May 2021 - Dev - lists.ceph.io

by David Galloway

After getting CentOS 8 working, I spent Friday adding the latest CentOS 9 Stream compose to the Sepia lab. Same deal with 8. We have FOG images for smithi and gibba. teuthology-lock --lock-many 1 -m smithi --os-type centos --os-version 9.stream Some important differences: - Missing Packages: podman-docker, ant, libev-devel, python3-nose, python3-virtualenv, dbench, iozone - No lab-extras - No EPEL9 Not sure how useful it'll be but have fun. -- David Galloway Senior Systems Administrator Ceph Engineering

Ceph Leadership Team meeting 2021-05-12

by Ilya Dryomov

Hello, Highlights from this week: - release process improvements and coordination - currently ad-hoc email threads and #ceph-backports IRC channel - works well for David, but we did have a couple of instances of false "good to go" where some fixes intended for release were not in yet - want to give a heads up that the release is happening sooner - Yuri will email dev(a)ceph.io a week before locking the branch and starting validation - the team will keep track of upcoming releases in the CLT pad [1] - urgent release-related queries or concerns should go to clt(a)ceph.io - issues with generating release emails and blog posts - cephadm backports are done in batches, individual PRs are not listed - generated html requires manual edits - should be resolved with moving off WordPress - being able to release from a hotfix branch to avoid branch juggling - remains on David's list, Loic is interested too - upcoming releases - 16.2.4, 15.2.12 and 14.2.21 hotfix releases (rgw and dashboard) - also https://tracker.ceph.com/issues/50347 for 16.2.4? - 15.2.13 release to be frozen in two weeks - final 14.2.z release in June, nautilus is almost EOL! - scrub of Ceph project on the tracker - almost complete, what is left are mostly doc tickets and build/packaging related issues for various distros - also issues that turn up in testing where component is not clear - need to triage these during regular bug scrubs - Ceph Month June event - include 20-30 minutes updates from component leads - CFP closes today, schedule to be posted on May 19th - new ceph.com site - static markdown (yay!) - need octopus-themed artwork, don't want generic stock imagery [1] https://pad.ceph.com/p/clt-weekly-minutes Thanks, Ilya

nautilus, octopus and pacific branches restored

by Ilya Dryomov

Hi everyone, You may have noticed some unusual activity in the backport PRs in the past week, namely force pushes to the base branch and temporary changes of the same, resulting in humongous changesets/diffstats being shown. This was done to work around some deficiencies in the release process, apologies for the inconvenience. Now that 14.2.20, 15.2.11 and 16.2.1 are out the door, everything has been restored. Jenkins is currently backed up processing "make check" and "ceph API tests" jobs, but it should clear up by tomorrow. Please retrigger with "jenkins test make check", "jenkins test api", etc if needed. Some of you have clicked the unhelpful "Update branch" button, which generated an unneeded merge commit. Please get rid of it, either by rebasing or simply rolling back to the parent. I went through the PRs and commented on those that need action, but please double check that there are no merge commits or unrelated changes in the "Commits" list before merging. Thanks, Ilya

New RBD PTL

by Gregory Farnum

Hey all, A couple months ago Jason Dillaman, our long-time RBD tech lead, moved on from his job at Red Hat working on Ceph to a new opportunity. This left a hole in the team we needed to fill on short notice, and because I was asked to backfill Jason in Red Hat's internal affairs I also took on some of his upstream tech lead duties on a fill-in basis — I don't think this was ever discussed on the lists but it came up in CDM and some meetings. However, we've had more time since then to converse among the relevant people and I am happy to announce that Ilya Dryomov has agreed to take over the PTL role for RBD. Many of you know Ilya for his work throughout Ceph's kernel clients (including especially the RBD module) and sometime wrangling of security issues in our messaging layers, and I look forward to him expanding his leadership role in the project. Thanks! -Greg
