Is Oracle a real alternative to Centos?
by Frank Cox 17 Dec '20

17 Dec '20

Is Oracle a real alternative to Centos? I'm asking because genuinely don't know; I've never paid any attention to Oracle's Linux offering before now. But today I've seen a couple of the folks here mention Oracle Linux and I see that Oracle even offers a script to convert Centos 7 to Oracle. Nothing about Centos 8 in that script, though. https://linux.oracle.com/switch/centos/ That page seems to say that Oracle Linux is everything that Centos was prior to today's announcement. But someone else here just said that the first thing Oracle Linux does is to sign you up for an Oracle account. So, for people who know a lot more about these things than I do, what's the downside of using Oracle Linux versus Centos? I assume that things like epel/rpmfusion/etc will work just as they do under Centos since it's supposed to be bit-for-bit compatible like Centos was. What does the "sign up with Oracle" stuff actually do, and can you cancel, avoid, or strip it out if you don't want it? Based on my extremely limited knowledge around Oracle Linux, it sounds like that might be a go-to solution for Centos refugees. But is it, really? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

https://blog.centos.org/2020/12/future-is-centos-stream/
by Rich Bowen 16 Dec '20

16 Dec '20

The future of the CentOS Project is CentOS Stream, and over the next year we’ll be shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream, which tracks just ahead of a current RHEL release. CentOS Linux 8, as a rebuild of RHEL 8, will end at the end of 2021. CentOS Stream continues after that date, serving as the upstream (development) branch of Red Hat Enterprise Linux. Meanwhile, we understand many of you are deeply invested in CentOS Linux 7, and we’ll continue to produce that version through the remainder of the RHEL 7 life cycle. https://access.redhat.com/support/policy/updates/errata/#Life_Cycle_Dates CentOS Stream will also be the centerpiece of a major shift in collaboration among the CentOS Special Interest Groups (SIGs). This ensures SIGs are developing and testing against what becomes the next version of RHEL. This also provides SIGs a clear single goal, rather than having to build and test for two releases. It gives the CentOS contributor community a great deal of influence in the future of RHEL. And it removes confusion around what “CentOS” means in the Linux distribution ecosystem. When CentOS Linux 8 (the rebuild of RHEL8) ends, your best option will be to migrate to CentOS Stream 8, which is a small delta from CentOS Linux 8, and has regular updates like traditional CentOS Linux releases. If you are using CentOS Linux 8 in a production environment, and are concerned that CentOS Stream will not meet your needs, we encourage you to contact Red Hat about options. We have an FAQ - https://centos.org/distro-faq/ - to help with your information and planning needs, as you figure out how this shift of project focus might affect you.

CentOS advisories for 8 release
by Olivier Bonhomme 16 Dec '20

16 Dec '20

Hello dear CentOS community, I'm writing on this mailing list because I'm discovering CentOS 8 after several years of practice on CentOS 7. One of my main concern about a distribution is Bug Fixes and Security Fixes. For CentOS 7, all fixes where identified on CentOS-Announces lists with CESA, CEBA and CEEA which is a good thing in order to identify how a distribution can be broken, vulnerable. However, I didn't find any announcement for CentOS 8. I tried to investigate about any changes about announcement policies but I didn't find anything reliable. So I'm asking here what is exactly the status about announcements for CentOS 8 ? Is it a thing who totally disappeared replaced by Red Hat advisories or is it something different ? Or maybe it is just not planned yet ? Explanations would be very welcomed. Thanks for your answer Regards, Olivier Bonhomme

Software raid Oddity
by Paul R. Ganci 16 Dec '20

16 Dec '20

I have a CentOS 7.9 system with a software raid 6 root partition. Today something very strange occurred. At 6:45AM the system crashed. I rebooted and when the system came up I had multiple emails indicating that 3 out of 6 drives had failed on the root partition. Strangely I was able to boot into the system and everything was working correctly despite > cat /proc/mdstat also indicating 3 out of 6 drives had failed. Since the system was up and running despite the fact more than 2 drives had failed in the root raid array I decided to reboot the system. Actually I shut it down, waited for the drives to spin down and then restarted. This time when it came back the 3 missing drives were back in the array and a cat /proc/mdstat indicated all 6 drives were again in the raid 6 array. So a few questions: 1.) If 3 our of 6 drives of a raid 6 array supposedly fail, how does the array still function? 2.) Why would a shutdown/restart sequence supposedly fix the array? 3.) My gut suggests that the raid array was never degraded and that my system (i.e. cat /proc/mdstat) was lying to me. Any Opinions? Has anybody else ever seen such strange behavior? -- Paul (ganci(a)nurdog.com) Cell: (303)257-5208

What are the differences between CentOS Linux and CentOS Stream?
by Turritopsis Dohrnii Teo En Ming 16 Dec '20

16 Dec '20

Good day from Singapore, What are the differences between CentOS Linux and CentOS Stream? At the moment, I only know that CentOS 8 support will end on 31 December 2021 while Red Hat Inc will shift its focus to CentOS Stream. Is CentOS Stream going to be very similar to Fedora Linux, shipping with the latest Linux Kernel like 5.10.1? I am looking forward to hearing from you.

What about the AltArch repositories? (+ some experiments with aarch64 on Raspberry Pi)
by Mathieu Baudier 16 Dec '20

16 Dec '20

Hello, given the recent change in direction of CentOS, what will become of the AltArch repositories? (like CentOS 7 aarch64 and the related kernel repositories) I have been experimenting (with some success) with running a regular CentOS 8 aarch64 (ARM 64 bits) on a Raspberry PI 4 (with 4GB RAM), using the aarch64 kernel-rpi2 provided by CentOS 7 AltArch [1]. (a few more technical details below) This is a very different question than what is currently hotly discussed on this list, with the end of the bug-for-bug clone of RHEL, as there were never expectations that such settings would be supported. But on the other hand, I liked to use CentOS for innovation in a given field (mostly Java related) as its stability allowed one to go deep into one direction with "other things being equal" (contrary to Fedora, which is always moving in all directions). I guess that all these "side projects" (and SIGs, etc.) will disappear as well, won't they? Cheers, Mathieu ## More details about running CentOS aarch64 on a Raspberry Pi 4 As for my experiments with running CentOS 8 on a Raspberry Pi 4, a bit more details, so that these efforts are not completely lost. Two approaches were working : - From a plain CentOS 7 AltArch aarch64 installation, perform a CentOS 8 aarch64 install in a chroot (with the --installroot option) + a clean kernel-pi2 install from the CentOS 7 kernel-pi2 repository. Then copy the chroot to an .img file, and use this image to initialise an SD card. - From a plain CentOS 7 AltArch aarch64 installation, perform an in-place upgrade to CentOS 8 (first install dnf from EPEL, then switch the repos, and it works) The second approach had better device support on the Raspberry Pi 4 (most importantly the wifi, which was not working with the first approach), but this was probably a matter of subtle kernel / modprobe configs that were beyond my skills. I thought that I would share all this at some point, and ask for help from the CentOS AltArch developers; but I guess it is irrelevant right now. Both approaches were working equally well on the Raspberry Pi 3 (but Fedora support is good for this version, while Raspberry Pi 4 is not supported, so I tend to use Fedora aarch64 on them). As for what is actually the point of doing all this, this is not for weekend hobby tinkering, and it is relevant for server-side applications. ARM 64 bits is becoming an important platform (hence the fact that RHEL is now supporting it, MacOS will soon completely move to it, etc.) especially if one is interested in climate-friendly low-power IT, also on the server-side. But finding hardware is not easy and the (cheap) Raspberry Pi have 64-bit capable processors, even though the default distrib (Raspbian, based on Debian) does not yet support 64 bits (but they are working on it [2]). After trying many distributions, a paradox was that CentOS was actually the easiest to deploy and use in order to get some results (thanks to the work of the AltArch team!) In my case, the main interest was to test on ARM 64 bits GraalVM, the next generation Java platform, which can compile Java (and other programming languages) to native code. These builds require a lot of memory, but with an extremely slimmed down CentOS 8 and the 4 GB memory of the Raspberry Pi 4, it worked! [3] On a different layer, I could also test Eclipse SWT (Java user interface library) on this architecture (but on the plain CentOS 7 aarch64 with GNOME), and provide some quick feedback to Eclipse developers on their recent support for the whole Eclipse IDE on ARM 64 bits.

Blog article: CentOS is NOT dead
by Nicolas Kovacs 16 Dec '20

16 Dec '20

Hi, Here's an interesting read which makes a point for CentOS Stream: https://freedomben.medium.com/centos-is-not-dead-please-stop-saying-it-is-a… tl;dr: Communication about Stream was BAD, but Stream itself might be a good thing. Here's why.

Status of DLM in CentOS?
by Michael Schwartzkopff 16 Dec '20

16 Dec '20

Hi, I was searching for DLM for my Centos 8. But it seems there are no packages available. I already enabled the HA repo. But no success. Now I changed to centos stream, but still no package available. How is centos going to ensure correct locking in a shared storage environment? Any help appreciated.

On-demand audio streaming software
by Nicolas Kovacs 16 Dec '20

16 Dec '20

Hi, Since 2006 I had a streaming audio server based on Icecast and MPD running on CentOS. It works like a little webradio, e.g. listeners connect to a live stream with VLC, Audacious or any other client capable of this. I wonder if there's some software that can stream on-demand audio like music playlists or podcasts. What I'd like to do is host a series of playlists (like "Radio Show of the week") or podcasts, and then someone who wants to listen to it clicks on it and can listen to it from start to end. Any suggestions?

DLM in CentOS?
by Michael Schwartzkopff 16 Dec '20

16 Dec '20

Hi, about one week ago I asked about the status of the distributed lock manager DLM in CentoOS. I could could not find it in any repositories. I also got no answer on my mail to this list. So any answer to my question?
