes under cinder/volume/targets/ | 18:51 |
| flip214 | the first functions use your Target Driver (iSCSI), the ones below are used for the DRBD protocol. | 18:51 |
| jgriffith | flip214: if your driver needs/wants to override methods that are in iscsi target driver that's cool | 18:51 |
| jungleboyj | Hmmm, kind-of a separate change, but closely related. I am fine with lumping that in. | 18:52 |
| jungleboyj | hemna: ^^ ? | 18:52 |
| hemna | jungleboyj, which ? | 18:52 |
| jungleboyj | kaufer s question. | 18:52 |
| jgriffith | flip214: seems like what you have is good to me | 18:52 |
| jgriffith | flip214: not sure of the question | 18:53 |
| *** krtaylor has joined #openstack-cinder | 18:53 | |
| *** gary-smith has quit IRC | 18:53 | |
| jgriffith | flip214: just change the _DRBD ones to actually override the ones in the base target driver | 18:53 |
| flip214 | jgriffith: my question was the same as in my email from january... is that okay, or should I move the DRBD transport functions into the transport/ directory? upon which you answered, you agree with me. | 18:53 |
| jgriffith | flip214: I can post an example of how I did this in my SolidFire driver | 18:54 |
| jgriffith | flip214: I did not make a seperate driver in volume/targets | 18:54 |
| flip214 | jgriffith: if the DRBD transport is chosen, the functions are already monkeypatched. | 18:54 |
| jgriffith | flip214: I created the class in my driver file | 18:54 |
| thingee | hemna: understood you have plans for K. :) The question though is will we see something ready this week. I mentioned at the midcycle meetup I wanted this early in K-3. | 18:54 |
| hemna | thingee, https://review.openstack.org/#/c/155552/ | 18:55 |
| hemna | thingee, https://review.openstack.org/#/c/156863/ | 18:55 |
| flip214 | jgriffith: okay. thanks, I believe to know the direction Cinder wants to take now. | 18:55 |
| thingee | that's wip though. I want to start reviewing something for merge. | 18:55 |
| hemna | how is that for starters? | 18:55 |
| jgriffith | flip214: https://gist.github.com/j-griffith/c22cfc9e7c7695b93549 | 18:56 |
| thingee | because we're blocking multipath stuff, etc | 18:56 |
| hemna | I should be able to finish up the docs changes for os-brick today....if I can get out of meetings | 18:56 |
| thingee | hemna: just send kmartin to all of them for you | 18:56 |
| jgriffith | flip214: of course you may or may not need more than "pass" for the impl's :) | 18:56 |
| hemna | thingee, at some point today I wanted to chat with you and jaypipes about multiattach as well. | 18:56 |
| flip214 | jgriffith: my implementation now takes the "iscsi_helper" config option to distinguish... | 18:56 |

| xyang | thingee: the race condition is probably in the 2nd patch, not in this one | 19:00 |
| thingee | xyang: ah you might be right | 19:00 |
| thingee | xyang, DuncanT: so with regards to cinder objects.... | 19:00 |

| *** EmilienM|afk is now known as EmilienM | 19:02 | |
| thingee | xyang: not 2nd patch, completely separate | 19:02 |
| thingee | xyang: I think that's where I was noticing potential race issues | 19:02 |
| thingee | xyang: is that still planned for k? | 19:02 |
| *** kaufer has quit IRC | 19:02 | |
| xyang | thingee: ok, no problem. I'm still planning for it, just takes more time | 19:02 |
| leeantho | thingee, yes, I'll be removing the WIP tag from that patch soon. I was waiting for the next version of hplefthandclient to be available on PyPi before removing it | 19:02 |

| thingee | xyang: ugh, ok | 19:04 |
| *** bswartz has quit IRC | 19:04 | |
| thingee | xyang: I've also been testing the patch myself | 19:04 |
| xyang | thingee: ok, if I get my setup fixed, I'll test it | 19:05 |
| thingee | xyang: thanks | 19:05 |
| xyang | thingee: np | 19:05 |
| thingee | xyang: hopefully we'll get an update on xtremeio patch soon so we can merge that | 19:05 |
| xyang | thingee: i have a question regarding that | 19:05 |
| DuncanT | Thingee: I added a field to the db manually, and nothing broke. I changed the type of a field, and was able to write the adaptor in the snapshot object and the code didn't care | 19:05 |
| thingee | DuncanT: that's wonderful news | 19:06 |
| xyang | thingee: is there a way to override a default value in cinder.conf? | 19:06 |
| thingee | xyang: yes | 19:06 |
| xyang | thingee: other than changes cinder.conf | 19:06 |
| DuncanT | thingee: It is hardly extensive testing, but it is enough to make me think it is at least a great start. We won't know for sure until we try to use it in anger | 19:06 |
| thingee | xyang: https://github.com/openstack/oslo.config/blob/master/oslo_config/cfg.py#L2014 | 19:07 |
| DuncanT | thingee: Multi-attach will be a great workout for it, since it will be making some quite major schema changes | 19:07 |

| kaufer | DuncanT: I was trying to find the base class that defines that function in order to understand what the expected signature should be, I found that not all drivers implement the 'refresh' as a kwarg and am curious if that is a bug? | 21:23 |

| DuncanT | kaufer: Not sure, sorry. Check the code in cinder/volume/manager.py to see if it ever actually gets called with refresh actually set I guess | 21:31 |
| *** Yogi1 has joined #openstack-cinder | 21:31 | |
| DuncanT | kaufer: I suggest implementing refresh for now, it's an interesting question though | 21:32 |
| *** jordandh has joined #openstack-cinder | 21:32 | |
| *** jungleboyj has joined #openstack-cinder | 21:33 | |
| kaufer | DuncanT: I pushed some code that contained "self.driver.get_volume_stats()" assuming that refresh would default to False, but that failed in the CI since 7 drivers implemented the function as "def get_volume_stats(self, refresh)", while all of drivers implemented as "def get_volume_stats(self, refresh=False)" | 21:34 |
| kaufer | DuncanT: I planned on creating a bug to address the 7 drivers that didn't implment refresh as a kwarg, but wanted some feedback first | 21:35 |
| jgriffith | kaufer: DuncanT FYI the only place that's called externally that I remember is volume/manager | 21:38 |
| jgriffith | which sets refresh to "True" | 21:38 |
| jgriffith | and must to work correclty | 21:38 |
| jgriffith | correctly even :) | 21:38 |
| jgriffith | kaufer: but yeah, the fact that others didn't implement the kwarg at all is bad bad bad | 21:39 |
| kaufer | jgriffith, DuncanT: bug and fix to add the kwarg to the other drivers is on the way | 21:39 |
| jgriffith | kaufer: sweeet! | 21:39 |

| *** lcurtis has quit IRC | 22:00 | |
| jgriffith | kaufer, looks like everybody had it correct except HP | 22:02 |
| jgriffith | although I think some might be missing the call altogether :( | 22:02 |
| DuncanT | If it is always called with refresh=True, in L should we clean it up to get rid of the args all together? I never saw the point of it TBH | 22:03 |
| jgriffith | DuncanT: so some were using it internally as well and toggling that (I thought) | 22:04 |
| jgriffith | DuncanT: seems like it might be valid, but I agree, if it's not called anywhere seems pointless to have it | 22:04 |
| jgriffith | DuncanT: let somebody readd if they need it in the future :) | 22:05 |
| DuncanT | jgriffith: I'll file a bug, and patch all the drivers early in L. | 22:05 |
| DuncanT | jgriffith: I suspect it is a hold-over from copying hypervisor stats calls from nova | 22:06 |
| smcginnis | DuncanT: Didn't kaufer just do that? | 22:06 |
| jgriffith | DuncanT: works for me, assuming like I said nobody leverages it internally | 22:06 |
| jgriffith | DuncanT: oh.. interesting | 22:06 |
| *** lcurtis has joined #openstack-cinder | 22:06 | |
| DuncanT | smcginnis: He filed a bug saying not everybody implements it as a kwarg | 22:06 |
| jgriffith | smcginnis: DuncanT 's talking about just removing the kwarg altogether | 22:06 |
| smcginnis | jgriffith: Only a handful. I won't name names. | 22:06 |
| DuncanT | smcginnis: I'm talking about getting rid of the arg completely | 22:06 |

| DuncanT | kaufer: I've +2'd your patch since I suspect mine will cause people to complain | 22:12 |

| kaufer | DuncanT: Please see my change here: https://review.openstack.org/#/c/154673/7/cinder/volume/manager.py | 22:12 |
| smcginnis | jgriffith, DuncanT makes sense to me. If it can be simplified, great. | 22:13 |
| kaufer | DuncanT: That's how I found this, I was originally just invoking get_volume_stats() | 22:13 |
| *** esker has joined #openstack-cinder | 22:13 | |
| *** esker has quit IRC | 22:13 | |
| kaufer | DuncanT: Maybe I should instead have that set to True? | 22:13 |
| DuncanT | kaufer: We can just cache that value in the manager during the normal call, rather than calling into the driver again | 22:13 |
| DuncanT | kaufer: Or, since it is just once during init, we can just do True, yeah | 22:15 |
| kaufer | DuncanT: Oh, so I shouldn't call into the driver again to get the 'replication_status' value? | 22:15 |
| DuncanT | kaufer: At init time, there's probably no harm in calling in with True | 22:16 |
| *** Yogi11 has joined #openstack-cinder | 22:16 | |
| jgriffith | DuncanT: +1 | 22:16 |
| jgriffith | forgot that's all cached in the mangaer | 22:16 |
| jgriffith | manager even :) | 22:16 |
| kaufer | DuncanT: I set it to refresh=False since the driver was just initialized and I didn't think a refresh would be necessary | 22:16 |
| DuncanT | kaufer: At that point, it has never been called, so most drivers will be doing a refresh anyway until they do it in their own init | 22:17 |
| jgriffith | kaufer: there's a "host_stats" or something like that in there that you could just use, no? | 22:17 |
| *** Yogi1 has quit IRC | 22:17 | |
| DuncanT | kaufer: You should probably make https://review.openstack.org/#/c/154673/ depend on https://review.openstack.org/#/c/157165/ too, it'll make the CI systems happier if nothing else | 22:17 |

| kaufer | jgriffith: Ok, seems like we need to call into the driver to get it, so then it's just it should be refresh=True or False | 22:29 |

| Sam-I-Am | hello | 23:43 |
| sigmavirus24 | hey thingee we met at PyTN and I thought I'd introduce you to Sam-I-Am who's a coworker having issues with Cinder + Ceph | 23:43 |
| rhe00 | thingee: how often do you want status updates on ongoing CI work? | 23:43 |
| Sam-I-Am | well, i provide a lot of support in #openstack and a particular bug keeps coming up | 23:44 |
| sigmavirus24 | Sam-I-Am: has a bug that multiple people have run into so I thought I'd point him towards you :) | 23:44 |
| thingee | rhe00: anytime you got something interesting to tell me. I look at third party ci meetings with asselin and anteaya to gauge participation as well. | 23:44 |
| Sam-I-Am | trying to figure out if theres any way to get it some attention for kilo | 23:44 |
| thingee | rhe00: how are things going? | 23:45 |
| thingee | sigmavirus24, Sam-I-Am: hello! | 23:45 |
| rhe00 | thingee: I have been struggling for two weeks now. hit every bug, gotcha, configuration issue on the planet | 23:45 |
| sigmavirus24 | o/ | 23:46 |
| thingee | rhe00: I hear that. This is what I was talking about at the midcycle meetup. | 23:46 |
| Sam-I-Am | https://bugs.launchpad.net/cinder/+bug/1348811 | 23:46 |
| openstack | Launchpad bug 1348811 in Cinder "RBD + Nova migration fails because imports an existing disk" [High,Confirmed] | 23:46 |
| rhe00 | so I am pretty frustrated but trying to move forward | 23:46 |
| thingee | rhe00: well there are options as you know. I know you've been talking with patrickeast for help too | 23:46 |
| thingee | rhe00: and patrickeast apparently got things working pretty quickly | 23:46 |
| thingee | jbernard: ^ | 23:47 |
| patrickeast | rhe00: if you are stuck on any of the config stuff feel free to bug me | 23:47 |
| *** ebalduf has quit IRC | 23:47 | |
| thingee | Sam-I-Am: jdurgin and jbernard are who you want to talk to. I don't work on the ceph driver anymore, but they would be able to help with that part | 23:47 |
| *** ho has joined #openstack-cinder | 23:47 | |
| rhe00 | patrickeast: right now I am stuck on the publickey issue when nodepool is trying to login to the node to configure it | 23:47 |
| Sam-I-Am | thingee: cool, thx. whats the best time/way to reach them? | 23:48 |
| anteaya | rhe00: posting stacktraces on paste.o.o really helps us to understand where you are | 23:48 |
| thingee | Sam-I-Am: I'm surprised josh durgin is not around right now, but he's on around 10 PST | 23:49 |
| thingee | not sure about jbernard | 23:49 |
| patrickeast | rhe00: ah yea, the keys are kind of a pain, basically you just need to make sure all of them match up from the configurations | 23:49 |
| Sam-I-Am | thingee: thx | 23:49 |
| patrickeast | rhe00: and by match up i mean | 23:49 |
| thingee | I have been noticing bugs are building up on the rbd driver though https://bugs.launchpad.net/cinder/+bugs?field.tag=rbd | 23:49 |
| patrickeast | rhe00: use the same key for all the nodepool stuff | 23:49 |
| sigmavirus24 | thanks thingee | 23:50 |
| Sam-I-Am | thingee: i think because its becoming more popular? | 23:50 |
| thingee | I will be meeting with sage (creator of ceph) himself this week...I was going to poke him to put a resource to help with the build up of bugs I've been noticing | 23:50 |
| thingee | Sam-I-Am: most definitely | 23:50 |
| thingee | Sam-I-Am: I just don't want them to forget about us :) | 23:50 |
| rhe00 | patrickeast: I do use the same key. are we supposed to set up an ubuntu user and a jenkins user for nodepool or just a jenkins user? not quite clear on which user nodepool is trying to use when it hits the publickey auth failure | 23:51 |
| rhe00 | patrickeast: I thought it would use the user specified in the nodepool.yaml file, but there is a comment in there somewhere about an ubuntu user as well | 23:51 |
| patrickeast | rhe00: yea, so this keypair needs to be in your openstack provider https://github.com/patrick-east/os-ext-testing-data/blob/master/etc/nodepool/nodepool.yaml.erb#L34 and the images need to be able to use it | 23:53 |
| patrickeast | either through the openstack key injection magic, or pre-configured | 23:53 |
| thingee | patrickeast: thanks for helping :) | 23:53 |
| patrickeast | if you are using the ubuntu cloud images it should set it up for you as long as the keypair is setup | 23:53 |
| patrickeast | and the name matches* | 23:53 |
| patrickeast | thingee: np | 23:53 |
| rhe00 | patrickeast: one more question. how much space do you allocate for the disk on the slave node? I read somewhere that I should have 40GB of disk space, but that seems like an awful lot. Had to bind mount myself out of trouble as nova ran out of space in the instances folder on local disk. | 23:54 |
| patrickeast | rhe00: sec, checking what i made for my flavor | 23:54 |
| asselin | rhe00, ours are 'large' flavor | 23:55 |
| patrickeast | devstack-node88192MB40GB0GB4096MB | 23:55 |
| patrickeast | so 4gb swap and 40 gb root | 23:55 |
| rhe00 | asselin: that's 80 GB of hard drive, right? | 23:55 |
| asselin | i need to check | 23:55 |
| rhe00 | patrickeast: ok | 23:55 |
| asselin | nova devstack large :) | 23:55 |
| *** jwcroppe has quit IRC | 23:56 | |
| *** asmith_brcd has quit IRC | 23:56 | |
| patrickeast | i had to limit the disk space a bunch since our initiators don’t have very much local storage | 23:56 |
| *** jwcroppe has joined #openstack-cinder | 23:56 | |
| asselin | yes 80GB | 23:56 |
| *** jordandh has joined #openstack-cinder | 23:56 | |
| patrickeast | in the longer term i want to add support to nodepool to use volumes on the flash array | 23:56 |
| patrickeast | since its sitting there connected to the initiator anyway | 23:56 |
| asselin | but it doesn't use that much....we run 6 on 300GB | 23:57 |
| asselin | patrickeast, it's not a nodepool issue...it's openstack provider. | 23:57 |
| patrickeast | hmm? i think its just a matter of adding in the flow to create volumes from images and booting from them instaed of direct boot from image | 23:58 |
| asselin | patrickeast, i.e. you can configure nova & glance to use your storage array for images & instances | 23:58 |
| patrickeast | or maybe there is a shorter step i don’t know about | 23:58 |
| asselin | patrickeast, ok i see | 23:58 |
| patrickeast | it would be cool too to have snapshots instead of images, going snapshot to new volume is almost a no-op for us | 23:59 |
| rhe00 | patrickeast, asselin: thanks for the help so far! I'll keep working on it. | 23:59 |
| patrickeast | rhe00: np | 23:59 |
