Proposal: CentOS Public Board Meetings
by Rich Bowen 07 Jan '23

07 Jan '23

In January of 2021, the CentOS Board of Directors opened our monthly meetings to all SIG chairs, in a first step towards more transparent governance. We wanted to see how the larger audience changed the meeting dynamics, if at all, as well as welcoming a broader pool of voices. We are now ready for the second part of this process. Starting in the August meeting, we will be inviting the entire CentOS community to attend these meetings. Due to the nature of the Internet, we won’t be simply publishing the meeting URL, as this often leads to disruptive behavior in meetings, as I am sure many of you have experienced. Rather, in the week before the meeting, we’ll send, to this list, a way to request an invitation to the meeting. In this way, we hope to limit the incidence of such disruptions, while also making the meeting available to anyone who wishes to attend. We will be working on the rules of engagement for these meetings, but they will be, at minimum: * Wait to be recognized by the Chair before speaking * Respect the Chair when told your time to speak is over - this will allow us to remain on agenda, and complete the meetings in the allotted time * In the event that there are Board-confidential topics, these will be put at the end of the meeting, in Executive Session, and guests will be asked to leave. We hope to minimize these items, but they do sometimes happen. The most common scenarios in which this may happen are personnel issues, or information that Red Hat wishes to share with the Board, but is not yet public. * Muting of participants, or, in extreme situations, ejection from the meeting, is at the sole discretion of the Chair. * Meetings will be recorded, and published to YouTube (possibly with edits/redactions, as approved by the Directors). Thus, by joining the meeting you consent to have your presence at the meeting, and anything you say during the meeting, made public. Because there will seldom be time for Q&A during the meeting itself, we plan to add a post-meeting IRC office hours session for followup questions. This will probably be scheduled for a week after the board meeting, to allow time to publish meeting minutes We welcome your comments about the above proposal, and thank you all for your patience as we implement these changes to our governance process.

GTK 2 removal from RHEL 10+
by Tomáš Popela 06 Jan '23

06 Jan '23

Hi everyone, I'm actually resending this again, as I've sent it here at the same time as to fedora-devel ( https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org…) but it probably never reached centos-devel as I'm not able to find it in archives. This is an early heads-up about GTK 2 removal from RHEL 10+ (the gtk2 package was marked as unwanted in ELN with https://github.com/minimization/content-resolver-input/commit/b6d44e496f46b…) The toolkit served us gratefully, but it starts to show its age with regards to modern technologies such as Wayland, HiDPI screens, HDR and others. In RHEL 10 the GTK 3 and GTK 4 will still continue to be available for everyone to use.

Sorry for the long title, I will work on that :) Below are the meeting minutes from the Infra SIGs last session in December 2022.

CentOS Hyperscale SIG meetup @ Connect/FOSDEM 2023
by Davide Cavalca 05 Jan '23

05 Jan '23

Hello, The CentOS Hyperscale SIG will be holding an in-person meetup on on February 2nd, 2023 at DoubleTree Brussels City Center Hotel. This is the same venue hosting CentOS Connect on February 3rd, and only a short walk from where FOSDEM will be held over the weekend. The meetup is open to everybody interested -- you don't have to be a member of the SIG to attend, and we'd welcome participation from anyone interested in this space. The event will be held from 9am to 5pm in the Birth room at the DoubleTree hotel. While this is an in-person event, we will do our best to setup a conference bridge so that remote participants can attend and interact as well. Please register at https://www.eventbrite.com/e/centos-hyperscale-sig-meetup-connectfosdem-202… to help with the event planning. Cheers Davide

Pruning old/scratch jobs from cbs.centos.org koji storage
by Fabian Arrotin 04 Jan '23

04 Jan '23

Hi all, We recently reviewed our storage consumption and one thing I realized is that, apart from running on out-of-warranty, the nfs share used by cbs.centos.org koji is growing (which is a good sign that people/SIGs are using it) but also with things that shouldn't stay behind, like temporary scratch (test) builds. Problem is that apart from consuming disk space on that nfs storage node, it's also consuming resources on the (older) backup node, also extending the needed time to take backup. I intend (in the following days) to implement through ansible a script itself just based on upstream koji-prune-scratch one (https://pagure.io/koji-tools/blob/master/f/src/bin/koji-prune-scratch) I'd like to start cleaning (deleting) scratch jobs that are (like in that upstream script) more than 7 days (scratch builds aren't proper builds and so are never tagged and so never signed/pushed out to mirrors). -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab@fosstodon.org

by Troy Dawson 22 Dec '22

22 Dec '22

Meeting summary --------------- * Image build systems: livecd and kiwi - Infra ticket to create build targets in CBS https://pagure.io/centos-infra/issue/988 -- Looks like nothing is going to happen until next year. But it looks like it will be done before the ImageBuilder stuff happens. - koji is not importing all the comps stuff needed -- https://pagure.io/koji/issue/3626 -- koji skips environment and category groups when importing the comps files. -- The workaround it to use just regular groups for everything. It's alot more work, but at least it is possible. - Neal's backport of the upstreamed kiwi-live feature to support automatic persistent overlays on live USBs was merged into RHEL 9's dracut and it should be in c9s now: https://kojihub.stream.centos.org/koji/buildinfo?buildID=27844 -- Some anaconda patches/fixes are needed so this doing break installations from livecd's. * Image build systems: ImageBuilder - Infra ticket to create build targets in CBS https://pagure.io/centos-infra/issue/971 -- Not expected to get any movement from infra until next year. * Open Floor - Clarified that meetings are twice a month, on the 2nd and 4th Thursday -- Next meeting will be on January 12, 2023 at the usual time.

Changes to CentOS CI: New OpenShift instance and Updates
by Camila Granella 22 Dec '22

22 Dec '22

*TL;DR: new OpenShift instance is up and running for CentOS CI, migrate your workloads by March 31st, 2023. Test your access to both the Duffy API and the new OpenShift instance by the end of 2022. CentOS CI changes approaching the end of Phase 3. * Hello everyone, We are happy to announce that the new OpenShift instance is up and running (ticket [0]). For the tenants that opted in to continue using CentOS CI, you are being required to *migrate your workload to the new OpenShift instance by the end of Q1CY23*, with the final deadline being *March 31st, 2023*. In order to support you through the migration process, the team has created a quick guide that can be found in [1]. We would also like to request you test your access to both the Duffy API and the new OpenShift instance by the *end of 2022*. Please reach out to us in case it is not working. Here is the link to the new OCP cluster [2]. As a reminder, this new OCP cluster is running in AWS, on top of EC2 instances, so coming with different limitations when compared with “on-premises bare-metal OCP deployments”. One notable change is that it is not possible to expose /dev/kvm and so there is no way for tenants to deploy VMs through OpenShift (like with the kubevirt operator or else). Tenants having a need to use VMs can then request some through Duffy API. Finally, here's a friendly reminder of the CentOS CI changes' current status. According to our previous communications [3], we are approaching the end of the last phase of the changes that have been implemented to CentOS CI. *Phase 3 - Decommission* - Legacy/compatibility API deprecated and requests (even for EC2 instances) will no longer be accepted - All tenants that opted in will be using only EC2 for aarch64/x86_64 and on-premise cloud for ppc64le For a full description of the project phases, you can check [3]. Please, feel free to reach out to us in case you have any questions or concerns. Regards, [0] https://pagure.io/centos-infra/issue/969 [1] https://sigs.centos.org/guide/ci/#migration-to-new-ci-instance [2] https://console-openshift-console.apps.ocp.cloud.ci.centos.org/ [3] https://lists.centos.org/pipermail/ci-users/2022-June/004547.html -- Camila Granella Associate Manager, Software Engineering Red Hat <https://www.redhat.com/> @Red Hat <https://twitter.com/redhat> Red Hat <https://www.linkedin.com/company/red-hat> Red Hat <https://www.facebook.com/RedHatInc> <https://www.redhat.com/>

FreeIPA / Samba / SSSD - new packages same problems

21 Dec '22

Hi gents. It seems this has been a routine - each time when either sssd or Samba or FreeIPA gets new releases (with freeIPA deployed) there will be 'rpm' conflicts: Problem 1: package sssd-common-pac-2.7.3-5.el8.x86_64 requires libndr.so.2()(64bit), but none of the providers can be installed - package sssd-common-pac-2.7.3-5.el8.x86_64 requires libndr.so.2(NDR_0.0.1)(64bit), but none of the providers can be installed - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.16.4-2.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.15.3-0.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.15.4-0.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.15.5-0.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.15.5-3.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.15.5-4.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.15.5-5.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.15.5-8.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.16.1-0.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.16.2-1.el8.x86_64 - cannot install both samba-client-libs-4.17.2-2.el8.x86_64 and samba-client-libs-4.16.4-1.el8.x86_64 - cannot install the best update candidate for package sssd-common-pac-2.7.3-4.el8.x86_64 - cannot install the best update candidate for package samba-client-libs-4.16.4-2.el8.x86_64 Problem 2: package sssd-idp-2.7.3-4.el8.x86_64 requires sssd-common = 2.7.3-4.el8, but none of the providers can be installed - package libsss_autofs-2.7.3-5.el8.x86_64 conflicts with sssd-common < 2.7.3-5.el8 provided by sssd-common-2.7.3-4.el8.x86_64 - cannot install the best update candidate for package sssd-idp-2.7.3-4.el8.x86_64 - cannot install the best update candidate for package libsss_autofs-2.7.3-4.el8.x86_64 Problem 3: package sssd-common-pac-2.7.3-5.el8.x86_64 requires libndr.so.2()(64bit), but none of the providers can be installed - package sssd-common-pac-2.7.3-5.el8.x86_64 requires libndr.so.2(NDR_0.0.1)(64bit), but none of the providers can be installed Or it's just me? many thanks, L.
