(How) do others SIGs provide kernel modules?
by Niels de Vos 07 Oct '18

07 Oct '18

Hi, There is an oustanding request for the Storage SIG to package and provide VDO: > VDO (which includes kvdo and vdo) is software that provides inline > block-level deduplication, compression, and thin provisioning > capabilities for primary storage. Both components ate packaged in a Fedora COPR, and a reasonable .spec file is provided by the upstream project. However, the kernel module is packaged with DKMS. This would result in building the module during RPM installation, and possibly on reboot after a kernel update. There is a dkms package in the CBS (by Haïkel), but it is only tagged with -candidate. I would like to know what the reasons were to not consumer it for a release. It seems that there is one (that I could find) package in the CBS that provides a kernel modules (openafs-kmod by Jonathan). It utilizes DKMS as well, but also never made it a repository for release. Then there is the kmod package (build by Lokesh). This is an alternative way of building kernel modules. It compiles the module in the CBS, for a specific (sortof major) kernel version. The resulting RPM can then be installed without the need to build it again. My personal preference would be to provide kernel modules with the kmod practise. But I love to hear opinions and experiences from others. Thanks, Niels

scap-security-guide rebuild problem
by aleksander.baranowski 04 Oct '18

04 Oct '18

Hi, I recently tried to rebuild: http://ftp.scientificlinux.org/linux/scientific/7.5/SRPMS/vendor/scap-secur… or CentOS: http://vault.centos.org/7.5.1804/updates/Source/SPackages/scap-security-gui… or http://vault.centos.org/7.5.1804/updates/Source/SPackages/scap-security-gui… and failed miserably :(. Steps to reproduce: ```bash sudo yum install @development wget libxslt openscap-scanner python-lxml cmake -y wget http://ftp.scientificlinux.org/linux/scientific/7.5/SRPMS/vendor/scap-secur… rpmbuild --rebuild scap-security-guide-0.1.36-10.sl7_5.src.rpm ``` Or with mock ``` mock scap-security-guide-0.1.36-10.sl7_5.src.rpm ``` The patch that breaks build is scap-security-guide-0.1.39-fix-failing-rules-for-PCI-DSS-DISA-UGSCB.patch. It has number 12 in the spec file. Is there anything that I'm missing? Unfortunately, I'm unable to find scap-security-guide on CentOS CBS, so I'm clueless. Bests, Alex

Next weekend, CentOS will be sponsoring Ohio LinuxFest, and will have a table there. If you expect to be at OLF, and can spare an hour, or even a half hour, to sit at the table and answer questions, it would be a great help to me. Please have a look at the schedule - https://ohiolinux.org/schedule/ - and let me know what time(s) you might be able to spend at the table. For your convenience, I've made a list of available times here: https://docs.google.com/spreadsheets/d/1TqTqaLoswMYzyfvQCnzjkVazlQkP87CCKBS… Thanks, and I hope to see some of you in Columbus. --Rich -- Rich Bowen - rbowen(a)redhat.com @CentOSProject // @rbowen 859 351 9166

CentOS Community Container Pipeline: re-architecture migration window
by Bamacharan Kundu 03 Oct '18

03 Oct '18

Hi, Since last few months, we were working on re-architecturing the CentOS Community Container Pipeline Service to make https://registry.centos.org as a stable and reliable source for CentOS based container images. We are now done with the changes for better throughput and stability. We are working on deploying the new service in production in coming weekend (between 28th Sep 2018- 1st Oct 2018). During this time service will be in maintenance mode. We will not be building new images for registry.centos.org. Existing images will not be updated based on RPM, or git source updates. However, during this migration registry.centos.org will be available to pull images from. We are trying to make sure the down time for CentOS Community Container pipeline service is minimal. Service: https://registry.centos.org Maintenance window: Service will not have downtime Impact: Users will be able to pull images from https://registry.centos.org Service: CentOS Container Community Pipeline Service Maintenance window: 28th Sep 2018 to 1st Oct 2018 (We are working on to make it minimal) Impact: PRs to https://github.com/centos/container-index will not be merged and no image updates are pushed to registry.centos.org. Sorry for the inconvenience, we will keep posted. Regards Bama Charan Kundu

The Call for Presentations for the FOSDEM Dojo - https://wiki.centos.org/Events/Dojo/Brussels2019 - closes next weekend. And, so far, it's looking pretty grim, with only THREE submissions. If you anticipate being at FOSDEM, and would like to present at our annual FOSDEM Dojo on topics relevant to CentOS or Fedora, please consider submitting a talk: https://goo.gl/forms/XkXbC2AZBgKvfDNF2 Please see https://wiki.centos.org/Events/Dojo/Brussels2018 for some idea of what kind of talks we had last year. But we're also asking the Fedora community to submit talks this year. --Rich -- Rich Bowen - rbowen(a)redhat.com @CentOSProject // @rbowen 859 351 9166

Problems with qemu-img when generating Vagrant images
by Laurentiu Pancescu 02 Oct '18

02 Oct '18

Hello everyone, we switched from using qemu-img from CentOS 7.x to qemu-img-ev from the Virt SIG several months ago, to allow us to generate Hyper-V images. My attempts to build Vagrant images are failing the automated tests since the beginning of July, apparently due to corrupt filesystems. I see XFS metadata corruption in the CentOS 7 images when using qemu-img-ev, as well as ext4 superblock corruption in the CentOS 6 images.[1] The distro installer runs just once and the resulting disk image is converted by Image Factory to different formats, depending on the virtualization target. Since the VirtualBox images are working as expected, while the libvirt images don't even boot due to filesystem corruption, I would assume that the installation produces a valid image, but the conversion of the disk images for libvirt-kvm fall prey to bugs in qemu-img-ev and the stock qemu-img. If anyone has the possibility to test with VmWare or Hyper-V, please write me off-list. I noticed that qemu-img-ev is at version 2.1.2, while Debian Stable has version 2.8 and Fedora 28 has version 2.11. Maybe such bugs, if real, were already fixed upstream - would it be possible to use a newer version than what qemu-img-ev provides? We reverted to using the EL7 qemu-img, but this still produces broken libvirt images and wețd have to drop the Hyper-V images as well. Any help or suggestions are appreciated. Best regards, Laurențiu [1] https://people.centos.org/bstinson/vagrant/c6-vagrant.png

[ppc64le] Request for publishing sensu in ppc64le opstools
by Michael Turek 25 Sep '18

25 Sep '18

Hello, Trevor Vardeman <Vorrtex>, Adam Kimball <baha>, and myself <mjturek> have been looking into TripleO container builds for ppc64le. This led to finding some missing dependencies. The current one we're struggling with is sensu. It seems like all of the dependencies for running sensu are published in ppc64le-opstools [0]. Additionally, the sensu package itself is noarch. Is there anything we could do to get this package published? Thanks! Mike Turek <mjturek> [0] http://mirror.centos.org/altarch/7/opstools/ppc64le/sensu/
