| whoami-rajat | sfernand, thanks | 14:08 |
| whoami-rajat | #link https://etherpad.opendev.org/p/antelope-ptg-cinder-planning | 14:08 |
| whoami-rajat | we've some topics added to the etherpad, which is good but please try to add it as soon as possible since we've very less time | 14:09 |
| whoami-rajat | if anyone has any topic i mean ^ | 14:09 |
| whoami-rajat | I've allocated 4 hours everyday in the PTG schedule | 14:09 |
| whoami-rajat | the last hour will be flexible if the discussions extend or for other purposes | 14:10 |
| whoami-rajat | #link https://ptg.opendev.org/ptg.html | 14:10 |
| whoami-rajat | I still need to update few things like the etherpad and video meeting link but generally we will be meeting 1300-1700UTC everyday from 18-21 Oct | 14:11 |
| harshailani | okie | 14:11 |
| rosmaita | the TC & Community meetup is 1500-1700 UTC on monday | 14:12 |
| whoami-rajat | also we won't have upstream meeting next week for obvious reasons but i will send out a mail for that next week | 14:12 |
| whoami-rajat | rosmaita, yes | 14:14 |
| whoami-rajat | this is the etherpad for the same | 14:14 |
| whoami-rajat | #link https://etherpad.opendev.org/p/tc-leaders-interaction-2023-1 | 14:14 |
| whoami-rajat | so go through the PTG schedule for the sessions you would like to attend | 14:14 |
| *** dasm|off is now known as dasm | 14:15 | |
| whoami-rajat | next is a related announcement, we've shifted the operator hour from 1400 UTC to 1500 UTC on tuesday since there was a conflict with nova | 14:15 |
| whoami-rajat | that's all i had for the announcements | 14:17 |
| whoami-rajat | does anyone have anything else to announce? | 14:17 |
| whoami-rajat | guess not | 14:18 |
| whoami-rajat | let's move to topics then | 14:18 |
| whoami-rajat | #topic extending attached volumes for remotefs drivers | 14:18 |
| whoami-rajat | kgube, that's you | 14:18 |
| kgube | alright | 14:18 |
| kgube | remotefs drivers resize their volume files with qemu-img | 14:19 |
| kgube | which does'nt work for attached volumes because qemu locks the files | 14:19 |
| kgube | (which is a good thing, concurrent updates to qcow2 can corrupt the file) | 14:20 |
| kgube | the qemu monitor supports a block-resize command that can be used to resize attached disk images | 14:21 |
| kgube | nova already makes this available through the external server event API | 14:22 |
| felipe_rodrigues | we have a patch: https://review.opendev.org/c/openstack/cinder/+/739079/ | 14:22 |
| kgube | but there is no feedback on the success of the resize operation | 14:23 |
| kgube | I've submitted a nova-spec that proposes a new synchronous API that would give feedback | 14:23 |
| kgube | but I'm not sure if this the correct approach | 14:23 |
| kgube | https://review.opendev.org/c/openstack/nova-specs/+/855490 | 14:24 |
| kgube | this is the spec | 14:24 |
| eharney | it seems like a reasonable idea, similar to how we do assisted snapshots | 14:25 |
| kgube | one big question is, is it okay to do this synchronously? | 14:26 |
| whoami-rajat | I don't think cinder has any mechanism like external events in nova to accept updates asynchronously | 14:27 |
| eharney | we made one for assisted snapshots, could have a similar mechanism for this | 14:28 |
| whoami-rajat | ok | 14:28 |
| kgube | there are callbacks, like os-migrate_volume_completion | 14:28 |
| eharney | i'm unsure about it being synchronous when it comes to handling NFS errors that could take minutes to recover from | 14:29 |
| eharney | yeah | 14:29 |
| whoami-rajat | kgube, yeah, forgot about the migration case, we can do it like that as well | 14:29 |
| kgube | if we need a callback then it might not even be necesserary to add a new nova API | 14:30 |
| kgube | and we could keep the external server event to trigger it | 14:30 |
| kgube | eharney, are NFS errors a common thing? | 14:31 |
| eharney | probably common enough that we should consider what cleanup is required if this fails part-way through | 14:32 |
| kgube | qemu disables preallocation for block-resize, so it should always be fast otherwise | 14:32 |
| kgube | and then there is a pretty dirty alternative, which would be polling "qemu-img info" on the volume file until the size is the expected one | 14:34 |
| kgube | but it wouldn't require any API change at all | 14:35 |
| kgube | but failure would only be detectable by timeout | 14:37 |
| eharney | is there a path in nova that resizes the volume if it's attached to nova but the instance isn't running? iirc we have that for other operations | 14:39 |
| whoami-rajat | i think we use the polling mechanism for online snapshot creation but I think there were concerns raised to that approach and moving it to external events | 14:39 |
| eharney | yes, there are better ways to handle the info updates about assisted snapshots that didn't exist when it was created, it would be possible to rework that | 14:40 |
| kgube | eharney, there is no path yet, afaik | 14:41 |
| kgube | The patch that felipe_rodrigues posted tries always to resize attached volumes | 14:41 |
| kgube | and only handles them differently when they fail with the right error message | 14:42 |
| kgube | s/they fail/this fails/ | 14:42 |
| whoami-rajat | kgube, but nova can check if the guest is active and perform operations based on that right? | 14:42 |
| kgube | yeah | 14:43 |
| eharney | i'm not sure what happens when you resize the volume file while nova already has it partially attached.. | 14:43 |
| eharney | seems like it would cause problems ? | 14:43 |
| sfernand | Felipe proposed the idea to let Cinder handles the resize if the nova instance is shutdown by just trying and in case of a error check if qcow2 is locked | 14:43 |
| sfernand | what do yu mean by partially attached? | 14:44 |
| eharney | the stage between when nova gets info/metadata about the volume and when the attachment process is actually completed | 14:44 |
| eharney | or when the instance is shutoff but Nova still has an attachment record | 14:44 |
| eharney | something presumably has to let it know that the volume file size changed, because i think it's stored in the BDM | 14:45 |
| sfernand | i don't know for stage between metadata but we tested for the case where Nova was shutoff and it works fine | 14:45 |
| kgube | Yeah, thats the original purpose of the volume-extended external server event | 14:46 |
| sfernand | when nova is put back online the vm get the new size | 14:46 |
| kgube | eharney, to notify nova of a changed volume size, i mean | 14:46 |
| eharney | if you are using the code in patch 739079, does it send an external server event? | 14:47 |
| felipe_rodrigues | If I remember correctly, there is a problem with that approach when the VM is stopped ... The lock keeps there but the Nova does not extend | 14:47 |
| kgube | the event is always sent when extending attached v9olumes | 14:47 |
| kgube | felipe_rodrigues, oh, thats a problem | 14:48 |
| whoami-rajat | I don't feel good interrupting the discussion but I think this is something worth discussing in a PTG session with all the members around | 14:49 |
| whoami-rajat | since we've limited time here, and also another topic to discuss, it would be good to continue this during PTG | 14:50 |
| felipe_rodrigues | do we have a slot for this ? | 14:50 |
| whoami-rajat | #link https://etherpad.opendev.org/p/antelope-ptg-cinder-planning | 14:50 |
| eharney | yeah, i'm happy to help on this area where i can | 14:50 |
| whoami-rajat | felipe_rodrigues, a topic needs to be added and i will arrange a slot/schedule for topics with their respective date and time | 14:50 |
| jungleboyj | ++ | 14:50 |
| kgube | ++ | 14:51 |
| whoami-rajat | great, thanks for initiating this again kgube, let's move on to the next topic | 14:52 |
| whoami-rajat | #topic Outreachy applications started | 14:52 |
| whoami-rajat | enriquetaso, that's you | 14:52 |
| enriquetaso | hey | 14:52 |
| enriquetaso | Outreachy applicants period started this week (until the end of November). | 14:53 |
| enriquetaso | Because of that cinder channel is going to have some messages from potential interns. | 14:53 |
| enriquetaso | Most probably they are pinging me or Rajat but Please feel free to reply to them and help them with their cinder/devstack questions :D | 14:53 |
| jungleboyj | Cool. | 14:53 |
| enriquetaso | Thanks! | 14:53 |
| enriquetaso | that's all :P | 14:54 |
| enriquetaso | jungleboyj++ | 14:54 |
| harshailani | sure | 14:54 |
| whoami-rajat | thanks enriquetaso for mentoring the outreachy interns! | 14:54 |
| enriquetaso | thanks whoami-rajat for also mentoring! | 14:55 |
| whoami-rajat | :) | 14:55 |
| whoami-rajat | since we don't have any more topics, let's move to open discussion for last 5 minutes | 14:56 |
| whoami-rajat | #topic open discussion | 14:56 |
| sfernand | maybe a onboard session in ptg to would help them | 14:56 |
| jungleboyj | sfernand: That is a good idea. We haven't done an onboarding session for people in a while. | 14:56 |
| enriquetaso | when was the last time? | 14:56 |
| sfernand | some similar to what we did in the openstack day I don't know | 14:57 |
| sfernand | we could try defining a few topics, I could help with a quick overview on devstack | 14:57 |
| whoami-rajat | sfernand, jungleboyj good idea | 14:57 |
| jungleboyj | Well, the last time I did one was the first Berlin I think? | 14:57 |
| jungleboyj | I don't know that there has been one since? | 14:57 |
| simondodsley | jungleboyj: was that recorded and is it available? | 14:58 |
| rosmaita | we may have done one at shanghai but no one showed up | 14:58 |
| enriquetaso | sounds good, i'll look for a reference | 14:58 |
| enriquetaso | oh :/ | 14:58 |
| jungleboyj | I recorded one in the past. Let me Check YouTube. | 14:58 |
| enriquetaso | sfernand++ | 14:58 |
| sfernand | rosmaita: yes I remember that :P | 14:58 |
| rosmaita | other than that, i never did one as PTL | 14:58 |
| whoami-rajat | rosmaita, yeah, i remember doing one but don't remember any discussion from it, maybe that's why :D | 14:59 |
| rosmaita | so it's been quite a while | 14:59 |
| whoami-rajat | surely we can have a quick onboarding towards the start of PTG | 14:59 |
| whoami-rajat | and if sfernand would like to add a session with introduction to devstack or similar, we can find a slot for that as well | 14:59 |
| whoami-rajat | s/towards/at | 15:00 |
| sfernand | yes I can do that | 15:00 |
| whoami-rajat | great | 15:00 |
| whoami-rajat | so again reminding everyone to add topics to the planning etherpad | 15:00 |
| enriquetaso | thanks sfernand | 15:00 |
| whoami-rajat | https://etherpad.opendev.org/p/antelope-ptg-cinder-planning | 15:00 |
| jungleboyj | Sounds good. Even just a time at the beginning to see who is new. | 15:00 |
| enriquetaso | i can help with that | 15:01 |
| enriquetaso | maybe a cinder 101 too i don't know, | 15:01 |
| sfernand | enriquetaso: :) | 15:01 |
| whoami-rajat | jungleboyj, ++ enriquetaso ++ | 15:01 |
| whoami-rajat | time is up, thanks everyone, see you at the PTG! | 15:01 |
| simondodsley | I have people in India who would love those sessions, so please record them | 15:01 |
