[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/

mirrorlist code updated / SIGs and AltArch support rolled-in
by Fabian Arrotin 24 Sep '18

24 Sep '18

<paste> Recently I had to update the existing code running behind mirrorlist.centos.org (the service that returns you a list of validated mirrors for yum, see the /etc/yum.repos.d/CentOS*.repo file) as it was still using the Maxmind GeoIP Legacy country database. As you can probably know, Maxmind announced that they're discontinuing the Legacy DB, so that was one reason to update the code. Switching to GeoLite2 , with python2-geoip2 package was really easy to do and so was done already and pushed last month. But that's when I discussed with Anssi (if you don't know him, he's maintaining the CentOS external mirrors DB up2date, including through the centos-mirror list ) that we thought about not only doing that change there, but in the whole chain (so on our "mirror crawler" node, and also for the isoredirect.centos.org service), and random chat like these are good because suddenly we don't only want to "fix" one thing, but also take time on enhancing it and so adding more new features. The previous code was already supporting both IPv4 and IPv6, but it was consuming different data sources (as external mirrors were validated differently for ipv4 vs ipv6 connnectivity). So the first thing was to rewrite/combine the new code on the "mirror crawler" process for dual-stack tests, and also reflect that change o nthe frontend (aka mirrorlist.centos.org) nodes. While we were working on this, Anssi proposed to also not adapt the isoredirect.centos.org code, but convert it in the same python format as the mirrorlist.centos.org, which he did. Last big change also that was added is the following : only some repositories/architectures were checked/validated in the past but not all the other ones (so nothing from the SIGs and nothing from AltArch, so no mirrorlist support for i386/armhfp/aarch64/ppc64/ppc64le). While it wasn't a real problem in the past when we launched the SIGs concept, and that we added after that the other architectures (AltArch), we suddenly started suffering from some side-effects : * More and more users "using" RPM content from mirror.centos.org (mainly through SIGs - which is a good indicator that those are successful, which is a good "problem to solve") * We are currently losing some nodes in that mirror.centos.org network (it's still entirely based on free dedicated servers donated to the project) To address first point, offloading more content to the 600+ external mirrors we have right now would be really good, as those nodes have better connectivity than we do, and with more presence around the globe too, so slowly pointing SIGs and AltArch to those external mirrors will help. The other good point is that , as we switched to the GeoLite2 City DB, it gives us more granularity and also for example, instead of "just" returning you a list of 10 validated mirrors for USA (if your request was identified as coming from that country of course), you now get a list of validated mirrors in your state/region instead. That means that then for such big countries having a lot of mirrors, we also better distribute the load amongst all of those, which is a big win for everybody - users and mirrors admins - ) For people interested in the code, you'll see that we just run several instances of the python code, behind Apache running with mod_proxy_balancer. That means that if we just need to increase the number of "instances", it's easy to do but so far it's running great with 5 running instances per node (and we have 4 nodes behind mirrorlist.centos.org) Worth noting that on average, each of those nodes gets 36+ millions requests per week for the mirrorlist service (so 144+ millions in total per week) So in (very) short summary : mirrorlist.centos.org code now supports SIGs/AltArch repositories (we'll sync with SIGs to update their .repo file to use mirrorlist= instead of baseurl= soon) we have better accuracy for large countries, so we redirect you to a 'closer' validated mirror </paste> So that means that now the following combination are possible through mirrorlist: testing base os for aarch64 : curl 'http://mirrorlist.centos.org/?release=7&arch=aarch64&repo=os' testing RDO Rocky release for ppc64le : curl 'http://mirrorlist.centos.org/?release=7&arch=ppc64le&repo=cloud-openstack-r…' And so on .... :) There is no "pressure" to update your -release pkg to switch from baseurl=mirror.centos.org to mirrorlist=mirrorlist.centos.org but I just wanted to inform that it's now "live" and you can start thinking about that change, and why not with an update pkg just pushed to -testing (aka buildlogs.centos.org) and then move to that later ?

Get Started There are three ways to get started with RDO. To spin up a proof of concept cloud, quickly, and on limited hardware, try an All-In-One Packstack installation <https://www.rdoproject.org/install/packstack/>. You can run RDO on a single node to get a feel for how it works. For a production deployment of RDO, use the TripleO Quickstart <https://www.rdoproject.org/tripleo/> and you’ll be running a production cloud in short order. Finally, for those that don’t have any hardware or physical resources, there’s the OpenStack Global Passport Program <https://www.openstack.org/passport>. This is a collaborative effort between OpenStack public cloud providers to let you experience the freedom, performance and interoperability of open source infrastructure. You can quickly and easily gain access to OpenStack infrastructure via trial programs from participating OpenStack public cloud providers around the world. Get Help The RDO Project participates in a Q&A service at https://ask.openstack.org. We also have our [users(a)lists.rdoproject.org[( https://lists.rdoproject.org/mailman/listinfo/users) for RDO-specific users and operrators. For more developer-oriented content we recommend joining the dev(a)lists.rdoproject.org mailing list <https://lists.rdoproject.org/mailman/listinfo/dev>. Remember to post a brief introduction about yourself and your RDO story. The mailing lists archives are all available at https://mail.rdoproject.org <https://lists.rdoproject.org/mailman/listinfo>. You can also find extensive documentation on RDOproject.org <https://www.rdoproject.org/>. The #rdo channel on Freenode IRC is also an excellent place to find and give help.

[OpsTools] Introduction & Joining Request
by Christian Gebler 20 Sep '18

20 Sep '18

Hello everyone, my name is Christian and I would like to be part of CentOS OpsTools SIG. I'm a sysadmin for about 15 years now with a main focus on web application hosting. Most of the time in a global IT environment and with the goal to keep the systems secure, highly available and on a good performance. I often had to use a linux distributions that the customer wanted to use, but in the last 5 years I am in the lucky position to mainly use CentOS. (-: I have read the SIG wiki page with great enthusiasm and want to contribute something useful to the group. So my questions are...how can I join the OpsTools SIG and how can I easily start to contribute something useful to the group? Thanks a lot! (-: - Chris

Doubt on mmap :kernel-3.10.0-693.11.6.el7
by Prem Kumar 19 Sep '18

19 Sep '18

We are trying to map the disk file and content is written in to specific offset. In meanwhile, if try to access the mmap'd content at specified offset, we are getting NULL value. we have not called msync() yet. the mmap called with MAP_SHARED. Is it possible that mmap content can differ on read after write or is this the problem happening because read is called before the msync(). Thanks, Prem

Authorization to use CentOS logo in GNOME Boxes
by Fabiano Fidêncio 19 Sep '18

19 Sep '18

People, Firstly, sorry for the cross-list post (centos-devel and centos-docs). I'd like to reach you in order to ask for a formal authorization to use CentOS logo on GNOME Boxes[0]. GNOME Boxes already shows a few other distro's logos as you can check here[1]. Would be possible to get the explicit confirmation that we could use CentOS logo as well? [0]: https://wiki.gnome.org/Apps/Boxes [1]: https://gitlab.gnome.org/GNOME/gnome-boxes/raw/master/README.logos Best Regards, -- Fabiano Fidêncio

Hurricane Florence and CentOS CI/CBS
by Brian Stinson 12 Sep '18

12 Sep '18

Hi All, Some of you may know that the CentOS Community Build System, and CentOS CI Infrastructures are hosted in Raleigh, North Carolina. I wanted to take this opportunity to let all of you know that outages are possible (but not expected) in the coming days as Hurricane Florence makes its way toward the US East coast. We are confident in the precautions taken by our datacenter vendor, and in the preparedness plans by our DC operations team. If there happen to be outages, we will work to get things back as soon as we can. Cheers! -- Brian Stinson CentOS Infrastructure Team
