Hey Jim, Thank you for the reply! I was looking at this untargeted specs page for the project. http://specs.openstack.org/openstack/glance-specs/specs/untargeted/glance/d… It is stated in this page that this project is currently unassigned. I will start working on this spec. I will begin by studying Glance and start making smaller contributions to it for now. I need all the help I can get! I am very passionate about OpenStack and it's services! I will keep in touch with you and the developers through this mailing list and the IRC channel.

You cannot publish over the previously published versions: 0.0.4. : karma-subunit-reporter History here is that the tag in the git repo was incorrectly named (v0.0.4) last time the release was manually uploaded to npm (as 0.0.4). Since this is a re-release of the tag with correct name (0.0.4), the fact that the publication is failing (and announcement is skipped) is probably a good thing. -- Thierry Carrez (ttx)

[placement] How do we migrate DB manipulating data?
by TETSURO NAKAMURA 21 Dec '18

21 Dec '18

Hi, I'd like to discuss how we can have DB upgrade migration method (with data manipulation) in placement. --- BackGround ========== https://bugs.launchpad.net/nova/+bug/1803925 * In Rocky, to have nested resource provider feature, we expanded the DB to have root provider id column. * The root provider id shouldn't be None and for root providers it should be the same value of its resource provider id. * In Rocky, the code is build in a backward compatible way doing online migration. * For each request of listing/showing resource providers, we look the root provider id and if it is stale and empty, we assume the resource provider is a root and set the same value as resource provider id. * Those providers that are not called in the Rocky cycle will still have an empty value for the root provider id. * In Stein or later, we want a way to be sure that all the root provider id contains some non-None value. * This is because we have a lot of TODOs in code which we want to clean up once we are sure all the root provider ids have non-None value in the DB. * In Stein, we are already ready use alembic to manage DB schema changes in placement. Question ======== How should we copy the resource provider id to root provider id if the root provider id is None? Options ======= 1. Do it in the alembic script in the same way as the schema expansion * This is done in the https://review.openstack.org/#/c/619126/ and brought several concerns. * We don't want the data manipulation migration to be inter-mixed with schema changes. * For cases skipping one release in an FFU fashion, there would be a lot of rows to be changed. 2. Have two stable version branches for alembic to separate schema changes and data manipulation * Neutron has been managing two branches in alembic already. * https://specs.openstack.org/openstack/neutron-specs/specs/liberty/online-sc… * Developers would specify on which branch to have a new version via some a new CLI something like; `placement-db-manage revision -m "description of revision" (--schema-change|--data-manipulate)` * We should be careful for the dependency management across the two branches. * https://alembic.sqlalchemy.org/en/latest/branches.html 3. Bring the online-migration batch CLI command * Follow the traditional way to manage DB data in Nova * `placement-manage db online-data-migration [--max-count]` * I'm looking into this in https://review.openstack.org/#/c/624942/. 4. Any other ideas? --- Since it looks like it's going to have an impact both on operators who upgrade and developers who add new features in placement, it is nice to seek more ideas and to have a consensus before we go further.

[tripleo][ci] Reducing merge time by moving nv job to experimental
by Felix Enrique Llorente Pastora 21 Dec '18

21 Dec '18

Hello, To reduce merge time, would be nice from a review to go from check pipeline to gate pipeline without waiting for non-voting jobs, one way to do that is changing non-voting jobs at different pipelien like experimental one, so we have their result but don't wait for them to change to gate pipepeline. -- Quique Llorente Openstack TripleO CI

[glance][dev] Regarding "Eliminate Redundant Downloads of Uncached Images" project
by Vedartham Bharath 20 Dec '18

20 Dec '18

Hi all, I am very interested in working on one of the untargeted approved specifications in Glance. It is titled "Eliminate Redundant Downloads of Uncached Images". I have noticed that it is currently unassigned. My experience with OpenStack: I have setup Devstack. I have worked extensively on Swift as part of a research project. I have set up Swift All in One multiple times. I have also set up a multi-server installation of Swift. I have studied the codebase of Swift and added my own features for my project. I am willing to dedicate myself to study glance and work on this project. I would love to know if it is up for grabs! Bharath

[dev][tc] Feedback on adding the 'API Version Based Feature Discovery' in OpenStack Technical Vision
by Ghanshyam Mann 20 Dec '18

20 Dec '18

Hello everyone, As you know, last month we had merged the very well written technical vision doc by Zane[1]. To extend it further, I am proposing a section/item to add about API-Version based feature discovery [1]. Each OpenStack Service should provide a mechanism to know the supported min and max API version in a cloud which further will help to discover the enhanced or new features. Also, a user should be able to query detailed information about features and enhancement per version. Patch 621516 is documenting this API version based discovery idea in vision doc, and I am looking forward for more feedback/opinion on this.

Backporting networking-ansible to Queens
by Dan Radez 20 Dec '18

20 Dec '18

We have requested to add ansible-runner and update the version of python-pexpect from 4.3 to 4.5 in the openstack-requirements repository. https://review.openstack.org/#/c/624048 This is in effort to enable the networking-ansible ML2 driver in Queens. It was developed as part of the Rocky development cycle. We understood that this is outside the structure of standard practice and would like to request an exception for this change in light of it's low risk. We have customers that are asking for this ML2 driver to be enabled in our product that is based on Queens. We would like to push these changes to upstream first. This exposes the community to this code and prevents the need to carry patches downstream. This ML2 driver is an add on feature that should carry little to no technical debt for the stable/Queens code base. Python-pexpect need to be updated and we will update Triple-o to enable it to install and configure the new driver. Otherwise the backport consists of adding the ansible-runner dependency and packaging the code for the networking-ansible ML2 driver. End users are impacted only when they choose to install the feature and enable it. Thank you for your consideration, Dan Radez

[cinder][ops][docs] policy configuration howto
by Brian Rosmaita 20 Dec '18

20 Dec '18

At last week's cinder meeting (5 December) we had a discussion about policy checks at the database layer. While these checks seem to make it difficult to perform some policy configurations, there are too many of them to simply remove them without impacting stability given our current test coverage (at least that's my feeling). Additionally, it's possible to handle the proposed use case (a read-only administrator) without making any code changes. So we decided to fix this issue by documenting how this could work. I've got a patch up for the documentation. I've flagged this email for cinder people to read for accuracy, operators to read to make sure the instructions are clear and detailed, and docs people to read for felicity of expression. Please leave comments on the patch: https://review.openstack.org/#/c/624424/ cheers, brian

[Cinder] Image Name of all Instances does not show up
by Minjun Hong 20 Dec '18

20 Dec '18

Hi. After I installed Cinder, 'Image Name' of the created instances does not show up on horizon. When I created instances without Cinder, 'Image Name' of all instances was filled with the name of image which is used for creating the instance on horizon, like this link (https://imgur.com/0Habda7) Actually, although this does not cause any critical incorrect operation, it can make the users who use the Openstack system confused what image is used for the instances. That's why I need to resolve this issue. How can I fill 'Image Name' column with the name of the image ? Thanks! Regards,

Re: Failed live migration and duplicate attachments

How would you recommend addressing the duplicate attachments? There doesn't seem to be any adverse effect of them being there, but I cannot detach them because they are root volumes.
