| jgriffith | My brain has turned a bit mushy after waking through all the bdm stuff all day over and over | 04:02 |
| jgriffith | One thing I left out... I have a system I reproduced this on that the /dev/sdd device is in fact there and the connection is still valid, but that periodic query against it still fails... I didn't go down that rabbit hole yet though | 04:03 |

| dansmith | got that one but still no merge commits | 04:13 |
| mriedem | don't we just need 23c4eb34380bdf3eece11abbe0f6ccb68c060f47 ? | 04:13 |
| dansmith | you list the merge commit in the release thing right? | 04:14 |
| dansmith | not the actual commit | 04:14 |
| mriedem | no, | 04:14 |
| mriedem | tip of master | 04:14 |
| dansmith | your WIP patch is a merge commit | 04:14 |
| mriedem | that was just tip of master at the time | 04:14 |
| dansmith | erm, okay | 04:14 |
| dansmith | so maybe zuul does a ff merge if it's clean or something? I thought it always did merge commits | 04:14 |
| mriedem | you want to update the release patch since you've watched this all night? | 04:15 |
| dansmith | just did | 04:15 |

| dansmith | so I didn't wait all night | 04:17 |
| mriedem | ha | 04:17 |
| mriedem | would have to ask dhellmann tomorrow if there is magic behind the scenes | 04:17 |
| mriedem | now that that's done, i suppose no one is around to actually merge and tag the damn thing | 04:18 |
| dansmith | several I checked from ocata just now were merge commits too | 04:18 |
| dansmith | mriedem: dims said he'd get it in the morning if ttx didn't first | 04:18 |

| SteveRUKC | also, hypervisor_stats is showing a negative number for least_free | 09:39 |

| cdent | the thing that will be missing is that there’s nothing currently in place to manage the allocation of disk on the shared resource provider, but that’s in progress with the claim in the scheduler stuff that is being worked on this week | 10:33 |
| *** iceyao has joined #openstack-nova | 10:33 | |
| bhagyashris | cdent: ohk Means instead of creating the "CUSTOM_DISK" resource class and then creating the inventory for that I need to update the inventory against "DISK_GB" resource class right. | 10:36 |
| *** iceyao has quit IRC | 10:37 | |
| cdent | bhagyashris: well basically the general rule is that if you can use a standard resource class (because it maps to the unit of resource a provider is providing) you may as well | 10:37 |

| cdent | bhagyashris: do you have the log of it making the PUT /allocations requests? It might be that the scheduler is claimng one set of allocations, but later (in the periodic update) the resource tracker is changing things. if you’re going to be using the CUSTOM_DISK resource class you need to make sure your flavor doesn’t indicate any requests for disk_gb | 11:07 |
| cdent | I think over the next few days things are likely to be quite unstable with claims, and there will be a few more changes coming | 11:07 |

| bhagyashris | cdent: Thank you for your time :) | 11:16 |
| cdent | yeah, in the case where you have two different provider of DISK_GB it is likely that the non-shared provider will be picked when there are multiple options. | 11:17 |

| *** iceyao has quit IRC | 13:37 | |
| *** iceyao has joined #openstack-nova | 13:37 | |
| mriedem | cdent: well it does two things | 13:37 |
| *** prateek has quit IRC | 13:37 | |
| mriedem | 1. when the RT (source node during a migration) untracks it's instances and attempts to delete allocations, we get the current allocations for the instance for all providers and if the source node rp uuid isn't in the current list of allocations, it noops | 13:38 |
| *** rcernin has quit IRC | 13:38 | |
| mriedem | 2. if the source node rp uuid is in the list of current allocations but there is also at least one other VCPU resource provider, it logs a message before deleting the allocations | 13:38 |
| mriedem | i have seen #2 in the live migration CI runs, | 13:38 |
| mriedem | i haven't seen #1 | 13:38 |
| mriedem | http://logs.openstack.org/87/488187/2/check/gate-tempest-dsvm-multinode-live-migration-ubuntu-xenial/107a810/logs/subnode-2/screen-n-cpu.txt.gz#_Jul_27_22_21_14_766229 | 13:39 |
| dansmith | yeah so #2 will get reported as a bug and tell us that we need to skip instead of log and continue there | 13:39 |
| mriedem | i really just pushed this to see if things were really bad, like if we hit #1 a lot | 13:39 |
| *** acormier has quit IRC | 13:40 | |
| dansmith | mriedem: you could try setting the heal interval really small so it runs more often during the few migrations we actually do | 13:40 |
| cdent | do you feel better or worse? | 13:40 |
| mriedem | i feel better | 13:41 |
| mriedem | #1 would be a scarier race imo | 13:41 |
| mriedem | and could still happen, but chances are slim - at least in our CI env which isn't that load intensive | 13:41 |
| mriedem | #1 happens after the source node RT pulls the allocations for it's own uuid, | 13:41 |
| mriedem | so to hit #1, that means the allocations are gone for that node between the time it pulls them and the time it processes it's list of untracked instances | 13:42 |
| mriedem | i think #2 is fixed by making the RT check the vm_state of the instance before trying to delete it's allocations | 13:42 |
| mriedem | which is something jay was working on yesterday | 13:42 |
| leakypipes | for the record, guys, I should be done with my patch shortly. | 13:42 |
| bauzas | mriedem: yup, saw the pike-3 change this morning | 13:43 |
| leakypipes | just working on unit tests now | 13:43 |
| bauzas | it was already merged | 13:43 |
| dansmith | mriedem: insert some artificial rpc delay into the periodic and see if #1 happens | 13:43 |
| mriedem | i can do that | 13:43 |

| openstack | Launchpad bug 1707071 in OpenStack Compute (nova) ocata "Compute nodes will fight over allocations during migration" [Medium,Confirmed] | 13:44 |

| leakypipes | dansmith: you need to change your clothes. | 13:45 |
| *** jistr is now known as jistr|mtg | 13:45 | |
| bauzas | what if we should just get the current allocations before deleting them by the scheduler, so in case we know we have a problem, we could put them again ? | 13:45 |
| dansmith | heh | 13:45 |

| *** jjung has quit IRC | 13:47 | |
| bauwser | mriedem: superdan: leakypipes: oh, and me and cdent just discussed about https://review.openstack.org/#/c/427200/ : it could be important for operators | 13:47 |
| *** andreas_s has quit IRC | 13:47 | |
| *** cfriesen_ has joined #openstack-nova | 13:47 | |
| bauwser | superdan: sure, was just wondering if it was simplier than just trying to get two allocations for both source and target when moving | 13:47 |
| bauwser | I know it's the consensus | 13:48 |
| superdan | I don't see how it helps | 13:48 |
| mriedem | bauwser: yes there is an odd scenario in there which i commented on | 13:48 |
| bauwser | and I totally agree with it | 13:48 |
| superdan | without two allocations we're not accounting for the resources used by a moving instance | 13:48 |
| bauwser | but I do wonder if we could simplify the problem | 13:48 |
| bauwser | at least for the races we know of | 13:48 |
| superdan | well, the double allocation. there's still only one allocation for the instance | 13:48 |
| bauwser | the problem here is that we have 3 different services looking at placement when moving : #1 scheduler, #2 source compute, #3 target compute | 13:49 |
| superdan | that's kindof the point of placement right? | 13:49 |
| bauwser | yeah, I know, but that means we have like shared information | 13:49 |
| mriedem | that's the point | 13:49 |
| bauwser | but I think we discussed that yesterday | 13:49 |
| mriedem | the global view | 13:49 |
| superdan | yeah, that's the whole thing | 13:50 |
| bauwser | anyway, I don't want to nitpick | 13:50 |
| mriedem | but yes that means old code that assumes it's all local and owns everything at any given time has to change | 13:50 |
| superdan | it's not the shared state/view/responsibility that concerns me, it's that the current RT was designed for a different model | 13:50 |
| bauwser | I'm just trying to see how to help with the problems we know about multiple services taking the same allocations | 13:50 |
| leakypipes | hopefully my new patch's code comments explain the situation well enough. | 13:51 |
| bauwser | ideally, eventually, I'm not sure we need resouretrackers for computes | 13:51 |
| bauwser | if allocations would only be done by schedulers | 13:52 |
| superdan | bauwser: we don't in the long run | 13:52 |
| superdan | we still need some of that code on the computes, | 13:52 |
| superdan | but not the full RT | 13:52 |
| bauwser | I'd see RTs just *deleting* allocations if something goes mad | 13:52 |
| superdan | that's what I was saying yesterday | 13:52 |
| bauwser | superdan: yeah, I know | 13:52 |
| bauwser | I'm just thinking out loud to try to identify how we could simplify | 13:52 |
| superdan | so.... :) | 13:52 |
| superdan | okay :) | 13:52 |
| bauwser | but I agree with you, using the existing RT means tech deby | 13:53 |

| bauwser | and a shit ton of 3rd-party libs behave the same | 14:19 |

| bauwser | cdent: that reminds me | 14:20 |
| cdent | yes, and? | 14:20 |
| bauwser | cdent: I'm not sure that if we create a trait like CUSTOM_mé | 14:20 |

| mriedem | superdan: looking over my old todo list, i had a note about online data migrations for multiple cells, | 14:55 |
| *** aarefiev is now known as aarefiev_afk | 14:55 | |
| mriedem | e.g. object code looks in the api db first and if not found, looks in the 'cell' db for looking things up | 14:55 |
| mriedem | but with multiple cells, you wouldn't know which cell db to lookup from | 14:55 |
| mriedem | so that probably goes in our list of things you have to do before you can do multi cell | 14:56 |
| superdan | depends on the migration I guess | 14:56 |
| superdan | mriedem: but you could use multiple configs to handle that today | 14:56 |
| superdan | mriedem: i.e. use the config for one of the cell conductors you have if it doesn't hit the api db, and if it does, just add creds for the api db and the one cell you're looking at | 14:57 |
| *** ijw has joined #openstack-nova | 14:57 | |

| *** Drankis has joined #openstack-nova | 14:58 | |
| *** kbaegis has joined #openstack-nova | 14:59 | |
| mriedem | ok i was just thinking about like migrating quotas, we look in api, then look in cell, but really if we did it like the api code, we'd iterate the cells to find the quota limit - although something like quota limits in multiple cells would be wonky - it could be default in a new cell but custom in an old cell | 14:59 |
| mriedem | probably just best to say, make sure your online data migrations are done before attempting adding a new cell | 15:00 |

| mriedem | literally? | 16:27 |
| *** armax has joined #openstack-nova | 16:28 | |

| *** saphi_ has joined #openstack-nova | 16:28 | |

| *** saphi_ has quit IRC | 16:28 | |
| leakypipes | mriedem: yeah. though... in the thing we added for scheduler claiming a double-up allocation, did we account for resize to same host? :( | 16:29 |
| *** gbarros has joined #openstack-nova | 16:29 | |
| mriedem | yes | 16:29 |
| mriedem | it comares the rp uuid right? | 16:29 |
| mriedem | does a set difference | 16:29 |
| mriedem | pretty sure i thought about that when reviewing and came to the conclusion it's handled by the set difference on rp uuid | 16:30 |
| cdent | yeah, but isn’t the point that you still need a doubling and since the rp uuid is the same, you need to double within the allocation, not adjacent to | 16:30 |
| mriedem | no | 16:30 |
| leakypipes | mriedem: yeah, but the issue is that we need to create an allocation for the *same provider* but the resource amounts are added together (old and new amount) | 16:30 |
| mriedem | the double is for the source and target | 16:30 |
| superdan | yes | 16:30 |
| mriedem | so you don't lose the source when putting allocations for the target | 16:30 |
| superdan | but if resize to same host, you still have two copies | 16:30 |
| superdan | so you need twice the allocation | 16:30 |
| openstackgerrit | OpenStack Proposal Bot proposed openstack/nova master: Updated from global requirements https://review.openstack.org/488034 | 16:31 |
| mriedem | i guess you do need to account for the resize up flavor resource class stuff | 16:31 |
| leakypipes | superdan: well, not twice the allocation, but the new amount of resources added to the old amount of resources, but on the same resource provider. :( | 16:31 |
| *** larainema has quit IRC | 16:31 | |
| leakypipes | I hate my life. | 16:31 |
| superdan | leakypipes: yes, I mean the sum of the allocations of course :) | 16:31 |
| mriedem | so is it just that we aren't doing the correct 'new' flavor allocation when resize to same host? | 16:31 |
| superdan | leakypipes: I've been using "doubled up" to mean "the sum" | 16:31 |
| mriedem | is it sum? | 16:31 |
| mriedem | for resize to same host i mean | 16:32 |
| leakypipes | superdan: understood. | 16:32 |
| superdan | it's definitely sum for disk, but I don't think we should distinguish, we should just sum everything | 16:32 |
| mriedem | ok | 16:32 |
| leakypipes | mriedem: yeah, it's sum | 16:32 |
| mriedem | so let's open a bug? | 16:32 |
| mriedem | tag it with pike-rc-potential | 16:32 |
| superdan | if you're resizing to a new flavor with more disk, but fewer cpu/mem, you have to protect the older larger amount of resource | 16:32 |
| mriedem | superdan: good point | 16:32 |
| cdent | leakypipes: on the resourcce tracker side, when the resize confirm wants to delete everything on itself, would it be safe/okay to let that happen, and then immediately call into the _update routines so it would then write a new allocation for the correct size? | 16:33 |
| leakypipes | ffs, we're just going to end up porting all the craziness and conditionals from the resource_tracker.py module into the scheduler report client for this stuff :( | 16:33 |
| leakypipes | cdent: might be, yes... need to think through it. | 16:34 |
| mriedem | cdent: _update only updates inventory | 16:35 |
| mriedem | if you're talking about ResourceTracker._update | 16:35 |
| mriedem | maybe we should rename that :) | 16:35 |
| cdent | I don’t mean _update specifically say _update_* perhaps | 16:35 |
| mriedem | heh | 16:35 |

| *** d9k has quit IRC | 16:35 | |
| mriedem | _update_something_for_instance_maybe | 16:35 |
| cdent | anyway, there’s another wrinkle near this that I wanted to ask about: are those regular allocation update shared providers aware yet? | 16:36 |
| mriedem | don't think so | 16:36 |
| figleaf | cdent: no, but they won't delete the shared provider allocation, right? | 16:36 |

| *** liuyulong has joined #openstack-nova | 16:37 | |
| cdent | figleaf: if we write any allocation at all, it will replace. so it depends on what we’re creating, to write | 16:38 |
| figleaf | leakypipes: sorry, but the nuns beat that stuff into me | 16:38 |
| leakypipes | mriedem: right, and the idea was to not have to call put_allocations() once the placement-claims stuff was done. | 16:38 |
| cdent | I’m thinking in terms of these vaunted “heals” we love. Is a heal going to be correct in the face of a shared provider | 16:38 |
| figleaf | cdent: OIC what you're getting at | 16:38 |
| figleaf | cdent: yeah, that would only work if allocations were consumer/rp specific | 16:39 |
| mriedem | leakypipes: yeah, and my original understanding from 4+ months ago was we'd put code into the computes that wouldn't do anything with allocations if they were already created by the scheduler, and we'd not do claims in the scheduler until all computes had that code | 16:39 |
| mriedem | but then that went away | 16:39 |
| * figleaf gets this feeling that we will end up persisting the allocation_request with the instance | 16:40 | |
| superdan | mriedem: that code _is_ in the computes though | 16:41 |
| superdan | well, part of it | 16:41 |
| mriedem | superdan: the diff thing in the report client you mean right? | 16:41 |
| mriedem | my_allocations vs current_allocations | 16:41 |
| mriedem | ? | 16:41 |
| superdan | yes, but the thing is, | 16:41 |
| mriedem | my_allocations doesn't account for shared storage | 16:41 |
| mriedem | right? | 16:41 |

| openstack | Launchpad bug 1707256 in OpenStack Compute (nova) "Scheduler report client does not account for shared resource providers" [High,Confirmed] - Assigned to Jay Pipes (jaypipes) | 20:06 |
| superdan | leakypipes: um, what? | 20:07 |
| superdan | leakypipes: who un-doubles the move allocation? | 20:07 |
| *** randomhack has joined #openstack-nova | 20:07 | |
| leakypipes | mriedem: by removing the compute node/resource tracker from all allocation operations, we kind of just remove the whole "is this shared or not" problem on the compute node. | 20:07 |
| leakypipes | superdan: that's done in the dependent patch. | 20:07 |
| leakypipes | superdan: https://review.openstack.org/#/c/488510/3 | 20:07 |
| * superdan doesn't get it | 20:08 | |
| leakypipes | superdan: so that's the only place on the compute node that will update allocations. | 20:08 |
| *** catintheroof has quit IRC | 20:08 | |
| superdan | ...okay | 20:08 |
| superdan | leakypipes: so while we're upgrading, | 20:09 |
| superdan | ocata computes will alter/delete the scheduler allocation, and we'll never heal it on pike computes, right? so how do we ensure it heals if it gets damaged? | 20:09 |
| leakypipes | superdan: "mind blown" was referring to my own mind being blown. :) Basically, the patch makes the resource tracker look like what I wanted it to look like once placement-claims was complete. i.e. don't have it mucking with claims/allocations at all. | 20:09 |
| superdan | yeah, I got it | 20:10 |
| superdan | still not sure we can go that far yet | 20:10 |
| superdan | maybe we should hangout to discuss? | 20:11 |
| leakypipes | superdan: still haven't gotten that far in mind yet :) I could go for a hangout walkthrough of ideas. that last patch was more a "let's see what happens" patch than anything else :) | 20:11 |
| openstackgerrit | Hongbin Lu proposed openstack/nova master: Handle exception on adding secgroup https://review.openstack.org/465173 | 20:11 |

| leakypipes | superdan: nah | 20:11 |
| superdan | "let's see what happens in the gate" isn't going to convince me | 20:11 |
| superdan | okay | 20:11 |
| leakypipes | superdan: in any case, I would be good for a hangout. | 20:12 |
| leakypipes | would be useful to talk through some of this. | 20:12 |
| *** randomhack has quit IRC | 20:12 | |
| mgagne | mriedem: ok, I think there is a bug in os-brick. When retrieve the iscsi sessions here: https://github.com/openstack/os-brick/blob/1.15.1/os_brick/initiator/connectors/iscsi.py#L247 | 20:15 |
| mgagne | The returned value should look like so: ['10.0.1.24:3260'] | 20:15 |
| mgagne | Below, it tries to do something I don't fully understand. But iscsi_portals_with_sessions will end up with the value ['.'] | 20:15 |
| mgagne | So I'm not sure how this value is useful for the logic below which compares the bdm target_portal against the above value. In the end, you will always end up with an empty host_devices list. | 20:15 |
| mgagne | That's my hypothesis on what's happening. | 20:15 |
| mgagne | I think it got broken by this refactor despite the comment in the commit "It's worth mentioning that this patch does not touch the extend operation.": https://github.com/openstack/os-brick/commit/56c8665d3d342ce90f5d9433966c0f244063b4c1 | 20:18 |
