September 2023 - Dev - lists.ceph.io

by Casey Bodley

hey Gal and Eric, in today's standup, we discussed the version of our apache arrow submodule. it's currently pinned at 6.0.1, which was tagged in nov. 2021. the centos9 builds are using the system package libarrow-devel-9.0.0. arrow's upstream recently tagged an 11.0.0 release as far as i know, there still aren't any system packages for ubuntu, so we're likely to be stuck with the submodule for quite a while. how do guys want to handle these updates? is it worth trying to update before the reef release?

Debian packages for Reef - any chance of reviews / builds?

by Matthew Vernon

Hi, When Reef was released, the announcement said that Debian packages would be built once the blocking bug in Bookworm was fixed. As I noted on the tracker item https://tracker.ceph.com/issues/61845 a couple of weeks ago, that is now the case after the most recent Bookworm point release. I also opened a PR to make the minimal change that would build Reef packages on Bookworm[0]. I subsequently opened another PR to fix some low-hanging fruit in terms of packaging errors - missing #! in maintscripts, syntax errors in debian/control, erroneous dependencies on Essential packages[1]. Neither PR has had any feedback/review as far as I can see. Those packages (and the previous state of the debian/ tree) had some significant problems - no copyright file, and some of them contain python scripts without declaring a python dependency, so I've today submitted a slightly larger PR that brings the dh compatibility level up to what I think the latest lowest-common-denominator level is, as well as fixing these errors[2]. I believe these changes all ought to go into the reef branch, but obviously you might prefer to just make the bare-minimum-to-build change in the first PR. Is there any chance of having some reef packages for Bookworm, please? Relatedly, is there interest in further packaging fixes for future branches? lintian still has quite a lot to say about the .debs for Ceph, and while you might reasonably not want to care about crossing every t of Debian policy, I think there are still changes that would be worth doing... I should declare a bit of an interest here - I'd like to evaluate cephadm for work use, which would require us to be able to build our own packages per local policy[3], which in turn would mean I'd want to get Debian-based images going again. But that requires Reef .debs being available to install onto said images :) Thanks, Matthew [0] https://github.com/ceph/ceph/pull/53342 [1] https://github.com/ceph/ceph/pull/53397 [2] https://github.com/ceph/ceph/pull/53546 [3] https://wikitech.wikimedia.org/wiki/Kubernetes/Images#Production_images

"Unable to locate package ceph-libboostXXX" with install-deps.sh on ubuntu

So far, I haven't been able to reproduce it on a jammy container (the install-deps.sh script runs fine to completion when I run the script). Wondering if some environmental factor is related to this issue, or if anyone has found a workaround.

Quincy 17.2.7 - is there a plan?

by Michał Nasiadka

Hello, It’s been surely quite some months since Quincy 17.2.6 release (April) - I think we’ve all had some issues with the mclock scheduler backfill bug [1] that is patched in the Quincy branch - but not released. Can I please ask for some plan for Quincy 17.2.7? I think that’s a bit more than advertised 4-6 weeks (https://docs.ceph.com/en/latest/releases/general/#stable-releases-x-2-z) [1]: https://www.spinics.net/lists/ceph-users/msg77209.html

Ceph leadership team notes 9/27

by Gregory Farnum

Hi everybody, The CLT met today as usual. We only had a few topics under discussion: * the User + Dev relaunch went off well! We’d like reliable recordings and have found Jitsi to be somewhat glitchy; Laura will communicate about workarounds for that while we work on a longer-term solution (self-hosting Jitsi has a better reputation and is a possibility). We also discussed a GitHub repo for hosting presentation files, and organizing them on the website. * CVE handling. As noted elsewhere on the mailing list, CVE-2023-43040 (a privilege escalation impacting RGW) was disclosed elsewhere, and we do not have coordinated releases for it. This was not deemed important enough on the security list for that effort, but we do want to be more prepared for it than we were — our CVE handling process has broken down a bit since some of the CVE work is now being handled by IBM instead of Red Hat. Tech leads and IBM employees will be working on refining that so we have better disclosures. Also, if you were previously on the security mailing list and a did not see these emails, please reach out to the team — some subscribers were lost and not recovered in the lab disaster end of last year. (For obvious reasons this is a closed list — if you do not work for a Linux distribution or at a large deployer with established relationships in Ceph and security communities, it’s hard for us to put you there.) -Greg

Grace Hopper Open Source Day happening today!

by Laura Flores

Hi Developers, Ceph is happy to be participating in Grace Hopper Open Source Day [1], an all-day hackathon for beginning programmers! You may see some pull requests coming into the Ceph repository from participants today, labeled with the tag "open-source-day-2023" [2]. If you'd like to help out, you're welcome to provide feedback for these first-time contributors on the PRs! For many, this is their first introduction to Ceph, so they may need help signing off their commits, passing checks, etc. Thanks everyone, and please reach out to me if you have any questions! - Laura 1. https://ghc.anitab.org/awards-programs/open-source-day/ 2. https://github.com/ceph/ceph/labels/open-source-day-2023 -- Laura Flores She/Her/Hers Software Engineer, Ceph Storage <https://ceph.io> Chicago, IL lflores(a)ibm.com | lflores(a)redhat.com <lflores(a)redhat.com> M: +17087388804
