| *** Apoorva has quit IRC | 01:44 | |
| Kevin_Zheng | mriedem: yeah, my initial plan was to fail | 01:44 |
| Kevin_Zheng | mriedem: so should we make destination_type checked in schema or in python? | 01:45 |
| mriedem | Kevin_Zheng: i'm not sure, it would be good to understand what cases, if any, that destination_type could be None | 01:46 |
| *** gcb has joined #openstack-nova | 01:47 | |
| Kevin_Zheng | mriedem: Ok, I understand, I will try more cases | 01:48 |
| mriedem | Kevin_Zheng: oh i see your defaults are copied from what novaclient does | 01:48 |
| *** baoli has joined #openstack-nova | 01:48 | |
| mriedem | i didn't know that novaclient did that | 01:48 |
| mriedem | odd | 01:48 |
| mriedem | mdbooth might have ideas on this | 01:50 |
| Kevin_Zheng | mriedem: but at least with source_type=volume and snapshot, with a None destination_type a bdm will be create and nothing in cinder will happen | 01:50 |
| gmann | mriedem: yes, you are right, its v2.1 schema validation made it to stop None | 01:50 |
| gmann | and we have to fix this all the way till mitaka ? | 01:51 |
| Kevin_Zheng | I think thats also what I did, but suggested by Kevin L Mitchell | 01:52 |
| mriedem | Kevin_Zheng: yeah i see you made that change in novaclient | 01:52 |
| mriedem | i don't think nova (or the client) should guess | 01:53 |
| mriedem | gmann: it's been regressed since probably we added that schema | 01:53 |
| mriedem | gmann: so i plan on backporting it as far as possible | 01:53 |
| gmann | yea :( | 01:53 |
| mriedem | i believe we deprecated the v2 api in liberty | 01:54 |
| openstackgerrit | Matt Riedemann proposed openstack/nova master: Allow None for block_device_mapping_v2.boot_index https://review.openstack.org/430497 | 01:54 |
| Kevin_Zheng | I think we have to dig deeper with the destination_type one, because at least for some cases, it will leave a bdm but nothing else | 01:54 |
| mriedem | Kevin_Zheng: with source_type in 'volume' or 'snapshot' then yes i agree we can default destination_type to 'volume' | 01:55 |
| mriedem | since that's the only dest type for those source types | 01:55 |
| mriedem | but source_type in image or blank it's not that simple | 01:55 |
| huanxie | Hi all, could you help review my patch to fix live migration problems with XenServer https://review.openstack.org/#/c/424428/, thanks a lot~ | 01:56 |
| Kevin_Zheng | hmm, but if the user don't provide destination_type, maybe a default one is reasonable | 01:56 |

| mriedem | Kevin_Zheng: that would be a change in the api behavior | 01:57 |
| *** raunak has quit IRC | 01:57 | |
| Kevin_Zheng | I will check what soure=image and blank goes with None | 01:58 |
| mriedem | now if source_type=blank and guest_format is not None, you could maybe assume destination_type=local | 01:58 |

| *** mvensky has quit IRC | 02:00 | |
| mriedem | Kevin_Zheng: probably, at least for the source_type case | 02:02 |
| mriedem | i mean, source_type in ('image', 'blank') | 02:02 |
| Kevin_Zheng | seems the only confusing type is source=image? | 02:02 |
| Kevin_Zheng | I think source=image dest=None won't work | 02:03 |
| Kevin_Zheng | I will check this one | 02:03 |

| gmann | mriedem: we did in mitaka actually, so in mitaka None should work - https://github.com/openstack/nova/tree/stable/mitaka/nova/api/openstack/compute/legacy_v2 | 02:12 |
| gmann | I mean Mitaka have legacy code and so boot_index on /v2 should go with legacy code not via schema | 02:13 |
| mriedem | gmann: but if you're using the v2.1 API in mitaka, this is still a bug yes? | 02:13 |
| mriedem | because https://github.com/openstack/nova/blob/stable/mitaka/nova/api/openstack/compute/schemas/block_device_mapping.py#L59 | 02:14 |
| gmann | mriedem: yea for /v2.1 it is bug from starting | 02:16 |

| sfinucan | i.e. do we really need to use 'CONF.use_ipv6' here https://github.com/openstack/nova/blob/d48aeb5783ea9bd9495eb2e7c67bc587dfd7d85d/nova/virt/netutils.py#L131-L132 | 11:39 |

| mdbooth | So we can take a lock on the compute node, but we're still operating on a list which was generated outside of that lock. | 12:29 |

| mordred | (it needs a little clean up and more docs of course) | 14:06 |
| EmilienM | so I'm deploying Nova from trunk, in eventlet (we removed WSGI/Apache for nova API like you suggested) | 14:06 |
| EmilienM | we start nova services and then run the discover hosts command. Though it seems like the nova scheduler can't find the compute node registered | 14:07 |
| *** slaweq has quit IRC | 14:07 | |
| EmilienM | and it looks like the compute didn't register to placement api: http://logs.openstack.org/71/430571/1/check/gate-tripleo-ci-centos-7-nonha-multinode/bae4746/logs/subnode-2/var/log/nova/nova-compute.txt.gz#_2017-02-08_06_43_28_610 | 14:07 |
| mordred | sdague: so like instead of this: http://git.openstack.org/cgit/openstack/os-client-config/tree/os_client_config/vendors/rackspace.json being in the os-client-config repo, it could just be in the catalog (which, of course, is mildly problematic because auth_url and auth_type still need to be discovered from somewhere, but baby steps) | 14:07 |
| *** mdrabe has quit IRC | 14:08 | |
| EmilienM | you can see nova-conductor which fails to find compute resource: http://logs.openstack.org/71/430571/1/check/gate-tripleo-ci-centos-7-nonha-multinode/bae4746/logs/subnode-2/var/log/nova/nova-conductor.txt.gz#_2017-02-08_06_41_56_037 | 14:08 |

| EmilienM | cdent: the thing it, when we deploy nova from ocata-3, it works fine. Let me show you tripleo logs from our CI where nova trunk is not used | 14:32 |
| johnthetubaguy | are those placement credentials passing the placement is_admin check, for example? | 14:32 |
| EmilienM | cdent: http://logs.openstack.org/47/430447/1/check/gate-tripleo-ci-centos-7-nonha-multinode/dd43509/logs/subnode-2/var/log/nova/nova-placement-api.txt.gz#_2017-02-07_23_06_08_825 | 14:33 |
| johnthetubaguy | EmilienM: thats probably just after we starting asking placement which host to use, potentially | 14:33 |
| EmilienM | cdent: that is a CI job that doesn't run nova from trunk, but nova from ocata-3 | 14:33 |
| EmilienM | johnthetubaguy: what is is_admin check ? | 14:33 |
| cdent | EmilienM: can you enumerate what's different on the tripleo side, besides the switch to using nova-api with eventel (if anything)? | 14:34 |

| cdent | EmilienM: I'm not sure. It would just be useful to be able to figure out what if anything may have impacted what's going on. | 14:40 |
| EmilienM | the major thing is that we switched back to eventlet | 14:40 |
| *** Swami has joined #openstack-nova | 14:41 | |
| dansmith | EmilienM: not for n-cpu which is where this problem is, right? | 14:42 |
| EmilienM | dansmith: I'm afraid I don't understand the question. We switched Nova API to not run in WSGI with apache, but run in classic eventlet. What are you asking about nova compute? | 14:44 |
| *** prateek has quit IRC | 14:44 | |
| dansmith | EmilienM: the problem is that nova-compute is not reporting into placement for the subnode right? | 14:44 |
| johnthetubaguy | FWIW, this error log on the first compute node seems odd to me, not sure if thats normal: http://logs.openstack.org/71/430571/1/check/gate-tripleo-ci-centos-7-nonha-multinode/bae4746/logs/var/log/nova/nova-compute.txt.gz#_2017-02-08_06_43_11_488 | 14:44 |

| mriedem | we should probably drop that down from an error | 14:45 |
| EmilienM | dansmith: the subnode is a single node overcloud, consider it as a all-in-one node | 14:45 |
| cdent | EmilienM: there's no evidence that the placement application has ever been contacted (in the web logs), unless I'm looking at the wrong ones | 14:45 |

| EmilienM | dansmith: node1 == undercloud, which is completely another story (and by the way, undercloud can deploy the overcloud fine in OVB jobs, that run Nova / Ironic) | 14:45 |
| dansmith | the passwords in the two nodes for placement look very different | 14:45 |
| EmilienM | dansmith: yeah don't look at subnode1 please | 14:46 |
| dansmith | alright | 14:46 |
| EmilienM | dansmith: that's another instance of nova, that we don't use in this case | 14:46 |
| EmilienM | subnode2 is the only logs we should look today | 14:46 |

| dansmith | I'm looking at -2 | 14:47 |
| EmilienM | ok good | 14:47 |
| dansmith | or are you calling the primary node "subnode1" ? | 14:47 |
| EmilienM | so: http://logs.openstack.org/71/430571/1/check/gate-tripleo-ci-centos-7-nonha-multinode/bae4746/logs/var/log/nova/ is the undercloud and please don't look at it we don't care now | 14:48 |
| EmilienM | http://logs.openstack.org/71/430571/1/check/gate-tripleo-ci-centos-7-nonha-multinode/bae4746/logs/subnode-2/var/log/nova/ is overcloud, and we currently can't spawn a VM on it | 14:48 |
| johnthetubaguy | according to placement, its only ever been reached by the scheduler I guess | 14:48 |
| EmilienM | FYI I'm using https://review.openstack.org/#/c/430571/ for testing | 14:48 |
| cdent | johnthetubaguy: yes (I was looking at the main logs when I saw no activity above, not the subnode-2, but subnode-2 is just hearing from the scheduler) | 14:49 |
| johnthetubaguy | I just wish we had more details on why compute isn't able to talk to placement in here: http://logs.openstack.org/71/430571/1/check/gate-tripleo-ci-centos-7-nonha-multinode/bae4746/logs/subnode-2/var/log/nova/nova-compute.txt.gz#_2017-02-08_06_43_28_610 | 14:49 |

| dansmith | ot | 14:50 |
| dansmith | it is clearly hitting placement because it's getting Unauthorized right? | 14:50 |
| dansmith | which means that the service catalog is working, and that the credentials just aren't right I think | 14:51 |
| dansmith | unless it's hitting placement for the undercloud somehow, but I doubt it | 14:51 |
| cdent | dansmith: where is unauthorized happening? | 14:51 |
| EmilienM | dansmith: our current CI jobs (pin to nova-ocata-3) use the same credentials, and it seems to work. I can give you a link so you can confirm | 14:51 |
| dansmith | cdent: https://github.com/openstack/nova/blob/master/nova/scheduler/client/report.py#L70-L76 | 14:51 |
| dansmith | cdent: that's the message in the logs, yes? | 14:52 |

| *** jpena|lunch is now known as jpena | 14:52 | |
| johnthetubaguy | EmilienM: would wouldn't notice anything wrong if compute couldn't ever talk to placement until after ocata-3 | 14:52 |
| EmilienM | ok now i'm checking our haproxy config, etc to make sure placement api is reachable | 14:52 |
| dansmith | cdent: placement access log is completely empty on the undercloud? | 14:52 |
| EmilienM | yeah | 14:53 |
| EmilienM | please don't look undercloud for multinode jobs | 14:53 |
| EmilienM | nova is not used to spawn the overcloud | 14:53 |
| johnthetubaguy | dansmith: its odd we don't see 401 in the placement logs, or is that normal? | 14:53 |
| EmilienM | we use nodepool to spawn the subnode2 | 14:53 |
| dansmith | johnthetubaguy: I dunno | 14:53 |
| cdent | ks_exc.Unauthorized means two things | 14:53 |
| EmilienM | if you want to read logs from a real undercloud that spawns an undercloud, please look OVB jobs: https://review.openstack.org/#/c/430571/ | 14:53 |
| mordred | cdent: of course it does | 14:53 |
| johnthetubaguy | I wonder if its not actually got the correct url from the service catalog, or maybe it just can't talk to keystone to get it? | 14:53 |
| cdent | one of them is entirely driven by code, not a response from anything | 14:53 |
| dansmith | johnthetubaguy: placement access log on the undercloud is zero bytes, but we do have a few gets in the overcloud log | 14:53 |
| cdent | mordred: ikr | 14:53 |
| johnthetubaguy | dansmith: looks like they are the scheduler calls that work, yeah | 14:54 |

| johnthetubaguy | dansmith: well the empty list would give us the no-valid host error I think | 14:54 |
| EmilienM | I don't think it can comes from HAproxy because nova-placement-api log file exists, so API was reached | 14:54 |
| EmilienM | it can be in credentials, I'm checking now. | 14:54 |
| dansmith | actually, placement access is not zero bytes, it just looks empty | 14:55 |
| EmilienM | johnthetubaguy: you said you checked in keystone logs, did you see something? | 14:55 |

| EmilienM | that's useful feedback, I'll take some actions | 14:57 |

| EmilienM | would it recheck later? | 14:58 |
| mriedem | the compute will keep trying | 14:59 |
| johnthetubaguy | 2017-02-08 06:40:29.306 is first request | 14:59 |
| mriedem | the scheduler will keep trying to, but not per request | 14:59 |

| EmilienM | oh wait no, it's for regionOne/nova::compute | 15:00 |
| EmilienM | not placement | 15:00 |

| EmilienM | since ocata-3 actually | 15:08 |
| EmilienM | cdent, owalsh : is the POST means we're good? | 15:09 |

| *** mvk has quit IRC | 15:14 | |
| dansmith | where are the package build logs so we can see the nova hash being tested? | 15:14 |
| mriedem | EmilienM: if the tripleo jobs pin nova at certain points, how do the tripleo jobs in nova's experimental queue actually test the nova change? | 15:15 |
| EmilienM | cdent: rc1 is stable/ocata for nova. In tripleo we don't have stable/ocata yet | 15:15 |
| EmilienM | mriedem: they build it, the pin doesn't work | 15:15 |
| EmilienM | mriedem: so we build nova from master in that case | 15:15 |
| *** alexpilotti has quit IRC | 15:16 | |
| dansmith | EmilienM: so a change against tripleo tests against the pin and a change against nova tests against master+change ? | 15:16 |

| owalsh | ...and get arrested with a suitcase full of coke IIRC | 15:18 |
| mdbooth | siva_krishnan: Something lyarwood was trying to do with rescue was simply add an alternate boot image and set it as the boot volume. For unrescue we do the reverse operation. IIRC this also makes live-migration pretty simple to fix. | 15:18 |

| mdbooth | +1 agreed :) | 15:21 |
| dansmith | mriedem: oh right, I've been thinking of rc1 not o3 | 15:21 |
| mriedem | mdbooth: i think there is already a spec for that... | 15:21 |

| mriedem | mdbooth: that was accepted in newton, didn't make it, then when reviewing the spec again for ocata i raised some issues | 15:22 |

| raj_singh | Hopefully we can resolve the conflict and push it forward | 15:24 |
| EmilienM | maybe there is something the packaging building tool is missing | 15:24 |

| *** lucas_ has joined #openstack-nova | 15:25 | |

| mdbooth | raj_singh: Yeah, that's cool. I still wonder if this needs a spec, though. Doesn't seem very 'architectural', just a bunch of implementation detail. That's not what mriedem is saying, though, so I suggest you don't listen to me :) | 15:25 |

| EmilienM | owalsh: during your irc away, I decided to recheck the CI job to see if it's consistly failing and unpin Nova in RDO in a few time. So we'll be able to see how things work in our promotion job because I have some doubts about CI results. If you look 429008 - it passed tripleo some ovb & multinode jobs | 15:32 |
| siva_krishnan | mriedem I saw your comments on previous patch. you wanted a rpc call to check compute capabilities to live migrate instance. As we are already doing it pre live migrate check, would that be really necessary at API level? | 15:32 |

| cdent | johnthetubaguy: it sounds like we have insufficient data to say much of anything :( | 17:40 |
| johnthetubaguy | cdent: thats more accurate | 17:41 |
| cdent | we can't fully articulate what is different from attempt to attempt | 17:41 |
| dansmith | cdent: if it passes some of the time and doesn't other times, I think that's the definition of a race :) | 17:41 |
| cdent | just that things are different | 17:41 |
| cdent | dansmith: "unpinned nova" | 17:41 |
| dansmith | cdent: this was on the run to unpin nova yes? it failed once, and passed on a recheck | 17:41 |
| cdent | Oh, I didn't get that from what EmilienM said. Was it the exact same stuff in each run? I thought not? | 17:42 |
| *** adrian_otto has quit IRC | 17:42 | |
| *** Swami has joined #openstack-nova | 17:42 | |
| dansmith | that's my understanding of it | 17:42 |
| * cdent looks at EmilienM | 17:42 | |
| cdent | Because if you're right dansmith then I think EmilienM is going to the g&t's early, because we've learned nothing. | 17:43 |
| dansmith | maybe I misunderstood this: | 17:44 |
| dansmith | [07:27:24] <EmilienM>dansmith: ok I'm doing recheck and in 40m if I still see multinode failing, I'll unpin Nova in RDO and see how it goes | 17:44 |
| *** ociuhandu has joined #openstack-nova | 17:44 | |
| dansmith | I thought he meant he was rechecking the unpin | 17:44 |
| EmilienM | I did the recheck and it passed | 17:44 |
| EmilienM | which means, I could deploy tripleo with nova from master | 17:44 |
| *** vsaienko has joined #openstack-nova | 17:45 | |
| EmilienM | so we're unpinning now in RDO and i'll check how tripleo work | 17:45 |
| EmilienM | we should know in ~1h | 17:45 |
| EmilienM | cdent: if I see you offline, i'll just email you | 17:45 |
| cdent | EmilienM: when you did the recheck, was that the exact same code (everywhere) as earlier in the day, or some other code? | 17:45 |

| *** sudipto_ has quit IRC | 17:46 | |
| dansmith | I don't even understand how 430571 tests anything different actually | 17:46 |
| dansmith | it depends on the wsgi patch | 17:46 |
| dansmith | but nothing to unpin nova afaict | 17:46 |
| dansmith | even though it says it does | 17:46 |
| *** smatzek has joined #openstack-nova | 17:46 | |
| EmilienM | cdent: the exact same in theory | 17:48 |
| cdent | "in theory"? | 17:48 |
| *** tblakes has quit IRC | 17:48 | |
| EmilienM | yeah, the version of openstack-nova rpm was the same | 17:48 |
| dansmith | it doesn't depend on the wsgi patch actually | 17:48 |
| dansmith | it depends on the nova canary that was depending on the wsgi patch | 17:48 |
| EmilienM | but 'delorean' builds packages from git master so maybe something merged in the meantime? | 17:48 |
| EmilienM | dansmith: yeah it's a canary | 17:48 |
| dansmith | EmilienM: but why depend on the nova patch that does nothing from the tripleo patch? | 17:49 |
| EmilienM | dansmith: to run a job that didn't run in nova gate | 17:49 |
| EmilienM | dansmith: ovb-ha | 17:49 |
| EmilienM | check experimental in nova doesn't run ovb-ha | 17:49 |
| dansmith | EmilienM: how does the depends-on accomplish that? | 17:49 |
| *** derekh has quit IRC | 17:50 | |
| dansmith | EmilienM: I don't think anything is likely to have merged related to this in the last few hours, and even still, if you're not testing the rc1 branch you're not testing ocata anyway | 17:50 |
| *** gouthamr has quit IRC | 17:50 | |
| EmilienM | dansmith: our Ci tooling read Zuul env and build packages | 17:50 |
| dansmith | EmilienM: if you wanted the nova experimental job to run on the tripleo change the depends-on should go the other way no? | 17:51 |
| EmilienM | dansmith: right, gimme some hours to figure if it works now and if it's not racy & if it's stable | 17:51 |
| *** adrian_otto1 has quit IRC | 17:51 | |

| gabor_antal | And built mine on the top of it: https://review.openstack.org/#/c/431030/ | 18:20 |
| dansmith | cfriesen: yeah, it probably did drop a little of that, although libvirt was spawn'ing in its driver too, so just adding those to the helper thread might affect more behavior than you expect | 18:22 |
| cfriesen | dansmith: looking at @wrap_instance_event in particular, won't that generate start/finish events potentially before we even do any work? | 18:24 |
| dansmith | cfriesen: yeah, but that didn't wait until it was complete before anyway because libvirt was doing its own spawn'ing | 18:24 |
| *** marst has joined #openstack-nova | 18:25 | |
| cfriesen | dansmith: fair enough, but we used to at least do the pre_live_migration stuff before that spawn in libvirt | 18:25 |
| *** aloga_ has quit IRC | 18:25 | |

| *** sree has joined #openstack-nova | 18:26 | |
| cfriesen | dansmith: the reason I noticed this was we tried using the same model with cold migrations, but got bit by no longer having the errors_out_migration wrapper | 18:26 |
| dansmith | cfriesen: looks like the other drivers were all synchronous, so maybe just moving it to the thread function would be okay, but it's definitely another change | 18:28 |

| mriedem | non-cloudy behavior? | 19:04 |
| mriedem | seems more cloudy than shelve... | 19:04 |
| mriedem | the combination of ways to boot from volume and attach block devices is insane though | 19:05 |
| dansmith | to me, bfv is 100% non-cloudy | 19:05 |
| dansmith | so I'm not sure how something can be less cloudy | 19:05 |
| dansmith | equally uncloudy perhaps | 19:05 |
| mriedem | because there is a volume involved? | 19:06 |
| alaski | I think it would be a perfectly cromulent feature if Nova was not involved in managing the lifecycle of the volume at all | 19:06 |
| *** vsaienko has quit IRC | 19:07 | |
| dansmith | no, volumes are fine | 19:07 |

| dansmith | cfriesen: volumes are for storing persistent data, bfv is for building instances with configured state i.e. not repeatable, and not cattle | 19:19 |
| dansmith | cfriesen: no you can commit the same crime with a knife as a gun | 19:19 |
| jaypipes | cfriesen: volumes used as persistent storage of your data is still cloudy. boot-from-volume isn't cloudy because you're coupling your application state with your configuration state. | 19:19 |
| jaypipes | cfriesen: and what dansmith said :) | 19:20 |
| dansmith | exactly | 19:20 |

| cfriesen | jaypipes: dansmith: what if you didn't store everything on the boot volume? I mean you could still bfv and then attach a separate volume for persistant data. This might be useful in an environment with little local storage on the compute nodes. | 19:24 |
| cfriesen | (probably not the common case though) | 19:24 |
| *** erlon has joined #openstack-nova | 19:25 | |

| cfriesen | if I do a "nova delete" on an instance with a mounted cinder volume, is it guaranteed to do a clean shutdown or do I need to do a "nova stop" first to avoid potential disk corruption? | 20:31 |
| mriedem | cfriesen: you shouldn't need to stop a vm before deleting it | 20:32 |
| sdague | mriedem: clean shutdown I think was the critical bit | 20:32 |
| mriedem | hey, i didn't say it "worked" | 20:33 |
| *** bvanhav has quit IRC | 20:37 | |
| *** amoralej is now known as amoralej|off | 20:39 | |
| cfriesen | mriedem: sdague: looking at the code, the "nova delete" path calls guest.poweroff(), which calls self._domain.destroy(). The libvirt docs say it sends a SIGTERM then after a "reasonable timeout" a SIGKILL, but that timeout appears to be really small. | 20:40 |
| cfriesen | okay, the libvirt docs describe a virDomainDestroy as the equivalent of having the virtual power cord pulled, so not exactly safe | 20:41 |
| *** jaosorior has joined #openstack-nova | 20:42 | |
| melwitt | cfriesen: I just got to the same conclusion. apparently the VIR_DOMAIN_DESTROY_GRACEFUL flag should be used with destroyFlags to avoid possible corruption. but in that case, it could return an error instead of doing the destroy | 20:42 |
| cburgess | cfriesen Yeah I would say if the concern is data integrity on the volume, you should do a stop first. | 20:42 |

| openstackgerrit | Maciej Szankin proposed openstack/nova master: WIP conf: remove invalid TODOs https://review.openstack.org/428811 | 20:44 |
| dansmith | I really thought we did a graceful shutdown even on delete | 20:45 |
| mriedem | "Once this patch is in, the recommended method for applications to call virDomainDestroyFlags will be with VIR_DOMAIN_DESTROY_GRACEFUL included. If that fails, then the application can decide if and when to call virDomainDestroyFlags again without VIR_DOMAIN_DESTROY_GRACEFUL (to force the issue with SIGKILL)." | 20:45 |
| mriedem | so, if we have attached volumes, do a graceful destroy, else we don't care? | 20:45 |
| openstackgerrit | Artom Lifshitz proposed openstack/nova master: api-ref: Add tags to server(s) detail response https://review.openstack.org/431149 | 20:45 |
| cburgess | dansmith Well we do... but its just not very graceful | 20:45 |
| gatuus | virsh stop vs virsh destroy | 20:45 |
| dansmith | cburgess: I'm talking about an acpi event | 20:46 |
| cburgess | dansmith ahh oh no sorry according to cfriesen we don't my bad. | 20:46 |
| cburgess | dansmith Oh... no I think thats only on stop. I suppose we could call stop first from destroy if the power state is not already stopped or errored. | 20:46 |
| cburgess | mriedem I think ^^ is a better idea. | 20:46 |
| dansmith | I know it was part of phil's original blueprint, but maybe it never got implemented | 20:47 |
| dansmith | I know we do on stop | 20:47 |
| cburgess | The stop logic today as I recall (and reboot) is to send the ACPI event, wait some period of time, and then go hard kill. | 20:47 |
| dansmith | and didn't originally | 20:47 |
| cfriesen | mriedem: yeah, I think that'd make sense to use VIR_DOMAIN_DESTROY_GRACEFUL if we have attached volumes. | 20:47 |
| *** ducttape_ has quit IRC | 20:47 | |
| cburgess | cfriesen Why not call stop internall? That already has logic to attempt to gracefully stop and if that fails hard kill. Then do the cleanup in destroy. | 20:47 |
| cfriesen | dansmith: on stop we currently use virDomainShutdown first, then virDomainDestroy | 20:47 |
| dansmith | cfriesen: I know | 20:48 |
| cfriesen | cburgess: there's no need for a graceful stop if there are no attached volumes | 20:48 |
| gatuus | even virsh will not allow such a corruption | 20:48 |
| cfriesen | cburgess: but yeah, we could make it do a shutdown the same way we do for "nova stop" | 20:48 |
| cburgess | cfriesen I agree but again rather then having different logic for being graceful, why not simple say if volumes, call stop, then destroy. | 20:48 |
| cburgess | cfriesen Right. Then we don't have to implement a 2nd 'be graceful' routine. | 20:49 |

| *** crushil has quit IRC | 20:50 | |
| cfriesen | okay....does this need a spec, just a blueprint, or is it a bugfix? | 20:50 |
| dansmith | it's not just a bugfix, IMHO | 20:50 |
| dansmith | and I'm not sure we can call stop without some real refactoring | 20:51 |
| cburgess | That might true | 20:51 |
| cburgess | Some of the logic might need to come out into its own function that can be shared with destroy | 20:51 |
| melwitt | does mounting a volume in the vm mean it has to be attached from nova's perspective? like mounting of a shared drive? | 20:51 |
| openstackgerrit | Artom Lifshitz proposed openstack/nova master: api-ref: Add tags to server(s) detail response https://review.openstack.org/431149 | 20:52 |
| cfriesen | melwitt: you're thinking some non-cinder volume? | 20:52 |
| melwitt | cfriesen: yeah | 20:52 |
| cfriesen | melwitt: right, for something like that you'd want a clean shutdown even if there aren't any cinder volumes attached. | 20:53 |
| melwitt | I was thinking, is there a case where checking nova for "if volumes" isn't enough and if we should just do the graceful destroy regardless | 20:53 |
| dansmith | if a cinder volume is attached from nova's perspective, we have to assume it's mounted or dirty | 20:53 |
| cfriesen | melwitt: at the same time I could see a useful purpose for a "just kill it dead instantly" command | 20:54 |
| dansmith | right, I mean if we care about the data, we have to assume the above | 20:54 |
| dansmith | if we're told not to, then we could kill it outright | 20:54 |
| cfriesen | do we need a "nova delete --hard" option? (or a --soft and default to hard)? | 20:55 |
| dansmith | well, delete is kinda always documented as hard | 20:55 |
| dansmith | the most compatible thing would be a delete --soft, IMHO | 20:55 |
| dansmith | or just stopping the instance yourself first | 20:56 |
| dansmith | but we love pets around here, so.. | 20:56 |
| *** salv-orlando has quit IRC | 20:56 | |
| melwitt | fwiw, from a user perspective I would have expected a graceful delete by default. if anything in there was mounted | 20:56 |
| cfriesen | heh...honestly if we're not going to default to soft, then I don't see much gain since we can just stop it first | 20:57 |
| mriedem | until you forget to do soft first, | 20:57 |
| mriedem | or didn't know you needed to, | 20:57 |
| mriedem | and now your attached volume is corrupted | 20:57 |
| mriedem | and you curse openstack and use aws | 20:57 |
| cfriesen | yeah, it's a bit gross that attached cinder volumes get corrupted | 20:57 |
| mriedem | s/soft/stop/ | 20:58 |
| dansmith | to be clear, I think it's only application-level state, | 20:58 |
| melwitt | I guess that means it doesn't detach them first before destroying | 20:58 |
| dansmith | libvirt will still honor the write semantics of the block device I think | 20:58 |
| dansmith | so the filesystem should be okay | 20:58 |
| cfriesen | anything cached in the guest may get lost | 20:58 |
| smcginnis | Depends on what IOs are in flight I think. | 20:58 |
| dansmith | cfriesen: just like a power outage | 20:59 |
| cburgess | dansmith That depends on how you mount the FS inside the VM really. | 20:59 |
| cfriesen | but that should be okay assuming proper locking | 20:59 |
| dansmith | cburgess: you mean "safely" or not? :P | 20:59 |
| smcginnis | Unless the OS knows to flush its IO cache, filesystem or anything could get messed up. | 20:59 |
| cburgess | dansmith Yes. Its stupid.. but it does happen | 20:59 |
| cburgess | I feel like a best effort to gracefully stop first is a good idea. But I agree its probably a blueprint. | 20:59 |
| dansmith | smcginnis: the only way to safely do it at all is with libvirt honoring disk-like cache semantics and using a proper filesystem config so that works anyway | 20:59 |
| dansmith | smcginnis: otherwise you're running raid with memory cache and no battery | 20:59 |
| mriedem | melwitt: we destroy the guest before we detach the volumes in _shutdown_instance | 21:00 |
| dansmith | cburgess: it's just a change in behavior from right now, whereas we could add it for people that know, is all | 21:00 |
| melwitt | mriedem: a-ha, okay | 21:00 |

| dansmith | cburgess: but agree it probably should have been this way from the beginning | 21:01 |
| cburgess | dansmith Can't we just handle that with release notes? | 21:01 |
| dansmith | cburgess: it should be a blueprint regardless of the default, IMHO | 21:01 |
| dansmith | cburgess: lol | 21:01 |
| cburgess | I mean we can add a flag I guess. | 21:01 |
| cburgess | I know sdague will kill me for suggesting a flag. | 21:01 |
| mriedem | no config options | 21:01 |
| cburgess | Apparently mriedem too | 21:01 |
| cburgess | :P | 21:01 |
| dansmith | I'm not -2 on changing the default, I'm just not as up in arms about the current default | 21:01 |
| dansmith | but I treat my data nicely, so | 21:02 |
| melwitt | graceful destroy by default seems reasonable to me. I don't think we need a config option | 21:02 |
| sdague | I think we've been back and forth across that line a bunch in the past | 21:03 |
| cburgess | I agree it *should* be the default but if there is complaint I feel a config option is reasonable. Then again config options are so out of fashion now. | 21:03 |

| dansmith | cburgess: were definitely not doing a config option :) | 21:03 |

| mriedem | i think of delete as 'get rid of this instance' but also, don't mess up all my crap that's attached to it unless you're also deleting that, like volumes and ports | 21:10 |
| cfriesen | isn't the default shutdown timeout 60 sec? | 21:10 |
| melwitt | 2 minutes for windows update, that's generous (to think it would be that short) | 21:10 |
| dansmith | melwitt: I know, 2 minutes is laughable | 21:11 |
| sdague | melwitt: once upon a time there was 120 timer here | 21:11 |
| dansmith | mriedem: "mess up my crap" is relative though. it won't corrupt the filesystem | 21:11 |
| sdague | and it did do all sorts of oddity in the gate, because cirros totally ignores acpi | 21:11 |
| sdague | so we were hanging around forever | 21:11 |
| dansmith | mriedem: if your app corrupts your data on this event, then it also corrupts your data if the power goes out in the datacenter, so.. meh | 21:11 |
| mriedem | i vaguely remember that, | 21:11 |
| mriedem | didn't we revert Phil's like 1K LOC patch or somethign? | 21:12 |
| melwitt | if it were called 'nova pull-the-power-cord' that would be clear to me :P | 21:12 |
| mriedem | dansmith: true | 21:12 |
| sdague | mriedem: maybe, I don't remember exactly how long it was around | 21:12 |
| dansmith | sdague: ah, that's what I was thinking of | 21:12 |
| melwitt | yeah, I can see both arguments | 21:12 |
| mriedem | so at what point so volume multi-attach fix all of this? :) | 21:12 |
| mriedem | s/so/does/ | 21:13 |
| *** tbachman has quit IRC | 21:13 | |
| * melwitt hides | 21:13 | |
| sdague | so, if it was a thing... (which I'm still not convinced it should be) it definitely doesn't seem like a system wide answer is the right answer | 21:13 |
| dansmith | mriedem: volume multiattach asumes you don't have an app that would corrupt things like this, so that's a good argument for not caring IMHO :) | 21:13 |
| sdague | it would be image based or instance based metadata for shutdown time | 21:13 |
| sdague | so windows people could tune it up to 20 minutes for snowflakes | 21:14 |
| dansmith | image.I_suck=True | 21:14 |
| cfriesen | sdague: you mean like os_shutdown_timeout ? | 21:14 |
| sdague | cfriesen: maybe, that already in there? | 21:14 |
| cfriesen | sdague: yep | 21:14 |
| sdague | that vaguely sounds familiar | 21:14 |
| *** jdurgin has quit IRC | 21:14 | |
| dansmith | lol | 21:14 |
| sdague | ok, probablem solved! | 21:14 |
| dansmith | unfuckingbelievable | 21:14 |
| dansmith | I want my 20 minutes back | 21:15 |
| melwitt | hahaha | 21:15 |
| cfriesen | sdague: well, except it's only for shutdown, not for delete | 21:15 |
| sdague | cfriesen: ok, but that means there is still a way for you to get what you want right? | 21:15 |
| dansmith | ah, so setting it doesn't imply the different behavior on delete | 21:15 |
| sdague | delete is delete | 21:15 |
| cfriesen | dansmith: correct. sdague: I can manually do a nova shutdown before doing a delete, sure. | 21:16 |
| *** lucas_ has quit IRC | 21:16 | |
| mriedem | we don't check the image meta / extra spec for that on delete, only stop | 21:16 |
| dansmith | right | 21:16 |
| *** lucas_ has joined #openstack-nova | 21:16 | |
| mriedem | but we could... | 21:16 |
| sdague | ok, so I feel like thats fine then, there is an API people can use if they want the behavior | 21:16 |
| mriedem | w/o new API parameters | 21:16 |
| dansmith | sdague: agreed | 21:16 |
| dansmith | sdague: we knew stop does what we want, but didn't know it was configurable timeout, which makes it even more useful for the thing | 21:17 |
| mriedem | i always forget image_meta/extra_specs | 21:17 |
| sdague | mriedem: well, they also aren't hugely tested | 21:17 |
| mriedem | sdague: neither are the 5K config options | 21:17 |
| dansmith | I think you mean bigly | 21:17 |
| mriedem | but i tend to think of them in the same way | 21:17 |
| cfriesen | sdague: maybe we document that "nova delete" is explicitly a hard shutdown, and may result in data loss unless the guest flushes disks first? | 21:17 |

| sdague | http://developer.openstack.org/api-ref/compute/?expanded=stop-server-os-stop-action-detail,delete-server-detail#delete-server | 21:19 |
| sdague | "By default, the instance is going to be (hard) deleted immediately from the system" | 21:19 |
| sdague | it could be tightened up for sure | 21:19 |
| dansmith | By default, the instance is going to be (hard) deleted immediately | 21:19 |
| dansmith | yeah | 21:19 |
| mriedem | oh nice | 21:19 |
| melwitt | yeah, I think it wouldn't hurt and only help to add that bit of additional obvious info | 21:19 |
| mriedem | "With correct permissions, you can see the server status as" | 21:19 |
| mriedem | AS WHAT?! | 21:19 |
| melwitt | it's a secret! | 21:20 |
| sdague | mriedem: we have the best statuses | 21:20 |
| *** lucas_ has quit IRC | 21:20 | |
| mriedem | i paid for the whole seat but only need the edge | 21:20 |
| dansmith | that's true, if you really want this a an op, you can turn on soft_delete for 2 minute reclaim | 21:20 |
| *** lucas_ has joined #openstack-nova | 21:20 | |
| sdague | dansmith: well... that's different yet again right? | 21:21 |
| sdague | That just defers the delete | 21:21 |
| sdague | it still hard deletes when it happens | 21:21 |
| mriedem | does it stop the instance? | 21:21 |
| dansmith | sdague: same effect I think, we shutdown the instance and then delete it two minutes later | 21:21 |
| sdague | I thought we just held | 21:21 |
| dansmith | I don't think it hard deltes at the beginng | 21:21 |
| sdague | it was more for the undelete case | 21:21 |
| dansmith | no, it doesn't keep running | 21:21 |
| dansmith | sdague: it is | 21:21 |
| dansmith | self.driver.power_off(instance) | 21:22 |
| mriedem | yup[ | 21:22 |
| dansmith | graceful shutdown, which will wait, and then soft_delete will reclaim in $interval | 21:22 |
| mriedem | was just looking at that | 21:22 |
| sdague | ah, ok | 21:23 |
| mriedem | i was recently complaining about reclaim_instance_interval | 21:23 |
| mriedem | but in my old age i've forgotten why | 21:23 |
| dansmith | because it's stupid? | 21:23 |
| mriedem | well, my complaint was if you set reclaim_instance_interval in the api but not on the compute hosting the instance, the instance won't actually be deleted | 21:24 |
| mriedem | but, we assume you don't do that | 21:24 |
| dansmith | ah yep | 21:24 |
| mriedem | we assume you've correctly configured nova.conf's 5K options and deployed it correctly on all of your services | 21:24 |
| mriedem | oops mine just blew off your toe! | 21:24 |
| mriedem | at some point i think capabilities will bridge that gap | 21:25 |
| mriedem | since the api could tell what the capabilities are on the host | 21:25 |
| cfriesen | looks like only xen supports soft delete | 21:25 |
| cfriesen | oh, I guess we fall back to just power_off | 21:26 |
| dansmith | cfriesen: we fall back to poweroff if the driver doesn't do anything | 21:26 |

| sdague | mriedem: so... if we aren't doing a microversion then we are backporting to all active stable branches right? | 21:35 |
| mriedem | sdague: that was my plan yes | 21:35 |
| sdague | including mitaka? | 21:36 |
| mriedem | that was my plan yes | 21:36 |
| sdague | if you are going to take it back to there, I'd be fine with it | 21:36 |
| mriedem | ok | 21:36 |
| sdague | it definitely is a bug to have busted that | 21:36 |
| mriedem | when mordred and dhellmann were reporting it, they said it used to work, which i assume meant when they were talking to older clouds that were only exposing v2 | 21:37 |
| mriedem | and i also assume that most clouds are around 18 months behind trunk | 21:37 |
| dhellmann | yes, it works on dreamhost's deployment but not devstack | 21:37 |
| dhellmann | I believe dreamhost is running newton by now | 21:37 |
| mriedem | we dropped the v2 code in newton, | 21:38 |
| mriedem | so i doubt it | 21:38 |
| dhellmann | oh, maybe not then | 21:38 |
| dhellmann | last I heard they were upgrading, but maybe they haven't rolled out the results | 21:38 |
| dhellmann | it's likely mitaka, then | 21:38 |
| sdague | mriedem: yeh | 21:38 |
| dhellmann | I can find out if it's important | 21:38 |
| mriedem | i don't think it's hugely important | 21:38 |
| sdague | mriedem: yeh, I do assume that same kind of delay | 21:38 |
| *** foexle has quit IRC | 21:39 | |
| sdague | so covering the bases across 4 releases with the fix, it's probably good enough for folks | 21:39 |
| sdague | mriedem: we should make a pretty big release note on the stable branches so it's clear to people we're restoring previous behavior | 21:39 |
| *** salv-orlando has joined #openstack-nova | 21:40 | |
| mriedem | sdague: i can put the release note in this change itself | 21:40 |
| mriedem | i thought about that actually but apparently forgot | 21:40 |
| sdague | mriedem: that's fine as well | 21:40 |
| sdague | on master, I'm slightly less concerned | 21:40 |
| *** marst has quit IRC | 21:41 | |
| sdague | but the api fix on stable is a little bigger of a thing, because the behavior we are trying to do is get ahead of people before they upgrade, or if they upgraded, get them to bump to latest on their stable branch | 21:41 |
