| BobBall | When we _remove_ a config option (i.e. not just deprecate) will config files that have that old option fail to parse? or will the option be ignored? | 09:38 |
| *** houming has quit IRC | 09:39 | |
| johnthetubaguy | BobBall: I thought you just get a warning log, or something, but I don't 100% remember, although a vaguely remember checking that recently when we removed one | 09:39 |
| johnthetubaguy | BobBall: are you seeing different? | 09:40 |
| BobBall | Not seeing - commenting on https://review.openstack.org/#/c/213112/21/nova/virt/xenapi/driver.py - I had a vague feeling that the config would fail to load if it included unknown options | 09:40 |
| BobBall | and therefore deprecating options that were being ignored still made sense, to give the admin a chance to remove them from config files before nova failed to start | 09:40 |
| BobBall | Actually I can test really simply can't I... | 09:41 |

| *** qeelee has quit IRC | 09:57 | |
| tdurakov | pkoniszewski, why not to pass migration object, as compute will go back to api to get migration by id | 09:57 |
| pkoniszewski | tdurakov: we would need to refresh object anyway to check status, so i'm not sure it really matters whether we send ID or migration object there | 09:58 |
| tdurakov | pkoniszewski, extra hops | 09:58 |
| pkoniszewski | tdurakov: doesnt refresh generate the same? | 09:59 |
| tdurakov | pkoniszewski, which refresh? | 09:59 |
| pkoniszewski | object.refresh() | 09:59 |
| *** e0ne has quit IRC | 10:00 | |
| tdurakov | pkoniszewski, i thought if we pass object no additional queries will be done | 10:00 |
| *** haomaiwang has quit IRC | 10:01 | |
| pkoniszewski | don't we need to refresh the object to get actual state after RPC call? | 10:01 |
| pkoniszewski | so in case RPC took a while we have actual state of migration in manager | 10:01 |

| *** mjura has quit IRC | 10:04 | |
| bauzas | johnthetubaguy: but that said, the job finally failed | 10:04 |
| *** mjura has joined #openstack-nova | 10:04 | |
| pkoniszewski | tdurakov: it can, but by refreshing status and checking it we are reducing chances to the minimum | 10:04 |
| bauzas | johnthetubaguy: so the gate is unlocked now, although with a huge delayu | 10:04 |
| johnthetubaguy | bauzas: OK, well, I guess the gate reset, and we roll the dice again | 10:04 |
| bauzas | yup | 10:05 |
| bauzas | and that's a real problem IMHO | 10:05 |
| pkoniszewski | tdurakov: still need to implement one more check at driver level, we really never want to pause vm in post migration | 10:05 |
| pkoniszewski | tdurakov: i mean, in rollback, post is not a case there | 10:05 |
| bauzas | johnthetubaguy: oh, I got the failure \o/ | 10:05 |
| bauzas | and that was a timeout which unlocked that indeed | 10:05 |
| tdurakov | pkoniszewski, true, here is the point, if we do this check on api side it's imo reduce this chance at the same level | 10:05 |
| johnthetubaguy | pkoniszewski: tdurakov: I don't like passing the id myself, much prefer passing the object, but I ended up not blocking on that because of the refresh that was needed anyways | 10:06 |
| *** Daisy has quit IRC | 10:06 | |

| *** Daisy has joined #openstack-nova | 10:07 | |
| tdurakov | johnthetubaguy, pkoniszewski delay almost the same, as we do rpc to get migration from db | 10:07 |
| pkoniszewski | tdurakov: well, in ha environments it might vary | 10:09 |
| tdurakov | if we do this check as a last step in api before calling compute we end up with same delay on rpc, anyway, it's better to check in driver real state rather db, agree. | 10:09 |
| pkoniszewski | tdurakov: anyway we still need to make sure that there is an active job in libvirt before actually pausing an instance | 10:09 |
| bauzas | johnthetubaguy: see the problem http://logs.openstack.org/81/283781/6/gate/gate-grenade-dsvm-multinode/3c1b54b/logs/grenade.sh.txt.gz#_2016-03-03_09_51_29_865 | 10:09 |

| pkoniszewski | johnthetubaguy: i have a question regarding you comment there https://review.openstack.org/#/c/287363/2/nova/conductor/tasks/live_migrate.py | 10:19 |
| bauzas | johnthetubaguy: okay, my only concern is that https://review.openstack.org/278124 is +W'd but not yet merged | 10:19 |
| bauzas | johnthetubaguy: for the other cells v2 and resource-providers changes, they won't have a +W in time, but that's life | 10:20 |
| pkoniszewski | johnthetubaguy: at this point migrate_data.block_migration is already calculated | 10:20 |
| pkoniszewski | johnthetubaguy: i can me code use, e.g., only migrate_data.block_migration so we will be able to deprecate block_migraiton argument and finally get rid of this if this is what you think about | 10:21 |
| pkoniszewski | johnthetubaguy: and the real problem is compute manager, not drivers | 10:21 |
| eliqiao | johnthetubaguy: pkoniszewski block_migration won't be used when we cast live_migration to compute node | 10:21 |
| bauzas | johnthetubaguy: so my question is, should we wait for 278124 for providing the mitaka-3 tag or are we confident enough to do the tag today and include the change in the RC | 10:22 |
| pkoniszewski | eliqiao: in case of Xen it will be, https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L5309 | 10:22 |
| johnthetubaguy | pkoniszewski: so I think the argument should represent what comes from the API, so None is a valid value there, the code should use migrate_data for its choices, I think. | 10:22 |
| *** sulo_ is now known as sulo | 10:22 | |
| johnthetubaguy | bauzas: I am really looking at what gets thrown under the bus as soon as we cut the tag | 10:23 |
| johnthetubaguy | bauzas: stuff with a +W on it now can go into the next tarball, and thats OK | 10:23 |
| bauzas | johnthetubaguy: I can tell you for the cellsv2 and resource-providers series | 10:23 |
| johnthetubaguy | bauzas: the cells stuff looks like a few nits away from being merged, but it doesn't deliver enough thats worth waiting for, I fear | 10:26 |
| bauzas | johnthetubaguy: so the nova-manage command requires a respin, and the BuildRequest object patch using it in the compute API isn't yet approved with some concerns | 10:27 |
| johnthetubaguy | bauzas: right, they are mostly nits though, need to go check the nova-manage | 10:27 |

| johnthetubaguy | assuming we didn't break it for some other reason (its untested in grenade right now) | 10:44 |
| johnthetubaguy | we must keep live-migrate working, as its something people do to actually peform their upgrade | 10:44 |

| paul-carlton2 | It relates to host and node handling, but I'm not familiar with the concept of a host having nodes, seen it in the code but never paid much attention | 11:19 |

| bauzas | paul-carlton2: well, the force_hosts concept is indeed making sure that you force on a non-disabled host, that's not a pure "force" | 11:25 |
| *** shaohe_robot1 has joined #openstack-nova | 11:25 | |
| johnthetubaguy | paul-carlton2: basically think ironic and vmware, were a compute node reports many nodes for the one host | 11:25 |

| bauzas | paul-carlton2: that said, the scheduler only filters disabled hosts by the ComputeFilter | 11:28 |
| bauzas | paul-carlton2: if you're using the AZ hack that makes force_hosts, it should give you the right hosts even if disabled | 11:29 |
| *** sahid has joined #openstack-nova | 11:30 | |

| bauzas | sdague: so the gate was blocked on a single job | 13:58 |
| *** unicell has joined #openstack-nova | 13:58 | |
| bauzas | sdague: which is gate-grenade-dsvm-multinode | 13:58 |
| bauzas | for a specific change | 13:58 |
| sdague | bauzas: currently? | 13:58 |
| bauzas | no, earlier todaty | 13:58 |
| sdague | ok | 13:58 |
| *** busterswt has joined #openstack-nova | 13:58 | |
| *** rlrossit has joined #openstack-nova | 13:58 | |
| bauzas | so, the job was running for like 2.5h without doing anything | 13:58 |
| sdague | ok | 13:58 |
| bauzas | after some findings, it was due to a periodic retry in the cinder plugin | 13:59 |
| bauzas | so the general devstack timeout killed it | 13:59 |
| bauzas | sdague: http://logs.openstack.org/81/283781/6/gate/gate-grenade-dsvm-multinode/3c1b54b/logs/grenade.sh.txt.gz#_2016-03-03_09_51_29_865 | 13:59 |
| sdague | ok, is this summarized somewhere in detail? Like a bug or mailing list post? | 13:59 |
| bauzas | not yet | 13:59 |
| bauzas | I was waiting you to be awaken to discuss on that :-) | 14:00 |
| bauzas | as the timeout unblocked the gate | 14:00 |
| sdague | right, it's why we have a hard backstop | 14:00 |
| smcginnis | bauzas: Do you know what driver was being used? | 14:00 |
| bauzas | but I guess it's probably related to the delay we already observed yesterday | 14:00 |
| bauzas | smcginnis: not really but all the stuff is in http://logs.openstack.org/81/283781/6/gate/gate-grenade-dsvm-multinode/3c1b54b/logs/grenade.sh.txt.gz#_2016-03-03_09_51_29_865 | 14:01 |
| bauzas | well, I mean in the logs I mean | 14:01 |
| smcginnis | bauzas: Found it. LVM. That's odd. | 14:01 |
| bauzas | lemme check localrc | 14:01 |
| sdague | bauzas: this looks like a new provider | 14:01 |
| sdague | vexxhost | 14:01 |
| sdague | so are we sure that multinode jobs ever work on vexxhost? | 14:01 |
| *** busterswt has quit IRC | 14:01 | |
| bauzas | let's move that convo in -qa | 14:02 |
| bauzas | jpittier had already an eye on it | 14:02 |
| markus_z | sdague: AJeager in #openstack-doc told me that the draft config-reference docs got updated in Nov 2015 when they switched to rst. The next update will happen shortly before the release. | 14:02 |
| *** busterswt has joined #openstack-nova | 14:03 | |
| sdague | markus_z: can we get that more often | 14:03 |
| sdague | it's really useful to see | 14:03 |
| sdague | and audit in that format | 14:03 |
| *** jed56 has quit IRC | 14:03 | |
| dims | markus_z : sdague : seems like a matter of checking out openstack/openstack-doc-tools and running "autohelp-wrapper update nova" from autogenerate_config_docs directory | 14:04 |
| bauzas | I think the config-references one is semi-automated | 14:04 |
| bauzas | so that requires some human intervention | 14:04 |
| markus_z | sdague: I agree. I'll ask on the ML. The openstack-doc-tools are the key but I cannot commit myself to do that. | 14:04 |
| bauzas | at least that's what I saw when I was digging on how they did the November push | 14:04 |
| johnthetubaguy | bauzas: so I think its time to do the tag for mitaka-3, I can't see us getting any further in the next hour or two, I have -2ed the remaining bits now | 14:05 |
| markus_z | dims: right, that gives you the config-reference manual locally. | 14:05 |
| bauzas | johnthetubaguy: I just uploaded a DNM for quick modifications when we are ready | 14:05 |

| bauzas | johnthetubaguy: I was actually waiting https://review.openstack.org/#/c/278125/14 and https://review.openstack.org/#/c/278598/13 to land but we had a job failure | 14:06 |
| *** ctrath has joined #openstack-nova | 14:06 | |
| johnthetubaguy | bauzas: yeah, I just gave them a FFE, since they have +W | 14:07 |
| alaski | bauzas: yeah I was just looking at that. I'm not sure what Jenkins is struggling with "This change depends on a change that failed to merge." but the parent change is going through check just fine | 14:07 |
| johnthetubaguy | I don't think they critically need to get in the tarball, as I read that | 14:07 |
| bauzas | okay, so I can just edit the commit msg and ask ttx to take a look | 14:07 |
| bauzas | alaski: the dependency merge problem is a known issue | 14:08 |
| alaski | okay | 14:08 |
| alaski | what's the best workaround? | 14:08 |
| bauzas | alaski: it's just telling you that it has been reset because anyway your dependent patch failed to merge | 14:08 |
| bauzas | alaski: well, recheck ? :D | 14:08 |
| bauzas | provided your dependent change is able to make it done | 14:08 |
| alaski | your recheck earlier didn't seem to trigger anything | 14:09 |
| bauzas | wait ? seriously? | 14:09 |
| bauzas | lemme see zuul | 14:09 |
| *** unicell has quit IRC | 14:09 | |
| bauzas | alaski: okay, so I guess 278598 was aborted by zuul because the dependent change had problems | 14:10 |
| bauzas | the neutron job failure | 14:10 |
| bauzas | but I asked to recheck https://review.openstack.org/#/c/278125/14 | 14:11 |
| alaski | right. do we need to wait until that succeeds? | 14:11 |
| *** jaypipes has joined #openstack-nova | 14:12 | |
| bauzas | alaski: we can possibly ask to recheck 278598 but given that we're cutting m3 without that, I'd prefer to wait for it being at least verified by Jenkins | 14:12 |
| bauzas | in order to save a bit of CI resources | 14:12 |
| *** mdrabe has joined #openstack-nova | 14:12 | |
| bauzas | alaski: john gave you FFEs anyway so no real rush to try to land both at same time | 14:12 |
| alaski | sure. I'm just trying to understand what to do in this situation to appease jenkins | 14:12 |
| bauzas | they will just be RC | 14:12 |
| *** cdelatte has joined #openstack-nova | 14:13 | |
| alaski | if the answer is wait until the parent patch merges that's fine | 14:13 |
| bauzas | alaski: well, the problem is that a gate failure implies you asking the check pipeline again | 14:13 |
| bauzas | so, that's twice consuming CI resources | 14:13 |
| bauzas | alaski: yeah indeed | 14:13 |
| *** mylu has joined #openstack-nova | 14:14 | |
| bauzas | alaski: at least making sure that the dependent one is passing the check pipeline I feel | 14:14 |
| bauzas | the gate is quite in a good shape now with 1h15 delay | 14:14 |
| *** links has joined #openstack-nova | 14:14 | |
| alaski | okay, so once it gets into the gate pipeline a recheck might work. I'll wait, just wondering for my own edification | 14:14 |
| *** mylu has quit IRC | 14:15 | |
| johnthetubaguy | bauzas: just edited the commit message, I think we are all good otherwise? https://review.openstack.org/#/c/287810/ | 14:15 |

| lucasagomes | johnthetubaguy, hi there, re FF, do you think that the host state level locking feature would be eligible for a feature freeze exception this cycle ( https://review.openstack.org/#/c/262939 ) ? | 14:42 |
| johnthetubaguy | lucasagomes: I don't think it is really. | 14:42 |
| dansmith | jaypipes: yeah, I had a ping from him last night that made it look like he thought it was good. is it still failing? | 14:42 |
| *** akshai has joined #openstack-nova | 14:42 | |
| *** mriedem has left #openstack-nova | 14:42 | |
| lucasagomes | johnthetubaguy, the feature is fixing a annoying race that hits the ironic users a lot, we even introduced a workaround in the ironic driver to help mitigate it | 14:42 |
| johnthetubaguy | lucasagomes: its a very tight time between m-3 and RC this cycle | 14:42 |
| *** mriedem has joined #openstack-nova | 14:43 | |
| lucasagomes | johnthetubaguy, right, there's anything that we can do to help? Reviewing that code? or having 2 cores in nova to sponsor that feature to amke sure it land this cycle? | 14:43 |
| johnthetubaguy | lucasagomes: if you run a single nova-scheduler, and using the caching scheduler, it should avoid the worst of that | 14:43 |
| *** sfinucan has joined #openstack-nova | 14:43 | |
| *** mylu has joined #openstack-nova | 14:43 | |

| *** mgoddard_ has joined #openstack-nova | 14:45 | |
| dansmith | jaypipes: yep... greek to me | 14:45 |
| lucasagomes | johnthetubaguy, ok cool, I will try to see what can be done and may talk to you later | 14:46 |
| lucasagomes | thanks | 14:46 |
| markus_z | dims: for you too http://lists.openstack.org/pipermail/openstack-dev/2016-March/088217.html | 14:46 |
| edleafe- | jaypipes: did you see the fix I made? According to the docs, that should have worked, but obviously did not | 14:46 |
| johnthetubaguy | lucasagomes: if it were lower risk or it was the same cycle length as other times, and if the code was already ready to merge, maybe, it just seems like too many hurdles at this point | 14:46 |
| *** nelsnels_ has joined #openstack-nova | 14:46 | |
| jaypipes | edleafe-: looking into it now... :) | 14:47 |
| dims | markus_z : +1 | 14:47 |
| johnthetubaguy | lucasagomes: I would be surpized that would make a big impact for ironic, if I am honest, it feels more important for PCI/NUMA related things, but maybe I am missing something | 14:47 |
| lucasagomes | johnthetubaguy, yeah I understand... just wanted to kinda reach out to show that we had high hopes this would land this cycle | 14:47 |
| lucasagomes | johnthetubaguy, it's more like Ironic + TripleO | 14:47 |
| edleafe- | jaypipes: I was following the pattern at http://docs.sqlalchemy.org/en/latest/core/compiler.html - search for 'FunctionElement' | 14:48 |
| lucasagomes | johnthetubaguy, cause when they deploy the undercloud the register N machines and try to deploy N machines (same number) | 14:48 |
| *** Jeffrey4l has joined #openstack-nova | 14:48 | |
| *** mgoddard has quit IRC | 14:48 | |
| lucasagomes | johnthetubaguy, this can cause this race to be very apparent | 14:48 |
| jaypipes | zzzeek: you around? could use your PostgreSQL wizard hat. | 14:48 |
| johnthetubaguy | lucasagomes: yes, agreed its racey, I just don't see how the fix you are pointing at helps that race | 14:49 |
| dansmith | johnthetubaguy: yeah, and if it does, it's buried in the refactor, which makes it really hard to review | 14:49 |
| *** nelsnelson has quit IRC | 14:49 | |
| *** ljxiash has joined #openstack-nova | 14:49 | |
| lucasagomes | johnthetubaguy, this may help to understand https://review.openstack.org/#/c/226235/ | 14:50 |
| jaypipes | edleafe-: I have a feeling it's a type conversion thing... | 14:50 |
| edleafe- | jaypipes: what gives you that feeling? | 14:50 |
| edleafe- | the log said it was an ifnull problem | 14:50 |
| *** haomaiwang has quit IRC | 14:50 | |
| *** haomaiwang has joined #openstack-nova | 14:51 | |
| johnthetubaguy | lucasagomes: agreed about the race, I just don't understand how that patch actually helps | 14:51 |
| jaypipes | edleafe-: because of this: "You might need to add explicit type casts." | 14:52 |
| jaypipes | edleafe-: I'm currently looking at this: http://www.postgresql.org/docs/9.4/static/typeconv-func.html | 14:52 |
| jaypipes | but there's no mention of ifnull() | 14:52 |
| lucasagomes | johnthetubaguy, it helps because since we have many nodes being deployed at the same the schedule may return the same node for 2 spawn() workers | 14:52 |
| edleafe- | jaypipes: that's because ifnull doesn't exist in postgres | 14:52 |
| edleafe- | postgres uses coalesce() | 14:52 |
| lucasagomes | johnthetubaguy, and the way we detect it in Ironic is because the first thing we do is to create a bound between the instance in Nova and the node in Ironic by setting the instance_uuid in the node | 14:53 |
| bauzas | lucasagomes: so, see, I'm very concerned by all the changes it introduces so close to a release | 14:53 |
| bauzas | lucasagomes: while it's something we can workaround by increasing the number of retries | 14:53 |
| lucasagomes | johnthetubaguy, so when it tries to set the instance_uuid and the ironic API returns a conflict (409) it means that the node was already taken | 14:53 |
| lucasagomes | even tho the scheduler returned it as it was suppose to be free | 14:53 |
| jaypipes | edleafe-: COALESCE() should function identically... | 14:53 |
| *** pradk has quit IRC | 14:53 | |
| jaypipes | edleafe-: jinx. | 14:53 |
| lucasagomes | bauzas, sure, I'm just trying to show up and say "hey, if we can make it ffe maybe I can try to help landing it" | 14:54 |
| edleafe- | jaypipes: of course. But sqla doesn't alias the two. | 14:54 |
| johnthetubaguy | lucasagomes: agreed about the problem, I just didn't understand how that patch series helps really, I could be missing something in that patch series | 14:54 |
| *** AndChat457281 has quit IRC | 14:54 | |
| bauzas | lucasagomes: if the change was less impacting, maybe, but it does try a verbatim copy with some slight differences that make me very concerned about creating some unexpected regressions if we're not enough verifying | 14:54 |
| lucasagomes | bauzas, I understand the concerns and it's up to the nova project to decide | 14:54 |
| edleafe- | jaypipes: your code used func.ifnull, and that doesn't get aliased to func.coalesce when running postgres | 14:54 |
| lucasagomes | johnthetubaguy, that patch just makes it fail faster | 14:54 |
| lucasagomes | johnthetubaguy, so the retry filter goes and pick another node for the deployment | 14:54 |
| edleafe- | jaypipes: see http://version2beta.com/articles/migrating-from-mysql-to-postresql-using-sqlalchemy/ - search for ifnull | 14:55 |
| lucasagomes | johnthetubaguy, prior to that it kept retrying to set the instance_uuid until it gave up and failed the deployment | 14:55 |
| *** mgoddard_ has quit IRC | 14:55 | |
| *** eharney has joined #openstack-nova | 14:55 | |
| *** mgoddard has joined #openstack-nova | 14:55 | |
| lucasagomes | so with that feature + using only 1 scheduler, that race would be solved and we wouldn't need to workaround it in the nova driver | 14:56 |
| *** zengine has quit IRC | 14:56 | |
| johnthetubaguy | lucasagomes: but the claim happens on the same stale data that the filters act on | 14:57 |
| *** esracelik has quit IRC | 14:57 | |
| bauzas | johnthetubaguy: it just makes the failure happen earlier in the scheduler, and not on the compute | 14:58 |
| bauzas | johnthetubaguy: so, not technically a retry, see | 14:58 |
| johnthetubaguy | bauzas: but the claim is on the same stale data as the filters right? | 14:58 |
| bauzas | but that's not really changing the fact that ironic wants to place as many VMs as there free slots | 14:58 |
| bauzas | johnthetubaguy: sure, but that's not a retry, and that's what ironic folks are concerned | 14:59 |
| bauzas | anyway, you can't have an algorithm that is able to place optimistically N instances on N hosts | 15:00 |
| bauzas | you necessarly need retries | 15:00 |
| johnthetubaguy | bauzas: I guess I don't understand ironic scheduling, the filter should have ruled it out if the claim would fail, I thought? | 15:00 |
| lucasagomes | johnthetubaguy, I probably need to dig more into the change to see how it actually works... I probably just had high hopes that the state locking thingy would fix that race for us | 15:00 |
| lucasagomes | that was my impression by reading the spec at least | 15:00 |
| bauzas | johnthetubaguy: no, because we consume the resources after we filter | 15:00 |
| *** haomaiwang has quit IRC | 15:01 | |
| *** belmoreira has quit IRC | 15:01 | |
| johnthetubaguy | bauzas: but the resources are still in same in memory objects, I thought? | 15:01 |
| *** haomaiwang has joined #openstack-nova | 15:01 | |
| bauzas | johnthetubaguy: having the consume_from_requests() method being synchronized really helped their problem | 15:01 |
| *** liverpooler has quit IRC | 15:02 | |
| johnthetubaguy | bauzas: sure, that will help, but that has merged already | 15:02 |
| bauzas | johnthetubaguy: having the scheduler claims in place just prevents some kind of back-and-forth but yeah, maybe it's unnecessary | 15:02 |
| *** haomaiwang has quit IRC | 15:02 | |
| johnthetubaguy | bauzas: the claims stop us duplicating logic in filters for all the complicated PCI and NUMA resources, I like that, I just don't see how it helps ironic | 15:03 |
| bauzas | johnthetubaguy: the point is that when decrease your resource usage, it won't fail on the scheduler if you're not having enough space | 15:03 |
| bauzas | ie. you can have negative values AFAIR | 15:03 |

| *** ducttape_ has joined #openstack-nova | 15:03 | |
| *** haomaiwang has joined #openstack-nova | 15:03 | |

| *** mrkz has joined #openstack-nova | 15:04 | |
| *** haomaiwang has quit IRC | 15:04 | |
| bauzas | so, 2 instances could end up having the same destination by doubling their resources | 15:04 |
| bauzas | but | 15:04 |
| bauzas | in the ironic case, there can only be a winner | 15:04 |
| *** haomaiwang has joined #openstack-nova | 15:04 | |
| bauzas | where one instance necessarly takes all the compute space | 15:04 |
| *** rcernin has joined #openstack-nova | 15:04 | |
| openstackgerrit | Vasyl Saienko proposed openstack/nova: Allow to update resource per single node. https://review.openstack.org/287485 | 15:04 |
| bauzas | so, while the scheduler could be happy saying "meh, I have -8GB RAM available", it wouldn't fail, and that would be the compute claim which would say "sorry buddy, not enough space" which raises a retry | 15:05 |
| johnthetubaguy | bauzas: but if you have the correct filters, they will fail were you to hit -ve resources, and the claim and filter are happing on the same stale, pre request (if not using caching scheduler) copy of the host state | 15:05 |
| *** amotoki has joined #openstack-nova | 15:06 | |
| bauzas | johnthetubaguy: no, because it's not atomic | 15:07 |
| bauzas | johnthetubaguy: ie. you can have 2 concurrent requests running thru the filters before entering the synchronized portion | 15:07 |
| johnthetubaguy | bauzas: but each request has its own copy of the host state | 15:07 |

| openstackgerrit | Sean Dague proposed openstack/nova: deprecate manager class options https://review.openstack.org/287867 | 15:09 |
| jaypipes | zzzeek: thx though :) | 15:09 |
| sdague | johnthetubaguy: for consideration - https://review.openstack.org/287867 | 15:09 |
| bauzas | johnthetubaguy: so, there are 3 steps | 15:09 |
| bauzas | johnthetubaguy: get_all_host_states, filter, consume_from_request | 15:10 |
| edleafe- | jaypipes: I have the changes that explicitly calculate the expected values in the stats test | 15:10 |
| edleafe- | jaypipes: want to share your fix, and I can merge them both? | 15:10 |
| bauzas | johnthetubaguy: two concurrent requests could issue two calls to get_all_host_state and consequently have the same resource information, right? | 15:10 |
| johnthetubaguy | bauzas: the same copy of that data, yes | 15:11 |
| bauzas | right | 15:11 |
| bauzas | that's not the same memory object, I agree | 15:11 |
| ndipanov | johnthetubaguy, but stuff on compute host is always accurate | 15:11 |
| ndipanov | the problem with ironic's use case is that | 15:11 |
| ndipanov | you usually deploy X instances onto exactly X hosts | 15:12 |
| jaypipes | edleafe-: yup, just running local test | 15:12 |
| ndipanov | which means it's easy to hit 3 retries | 15:12 |
| bauzas | johnthetubaguy: the problem is then that the filters won't deny one of the two requests if they don't know there is a concurrent request, right? | 15:12 |
| ndipanov | bauzas, right | 15:12 |
| ndipanov | and normally that gets corrected with the claim | 15:12 |
| ndipanov | but triple O use case is | 15:12 |
| johnthetubaguy | bauzas: I agree, but the claims wouldn't deny those either, in the scheduler claim | 15:12 |
| ndipanov | johnthetubaguy, they would with the locking | 15:13 |

| openstackgerrit | Jay Pipes proposed openstack/nova: Make compute_node_statistics() use new schema https://review.openstack.org/286931 | 15:13 |
| jaypipes | edleafe-: ^ | 15:13 |
| johnthetubaguy | ndipanov: but the data is separate set of objects for each request, I thought? unless you are using the caching scheduler | 15:13 |
| *** zz_dimtruck is now known as dimtruck | 15:13 | |
| bauzas | johnthetubaguy: sec, lemme read the proposal again | 15:13 |
| ndipanov | johnthetubaguy, nope | 15:13 |
| edleafe- | jaypipes: looking now... | 15:13 |
| bauzas | oh wait, ndipanov is right | 15:14 |
| bauzas | that's the same reference | 15:14 |
| ndipanov | now that's all good when there is plenty of capacity to make sure that 3 retries is usually fine | 15:14 |
| ndipanov | but triple O use case is exactly the opposite | 15:14 |
| ndipanov | there is the exact amount of capacity | 15:14 |
| edleafe- | jaypipes: heh, that was one of my first approaches, but when I saw the docs, I thought that it wouldn't work | 15:15 |
| bauzas | well, technically, that's not a pure Ironic problem, that's also affecting other drivers, that's just the one-off model from ironic makes it visible | 15:15 |
| *** pushkaru has joined #openstack-nova | 15:15 | |
| *** zenoway has quit IRC | 15:15 | |
| bauzas | makes it *more visible | 15:16 |
| ndipanov | bauzas, yeah | 15:16 |
| *** zenoway has joined #openstack-nova | 15:16 | |
| ndipanov | similar thing with pci devices in NFV proof-of-concept scenarios | 15:16 |
| lucasagomes | bauzas, indeed | 15:16 |
| ndipanov | sadly | 15:16 |
| bauzas | but yeah, I need to confirm but if you're running only one oslo.messaging service worker, that does sounds your memory is shared when you have two concurrent greenthreads right? | 15:17 |
| johnthetubaguy | ndipanov: bauzas: so I totally miss read that before, yeah, I see how the claims help now, even without the caching scheduler | 15:17 |
| *** sridharg has quit IRC | 15:17 | |
| johnthetubaguy | hmm, although a different race, the compute node updates, become more of an issue | 15:18 |
| ndipanov | johnthetubaguy, so the only trick with that BP is that we don't hold a global lock during running of all the filters | 15:18 |
| bauzas | so, you can have two requests but since you only have a shared HostManager storing the host_map info, that does impact that | 15:18 |
| ndipanov | but 2 short lived locks | 15:18 |
| bauzas | ndipanov: right, that's what I said to johnthetubaguy, the synchronized section is *after* filtering | 15:19 |
| ndipanov | well before and after | 15:19 |
| bauzas | by adding a check that if you have negative values, it will suck | 15:19 |
| bauzas | for the moment, you can just decrement your usage, and you don't care whether it's silly or not | 15:19 |
| johnthetubaguy | yeah, thats what I was thinking that happens with the caching_scheduer, but yeah, we already share that | 15:19 |
| johnthetubaguy | the problem we have with ironic, is each build, when it hits the compute node, updates the central state, which then wipes out some of the previously cached stuff in the scheduler, and we get other races, I think, but I could be wrong | 15:20 |
| bauzas | that's why I'm fine with that BP, and I feel it could help reducing the number of retries, but I still think it's something workaroundable for that release and that we could land very soon in Newton | 15:20 |
| *** zenoway has quit IRC | 15:20 | |
| mriedem | sdague: on https://review.openstack.org/#/c/287867/ | 15:20 |
| mriedem | what about things like the security group api and network api and identity backend? | 15:21 |
| ndipanov | bauzas, I don't think it's critical for most users, however it's kinda silly we landed half of it (locking) | 15:21 |
| ndipanov | that said - not my patches so can't really speak on turnaround times | 15:21 |
| bauzas | johnthetubaguy: well, fortunately, we write on DB every time we claim in the compute node | 15:22 |
| johnthetubaguy | bauzas: right, thats the bit I am talking about | 15:22 |
| bauzas | johnthetubaguy: so a scheduler request could read that fresh data right after | 15:22 |
| bauzas | johnthetubaguy: then, not sure I see your point | 15:22 |
| ndipanov | bauzas, yes that's correct | 15:22 |
| ndipanov | every claim is a DB write that | 15:22 |
| *** krtaylor has joined #openstack-nova | 15:23 | |
| ndipanov | and holds a global lock | 15:23 |
| ndipanov | so that's consistent | 15:23 |
| *** tbachman has joined #openstack-nova | 15:23 | |
| bauzas | I feel so | 15:23 |
| ndipanov | well | 15:24 |
| ndipanov | to the best of our knowledge :) | 15:24 |
| edleafe- | jaypipes: pep8 bites again | 15:24 |
| ndipanov | there's still some known races around resizes etc | 15:24 |
| edleafe- | jaypipes: fixing | 15:24 |
| bauzas | and that's also why trying to modify those writes to happen in the DB is subject to discussion, eh jaypipes ;) | 15:24 |
| ndipanov | but they are very small windows | 15:24 |
| johnthetubaguy | well, you loose the inflight things, I think | 15:24 |
| bauzas | ndipanov: that's another problem | 15:24 |
| bauzas | ndipanov: some move operations are not claiming resources | 15:24 |
| ndipanov | bauzas, yeah not relevant to this discussion at all | 15:24 |
| ndipanov | bauzas, even the onest that are | 15:24 |
| jaypipes | edleafe-: guh, thx | 15:24 |
| *** efoley has joined #openstack-nova | 15:24 | |
| ndipanov | are not doing it exactly right | 15:24 |
| bauzas | ndipanov: plus we force some operations to bypass the scheduler, which makes the scheduler blind about the resource usage | 15:25 |
| ndipanov | bauzas, that is true | 15:25 |
| ndipanov | and sad | 15:25 |
| *** geekinutah has quit IRC | 15:25 | |
| bauzas | jaypipes: that's probably another concern about trying to have the scheduler ubiquitous about resource usage | 15:25 |
| bauzas | if you see the above point | 15:25 |
| ndipanov | but also the scheduler will refresh if it's internal memory state is stale compared to the computes | 15:26 |
| ndipanov | so now that we have exclusivity between that update of in-memory state | 15:26 |
| ndipanov | and consume update after the filter ran | 15:26 |
| ndipanov | we should be mostly good I think | 15:26 |
| bauzas | yeah, like I said, the semaphore on consume_from_requests is a great benefit | 15:27 |
| ndipanov | it has to be coupled with the semafore on _update_from_compute_node | 15:27 |
| ndipanov | as both of those write to the memory variables | 15:27 |
| edleafe- | bauzas: that bypassing is a problem that should be fixed | 15:27 |
| ndipanov | bauzas, ^ | 15:28 |
| edleafe- | bauzas: not designed around | 15:28 |
| bauzas | edleafe-: it's an operator usecase, you know | 15:28 |
| ndipanov | edleafe-, we are not designing around it at all :D | 15:28 |

| edleafe- | ndipanov: they can operate without first checking with the scheduler, but they should also make their changes visible | 15:30 |
| johnthetubaguy | doffm: think about patching a host and rotating your VMs, and patching the next host, etc. you really want to target a specific host, regardless of and server group host affinity, etc | 15:30 |
| * bauzas shrugs (rather) | 15:30 | |
| ndipanov | edleafe-, well currently they don't until the next RT periodic refresh :( | 15:30 |

| doffm | johnthetubaguy: Total aside, but I looked in to the aggregate_hosts mapping table. No strong opinion on API vs Cell. Performance wise its probably fine in cell. | 15:32 |

| openstack | Launchpad bug 1548980 in OpenStack Compute (nova) "nova list --deleted as admin fails with 404" [High,In progress] - Assigned to Matt Riedemann (mriedem) | 15:43 |
| mriedem | patch is here https://review.openstack.org/#/c/286423/ | 15:43 |
| mriedem | was a regression in the 2.16 microversion | 15:43 |
| sdague | mriedem: I thought we had a specific call out for that instead | 15:44 |
| mriedem | sdague: i'm just going based on the ironic docs pointed out above | 15:44 |
| *** yarkot_ has joined #openstack-nova | 15:44 | |
| lucasagomes | sdague, yeah i think it was discussed in Tokyo | 15:45 |
| sdague | mriedem: oh, I guess it was https://github.com/openstack/nova/blob/c702ab87c30081625358136ca910add60f650f2b/nova/conf/scheduler.py#L247 | 15:45 |
| sdague | there is a constants bit there | 15:45 |
| sdague | so is there another bit that we need to do like that? | 15:46 |
| bauzas | sdague: that's what is indeed concerned by the ironic spec that we discussed in YVR | 15:46 |
| bauzas | lucasagomes: why are you needing a fresh compute manager ? | 15:46 |
| mriedem | sdague: the compute manager | 15:46 |
| mriedem | sdague: see http://docs.openstack.org/developer/ironic/deploy/install-guide.html#configure-compute-to-use-the-bare-metal-service | 15:46 |
| mriedem | compute_manager=ironic.nova.compute.manager.ClusteredComputeManager | 15:46 |
| sdague | mriedem: hmmm... so are we long term satisfied having an out of tree compute manager? | 15:47 |
| lucasagomes | bauzas, IIRC, otherwise nova would mess up tracking the the available resouces in Ironic | 15:47 |
| bauzas | lucasagomes: you want that ironic compute manager because you want some synchronized method around consuming the resource usage ? | 15:48 |
| dansmith | that's the short term hack, right? | 15:48 |
| bauzas | lucasagomes: that's something we fixed in an earlier release | 15:48 |
| sdague | lucasagomes: right, ok, agreed there is currently a need | 15:48 |
| lucasagomes | bauzas, cause, in Ironic every conductor can potentially manage every node in the cluster | 15:48 |
| mriedem | dansmith: the 2014 short term hack | 15:48 |
| dansmith | mriedem: right | 15:48 |
| dansmith | just saying, long term, we do not want that | 15:48 |
| lucasagomes | bauzas, where in nova, the computes manage a part of the cluster | 15:48 |
| dansmith | and there is something in place to address it going forward | 15:48 |
| bauzas | lucasagomes: sec, lemme verify but I think we put some semaphore in Kilo | 15:48 |
| bauzas | lucasagomes: in the RT | 15:48 |
| sdague | dansmith: what's the long term bit to address this? | 15:49 |
| lucasagomes | bauzas, so if you have more than 1 instance of compute loaded with the Ironic driver they will report the usage for the same nodes in the nova model | 15:49 |
| mriedem | dansmith: i'm assuming that's one of the 20 scheduler specs? | 15:49 |
| bauzas | lucasagomes: which is litterally doing what you do in your module | 15:49 |
| *** yarkot_ has quit IRC | 15:49 | |
| mriedem | resource / inventory / allocation schmorgasboard? | 15:49 |
| lucasagomes | sdague, yeah, sorry for that... We are working in Ironic to get the bits in place | 15:49 |
| dansmith | sdague: ironic doing dynamic management of multiple services owning nodes at the time of deployment | 15:49 |
| dansmith | sdague: the "jroll doctrine" | 15:49 |
| sdague | so I think deprecating this is probably still fine | 15:49 |
| mriedem | the jroll tuna roll?! | 15:49 |
| dansmith | yes definitely | 15:49 |
| bauzas | mriedem: sdague: this is what we want http://specs.openstack.org/openstack/nova-specs/specs/mitaka/approved/ironic-multiple-compute-hosts.html | 15:49 |
| sdague | we just don't remove until ironic is sorted | 15:49 |

| bauzas | 2014.2 | 15:52 |
| lucasagomes | bauzas, right, but I think the problem still no? The ironic model does not fit the nova one very well | 15:52 |
| lucasagomes | bauzas, cause computes are "clusterized" | 15:52 |
| bauzas | lucasagomes: oh, because you have N RTs, right? | 15:52 |
| lucasagomes | where in nova model, each compute will just report the usage/available resources of a small part of the whole cluster | 15:53 |
| bauzas | lucasagomes: ah okay, so you want a global lock, I see | 15:53 |
| bauzas | not something in the RT | 15:53 |
| lucasagomes | I think it's more like an architectural problem | 15:53 |
| bauzas | I agree | 15:53 |
| lucasagomes | not sure if we can solve it with locks | 15:53 |
| lucasagomes | e.g 2 computes will report the same available resources | 15:53 |
| bauzas | that's exactly why we agreed on http://specs.openstack.org/openstack/nova-specs/specs/mitaka/approved/ironic-multiple-compute-hosts.html :-) | 15:54 |
| lucasagomes | nova will then think we have twice as much as ironic actually have available | 15:54 |
| lucasagomes | bauzas, yes | 15:54 |

| sdague | mriedem: what were your other concerns? | 16:03 |
| lucasagomes | sdague, so deprecating is ok, but let's make sure we don't remove until we sort it out for ironic | 16:03 |
| sdague | lucasagomes: sure, I'll leave a code comment | 16:03 |
| lucasagomes | or it will impact in scaling out ironic with nova | 16:03 |
| lucasagomes | sdague, ack, thanks much | 16:03 |

| mriedem | sdague: well, network api and security group api and key manager are all pluggable too | 16:04 |
| mriedem | i'm not sure how far you want to take this | 16:04 |

| mriedem | https://github.com/openstack/nova/blob/master/nova/volume/__init__.py#L22 | 16:05 |

| *** haplo37 has joined #openstack-nova | 16:07 | |
| sdague | ok, I'll do another round and look for them | 16:07 |
| mriedem | i can't tell if the image api is pluggable | 16:08 |
| sdague | I don't think so | 16:08 |
| *** jistr is now known as jistr|call | 16:08 | |
| mriedem | the code appears to use glance always but there is the s3 image backend | 16:08 |
| sdague | security_group api is more complicated, right? | 16:08 |
| mriedem | so i think it is pluggable somehow, i actually traced that down a couple of weeks ago | 16:08 |
| sdague | because n-net and neutron | 16:08 |
| mriedem | well, | 16:08 |
| *** mdrabe has quit IRC | 16:08 | |
| mriedem | if n-net, security_group_api is nova.compute.api.SecurityGroupAPI or whatever | 16:08 |
| mriedem | we have 2 sg drivers in tree, one for nova-net and one for neutron | 16:09 |
| sdague | right | 16:09 |
| mriedem | i'd probably just remove that even as an option | 16:09 |
| mriedem | if your network api is neutron, you use the neutron security group driver, and the same for n-net | 16:09 |
| mriedem | it seems silly not to | 16:09 |
| *** thorst is now known as thorst_afk | 16:09 | |

| sdague | I'll look there | 16:10 |
| mriedem | for network api yes, | 16:10 |
| mriedem | BUT | 16:10 |
| bauzas | sdague: I just said in the review that a scheduler manager entrypoint is not something we use atrm | 16:10 |
| mriedem | it checks neutron and nova and then imports from classpath | 16:10 |
| sdague | bauzas: yep | 16:11 |
| sdague | saw that | 16:11 |
| *** jdurgin1 has joined #openstack-nova | 16:11 | |
| sdague | but we still tell people we'll deprecate before remove | 16:11 |

| bauzas | okay, good | 16:11 |
| bauzas | wfm | 16:11 |
| bauzas | just as a fyi | 16:11 |
| mriedem | sdague: quota_driver is another one | 16:11 |
| mriedem | which is pluggable | 16:11 |
| mriedem | that should probably either be DB or None | 16:11 |

| lucasagomes | bauzas, oh right, thanks! Yeha I bet we forgot to add a release note when the patch for microversion merged in nova | 16:16 |
| sdague | sure | 16:16 |
| mriedem | i realize public cloud interop rah rah rah, but there are still a lot of people running small private clouds or building products off openstack | 16:16 |
| sdague | it's also part of the release notes, I'll clean them up to list all the options | 16:16 |
| mriedem | yeah, i think this kind of thing is bigger than just a release note entry though | 16:17 |

| *** Daisy has quit IRC | 16:17 | |

| sdague | but I do get the concern | 16:17 |
| *** Daisy has joined #openstack-nova | 16:17 | |
| mriedem | i think if you're buying an off the shelf product from a vendor, you get any vendorism issues that come with it | 16:17 |
| mriedem | and you can't report bugs for that stuff upstream and expect us to care | 16:18 |

| *** zengine has quit IRC | 16:21 | |
| bauzas | coolness, that's not super urgent, we're just preparing RC1 | 16:21 |
| sdague | mriedem: if you are buying an off the shelf product from a vendor that is OpenStack (tm), then I disagree | 16:21 |
| *** mdrabe has joined #openstack-nova | 16:21 | |
| mriedem | sdague: then openstack should have a different license | 16:21 |
| mriedem | openstack (tm) | 16:21 |
| sdague | remember, this is all python, you can monkey patch this class out if you like | 16:21 |
| mriedem | right, and vendors will just revert this patch | 16:21 |
| *** Daisy has quit IRC | 16:22 | |
| sdague | mriedem: sure, that's fine, if they change the behavior in a way that's not defcore, then they aren't openstack (tm). | 16:22 |
| mriedem | yeah i guess i didn't think about defcore | 16:23 |
| mriedem | i rarely do honestly | 16:23 |
| mriedem | but if interop is a thing you care about as a customer you will want to see the defcore stamp of approval on said vendored product | 16:23 |

| bauzas | mriedem: lucasagomes: so IIUC, I should mention in https://review.openstack.org/#/c/287244/1/releasenotes/notes/ironic_api_version_opt_deprecated-50c9b0486e78fe6e.yaml that now it pins nova to 1.8 or 1.9 ? | 16:30 |
| bauzas | by lucasagomes's comment, it's v1.9 for mitaka, right? | 16:31 |
| bauzas | well, I guess it will depend on the client version | 16:31 |
| lucasagomes | bauzas, the ironic nova driver pins it at 1.8 | 16:31 |
| markus_z | bauzas: OK, just wanted to double-check | 16:31 |
| lucasagomes | bauzas, 1.9 is the default in the python client | 16:31 |
| *** yamahata has joined #openstack-nova | 16:32 | |
| mriedem | lucasagomes: and ironic api v1.8 was added in liberty right? | 16:32 |
| lucasagomes | mriedem, yup | 16:32 |
| mriedem | so nova's ironic driver in mitaka will require an ironic api from at least liberty | 16:32 |
| mriedem | i think that's what i was trying to get across in the release note review | 16:32 |

| cfriesen_ | So normally we don't allow resizing to a smaller disk. What should be the behaviour if we try to resize from "some ephemeral disk" to "no ephemeral disk"? Currently it accepts the resize action and then silently fails with "ResizeError: Resize error: Unable to resize disk down." in the compute logs. | 17:30 |
| cfriesen_ | I suppose an argument could be made that ephemeral disks are supposed to preserve data for the life of the instance, so it makes sense to not allow resizing to an instance with smaller ephemeral disks. | 17:32 |

| tdurakov | PaulMurray, patch? | 17:52 |
| alaski | cfriesen_: xen hit a similar issue https://bugs.launchpad.net/nova/+bug/1488635 | 17:52 |
| openstack | Launchpad bug 1488635 in OpenStack Compute (nova) "xen: resize assumes an ephemeral was migrated if the new flavor has one" [Undecided,Fix released] - Assigned to Andrew Laski (alaski) | 17:52 |
| PaulMurray | tdurakov, the argument that there is a small window between api and compute doesn't really hold in general | 17:52 |
| *** salv-orlando has quit IRC | 17:52 | |
| alaski | cfriesen_: although xen also allows resize down so the considerations are different | 17:52 |
| PaulMurray | tdurakov, when there is a disruption in messaging the api is usually still accessible to the user because its a rest interface | 17:53 |
| PaulMurray | tdurakov, so a user request can get queued up but not deliverd | 17:53 |
| alaski | cfriesen_: but I would argue that any decrease in disk size of root/swap/ephemeral is a resize down | 17:53 |
| PaulMurray | tdurakov, when that happens users tend to start repeating what they did | 17:53 |
| *** baoli has quit IRC | 17:53 | |
| *** jdurgin1 has quit IRC | 17:53 | |
| PaulMurray | tdurakov, so you end up with several requests all queued up | 17:53 |
| *** sc68cal has quit IRC | 17:54 | |
| PaulMurray | tdurakov, if that happens in this case its likely that the instance will have moved to another host so the pause will be | 17:54 |
| PaulMurray | just fail | 17:55 |
| *** e0ne has joined #openstack-nova | 17:55 | |
| *** sfinucan_ has quit IRC | 17:55 | |

| *** danpb has quit IRC | 17:55 | |
| *** ijw has joined #openstack-nova | 17:57 | |
| PaulMurray | tdurakov, I think doing a pause on an instance that is not migrating will actually pause the instance | 17:58 |
| *** ducttape_ has quit IRC | 17:58 | |
| *** rk4n has joined #openstack-nova | 17:58 | |
| PaulMurray | tdurakov, so checking there is a migration that we think is still running will make the window between the check and the action really small | 17:58 |
| PaulMurray | tdurakov, but you are right, if we go through messaging to do the check it doesn't really help | 17:59 |
| rtheis | osc functional tests for creating an aggregate are now failing within the past couple hours...400 error from the nova api. osc is creating an aggregate without specifying an AZ. Is this an expected behavior change? I suspect it may be related to https://github.com/openstack/nova/commit/e5f3d9a5ebbb4a9238e5d5057c8565c9c0fa0fa6 | 18:00 |
| cfriesen_ | alaski: I'm not sure about swap, since it's expected to get wiped on reboot and there's no filesystem involved. Data on the other two is supposed to be preserved. | 18:00 |
| rtheis | I'm bringing up a recent devstack environment now to verify | 18:00 |
| *** haomaiwa_ has quit IRC | 18:01 | |
| tdurakov | PaulMurray, this window is already small, if we got messaging problem check on compute small will also be useless, another thing in this patch - target host is not current instance host, but migration.source_host instead | 18:01 |
| tdurakov | s/small/side | 18:01 |
| *** haomaiwa_ has joined #openstack-nova | 18:01 | |
| tdurakov | so we will not end up with pause instance that is already migrated | 18:01 |
| *** vilobhmm111 has quit IRC | 18:02 | |
| *** salv-orl_ has quit IRC | 18:02 | |
| *** ijw has quit IRC | 18:02 | |
| alaski | cfriesen_: that's fair. my understanding is that resize down is disabled due to the complexity of ensuring it will succeed since a user may have filled the filesystem. swap would be a special case there, but it is a reduction in resources available. *shrug* | 18:02 |
| *** salv-orl_ has joined #openstack-nova | 18:03 | |
| tdurakov | PaulMurray, if this change is ok, I'd make it to abort live-migration too | 18:03 |

| *** baoli has joined #openstack-nova | 18:04 | |

| *** mariusv_ has quit IRC | 18:05 | |
| *** mariusv has quit IRC | 18:05 | |
| PaulMurray | tdurakov, in this case I am not so bothered because pause is not destructive | 18:06 |
| johnthetubaguy | PaulMurray: tdurakov: I think checking the libvirt live-migrate job is still running would help, at least it would make me feel less worried about things | 18:06 |
| *** mariusv has joined #openstack-nova | 18:06 | |
| *** mariusv has quit IRC | 18:06 | |

| * johnthetubaguy has to go sort out food, etc | 18:07 | |
| PaulMurray | johnthetubaguy, better check the food is still in date before and after putting in oven | 18:07 |
| PaulMurray | johnthetubaguy, I'm cautious like that :) | 18:07 |
| *** cdent has quit IRC | 18:08 | |
| tdurakov | PaulMurray, let me explain my thinking on this: check on compute still not guarantee that live-migration is in progress, also db request is go over rpc, so the period remains the same in both cases, whether we check this on compute side or not. johnthetubaguy, will add check in libvirt, this will make things more secure here | 18:09 |

| PaulMurray | tdurakov, that is good. I think danpb said before that if a job is running its not possibly to tell what kind of job it is? | 18:27 |
| PaulMurray | tdurakov, but that does seem to help | 18:28 |
| tdurakov | PaulMurray, yes, this is true, but we check it on nova side in api migration status | 18:28 |
| tdurakov | PaulMurray, I need to make several tests, after that I'll resubmit this patch | 18:29 |
| PaulMurray | tdurakov, I think that's as good as we can do at the moment. it is likely that if a job is not running the migration has failed or the vm has gone | 18:29 |

| tonyb | but I really want that seperate from the gate process | 22:39 |
| mtreinish | tonyb: yeah, that makes sense | 22:39 |
| mtreinish | that's just wasting cycles when we can just do it periodically in a package repo | 22:39 |
| tonyb | it's generic enough that neutron could use it for ovs or dpdk | 22:40 |
| tonyb | mtreinish: and adds several failure vectors that we dont want. | 22:40 |
| mtreinish | yep | 22:40 |
| tonyb | mtreinish: https://github.com/tbreeds/tbreeds-devstack-plugin-additional-pkg-repos is what I have so far | 22:41 |
