claytonIs there any documentation on the recommended way to do upgrades to liberty for nova?  I've found the spec for the expand/contract stuff, but I don't know if that's currently recommended over just using nova-manage db sync00:20

bauwserpkoniszewski: AFAIK, we don't verify the Service version when live-migrating09:00
rdopieraI didn't know you can have mixed versions in your cloud in the long run09:00
*** vilobhmm11 has quit IRC09:00
pkoniszewskirdopiera: it can be a case even when upgrading09:00

bauwserpkoniszewski: good question, lemme think about that09:01
pkoniszewskibauwser: im just trying to figure out whether everything is working fine in LM in Mitaka09:02
alex_xutechnically I think it should works09:02
bauwserpkoniszewski: if pinning the RPC version to Liberty, then it just means that all the ocmputes will work like if they were Liberty09:02
bauwser(although it's now possible to ask 'auto' :) )09:02
bauwsernow, the compute/compute calls per conductor will also stay Liberty09:03
pkoniszewskiauto works only between Mitaka nodes, we block it in any other case09:03
bauwserpkoniszewski: so, yeah I think it's possible, that just means all your migrations will be Liberty-ish09:03

pkoniszewskibauwser: but the open question is if it is nova's policy to allow such operation09:13
bauwseryou mean, like an agreement ?09:14
bauwserwell09:14
bauwserIMHO, operators are fully responsible for upgrading their clouds and doing the necessary migrations if they want to09:14
bauwsersince the live-migration tool is admin only, I don't see the point to restrict the destinations09:15
pkoniszewskiyes, like an agreement09:15
pkoniszewskithat's what i think too09:16
bauwseroperators know their cloud better than us, and I'm thinking of good usecases where you'd still like to migrate to an older compute09:16
johnthetubaguyso we are meant to support all operations during an upgrade09:16
*** daemontool has joined #openstack-nova09:16
pkoniszewskii'm thinking of moving instances back in case of any problems with upgrade09:16
johnthetubaguythat should, in theory, work09:17
bauwserthat is one of my thoughts09:17
johnthetubaguylive-migrate isn't tested in grenade though09:17
pkoniszewskiokay, so let me give it a shot09:17
pkoniszewskijohnthetubaguy: yeah, i think would be great to have this tested09:17

markus_zclaudiub|2: What's the difference between the LP projects "compute-hyperv" and "os-win"? I'm asking because of  https://bugs.launchpad.net/nova/+bug/155569909:56
openstackLaunchpad bug 1555699 in OpenStack Compute (nova) "Hyper-V: failed cold migrations cannot be reverted" [Undecided,New]09:56
claudiub|2markus_z: hello. os-win is a cross-project library, currently used in nova, cinder, ceilometer, networking-hyperv, compute-hyperv, and, starting with newton, os-brick and maybe others. compute-hyperv is sort of a down-stream nova driver for hyper-v.09:58
*** andreykurilin has joined #openstack-nova09:58

claudiub|2it's basically the nova hyper-v driver + 10+ features.09:58

openstackgerritJohn Garbutt proposed openstack/nova: Use migrate_data.block_migration instead of block_migration  https://review.openstack.org/28736310:20
bauwserpkoniszewski: oh nevermind10:20
bauwserpkoniszewski: found it https://review.openstack.org/#/c/281812/10:21
* bauwser should be thinking of finding a way to check if a change is having another reno file 10:22
bauwserlike asking to provide the Change-Id in the reno change10:23
johnthetubaguybauwser: yeah, thats worth thinking about, it does feel a bit error prone right now10:23
bauwserfor the moment, the only way I can find those is grepping the existing notes for keywords10:24
bauwsermaybe I should ask dhellmann to have a specific field for a reno note providing the change-id10:25
johnthetubaguybauwser: in some metadata and not the text that gets included I guess?10:26
bauwserjohnthetubaguy: yeah, thinking of the SHA1s rather than Change-ID10:26
johnthetubaguybauwser: I like how that would let us reference a commit in a previous tag, and it could spot that, I guess10:26
*** mvk has joined #openstack-nova10:27
johnthetubaguyhmm, probably does have to be SHA I guess, as its branch specific, but yeah, will let the reno folks think about that10:27
bauwserjohnthetubaguy: it would be an optional metadata, the default being the current SHA110:27
johnthetubaguyoh, wait, a rebase would be horrid then10:27
bauwserjohnthetubaguy: no, because we would only provide the sha1 for reno changes not in the same patch10:28
johnthetubaguyoh, optional could work, I see what you mean10:28
johnthetubaguyyeah, its only needed when its static then, which is cool10:28
bauwserjohnthetubaguy: people providing a reno file with the same implementation change would use the current sha1 of the patch10:28

PaulMurraygood morning everyone10:33
bauwserjohnthetubaguy: now, my question is (because I'm definitely not a nova/cinder expert), what is happening if a cinder driver doesn't have support in os-brick atm ?10:33
johnthetubaguybauwser: I think we might still have some in tree drivers that don't use os-brick10:34
bauwseror rather, my question being : what's the key benefit for the users looking for this drivre?10:34
johnthetubaguybauwser: but I don't think we are allowing any new ones10:34
johnthetubaguybauwser: ah, I see10:34
sdaguemorning folks10:34
bauwserjohnthetubaguy: I mean, is that change a pure refactoring ?10:34
johnthetubaguybauwser: I think this one is a new driver that we added support for via os-brick?10:35
bauwserjohnthetubaguy: yup, just me wondering the impact10:35
PaulMurraysdague, you're kidding - you can't be up already ?10:36
johnthetubaguybauwser: without it, we don't support that cinder driver10:36
bauwserokay I see10:36
sdaguePaulMurray: it was an early night for us all last night. I'm definitely a morning person.10:36
bauwserjohnthetubaguy: so it wasn't supported before, using the legacy way of non-osbrick ?10:36
bauwserjohnthetubaguy: nevermind, found my answer https://review.openstack.org/#/c/253353/8/nova/virt/libvirt/driver.py10:37
johnthetubaguybauwser: yeah, you see the new type being added here, at least as I understand it, i.e. doesn't replace an existing one: https://review.openstack.org/#/c/253353/8/nova/virt/libvirt/driver.py@35010:37

sdaguehttps://github.com/openstack/nova/blob/59c9e57ecb0edf4e952e1d58782c9c75e7b329ad/nova/compute/manager.py#L243912:53
*** kaisers1 has joined #openstack-nova12:54
cdentin the prior code only one path did the cleanup because the call to resource tracker was in the calling code rather than the completion12:54
*** e0ne has quit IRC12:54
sdagueso, if anything fails there, we bail out12:54
sdaguesure12:54
*** e0ne has joined #openstack-nova12:54
sdaguebut the other cleanup path is only during compute manager start, right?12:55

cdentright two paths: one during compute manager startup, one during _delete_instance12:56
sdagueright12:56
cdentmy change doesn't change the behavior of the exception handling12:56
cdentthus my confusion with your question12:56
sdaguesure, it does mean if instance.destroy() throws an exception we don't do resource cleanup though12:56
sdaguewell, we don't call update_resource_tracker12:57
*** sheel has quit IRC12:57
cdentthat was always true12:57
cdentif the exception was before then12:57
sdaguesure12:57
cdentand in another bug there's a long discussion that when there was exceptions during such state we should not do cleanup, because we don't actually know what the state is and the resources may still be used even though we no longer have a resource object12:58
cdentso I chose to leave it conservative12:58
sdagueok12:58
cdentI can not that somewhere, but I'm not sure where/how, if you like12:59

sdaguepersonally I like to understand all the functional changes independently and them make sense. Then cross check them with the tests to make sure they do the thing I think the functional changes are supposed to be.13:05
cdentMakes sense. In this case I took the placement of the original call as a logical flaw and just moved it to the common path. Admittedly the code for this stuff is insane.13:07

johnthetubaguycdent: the resource tracker things like that are self healing, I was told, i.e. the next run will sort out what resources are used and updated things, I think. But its good to be explicit.13:13
*** y_sawai has joined #openstack-nova13:13
johnthetubaguyhang on, the line you are moving is the one that probably fixed that bug, maybe?13:13
sdaguejohnthetubaguy: yeh, that's what I'm thinking, based on the patch vishy had13:13
sdaguehttps://review.openstack.org/#/c/47504/1/nova/compute/manager.py13:14
sdagueI mean, I think moving that to complete is fine, as it means the compute manager cleanup puts things into a sane state faster13:14
cdentthe bug was the latency13:15
cdentnot that it was never happening13:15
sdaguehttps://review.openstack.org/#/c/47504/1/nova/compute/manager.py13:16

sdagueI added a comment to 4750413:16
*** tbachman has joined #openstack-nova13:17
*** y_sawai has quit IRC13:17
sdaguecdent: .... I'm confused. In your patch in the synchronous case the resource_tracker gets called later. So latency can only go up.13:17
sdagueit also adds a cleanup path for compute manager restart, but that's only going to be the case for things being in an inconsistent state, and nova-compute actually restarting by the admin13:18

cdentsdague, johnthetubaguy: okay, yes, when I worked on this I discovered that the bug was no longer valid, but it did point to a problem with the way that _complete_deletion was being used, so the options are: take the commit message as writ and remove the bug reference or leave the bug reference because it was semi-related13:23
*** diogogmt has quit IRC13:23
sdagueSo, I would13:23
cdent(the latency concern is a holdover from the original bug analysis, menal fart)13:23

bauwserso, tbc, this bug is related to the 60 secs window we have13:33
bauwserwhen someone deletes an instance, it can take up to 60 secs to get noticied13:33
kashyapcdent: On a related note, in Fedora-land, once N+2 is released, 'N' goes End-of-Life.  And, all bugs (that are not solved) reported against 'N' are closed, with a request to re-test them on N+2, and re-open it if the issue persists.13:33

sdagueyou are litterally saving the instance to the db and immediately updating the resource tracker with it13:36
ansiwenjohnthetubaguy: I think you mixed up two similar changes with your comment, can that be? https://review.openstack.org/#/c/28556213:36
bauwsercdent: the thing that we only update the RT when either every 60 secs, or when a claim is done means that when deleting an instance, you need to wait for the next loop13:36
bauwsercdent: which is fixed by your change13:37
johnthetubaguyansiwen: that happens more often than I would admit, let me check13:37

*** kmartin has joined #openstack-nova16:08
PaulMurrayso live means its alive16:08
dontrumpthe vm is not stopped while it's migrated during live migration16:08
dontrumpit is stopped during cold migration16:09
mmarinok that's why I have in French "migration à chaud" (hot migration kind of)16:09
bauwsermmarin: tout à fait16:09
dontrumpmmarin: if you're doing french translations for nova,16:09
dontrumpbauwser is your man16:09
mmarinok I was asking for live migration because I have "migration active", "migration à chaud" "migration en direct"...so we have to make it consistent at one point16:10
bauwsermmarin: nope, it's just that the user is not knowing that the VM is moved16:10
PaulMurraymmarin, yes, the main point for a user is the VM will be shutdown if its cold migration16:11
mmarinok16:11
bauwsermmarin: tbc, live migrations are only done by operators, so it's not something a guest would know16:11
bauwserit's transparent16:11
mmarinso you don't stop anything when you do a live migration, everything is still up and running16:11
PaulMurrayright16:12
bauwsercompared to a cold migration (migration à froid) which requests the guest OS to be stopped16:12
mmarinok so "migration à chaud" makes more sense then16:12
bauwserindeed16:12
bauwserall our migrations are "in direct", ie. not done in X hours16:12
mmarinok16:13
kashyapTo put another way: During live migration, the guest doesn't know it is being live migrated.  (At least unmodified guests.)16:13

*** tesseract- has quit IRC16:55
johnthetubaguybauwser: unsure if that works across branches, where we might have multiples? maybe thats a good thing?16:55
bauwserI need to think about the problem during the week-end16:56
dhellmannbauwser, johnthetubaguy : you can have the same change id across branches and repos, but not for 2 changes in the same branch16:56
bauwserdhellmann: johnthetubaguy: see https://review.openstack.org/#/q/3a761270581d1ac61a3b4669c130d211f1ad5a17,n,z16:56

superdanjohnthetubaguy: so we're not going to be able to land that neutron blocker migration until I assume weeks after newton opens because grenade takes a while to get updated16:57
superdanjohnthetubaguy: so I think we just need to be diligent about -2ing any new migrations until that time16:58

*** dims_ has joined #openstack-nova16:58

bauwserdhellmann: so, I was trying to think about how to find a separate reno change for an existing implementation change16:58
bauwserdhellmann: I can for sure grep that16:58
bauwserdhellmann: but I was thinking of something better than just that16:58

PaulMurraybauwser, what if you make a follow up change for the same note ?16:59
PaulMurraybauwser, say, correct a spelling mistake16:59
bauwserPaulMurray: that doesn't work if the reno change is far younger16:59
bauwserI mean, the problem is with the follow-up change, I want to find it17:00

*** haomai___ has quit IRC17:01
PaulMurraybauwser, anyway - I've got to go17:01
bauwseranyway, I fear I have to leave, just hearing screams behind me17:01
dhellmannbauwser : if your reno note comes in a later change, you can put the code change id into the commit message for the reno not, just don't use "Change-Id:" as a prefix.17:01
bauwserdhellmann: that's what I usually do17:01

bauwserdhellmann: but that's not perfect, and I can't expect all our proposers to do the same (and our reviewers to verify that)17:01
bauwserdhellmann: eg. https://review.openstack.org/#/c/291750/17:02
dhellmannbauwser : yeah. the intent was to require a reno file with the code change, but that's also not always easy to enforce17:03
dhellmannbauwser : if you know the name of the note file, you can query for patches containing that using the "path" search term17:03
bauwsersure, that's what I do, but that's painful17:04
johnthetubaguysuperdan: oooh, I forgot about the grenade dependency there, good point.17:04
superdanjohnthetubaguy: yeah, grenade is doing a real good job of making sure we don't land it because our services haven't been upgraded yet :D17:04
bauwserdhellmann: that said, my concern is the opposite, I'm starting from a list of changes not including a reno file (but should), and I'm trying to find whether someone already provided a follow-up patch with a reno file17:05
*** e0ne has quit IRC17:05
dhellmannoh, that's not an easy case17:05
bauwserdhellmann: since we're very close to the release, I'm trying to identify if we missed some notes17:05
bauwseryeah, I know17:05
bauwserso, usually, grep is my friend17:05
bauwserbut with the expansion of the number of relnotes, it'll become harder17:06
dhellmannbauwser : if you can think of anything we can add to reno's report or list commands to help with that, let me know. that would only help you with landed patches, though, I guess, not things up for review17:06
johnthetubaguysuperdan: damm those pesky tests working properly :)17:06
superdanjohnthetubaguy: yeah :)17:06
bauwserdhellmann: my original thought was to propose some contextual metadata attached to a note mentioning the implementation patchs' SHA1s (and defaulting to the current sha1) but that doesn't sound great17:07
dhellmannI'm not sure you can search file content through gerrit (maybe, I just don't know)17:08
dhellmannat that point you might as well put it in the commit message, though, right?17:08

ssgi changed the cpu allocation at nova.conf, then restart nova-scheduler an nova-compute service, but it still doesn't reflect the vcpu on hypervisor-show?23:31
claudiub|2i don't think it matters, nova-scheduler vs nova-compute node, they're separate entities.23:32
claudiub|2i think that hypervisor-show will return the raw view of the compute node23:33
ssgwhat do u mean raw-view?23:33
ssgwhat does the vcpus means in hypervisor-show?23:33
claudiub|2i mean, if the compute node reports 2 used vcpus, hypervisor-show will return 2 used vcpus.23:34
*** carl_baldwin has joined #openstack-nova23:34
ssgthere are two vcpus, one is "used", one is "available"23:35
*** pwnall has quit IRC23:35
ssgi change the ocvercommit ratio to 1023:35
ssgbut the availabe vcpus doesn't reflect as physicalx1023:35

*** pushkaru has quit IRC23:37

claudiub|2basically, each compute node can have its cpu_allocation_ration23:38
ssgi only have 1 compute host now23:39
ssgwhere is the value "per-aggregate" set?23:39
claudiub|2that is only applied if you have aggregates23:40
claudiub|2an aggregate is basically a logical grouping of compute nodes23:41
claudiub|2not really helpful to have an aggregate of 1 host. :)23:41

ssgi know. go back to my question.. why the  vcpus in hypervisor-show does't reflect my cpu-allocation value? ie. physical_corex1023:43

claudiub|2ssg: i dunno. but that doesn't mean you can't use physical_core x 10.23:47
*** erlon has quit IRC23:48
claudiub|2ssg: you can have a higher vcpus_used value than vcpus value. it takes that cpu_allocation_ratio into account.23:48
*** ljxiash_ has quit IRC23:51
ssgok. i found it.. the scheduler take the changes of the new overcommit ratio, but the api/hypervisor-show always reflect the physical core.23:51
ssgthat's a bit confusing though for user.23:51
