March 2024 - Dev - lists.ceph.io

by Neha Ojha

Hi everyone, On behalf of the Ceph Foundation Board, I would like to announce the creation of, and cordially invite you to, the first of a recurring series of meetings focused solely on gathering feedback from the users of Ceph. The overarching goal of these meetings is to elicit feedback from the users, companies, and organizations who use Ceph in their production environments. You can find more details about the motivation behind this effort in our user survey [1] that we highly encourage all of you to take. This is an extension of the Ceph User Dev Meeting with concerted focus on Performance (led by Vincent Hsu, IBM) and Orchestration/Deployment (led by Matt Leonard, Bloomberg), to start off with. We would like to kick off this series of meetings on March 21, 2024. The survey will be open until March 18, 2024. Looking forward to hearing from you! Thanks, Neha [1] https://docs.google.com/forms/d/15aWxoG4wSQz7ziBaReVNYVv94jA0dSNQsDJGqmHCLM…

Restricted access to /teuthology on teuthology.front.sepia.ceph.com

by Patrick Donnelly

Hi folks, As many of you are aware, RAM/CPU is particularly scarce on teuthology.front.sepia.ceph.com which means that any log viewing of QA results can cause swapping and general slowness. At today's Ceph Infrastructure Weekly call [1], I proposed only allowing root, www-data, and teuthworker access to /teuthology so that others would be forced to look at logs on other beefier development machines like senta [2], vossi [3], your personal workstation [4], or even some temporary locked node [5]. The current plan is to proceed barring some reasonable justification not to. There are a few to-do items to make it happen laid out in the minutes. Until then, admins of teuthology would appreciate it if you already start moving your log viewing to other machines without waiting for a technical barrier to be set up.

ceph-object-corpus test coverage

by Casey Bodley

this ceph-object-corpus repo is the basis of our ceph-dencoder test src/test/encoding/readable.sh, which verifies that we can still decode all of the data structures encoded by older ceph versions i'd like to raise awareness that this ceph-object-corpus repo hasn't been updated with new encodings since pacific 16.2.0, so we're missing important regression test coverage since then Nitzan prepared the encodings for reef 18.2.0 in https://github.com/ceph/ceph-object-corpus/pull/17, but those haven't merged yet. i had opened https://github.com/ceph/ceph/pull/54735 to test that, but 'make check' identified failures like: > The following tests FAILED: > 147 - readable.sh (Failed) > > **** reencode of /home/jenkins-build/build/workspace/ceph-pull-requests/ceph-object-corpus/archive/18.2.0/objects/chunk_refs_t/ccb69d9ecd572c1f6ed9598899773cf1 resulted in a different dump **** can we find a way to prioritize this? it would be great to have these reef encodings while we're validating the squid release

there are two important rgw features not yet on squid topic metadata changes for multisite sync: - merged to main, staged on squid in https://github.com/ceph/ceph/pull/56069 - just waiting for upgrade test coverage in https://github.com/ceph/ceph/pull/55214 user account feature: - main pr https://github.com/ceph/ceph/pull/54333 rebased on topic changes, passing qa - integration with topic feature in https://github.com/cbodley/ceph/pull/7 on qa i hope to see these both land within a week or two we're continuing to test/merge bug fixes in the meantime

Call for Interest: Managed SMB Protocol Support

by John Mulligan

Hello Ceph List, I'd like to formally let the wider community know of some work I've been involved with for a while now: adding Managed SMB Protocol Support to Ceph. SMB being the well known network file protocol native to Windows systems and supported by MacOS (and Linux). The other key word "managed" meaning integrating with Ceph management tooling - in this particular case cephadm for orchestration and eventually a new MGR module for managing SMB shares. The effort is still in it's very early stages. We have a PR adding initial support for Samba Containers to cephadm [1] and a prototype for an smb MGR module [2]. We plan on using container images based on the samba-container project [3] - a team I am already part of. What we're aiming for is a feature set similar to the current NFS integration in Ceph, but with a focus on bridging non-Linux/Unix clients to CephFS using a protocol built into those systems. A few major features we have planned include: * Standalone servers (internally defined users/groups) * Active Directory Domain Member Servers * Clustered Samba support * Exporting Samba stats via Prometheus metrics * A `ceph` cli workflow loosely based on the nfs mgr module I wanted to share this information in case there's wider community interest in this effort. I'm happy to take your questions / thoughts / suggestions in this email thread, via Ceph slack (or IRC), or feel free to attend a Ceph Orchestration weekly meeting! I try regularly attend and we sometimes discuss design aspects of the smb effort there. It's on the Ceph Community Calendar. Thanks! [1] - https://github.com/ceph/ceph/pull/55068 [2] - https://github.com/ceph/ceph/pull/56350 [3] - https://github.com/samba-in-kubernetes/samba-container/ Thanks for reading, --John Mulligan

on dropping ubuntu focal support for squid

by Casey Bodley

there was a consensus to drop support for ubuntu focal and centos stream 8 with the squid release, and i'd love to remove those distros from the shaman build matrix for squid and main branches asap however, i see that quincy never supported ubuntu jammy, so our quincy upgrade tests still have to run against focal. that means we'd still have to build focal packages for squid would it be possible to start building jammy packages for quincy to allow those upgrade tests to run jammy instead? this isn't an issue on the centos side because we've been building centos 9 packages for quincy even though it's not listed in https://docs.ceph.com/en/latest/start/os-recommendations/#platforms

by Casey Bodley

Ubuntu 22.04 packages are now available for the 17.2.7 Quincy release. The upcoming Squid release will not support Ubuntu 20.04 (Focal Fossa). Ubuntu users planning to upgrade from Quincy to Squid will first need to perform a distro upgrade to 22.04. Getting Ceph ------------ * Git at git://github.com/ceph/ceph.git * Tarball at https://download.ceph.com/tarballs/ceph-17.2.7.tar.gz * Containers at https://quay.io/repository/ceph/ceph * For packages, see https://docs.ceph.com/en/latest/install/get-packages/ * Release git sha1: b12291d110049b2f35e32e0de30d70e9a4c060d2

el9 container builds

by Ken Dreyer

Hi Guillaume, We need to move the Squid release to use a CentOS Stream 9 image instead of 8. (CentOS Stream 8 is EOL in a few months.) We also want to move Ceph's Dockerfile (https://github.com/ceph/ceph-container/issues/2171) What is the next step to accomplish these goals?

Jenkins multiple jobs waiting in the queue without building

by Suyash Dongre

There are multiple jobs that have been in the queue over ten hours without starting to build Which Jenkins version are we using? Jenkins 2.222.3, 2.205 or anything in between have this issue where jobs are waiting for multiple hours without starting to build. Using Jenkins 2.204.6 or earlier tends to solve this issue.
