[manila] Remote-only PTG poll
by Goutham Pacha Ravi 05 Dec '19

05 Dec '19

Hey Zorillas* and interested Stackers, (* manila contributors in the wild) A part of our community will be attending the Summit+Forum+PTG in Shanghai in a couple of weeks. However, we haven't figured out a way to enable remote participation during our PTG (Wednesday, 6th Nov 2019 between 9:00 AM and 4:30 PM) there. So, as discussed during our weekly meeting, I'd like to take a poll of when you would like to gather for a remote PTG that would supplement the gathering in Shanghai. Please take this poll and indicate your availability: https://xoyondo.com/dp/qQbsoHtNhi4DCki The prospective date for this meeting is between 2nd Dec and 13th Dec (Ussuri-1 Milestone is on 12th Dec). The meeting time will be 15:00 UTC to 22:00 UTC. This time may not work for our contributors in the Far East (APAC), but I'm hoping we'll address them primarily at the Shanghai get together, and relay their thoughts here. We will also be recording the entire meeting and will share notes on these lists. Thanks, Goutham

[oslo] Adoption of microversion-parse
by Thierry Carrez 28 Nov '19

28 Nov '19

Hi Osloites, A recent review of the OpenStack namespace yielded a library that no project team owns, and yet is specific to openstack and present in global-requirements: https://opendev.org/openstack/microversion-parse Ideally it should be adopted by one of our project teams. After discussing it with cdent, and since it is openstack-specific and depended on by most openstack projects, it feels like Oslo would be a good home for it. It would follow an "independent" release model and I don't think it would trigger much updates or maintenance. I can post patches to make it happen if you confirm you're OK to host it. Just keep me posted :) Cheers, -- Thierry Carrez (ttx)

Re: [ironic]: Timeout reached while waiting for callback for node
by fsbiz＠yahoo.com 26 Nov '19

Thanks Julia. In addition to what you mentioned this particular issue seems to have cropped up when we added 100 more baremetal nodes. I've also narrowed down the issue (TFTP timeouts) when 3-4 baremetal nodes are in "deploy" state and downloading the OS via iSCSI. Each iSCSI transfer takes about 6 Gbps and thus with four transfers we are over our 20Gbps capacity of the leaf-spine links. We are slowly migrating to iPXE so it should help. That being said is there a document on large scale ironic design architectures?We are looking into a DC design (primarily for baremetals) for upto 2500 nodes. thanks,Fred, On Wednesday, October 23, 2019, 03:19:41 PM PDT, Julia Kreger <juliaashleykreger(a)gmail.com> wrote: Greetings Fred!

Sadly this is one of those things that comes with using TFTP. Issues like this is why the community tends to recommend using ipxe.efi to chainload as you can perform transport over TCP as opposed to UDP where in something might happen mid-transport. tftpd shows ramdisk_deployed completed. Then, it reports that the client timed out. Grub does tend to be very abrupt and not wrap up very final actions. I suspect it may just never be sending the ack back and the transfer may be completing. I'm afraid this is one of those things you really need to see on the console what is going on. My guess would be that your deploy_ramdisk lost a packet in transfer or that it was corrupted in transport. It would be interesting to know if the network card stack is performing checksum validation, but for IPv4 it is optional. [trim] This has me stumped here. This exact failure seems to be happening 3 to 4 times a week on different nodes.Any pointers appreciated. thanks,Fred.

[all][tc] Planning for dropping the Python2 support in OpenStack
by Ghanshyam Mann 21 Nov '19

21 Nov '19

Hello Everyone, Python 2.7 is going to retire in Jan 2020 [1] and we planned to drop the python 2 support from OpenStack during the start of the Ussuri cycle[2]. Time has come now to start the planning on dropping the Python2. It needs to be coordinated among various Projects, libraries, vendors driver, third party CI and testing frameworks. * Preparation for the Plan & Schedule: Etherpad: https://etherpad.openstack.org/p/drop-python2-support We discussed it in TC to come up with the plan, execute it smoothly and avoid breaking any dependent projects. I have prepared an etherpad[3](mentioned above also) to capture all the points related to this topic and most importantly the draft schedule about who can drop the support and when. The schedule is in the draft state and not final yet. The most important points are if you are dropping the support then all your consumers (OpenStack Projects, Vendors drivers etc) are ready for that. For example, oslo, os-bricks, client lib, testing framework projects will keep the python2 support until we make sure all the consumers of those projects do not require py2 support. If anyone require then how long they can support py2. These libraries, testing frameworks will be the last one to drop py2. We have planned to have a dedicated discussion in TC office hours on the 24th Thursday #openstack-tc channel. We will discuss what all need to be done and the schedules. You do not have to drop it immediately and keep eyes on this ML thread till we get the consensus on the community-level plan and schedule. Meanwhile, you can always start pre-planning for your projects, for example, stephenfin has started for Nova[4] to migrate the third party CI etc. Cinder has coordinated with all vendor drivers & their CI to migrate from py2 to py3. * Projects want to keep the py2 support? There is no mandate that projects have to drop the py2 support right now. If you want to keep the support then key things to discuss are what all you need and does all your dependent projects/libs provide the support of py2. This is something needs to be discussed case by case. If any project wants to keep the support, add that in the etherpad with a brief reason which will be helpful to discuss the need and feasibility. Feel free to provide feedback or add the missing point on the etherpad. Do not forget to attend the 24th Oct 2019, TC office hour on Thursday at 1500 UTC in #openstack-tc.

[ptg] Auto-generated etherpad links !
by Thierry Carrez 13 Nov '19

13 Nov '19

Hi everyone, The PTGbot grew a new feature over the summer. It now dynamically generates the list of PTG track etherpads. You can find that list at: http://ptg.openstack.org/etherpads.html If you haven't created your etherpad already, just follow the link there to create your etherpad. If you have created your track etherpad already under a different name, you can overload the automatically-generated name using the PTGbot. Just join the #openstack-ptg channel and (as a Freenode authenticated user) send the following command: #TRACKNAME etherpad <URL for your etherpad> Example: #keystone etherpad https://etherpad.openstack.org/p/awesome-keystone-pad That will update the link on that page automatically. Hoping to see you in Shanghai! -- Thierry Carrez (ttx)

[kuryr] [tc] kuryr project mission
by Michał Dulko 13 Nov '19

13 Nov '19

Hi, It's been more than a year after fuxi [1] and fuxi-kubernetes [2] were declared as retired. First one was supposed to integrate Docker with Cinder and Manila. The second was aiming to do the same with Kubernetes. I'm not really sure how to serve the first use case, but it seems like there are some alternatives [3], [4]. fuxi-kubernetes use case is now served by Cloud Provider OpenStack in Cinder [5] and Manila [6] CSI plugins, which seem like a much better fit. Currently the only maintained deliverables in kuryr project are kuryr, kuryr-libnetwork and kuryr-kubernetes. All of them are related to networking. Given that I'd like to propose rephrasing Kuryr mission statement from: > Bridge between container framework networking and storage models > to OpenStack networking and storage abstractions. to > Bridge between container framework networking models > to OpenStack networking abstractions. effectively getting storage out of project scope. Are there any thoughts or objections? Maybe someone sees a better phrasing? Thanks, Michał [1] https://opendev.org/openstack/fuxi [2] https://opendev.org/openstack/fuxi-kubernetes [3] https://rexray.readthedocs.io/en/stable/user-guide/schedulers/docker/plug-i… [4] https://github.com/j-griffith/cinder-docker-driver [5] https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/usi… [6] https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/usi…

[tc][horizon][all] Horizon plugins maintenance
by Ivan Kolodyazhny 13 Nov '19

13 Nov '19

Hi team, As you may know, we've got a pretty big list of Horizon Plugins [1]. Unfortunately, not all of them are in active development due to the lack of resources in projects teams. As a Horizon team, we understand all the reasons, and we're doing our best to help other teams to maintain plugins. That's why we're proposing our help to maintain horizon plugins. We raised this topic during the last Horizon weekly meeting [2] and we'll have some discussion during the PTG [3] too. There are a lot of Horizon changes which affect plugins and horizon team is ready to help: - new Django versions - dependencies updates - Horizon API changes - etc. To get faster fixes in, it would be good to have +2 permissions for the horizon-core team for each plugin. We helped Heat team during the last cycle adding horizon-core to the heat-dashboard-core team. Also, we've got +2 on other plugins via global project config [4] and via Gerrit configuration for (neutron-*aas-dashboard, tuskar-ui). Vitrage PTL agreed to do the same for vitrage-dashboard during the last meeting [5]. Of course, it's up to each project to maintain horizon plugins and it's responsibilities but I would like to raise this topic to the TC too. I really sure, that it will speed up some critical fixes for Horizon plugins and makes users and operators experience better.
