| whoami-rajat | hello everyone | 14:04 |
| whoami-rajat | and folks that are back from Vancouver PTG | 14:04 |
| helenadantas[m] | o/ | 14:04 |
| whoami-rajat | let's get started | 14:05 |
| whoami-rajat | #topic announcements | 14:05 |
| whoami-rajat | first, Spec freeze | 14:05 |
| whoami-rajat | The deadline for spec freeze is tomorrow i.e. 22nd June | 14:05 |
| whoami-rajat | #link https://etherpad.opendev.org/p/cinder-2023-2-bobcat-specs | 14:05 |
| nahimsouza[m] | o/ | 14:06 |
| whoami-rajat | we only have 1 remaining spec for this cycle | 14:06 |
| whoami-rajat | #link https://review.opendev.org/c/openstack/cinder-specs/+/868761 | 14:06 |
| whoami-rajat | i see Christian has addressed the recent comments | 14:07 |
| whoami-rajat | i will review the spec again | 14:07 |
| whoami-rajat | but other cores, if you get some time, please take a look at the spec ^ | 14:08 |
| whoami-rajat | since we only have 1 day | 14:08 |
| whoami-rajat | we might extend the deadline for this spec if it misses but it's always good to be on time | 14:08 |
| whoami-rajat | also don't want to have conflicts during implementation since it adds a new field to the volume response | 14:09 |
| whoami-rajat | better to have the discussion complete on the spec itself | 14:09 |
| whoami-rajat | moving on | 14:09 |
| whoami-rajat | we have M-2 coming up in 2 weeks | 14:10 |
| whoami-rajat | i.e. 6th July | 14:10 |
| whoami-rajat | we have the driver merge deadline on M-2 | 14:10 |
| whoami-rajat | #link https://etherpad.opendev.org/p/cinder-2023-2-bobcat-drivers | 14:11 |
| whoami-rajat | here is the list of drivers currently under my track | 14:11 |
| whoami-rajat | if you are planning to propose a driver or have already proposed it, please add it to the above etherpad ^ | 14:11 |
| whoami-rajat | on a related note, it's a good time to propose stable releases | 14:13 |
| whoami-rajat | jbernard doesn't seem to be around at this time but i can have a chat with him later | 14:13 |
| whoami-rajat | #link https://lists.openstack.org/pipermail/openstack-discuss/2023-June/034062.html | 14:13 |
| whoami-rajat | Thierry mentioned a script that can provide list of unreleased changes | 14:14 |
| whoami-rajat | tools/list_stable_unreleased_changes.sh | 14:14 |
| whoami-rajat | that's all the announcements i had | 14:16 |
| whoami-rajat | let's move to topics | 14:16 |
| whoami-rajat | #topic Vancouver 2023 Summit/PTG/Forum report | 14:17 |
| whoami-rajat | #link https://etherpad.opendev.org/p/cinder-vancouver-2023-followup | 14:17 |
| whoami-rajat | rosmaita wrote a great summary of the PTG | 14:18 |
| whoami-rajat | for people who are not aware, we had in-person PTG in Vancouver from 13-15 June and some of the team members attended | 14:18 |
| whoami-rajat | you can read through the summary but I have created a summary of the summary | 14:18 |
| whoami-rajat | i.e. just the highlights of what rosmaita mentioned (according to me) | 14:19 |
| whoami-rajat | TC & Community Leaders Interaction | 14:19 |
| whoami-rajat | we need to better communicate the available job troubleshooting tools that we have available | 14:19 |
| whoami-rajat | services are encouraged to add sqlalchemy 2.0 jobs (as non-voting) to catch problems (and then fix them) | 14:19 |
| whoami-rajat | S-RBAC Operator Feedback | 14:19 |
| whoami-rajat | we're sticking with only project scope for now | 14:19 |
| whoami-rajat | operators would like some more default personas, but we need to get the current goal completed before thinking about these | 14:19 |
| whoami-rajat | global reader | 14:19 |
| whoami-rajat | L2-support-admin | 14:19 |
| whoami-rajat | domain scope support | 14:19 |
| whoami-rajat | Managing OSC and SDK as multi-project deliverables | 14:20 |
| whoami-rajat | cinder-core will be added to osc-service-core and sdk-service-core as +2 (and not +W) | 14:20 |
| whoami-rajat | this is really a good news, we will get to have faster code merges in osc and sdk ^ | 14:20 |
| whoami-rajat | The OpenStack Block Storage service ... how are we doing? | 14:20 |
| whoami-rajat | operators would like multiple backup backends | 14:20 |
| whoami-rajat | How do we end the Extended Maintenance "experiment"? | 14:21 |
| whoami-rajat | There was agreement that the name "extended maintenance" is not accurate, and we need to come up with something different/update the docs | 14:21 |
| whoami-rajat | Several operators argued that keeping the branches available (even if CVE fixes are not merged into them) is useful for collaboration | 14:21 |
| enriquetaso | ++ | 14:22 |
| whoami-rajat | though we didn't have any opposition on the ML, some operators seems to have issues with EOLing the EM branches ^ | 14:22 |
| IPO | + | 14:23 |
| enriquetaso | ++ to +2 to osc and sdk | 14:23 |
| whoami-rajat | yeah, we have been trying to get more involvement in those projects, good to see progress being made there | 14:24 |
| whoami-rajat | i would still recommend going through Brian's summary but hopefully the information was helpful | 14:24 |
| enriquetaso | i will, thanks rajat | 14:25 |
| whoami-rajat | thanks enriquetaso | 14:26 |
| whoami-rajat | that was all for today | 14:26 |
| whoami-rajat | let's move to open discussion | 14:26 |
| whoami-rajat | #topic open discussion | 14:26 |
| zaitcev | Is there a LP bug for multiple backup back-ends? I am not sure if I saw one or not. | 14:27 |
| enriquetaso | are you talking about https://review.opendev.org/c/openstack/cinder-specs/+/868761 zaitcev ? | 14:28 |
| whoami-rajat | enriquetaso, i think that is different | 14:29 |
| whoami-rajat | we are referring to being able to configure multiple backup backends | 14:29 |
| whoami-rajat | like we do for volume backends | 14:29 |
| enriquetaso | oh sorry | 14:29 |
| zaitcev | enriquetaso: no, unless having multiple back-ends requires the separate status. I don't think it does. | 14:30 |
| whoami-rajat | the spec you referred is for allowing other operations like live migration along with backup | 14:30 |
| whoami-rajat | zaitcev, i remember we had discussions about it in the past, and maybe an old spec for it | 14:30 |
| whoami-rajat | let me look | 14:30 |
| zaitcev | I seem to remember some kind of spec for the syntax... Like [backup-1] or something? | 14:30 |
| whoami-rajat | zaitcev, https://review.opendev.org/c/openstack/cinder-specs/+/712301 | 14:31 |
| IPO | I'd like to sort out with Active/Active cinder cluster and allocated_capacity_gb - https://bugs.launchpad.net/cinder/+bug/1927186 - it there is some time and persons for it | 14:31 |
| zaitcev | whoami-rajat: perfect, thanks. I got that. So, do we have a bug in LaunchPad to track the progress and issues of this? | 14:32 |
| enriquetaso | eharney, found a issue that may be related with configure multiple backup backends with ceph/rbd backup driver. Currently it's possible to select a diff backend/pool/container using the `--container` argument when creating the backup | 14:34 |
| enriquetaso | #link https://bugs.launchpad.net/cinder/+bug/2024484 | 14:35 |
| eharney | hmm | 14:37 |
| eharney | looks like a good thing to fix | 14:37 |
| whoami-rajat | if that's all for the discussion, we can end the meeting early today | 14:42 |
| IPO | I'd like to sort out with Active/Active cinder cluster and allocated_capacity_gb - https://bugs.launchpad.net/cinder/+bug/1927186 - it there is some time and persons for it | 14:42 |
| whoami-rajat | IPO, i think geguileo might be able to help in Active Active related things, though not sure if he is around since i don't see him in the meeting | 14:43 |
| geguileo | whoami-rajat: I'm around | 14:44 |
| IPO | :) | 14:45 |
| whoami-rajat | great! | 14:45 |
| eharney | didn't hemna do some work that improved capacity tracking w/ multiple services running? | 14:45 |
| geguileo | eharney: I believe his work was around properly counting in all the missing cases | 14:45 |
| geguileo | The problem with A/A is a different pain :'-( | 14:46 |
| eharney | ah | 14:46 |
| geguileo | Basically all schedulers have different accounting, and also all the different volume services will have different numbers | 14:46 |
| geguileo | So it's a literal mess | 14:46 |
| IPO | geguileo: So you confirm that it is the bug and there is no some missconfuguratio, etc... | 14:48 |
| whoami-rajat | geguileo, but i think IPO tried with a single scheduler but still sees issues with counting | 14:48 |
| whoami-rajat | s/counting/allocated_capacity_gb | 14:48 |
| IPO | Thx, rajat. Single scheduler, multiple cinder-volumes in cluster | 14:48 |
| geguileo | whoami-rajat: yeah, because in A/A you also have different values on the different cinder-volume nodes | 14:48 |
| geguileo | The problem is that our current code does absolute accounting everywhere | 14:49 |
| geguileo | So everyone thinks their value is "the right one" | 14:49 |
| geguileo | It's a mess | 14:49 |
| whoami-rajat | geguileo, hmm, i thought c-vol only sends the capabilities to the scheduler and scheduler caches it | 14:49 |
| whoami-rajat | i could be wrong though | 14:49 |
| geguileo | cinder-volume also changes those values during some operations | 14:49 |
| geguileo | iirc that's where hemna did changes | 14:50 |
| whoami-rajat | it's during host initialization IIRC | 14:50 |
| IPO | so looks like it is real bug... As I wrote, may be usage of memcached will help | 14:50 |
| whoami-rajat | but IPO says the values get corrected during that but again it becomes inconsistent after a while | 14:50 |
| IPO | Yes, it corrected after restart of all cinder volume | 14:51 |
| IPO | and than after time it go back to incorrec (even negative) values | 14:51 |
| whoami-rajat | yeah so I'm not sure apart from host initialization, we change the values anywhere else | 14:52 |
| whoami-rajat | in c-vol i mean | 14:53 |
| IPO | Instad of listening for RPC notifications to correct allocated_capacity_gb for each cinder volume and use memcached to share this value I think there is one way to correct it | 14:53 |
| IPO | less complicated... We can add one more pereodic task for recalculation of allocated_capacity_gb | 14:54 |
| geguileo | IPO: the problem with that approach is that we'd be adding a new service dependency | 14:54 |
| IPO | I even create POC with chunks of volume init code | 14:55 |
| geguileo | IPO does you POC make atomic modifications when cinder-volume or scheduler make changes to those values? | 14:56 |
| IPO | No ofcourse :) no locks and etc | 14:57 |
| IPO | But it looks like better when to schedule cinder-volume service restart on pereodic basis | 14:58 |
| geguileo | IPO I think the whole "stats" model needs a rethink | 14:59 |
| IPO | ++ | 14:59 |
| IPO | But we need to live somehow till bright future will come | 15:00 |
| whoami-rajat | we're out of time | 15:00 |
| whoami-rajat | we can continue discussion in #openstack-cinder | 15:00 |
| whoami-rajat | after the BS meeting ofcourse | 15:00 |
| whoami-rajat | thanks everyone for joining | 15:00 |
