[k8s] [manila] Manila CSI driver plan
by Tom Barron 21 Nov '18

21 Nov '18

[Robert Vasek, Red Hat colleagues working in this space: please correct any mis-understandings or omissions below] At the Berlin Summit SIG-K8s Working session [1] [2], we agreed to follow up with a note to the larger community summarizing our plan to enable Manila as RWX storage provider for k8s and other container orchestrators. Here it is :) Today there are kubernetes external service providers [3] [4] for Manila with NFS protocol back ends, as well as a way to use an external service provider on the master host in combination with a CSI CephFS node-host plugin [5]. We propose to target an end-to-end, multi-protocol Manila CSI plugin -- aiming at CSI 1.0, which should get support in container orchestrators early in 2019. Converging on CSI will: * provide support for multiple Container Orchestrators, not just k8s * de-couple storage plugin development from k8s life-cycle going forwards * unify development efforts and distributions and set clear expectations for operators and deployers Since manila needs to support multiple file system protocols such as CephFS native and NFS, we propose that work align to the multiplexing CSI architecture outlined here [6]. High level work plan: * Write master host multiplexing controller and node proxy plugins. * Use CephFS node-only plugin from [5] * Write NFS node-only plugin NFS and CephFS are immediate priorities - other file system protocols supported by manila can be added over time if there is interest. -- Tom Barron (irc: tbarron) [1] https://www.openstack.org/summit/berlin-2018/summit-schedule/events/22752/s… [2] https://etherpad.openstack.org/p/sig-k8s-2018-berlin-summit [3] https://github.com/kubernetes-incubator/external-storage [4] https://github.com/kubernetes/cloud-provider-openstack [5] https://www.openstack.org/summit/berlin-2018/summit-schedule/events/21997/d… [6] https://github.com/container-storage-interface/spec/issues/263#issuecomment…

[tc][python3] next steps for resolution on tracking python 3 releases
by Doug Hellmann 21 Nov '18

21 Nov '18

We currently have 3 changes up for review related to our python 3 testing plans. I think if we line them up in a series it will be clearer how they relate to each other and how we can move ahead with them as a set. I think first we need Zane's resolution [1], since that describes the process we want to use. We're dealing with some final wording questions there, but I think it's very close to ready as it is now. Next, we want Sean's patch that sets the versions we want tested for Stein [2]. Zane proposed that we should have goal champions designated in that change, so we could find someone to do that or we could go ahead and take it as-is and add that information later. Finally, we need a variation of Jeremy's patch that makes the PTI less detailed [3]. One update we could make there is to describe how to find (or link to) the information in the previous patch instead of using any specific versions at all. Thoughts?

OpenStack Summit Berlin Presentation Videos & Slides
by Jimmy McArthur 21 Nov '18

21 Nov '18

Thank you to everyone for a great OpenStack Summit last week in Berlin! As you know, there were hundreds of breakout sessions to catch last week. Videos from the keynote sessions are currently available here [1], and our team is working to get the other breakout session videos loaded as quickly as possible. We're currently expecting all videos to be posted by mid-December, and if we get them up sooner, I'll update this thread. In the meantime, you can watch the keynotes videos [2] and watch this page [3] for updates. Please also note that we sent out a link to all presenters to upload their slides. As they are uploaded, they can be found on the details page for each presentation on the Berlin Summit Schedule [3] (along with videos, as they are processed). Cheers, Jimmy [1] https://www.openstack.org/videos/summits/berlin-2018 [2] https://www.openstack.org/videos/ [3] https://www.openstack.org/summit/berlin-2018/summit-schedule/

Let's use [dev] for development discussions
by Thierry Carrez 21 Nov '18

21 Nov '18

Hi openstack-discuss, As part of the ML merge, we introduced a number of subject prefixes to help subscribers filter discussions. The most important ones are to use: [dev] For discussions that are purely development-oriented [ops] For discussions that are purely operations-oriented Of course (as we have realized with the amount of cross-posted topics), most discussions benefit from input from all our contributors, whether they come from an development or an operational background. For those, there is no need to apply [dev] and/or [ops] prefixes, just try to be informative by adding the project name, team name or other information instead. You can ping specific populations by adding: [tc] Discussions of interest for TC members [uc] Discussions of interest for UC members [ptl] Discussions of interest for all PTLs [release] Release team, release liaisons and PTLs You can also specifically use (with care): [all] For discussions that should really be of interest to EVERYONE See (and add!) other common subject prefixes at: https://etherpad.openstack.org/p/common-openstack-ml-topics Thanks for your help in making this common list more navigable. -- Thierry Carrez (ttx)

[infra] [zuul] [placement] Minimizing size/time of test node
by Chris Dent 21 Nov '18

21 Nov '18

I have a work in progress to run a little job in placement that gathers very simple performance numbers on some queries. This is being done as a sort of sanity check. As with many such things it is a bit rough around the edges and I'd like to make it smoother in a variety of ways. The WIP is at https://review.openstack.org/#/c/602484/ One of the ways I'd like to change it is to not rely on devstack. I need only mysql, uwsgi, python and the current revision of placement on the node. The current job uses devstack-minimal as its base but that's overkill and slow. What is the correct base job to use which, as long as I put the files in the right place, will gather the logs I want? Thanks. -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent tw: @anticdent

[openstack-dev] VM stalls with the console log "Exiting boot services and installing virtual address map"
by Srikanth Kumar Lingala 21 Nov '18

21 Nov '18

Hi, I am working with OpenStack stable/pike release in Ubuntu 18.04. When I am trying to spawn VM, which is worked in the earlier OpenStack releases, VM is stalled with the following log in the VM console logs: EFI stub: Booting Linux Kernel... EFI stub: Generating empty DTB EFI stub: Exiting boot services and installing virtual address map... I am observing that VM is in Running status, without any error logs. And, VM is booting with UEFI support. But, I am not able to get VM Console. Earlier I didn't observe this. How can I disable UEFI support, while spawning VM's in OpenStack Nova-Compute. My Libvirt version is 4.0.0. Can someone help me to fix the issue. Regards, Srikanth. -- ---- Srikanth. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: OpenStack-dev-request@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
