| gouthamr | Deadlines... We're two weeks to milestone-1 of the Train release. We have no manila specific deadline at M-1 | 15:05 |

| gouthamr | Please be aware that we have two deadlines that week: | 15:06 |
| gouthamr | - Spec freeze: All Manila specs targeted to Train must be approved by the end of the week. | 15:06 |
| gouthamr | - New driver deadline: By the end of the week all new backend drivers | 15:06 |
| gouthamr | for Manila must be substantially complete, with unit tests, and passing 3rd party CI. | 15:06 |
| gouthamr | ^ reminder, that they don't have to merge by M-2; just code-complete and tested | 15:07 |
| *** lpetrut has quit IRC | 15:08 | |
| gouthamr | That's all I had with respect to deadlines, does anyone else have anything to add? | 15:08 |
| gouthamr | *crickets* :) | 15:09 |

| gouthamr | we have one Inspur driver in the tree, but ^ looks like a new driver for a different storage system in the Inspur family | 15:11 |
| gouthamr | reviewers, please spend some time and take a look at these drivers | 15:11 |
| gouthamr | oh look, there's nothing else on the agenda - so we'll move on to bugs | 15:12 |
| gouthamr | jgrosso: are you around? | 15:13 |
| gouthamr | jgrosso has been working at grooming the bugs, but it's likely he's busy with some downstream activities right now | 15:14 |
| gouthamr | i didn't see any new bugs come in; so let's table the bug discussion for next week | 15:14 |
| jgrosso | no i am here and yes busy | 15:14 |

| geo_ | count me in | 16:05 |
| priteau | Hi geo_ | 16:05 |
| geo_ | still working on the identities; I was turnerg last week | 16:06 |
| priteau | I was going to ask about this | 16:07 |
| geo_ | yeh; old dog, new tricks ya' know | 16:07 |
| priteau | I've put usage enforcement again on the agenda for today, as the conversation was quite lively | 16:09 |
| priteau | #topic Usage enforcement | 16:09 |
| *** openstack changes topic to "Usage enforcement (Meeting topic: blazar)" | 16:09 | |
| priteau | Once question I was asking at the end of the meeting last week | 16:09 |
| priteau | If Blazar was making REST requests to a customisable endpoint on reservation creation / update, expecting to get a simple yes/no answer (with some details, like how much SUs are left compared to how much would be used), would people be motivated to write a small REST service making the link between Blazar and any custom allocation backend? | 16:09 |
| priteau | That's really because each deployment appears to be using some different system for tracking usage against allocations, as there's no standard solution in this space. | 16:11 |
| geo_ | Yeh, you'd have to; speaking for us, it's doable | 16:13 |
| priteau | diurnalist: Would an approach like this be of interest for Chameleon if it meant dropping usage enforcement from your fork? | 16:15 |
| *** gyee has joined #openstack-meeting-alt | 16:16 | |
| *** ttsiouts has quit IRC | 16:16 | |
| diurnalist | priteau: yes, i'm just thinking about what assumptions it introduces in to the data model, as i know there is a lot of discussion about which system's responsibility it really is to manage inventory/reservations | 16:16 |
| diurnalist | but i suppose enforcement is something that makes sense for a system like blazar to encapsulate | 16:16 |
| diurnalist | regardless of how the inventory of resources is managed | 16:17 |
| diurnalist | priteau: how do you imagine tagging resources in blazar with cost models? is this something the custom REST service would also have to deal with? | 16:18 |
| diurnalist | i guess it also depends on how complex of a service you're thinking. a full REST service is actually a bit hard to get right. it would be easier if it was just one endpoint (more RPC), like how the Nova custom vendordata service works. | 16:18 |
| priteau | Yeah I said REST but I was thinking something over HTTP really | 16:19 |
| diurnalist | ah, ok :+1: | 16:19 |
| priteau | That's a very good question about the cost model. If Blazar forwards the list of allocated resources to the HTTP service (or customisable tags associated with them), it could remain completely ignorant of the cost of each resource. | 16:21 |
| priteau | That's more work for the HTTP service of course. | 16:21 |
| priteau | However I can see how teaching Blazar to know a bit about resource cost could be useful to improve resource allocation, e.g. by selecting the cheapest resources. | 16:23 |
| priteau | Let me explain in more details | 16:23 |
| priteau | If you've got a cloud of regular compute nodes and expensive GPU nodes, and users ask to reserve any resource without filtering by node type, Blazar could allocate a GPU node when a regular compute node would have been enough. | 16:24 |
| priteau | We could put a weight tag on each node to help Blazar with selecting the right resource. | 16:25 |
| priteau | But any advanced policy and tracking against externally-stored allocations would have to be done via this HTTP service | 16:28 |
| priteau | That is, unless we go via a Python plugin approach, like vendordata v1 in Nova. But it seems like people are generally moving away from this. | 16:28 |
| diurnalist | Yes, I guess the question is whether cost is important enough to be a concept in Blazar | 16:30 |
| diurnalist | I think that module plugins are indeed going away, and I think that makes sense especially given the popularity of solutions like Kolla, where it becomes a bit harder to inject code like that | 16:31 |
| diurnalist | but this is more of a gut feeling | 16:31 |
| priteau | It wouldn't strictly be related to cost, it could be an abstract weight. Like weighers in Nova scheduler. | 16:32 |
| diurnalist | i'm not 100% on whether blazar should know about cost. rather, the operators could tag resources arbitrarily and pass the resources/tags in to this custom service and deal with them however they want | 16:32 |
| diurnalist | right | 16:32 |
| diurnalist | i wonder if it instead makes sense to just allow this external usage service to return how much usage such and such a reservation will take | 16:32 |
| diurnalist | this could allow flows where users are given feedback on the cost/feasibility of their reservation and make adjustments (as you said, perhaps adding filters to not use GPU nodes?) | 16:33 |
| diurnalist | so, the question being if the blazar resource selection should be smart about some defaults, or whether we just kick the can to the operator's environment | 16:34 |
| priteau | That's simpler and probably better to start with. I get the feeling that if we make this external service take too much responsibility, we will end up just replicating the whole placement <-> nova interaction | 16:34 |
| diurnalist | jay pipes said something in a thread like "don't attempt to deal with quota. there are too many use cases and it will haunt you. forever and ever" or something to that effect ;) | 16:34 |
| diurnalist | yeah | 16:34 |
| diurnalist | priteau: i'm afraid i have to leave the meeting a bit early today. i'll review the notes when i get back! thanks again for organizing. | 16:35 |
| priteau | No problem. Thanks for your valuable input. | 16:35 |
| diurnalist | overall i think this external HTTP service is a good idea, and i'm happy that it will reduce some of our patch burden of course :) | 16:36 |
| priteau | #action Spec an external HTTP service that can compute reservation usage and accept/deny it | 16:36 |

| priteau | #agreed Start with a simple external HTTP service without trying to make smart resource selection | 16:38 |
| priteau | Hi jakecoll | 16:38 |
| jakecoll | Hey, sry I'm late | 16:39 |
| *** diurnalist has quit IRC | 16:40 | |
| priteau | I'll try to start work on this spec, would be nice to get help from jakecoll and diurnalist to cover requirements from Chameleon | 16:42 |
| priteau | Anything else you would like to discuss on this topic? | 16:44 |
| priteau | #topic AOB | 16:46 |
| *** openstack changes topic to "AOB (Meeting topic: blazar)" | 16:46 | |
| priteau | jakecoll: I haven't followed closely how Blazar has evolved in Chameleon in the last couple of months. Do you have new features or bug fixes that would make sense for upstream? | 16:47 |
| *** ttsiouts has joined #openstack-meeting-alt | 16:48 | |
| jakecoll | priteau: I'm working on adding the allocations api to the blazar-dashboard | 16:49 |
| priteau | Nice! Is the API complete enough to implement it? | 16:50 |
| jakecoll | this has involved adding more lease info in the allocations api in stein itself. | 16:50 |
| jakecoll | In stein, there still isn't allocation api support for other resoures like networks for floating ips | 16:51 |
| priteau | No, it's planned for Train | 16:51 |
| jakecoll | Also, would be good to expose extra capabilities via an api call | 16:51 |
| jakecoll | dashboard has to hit db for that info too | 16:51 |
| *** whoami-rajat has joined #openstack-meeting-alt | 16:51 | |
| *** ttsiouts has quit IRC | 16:53 | |
| priteau | Don't you get them if you GET /v1/os-hosts | 16:53 |
| jakecoll | You might be right there | 16:56 |
| priteau | Note that it's a bit slow to run on Chameleon. 10 seconds to get all hosts at UC. Could be more at TACC. If you can figure out why :-) | 16:56 |
| priteau | It may be due to completely unoptimised DB queries | 16:57 |
| priteau | I've checked, they are included in the host description | 16:59 |
| priteau | Extra capabilities just show up as extra keys | 16:59 |
| priteau | We're at the end of the meeting. Thanks for the update jakecoll! | 16:59 |
| priteau | And thanks everyone for joining. Talk to you in two weeks! | 16:59 |
