| alex_xu | efried: hey, i'm here | 12:10 |
| efried | alex_xu Hi. I'm glad you figured out that bug in my test. | 12:11 |
| efried | At some point I'd like to get some tips on how you debug this stuff. | 12:11 |
| alex_xu | efried: I drop in the same trap before, that is really hard thing to remember | 12:11 |
| efried | Ah, okay. | 12:11 |
| *** markvoelker has quit IRC | 12:11 | |
| efried | Well, I'll know for the future. | 12:11 |
| efried | I was of course thinking my "add allocation" was actually going to *add* an allocation. | 12:12 |
| efried | Like, why couldn't you have two separate allocations rows for the same RP/RC | 12:12 |
| efried | But I guess if you're e.g. resizing, you're supposed to do the math on the client side and replace the whole record. | 12:13 |
| efried | Anyway - how would you like to split up that one test case? Where the three inventories all have something that excludes them from the result. | 12:13 |
| alex_xu | efried: yea, something like that as i remember | 12:13 |
| alex_xu | efried: I like your current way | 12:14 |
| efried | Talking about this: https://review.openstack.org/#/c/514197/4/nova/tests/functional/db/test_resource_provider.py@2387 | 12:14 |
| alex_xu | ah | 12:15 |
| efried | You want to create separate RPs for each different way an inventory can be exclude-worthy? | 12:15 |
| *** jaypipes has joined #openstack-nova | 12:15 | |
| efried | Morning jaypipes ! | 12:16 |
| efried | (sorry, too cheerful?) | 12:16 |
| alex_xu | efried: we can create three RPs , one hasn;t enough total vcpu, one hasn't current max_unit, the last one reserved a lot | 12:17 |
| efried | alex_xu And is the idea for those RPs to be included or excluded? | 12:17 |
| *** kylek3h_ has quit IRC | 12:17 | |
| *** moshele has quit IRC | 12:17 | |
| alex_xu | efried: all of us are cheerful when seeing jaypipes online :) | 12:17 |
| efried | alex_xu i.e. do we want to create any other inventory in those RPs that makes them show up in the resulting candidate list? | 12:17 |
| alex_xu | efried: exclude | 12:17 |
| efried | Okay. | 12:17 |
| alex_xu | efried: we should create inventory which match the request for other resource | 12:18 |
| *** slaweq has quit IRC | 12:18 | |
| efried | Sorry, I didn't follow that one. | 12:18 |
| alex_xu | efried: the reason is due to this https://review.openstack.org/#/c/514197/4/nova/objects/resource_provider.py@846 | 12:18 |
| alex_xu | efried: your first VCPU inventory https://review.openstack.org/#/c/514197/4/nova/tests/functional/db/test_resource_provider.py@2381 doesn't have enough vcpus | 12:19 |
| *** phuongnh has quit IRC | 12:19 | |

| *** yangyapeng has joined #openstack-nova | 12:20 | |
| efried | alex_xu But just for that one resource. | 12:20 |
| alex_xu | that means the mem and disk invetories acutally weren't tested | 12:20 |
| *** thorst__ has joined #openstack-nova | 12:20 | |
| efried | Oh, I don't think that's true. I hope not, anyway. | 12:20 |
| efried | I have a different RP later on that tests that case... | 12:21 |
| efried | or I thought I did... | 12:21 |
| *** jamesden_ has joined #openstack-nova | 12:21 | |
| alex_xu | But the comment message said three inventory for three different failure case | 12:21 |
| efried | alex_xu The one at L2389 | 12:22 |
| efried | That one has one inventory that's good, one that's bad. | 12:22 |
| efried | In that case, the 'bad' one is because the inventory is exhausted by allocations. | 12:22 |
| efried | But that shouldn't matter, should it? | 12:22 |

| *** jamesdenton has quit IRC | 12:24 | |
| efried | alex_xu In any case, I can expand out all the conditions we're checking for in the SQL. | 12:24 |
| efried | alex_xu But I still don't quite understand which way you're wanting to test. | 12:24 |
| *** thorst_ has quit IRC | 12:24 | |
| efried | alex_xu For each case, do you want (one inventory bad, one inventory good <= this RP should be *included*) or do you want (one inventory bad, no other inventory <= this RP should be *excluded*) | 12:25 |
| alex_xu | efried: based on what you want to test | 12:26 |
| efried | alex_xu Well, I'm not sure what your concern is. | 12:26 |
| alex_xu | efried: the comment https://review.openstack.org/#/c/514197/4/nova/tests/functional/db/test_resource_provider.py@2387 is only about line 2383 and 2386 aren't tested actually | 12:27 |
| efried | alex_xu Are you concerned that one bad inventory will cause the whole thing to be excluded when it really shouldn't be? | 12:27 |
| *** slaweq has joined #openstack-nova | 12:27 | |
| *** ociuhandu has joined #openstack-nova | 12:28 | |
| efried | alex_xu Oh, I think they must be. | 12:28 |
| efried | alex_xu If you were to "fix" either one of those so they're viable, that RP would show up in the result. | 12:28 |
| efried | They have to *all* fail in order to exclude this RP. | 12:28 |
| efried | Don't they? | 12:28 |
| jaypipes | efried, alex_xu: did you see my suggestion on renaming that "root providers" to "non-sharing providers"? | 12:29 |
| *** markvoelker has joined #openstack-nova | 12:29 | |
| *** jsheeren has joined #openstack-nova | 12:29 | |
| alex_xu | efried: no, they are exclue, one RP hasn't enough VCPU, but has enough disk and mem, will be exclude | 12:29 |
| efried | jaypipes I saw you "abstained" from my leetle survey, but I hadn't yet seen that, no. | 12:29 |
| jaypipes | efried: I didn't abstain. I voted no on all options :) | 12:30 |
| efried | jaypipes Cool. So you're in favor of "non-sharing"? | 12:30 |
| jaypipes | efried: you fancy taking over the resource providers summary email for cdent the next 3 weeks? | 12:30 |
| alex_xu | jaypipes: sorry, I didn't see that, where is it? | 12:31 |
| jaypipes | efried: I am in favor of "non-sharing providers", yes | 12:31 |
| jaypipes | alex_xu: in the commit message comment.. | 12:31 |
| * jaypipes checks that he actually saved the darn gerrit comment.... | 12:31 | |
| alex_xu | which patch....? | 12:31 |
| jaypipes | alex_xu: https://review.openstack.org/#/c/480379/ | 12:32 |
| efried | jaypipes Oh, uh, I could try to do that. I don't really have a handle on some of the sub-sub-pieces. | 12:32 |
| *** Eran_Kuris has quit IRC | 12:32 | |

| jaypipes | efried: we can split the work between the two of us if you'd prefer. | 12:33 |
| jaypipes | efried: are you going to Sydney? | 12:33 |
| alex_xu | jaypipes: yea, non-shared provider sounds the right way | 12:33 |
| efried | jaypipes Fraid not. | 12:33 |
| *** catintheroof has joined #openstack-nova | 12:33 | |

| jaypipes | geez, I am turning into my dad. | 12:34 |
| efried | That's way better than I got in grade school. | 12:34 |
| alex_xu | jaypipes: initial I thought that should be RP for compute node, the compute node always the root of nested resource provider, but yes, the child resource provider also can share something with others, so non-shared resource provider sounds right | 12:34 |
| jaypipes | efried: I'm not going to Sydney either, so we can tackle the summary email between the two of us. | 12:34 |
| efried | jaypipes Okay, sounds good to me. | 12:34 |
| jaypipes | alex_xu: makes sense for compute nodes, yes, but eventually we'd like to detach the placement service from being compute-specific. | 12:35 |
| alex_xu | jaypipes: yea | 12:35 |

| jaypipes | jsheeren: what's up? | 12:37 |
| jsheeren | i'm running into an issue with instance resize of instances with a cinder backed root disk | 12:37 |
| jsheeren | the resize does a resize_cleanup action, which checks if a root disk exists | 12:37 |

| efried | jaypipes Point of design for GET /allocation_candidates. Let's say I request inventory in three RCs. There's a RP with inventory in two of those RCs. But one of them is exhausted or otherwise unsuitable (wrong step_size, whatever). Should I *still* get a candidate with that RP in it (assuming another RP in the tree/aggregate can satisfy the other two pieces of the resource request)? | 13:08 |

| cdent | efried: on your inventory question above, if I’m understanding the question correctly (I’m not sure I am) the answer is “yes”. Why, in the dances of your mind, would it be "no"? | 13:24 |
| efried | cdent I agree. alex_xu and I have been debating it. | 13:25 |
| *** vladikr has quit IRC | 13:25 | |
| efried | cdent He raised a valid point, which was, "Give me a real world example where this could happen." | 13:25 |
| *** lbragstad has quit IRC | 13:25 | |
| cdent | always a useful point | 13:25 |
| *** hshiina has quit IRC | 13:26 | |
| efried | cdent It took a while, and eventually I had to resort back to the "DISK_GB provided by both local storage and a shared RP" thing. | 13:26 |
| cdent | “real world example” depends on the answer to “can a compute node have local and shared disk” if the answer is yes, we get all sorts of examples, yeah? | 13:26 |
| cdent | jinx! | 13:26 |
| efried | hah! | 13:26 |

| openstackgerrit | Matthew Booth proposed openstack/nova master: Automatically revert resize which fails on destination https://review.openstack.org/462521 | 13:26 |
| alex_xu | yea, finally, efried beats me | 13:27 |
| cdent | efried: I think the api should allow for that possibility, even if compute nodes don’t or won't | 13:28 |
| cdent | as we can’t see the future of placement | 13:28 |
| *** superdan is now known as dansmith | 13:28 | |
| cdent | and limiting placement for the models presented by today’s compute nodes is limiting | 13:28 |
| efried | cdent The first example I came up with was: You're on a compute that's NUMA-capable and modeled with its CPU and memory resources in NUMA nodes, but you're making a request that doesn't care about NUMA affinity, so you should be able to get your VCPU from one NUMA node and your MEMORY_MB from a different one. | 13:28 |
| cdent | I still find that modeling hard to stomach, but yeah, if you’re doing it that way, I agree | 13:29 |
| *** salv-orlando has joined #openstack-nova | 13:30 | |

| efried | alex_xu So what's the path forward from here? Looks like we need to rework the logic some more. | 13:32 |

| *** lbragstad has joined #openstack-nova | 13:33 | |
| efried | alex_xu But with the new test case? | 13:33 |
| jaypipes | efried: if there's no constraints saying that all three RCs need to be provided by the same RP, then sure. | 13:34 |
| efried | jaypipes ++ | 13:34 |
| alex_xu | efried: yea | 13:34 |
| efried | alex_xu Okay. I'll bring back PS2, expand the test case to include some more permutations of RPs, and we'll see if it passes. | 13:35 |
| efried | alex_xu If it doesn't, you get to fix the SQL :) | 13:35 |

| efried | jaypipes I'm about to be afk for a couple of hours, but: We do need to distinguish between unnumbered and numbered, remember, because the unnumbered can come from any RP in the tree or aggregate; whereas numbered has to come from exactly the same RP. | 16:40 |

| jaypipes | efried: sure | 19:13 |
| efried | jaypipes So first of all I'd like to set the baseline that what I've got proposed thus far is what's described in the spec. | 19:14 |
| efried | jaypipes Then we can go into whether the spec is wrong, and what to do about that. | 19:14 |
| efried | jaypipes I was just going over the comments on the spec myself... | 19:14 |
| efried | https://review.openstack.org/#/c/510244/ | 19:14 |
| efried | jaypipes Unfortunately I realize that this spec was basically written, reviewed, and approved while you were out. (I do remember you acking it when you got back, but I recognize that's not the same thing as being involved in the review process.) | 19:16 |
| *** yamamoto has quit IRC | 19:16 | |
| *** READ10 has quit IRC | 19:17 | |
| jaypipes | efried: the only difference I see between the resources= key that exists now and the resourcesN= keys that are in that spec is that the resources= key can have part of its request satisfied by a sharing provider. | 19:19 |
| efried | jaypipes In which case we nevertheless need to keep them semantically separate when processing them, nah? | 19:21 |
| efried | jaypipes I mean, I think we still wanted to get narrower than that, but that at the very least should be enough motivation to have a distinction. | 19:21 |
| jaypipes | efried: sure, but I'd prefer we just annotate the RequestGroup with a "can_use_shared_resources" attribute or similar | 19:22 |
| efried | jaypipes Oh, rather than calling it 'numbered' vs 'unnumbered', sure I'm open to better ways of describing. | 19:22 |
| jaypipes | right | 19:22 |
| efried | jaypipes But IIUC, we can't share an object between the scheduler side and the placement side, can we? | 19:22 |
| jaypipes | cuz numbered and unnumbered doesn't indicate what the diff is. | 19:23 |
| jaypipes | that was my complaint. | 19:23 |
| jaypipes | efried: no, we can't share an object, but that's not the point. The point is to have an attribute that indicates what the difference between the things is. "numbered" and "unnumbered" doesn't do that. | 19:23 |
| jaypipes | that's what I was trying to say | 19:24 |
| efried | jaypipes Cool, I'm good with that for sure. | 19:24 |
| efried | jaypipes Back to the other issue... | 19:24 |
| jaypipes | efried: the over-the-HTTP-wire syntax of using numbers is fine. I'm just saying when creating objects that represent these things, let's not call them "unnumbered" or "numbered" | 19:24 |
| efried | jaypipes Dig | 19:25 |
| jaypipes | k, cool. | 19:25 |
| openstackgerrit | Andreas Jaeger proposed openstack/nova master: DNM - testing check-requirements https://review.openstack.org/516195 | 19:25 |
| efried | jaypipes So the "non-sharing" group can get resources from any RP in the tree or any RP in the same aggregate. We're agreed on that. | 19:25 |
| efried | jaypipes Bah, I meant the "sharing" group. | 19:25 |
| efried | Cause this wasn't confusing enough. | 19:25 |
| efried | jaypipes Per the spec, the "non-sharing" group is limited to getting its resources from exactly one RP. No trees, sub-branches, etc. | 19:26 |
| jaypipes | efried: ok, if that's what was agreed to in the spec, cool. | 19:27 |
| efried | jaypipes Okay, good deal. I think the thing about using branches *might* work, but only because we can't think of a case right now where a parent and child would both provide inventory in the same RC. | 19:27 |
| efried | Cleaner to keep it same-RP. | 19:27 |
| jaypipes | right | 19:28 |
| jaypipes | efried: how about RequestGroup.use_same_provider as the attribute name and make the parser set that to True for any request group with a number in the query param. | 19:29 |
| efried | jaypipes Dig. | 19:29 |
| jaypipes | coolio. | 19:29 |
| efried | jaypipes So do you want me to have a (separately-defined) RequestGroup class on the placement side of the world as well? | 19:29 |
| efried | Not a DB object, obviously; just a util/helper. | 19:30 |
| mriedem | sdague: want to send this through? https://review.openstack.org/#/c/508271/ | 19:33 |

| mriedem | clarkb: ok. i just figure anyone that is a user of openstack and has to rely on scheduler hints for their app to work, probably has a hell of a time making that app work across different clouds - but i have no idea if something like that exists in the wild | 20:20 |
| clarkb | I know ovh schedules us to dedicate resources so we don't noisy neighbor their customers | 20:21 |

| mriedem | ok, so what's probably happening is conductor is trying to 'claim' allocations in placement at the same time as the scheduler for a concurrent test, and capacity changed so we have to retry client-side, just like in the scheduler | 21:22 |

| *** kfarr has quit IRC | 21:39 | |

| mriedem | kukacz: check this out https://docs.openstack.org/nova/latest/user/vendordata.html | 21:43 |
| mriedem | configure nova for force_config_drive=True so every instance gets a config drive, and then you can setup a vendordata v2 service for injecting whatever you need into the guest | 21:43 |
| mriedem | jaypipes: for this todo, we'd want a microversion so the client can detect if it can rely on the server doing the retries or if the client has to do them https://github.com/openstack/nova/blob/965f56d7d2ca1f668f70d24d4dcc20e418bb5b9c/nova/objects/resource_provider.py#L1887 | 21:46 |
| mriedem | jaypipes: but i'm wondering if we want to make that a hard-coded retry value in placement (or configurable), or allow the user to pass in the number of retries (probably not) | 21:46 |
| openstackgerrit | OpenStack Proposal Bot proposed openstack/os-vif master: Updated from global requirements https://review.openstack.org/511035 | 21:47 |
| mriedem | or allow the user to request a certain number of retries but have a configurable max in placement, defaulted to 3? | 21:47 |
| kukacz | mriedem: thanks! looking into that | 21:47 |
| *** Sukhdev has joined #openstack-nova | 21:48 | |
| dansmith | mriedem: is that a generation mismatch thing? | 21:48 |
| mriedem | dansmith: yup | 21:48 |
| cfriesen | mriedem: does a rebuild in the boot-from-vol case rebuild any of the volume connection stuff in a way that wouldn't happen on a stop/start? if so then maybe we'd only want to fail if we try to rebuild to a different image | 21:48 |
| dansmith | mriedem: so we're not retrying those in the reportclient I guess? | 21:48 |
| mriedem | dansmith: not in put_allocations | 21:48 |
| mriedem | which is what the migrate task uses | 21:48 |
| dansmith | ack okay | 21:49 |
| mriedem | the claim_resources method in the reportclient is the thing the scheduler calls and that does the double up and retry logic | 21:49 |
| dansmith | okay | 21:49 |
| dansmith | mriedem: you gots a bug yet? | 21:49 |
| mriedem | so we could hacky sack a bit and have migrate call claim_resources but pass a "don't double things" | 21:49 |
| mriedem | dansmith: yeah https://bugs.launchpad.net/nova/+bug/1728722 | 21:49 |
| openstack | Launchpad bug 1728722 in OpenStack Compute (nova) "Resize test fails in conductor during migration/instance allocation swap: "Unable to replace resource claim on source host"" [High,Triaged] | 21:49 |
| dansmith | mriedem: nah, we can just make a wrapper for put that does it I think and refactor a bit | 21:50 |
| mriedem | that's what i started doing, | 21:50 |
| dansmith | mriedem: I'll work on that tomorrow | 21:50 |
| mriedem | but then you end up copying most of the put_allocations method from placement, and have to get the response back for the status_code | 21:50 |
| kukacz | mriedem: which release was this vendordata feature introduced in? Pike? | 21:50 |
| mriedem | and reportclient.put doesn't have the safe_connect on it | 21:50 |
| mriedem | but i think we said we could remove that... | 21:50 |
| dansmith | mriedem: I think we want the wrapper in reportclient though | 21:51 |
| mriedem | kukacz: newton i think, and enhanced in ocata | 21:51 |
| mriedem | dansmith: ah yeah that would work | 21:51 |
| dansmith | mriedem: I would think we could make claim_resources use the wrapped version too | 21:51 |
| dansmith | to avoid that duplication | 21:51 |
| dansmith | anything calling put_allocations shouldn't have to worry about generation retries | 21:51 |
