Service Coordinator Nominations
by Clark Boylan 30 Jan '21

30 Jan '21

Hello everyone, It has been pointed out that in our governance document we stated we would elect a service coordinator every 6 months. I filled this role at the beginning of May 2020 which means we are overdue for a new election. The beginning of the year is always a bit slow so I figure we can give folks until January 31st at 23:59UTC to nominate themselves. Then if we need an election we can do that during the week from February 1st to February 8 at 23:59UTC. I've now been in this role (either as Service Coordinator or Infra PTL) a while. I think it would excellent to rotate in some new eyeballs and perspectives if possible. If you have interest but also have questions feel free to reach out. In order to avoid this slipping by in the future I'm going to go ahead and write down the dates for the next nomination period and election now: * Nominations July 12, 20201 - August 1, 2021 at 23:59 UTC * Election if necessary August 2 - August 9, 2021 at 23:59 UTC I think I got the math right. If I've got it wrong or you have other concerns feel free to bring them up on this thread and we can sort things out. I'm trying to balance giving people enough time to show interest at the beginning of the year while also not letting this languish for longer than it needs to. Then doing math for what 6 months from now will look like. Clark

Fwd: [All][StoryBoard] Angular.js Alternatives
by Kendall Nelson 26 Jan '21

26 Jan '21

Hello Everyone! The StoryBoard team is looking at alternatives to Angular.js since its going end of life. After some research, we've boiled all the options down to two possibilities: Vue.js or React.js I am diving more deeply into researching those two options this week, but any opinions or feedback on your experiences with either of them would be helpful! Here is the etherpad with our research so far[3]. Feel free to add opinions there or in response to this thread! -Kendall Nelson (diablo_rojo) & The StoryBoard Team [1] https://vuejs.org/ [2] https://reactjs.org/ [3] https://etherpad.opendev.org/p/replace-angularjs-storyboard-research

Requesting help with OpenStack configuration files
by Bessghaier, Narjes 19 Jan '21

19 Jan '21

Dear OpenStack team, I’m a Ph.D. student in software engineering at the ETS Montreal, University of Quebec working on the quality and configuration of web-based software systems. I’m particularly interested in analyzing configuration files from different OpenStack files. One of the main challenges I am currently facing is the proper identification of configuration files. I’m mostly confused between the python files used for production and the python files used for configuration. I am kindly requesting your precious help with the following questions: 1- How to distinguish between python files used for configuration and python files used for production? It will be very helpful if there are some configuration-based patterns (eg, textual patterns or expressions) that we can find in python files to help us distinguish between source code and configuration files? 2- Certain python files use the oslo_config to access and define configuration options. Could "all" these python files be considered as configuration files? For example, the following python file of the keystone project: keystone/keystone/conf/auth.py, is it considered a source code or a configuration file? 3- Why are there different source code and configuration repositories for OpenStack projects (eg, nova and puppet-nova)? For instance, does the OpenStack-nova service have some configuration files in its repository and have the puppet-nova as a separate configuration repository as well? Thank you very much in advance for your time and your help! Kind regards, Narjes Bessghaier Narjes Bessghaier Ph.D student in Software Engineering École de Technologie Supérieure (ETS)| University of Quebec Montreal, Canada narjes.bessghaier.1(a)ens.etsmtl.ca<mailto:yasmine.makroum.1@ens.etsmtl.ca>

OpenAFS timestamp rollover issues, discussion and plan
by Ian Wienand 15 Jan '21

15 Jan '21

Hello, We were made aware of an issue relating to handling of a timestamp rollover affecting OpenAFS deployments [1] that in the worst case results in inability of the client and server to communicate. From the OpenAFS 1.8.7 release: It fixes a critical issue in the generation of Rx connection IDs that prevent Rx clients started after 14 Jan 2021 08:25:36 AM UTC from being able to successfully make connections. In addition to cache managers and client utilities, fileservers and database servers are also affected, since they initiate connections to (other) database servers during their normal operation. The issue occurs only at startup, while generating the initial connection ID, so cache managers or servers that were already running at the time in question will not be affected until they restart. The full extent of the issues for our particular circumstances is still somewhat unclear. We run a heterogeneous deployment with all clients under our control using 1.8.6 release, but all servers running 1.6 era packages from Ubuntu Xenial. My current understanding is that since we started our servers and clients before the problem time, we are currently unaffected. When we restart our servers, due to differences in the code with our 1.6 versions, the bug will manifest more as periodic/random-ish I/O failures rather than a complete inability to communicate. We have rebuilt our openafs packages with the required fixes and deployed these to all clients under our control. Thus if any client restarts for whatever reason, they will at least be using fixed code. Some clients we have restarted just to ensure sanity of the new version against the existing severs (so far seems good). All clients have been checked for deployment of these new packages. We do not expect issues, but will monitor this situation. This leaves us with the server side. We have been told there are no fixes for the 1.6 servers planned. We do not have a wonderful answer here, unfortunately. We have planned to move our AFS infrastructure off the Xenial hosts it runs on for some time. These servers are all deployed with legacy puppet, something none of us want to spend significant time hacking on. There is also the small matter that 1.6 to 1.8 upgrades are not terribly well documented, to say the least. While we don't intend on restarting the servers, from time to time the cloud provider needs to migrate things or has other issues that affect uptime; we can't predict this other than it will happen, eventually. It seems our best option here is to take some down-time of the AFS services and perform a manual, in-place upgrade of the existing servers to 1.8 code. We will freeze these from ongoing automated config managment (puppet). This will allow us to deploy and evaluate 1.8 servers and keep with the principle of "change one thing at a time". Once we are in a steady state, we should have enough redundancy that we can replace the servers one-at-a-time with no, or very little, downtime. This gives us time to write, test and review Ansible based deployment as usual. When we do switch in new Focal based servers, we have the advantage we are not also trying to change the AFS version too. In some ways, it works out well (something about lemons and lemonade). We usually try to have a rollback plan with any upgrades. Since 1.6 is not getting updates, and as far as I know we still do not have the technology to move reality backwards in the time continum before the problem rollover time (if I do figure out time travel, I will be sure to pre-respond to this message that it can be ignored) our revert plans seem limited. However, we will be no worse off than if the servers decided to reboot themselves now. In it's defence, this is not new code; 1.8.0 came out early 2018 and we have been using 1.8 clients since we started integrating arm64. The queues are very deep at the moment, so we'd obviously like to minimise downtime. I'd suggest that I could start looking at this around 2021-01-17 21:00UTC, following the plan layed out in [2], which interested parties should definitely review. This should hopefully be a quiet time, and give us a decent runway if we do hit issues. -i [1] https://lists.openafs.org/pipermail/openafs-info/2021-January/043013.html [2] https://etherpad.opendev.org/p/infra-openafs-1.8
