What, exactly, is the Unbreakable Enterprise Kernel? RHEL/Centos 8 has kernel version 4.18. The current Fedora kernel is 5.8. The current kernel listed on the main page of kernel.org is 5.10. Where does UEK 5.14.x fit in here? Is it a fixed/enhanced/customized version of the current kernel on kernel.org, is it something to do with Fedora, or is it something entirely different and unrelated that runs on Oracle's own versioning scheme? And on that note, what does UEK do for you that the standard RHEL kernel doesn't? Would the average schmoe like me actually gain anything by running UEK over the standard Redhat kernel if I'm not running stuff like the Oracle database? Oracle UEK kernel is newer (based on 5.4.17 I think), probably support more hardware. Also, Oracle UEK kernel supports BTRFS filesystem, that Redhat don't even allow you to use it. I use UEK because this. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] https://blog.centos.org/2020/12/future-is-centos-stream/
I am already using Oracle Linux in some servers. Free as CentOS, faster updates than CentOS, and with some extra support, BTRFS and a newer kernel, for example.

Re: [CentOS] printer frustrations
I'm too having problems with my "HP Deskjet 2050" and CentOS 8, connected via USB. The same system with Debian 10 and CentOS 7 all works and print as normal, but CentOS 8 can't print. I don't really know where to look for this. Thanks. On 11/25/19 12:38 PM, mark wrote: I've got an old HP LaserJet 1018. It's a winprinter.

I'm curious, is there anything in RHEL 8 that would replace BTRFS or ZFS? I'm experimenting with BTRFS on one system and the snapshot and subvolume features are nice. I assume Stratis is the general answer. It looks like built-in RAID didn’t land in this version, which means we’re another 3-5 years from anything that actually works like ZFS or btrfs which are LVM + RAID + filesystem. According to the docs, you have to lay Stratis over MDRAID in EL8 to get storage redundancy: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/managing_file_systems/managing-layered-local-storage-with-stratis_managing-file-systems Snapshots with Stratis appear to work more sanely than in LVM2, so that’s something, at least. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos I really want to upgrade to RHEL/Centos 8, but I need to keep using my btrfs disk/partitions.

Re: [CentOS] Convert bare partition to RAID1 / mdadm?
You can also try this: 1- Convert your ext4 partition to btrfs. 2- Make raid1 with btrfs. With btrfs you can convert a bare partition to almost any raid level, with the proper hard disk amount. So... is it possible to convert an EXT4 partition to a RAID1 partition without having to copy the files over? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Math?
Try OCTAVE: http://www.gnu.org/software/octave/ I'm not sure it is the same thing, but maybe also works for you. Julio.
