[Infra] - Planned outage : lists.centos.org (Nov 4th)
by Fabian Arrotin 31 Oct '25

31 Oct '25

Due to a DC move, we'll have to migrate the existing CentOS mail server/mailing list server (aka https://lists.centos.org) to a new server. Migration is scheduled for """"Tuesday November 4th, 8:00 am UTC time"""". You can convert to local time with $(date -d '2025-11-04 08:00 UTC') The expected "downtime" is estimated to ~15 minutes , time needed to : - backup/restore last mysql dump - synchronize mailman3 archives (hyperkitty) - verify service and switch DNS to point to new host. Thanks for your understanding and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

CentOS Infra DC move status : ready to go !
by Fabian Arrotin 31 Oct '25

31 Oct '25

hi all, As announced some months ago, majority of (centralized and sponsored by Red Hat) CentOS infra has to move from current DC (RDU2 - aka "Community Cage") to RDU3. That's where our friends (and colleagues) from Fedora recently migrated to some months ago. It's so now our turn and we worked with DC/Network team[s] to have all ready and be in a position where we'd be able to move/migrate all services from one DC to the other. Some services are already migrated and running from new DC (or from the Cloud), but we haven't announced these changes, as it had no impact in the way you (SIGs developers) are interacting with these services. For example, the whole CentOS CI infra (all components) are now running exclusively from AWS (special note : we'll have from new DC a tunnel to offer - as it was in the past - some ppc64le instances for duffy). Same for our MQTT broker and some other services (running now from RDU3) We already started to replicate our storage used in RDU2 to RDU3 (mainly for koji share volume for cbs.centos.org) and it's all on track. We'll though announce in the next days/weeks some changes like : - lookaside cache server migration (https://src.sigs.centos.org/) - https://lists.centos.org mailman3 server (https//lists.stg.centos.org test instance is already running from new DC) - https://cbs.centos.org Worth knowing that for CBS, we'll shift more to hybrid cloud model, so we'll have some "on prem" machines, but we'll also extend to AWS (for x86_64 and aarch64) for compute capacity. Also good to know that we collaborated with Fedora (running from same DC but different VLANs) to share some IBM Power 10 , so once migrated koji builders for ppc64le will be running on Power 10 (instead of Power 9). There is also a (pending) ticket about adding native risc-v builders to cbs, mainly to bootstrap publicly centos stream 10 but then available also for SIGs/community members (once there will be something usage), so adding another arch on our koji build infra (so we'll be supporting x86_64, aarch64, ppc64le, s390x and risc-v) So stay tuned for more information to come about each of these services in the following days. -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

CentOS Connect
by Shaun McCance 24 Oct '25

24 Oct '25

Hi folks, We've announced CentOS Connect for January 29-30, 2026, in Brussels, Belgium. As usual, this is the two days before FOSDEM. https://www.centos.org/events/connect/ The CFP and registration are now open. Registration is free, but we really need you to register to help us plan. Details are on the website. We have a hotel room block, but don't have booking link just yet. Check back next week. We're looking into some options for a reception, which could be on the Thursday or Friday. If you attended last year, you might remember our waffle party. That was a blast, but we completely filled the place with no room to grow. Stay tuned. We'll also hold a docs day on Monday, February 2, the day after FOSDEM. We've done this the last few years. This is a working session to hack on the website and docs. If you want to join, get in touch with the Docs SIG at sig-docs(a)centosproject.org . Let me know if you have any question. I'm looking forward to seeing a lot of you in Brussels again. Thanks, Shaun

New external-repo available in CBS - epel10z
by Greg Sutcliffe 10 Oct '25

10 Oct '25

Hey folks, Recently, we got a request to add an `epel10z` external-repo to Koji - you can check [1] for details on the longer background, but the short version is that EPEL has shifted to Stream by default, and so they have a corresponding EPEL branch that tracks RHEL major.minor (that is, epel10 = CentOS Stream 10, and epel10z = current RHEL 10.minor). You can see this in the EPEL 10 repo file [2], resolving to `epel/10z` for RHEL 10 builds. We've added the external-repo to Koji, and made it available: ``` $ cbs list-external-repos|grep z epel10z http://dl.fedoraproject.org/pub/epel/10z/Everything/$arch/ $ cbs taginfo kmods10-repos-main-el10-build | grep epel10z 20 epel10z (http://dl.fedoraproject.org/pub/epel/10z/Everything/$arch/, merge mode: bare), arches: inherited from tag ``` If this is something your tag(s) want to use, please open a ticket [3] as usual. Thanks! Greg PS.

RFC - debuginfod.centos.org usage (Stream 8 packages)
by Fabian Arrotin 05 Oct '25

05 Oct '25

[Request for Comments] We recently got a zabbix alert about disk threshold usage on https://debuginfod.centos.org service. As a reminder (and for context), while all previous centos linux releases had (for efficiency reasons) a split between .src.rpm (going to https://vault.centos.org) and *debuginfo* rpm packages (consuming a lot of bandwidth/disk space) going to http://debuginfo.centos.org , the plan changed when Stream 8 (and so Stream 9 and 10 too) landed. All packages were pushed out to mirror network, but not all variants (multiple ones due to Stream nature) were kept online. We were asked to provide a similar service to what Fedora was already offering and so that's how https://debuginfod.centos.org/ came to life : for people willing to debug pkgs, they can request "on the fly" corresponding debuginfo files/packages (see website for simple instructions) Now the question (and requests for comments) : We were still carrying on that server all the Stream 8 debuginfo packages, while technically not needed anymore (Stream 8 was removed from all mirrors when it went EOL in May 2024) ... But based on analysis done with Frank Eigler (maintaining the service with us), we discovered that in fact a third of all requests for debuginfod service are still about stream 8 (vs Stream 9 and 10) The question is so : can we just delete (imho, yes !) these old .el8. debuginfo packages (probably just analyzed in loop by AI scrapers these days) and so : - limit bandwidth needed for that machine - reclaim some storage space (instead of increasing in loop the backend disks) Opinions, thoughts, comments ? -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]
