[CentOS] CentOS 8 partiitioning for reliability
I was just given a Dell R720xd with 160 GB memory and 12x 900 GB drives that I plan to deploy as my home mail/file/backup server to replace an aging Supermicro server running CentOS 7. Yeah, it's gross overkill for that and I expect to tuck most of the drives away for spares. How should I RAID and partition this beast for maximum reliability? My current C7 system is using 1 TB of 2 TB capacity on the root partition (4x 1 TB drives in RAID 10). /boot is 300MB/50GB. Memory and swap is 8GB each. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] some questions about tuned ...
Hi, what is the point of running tuned as a daemon when dynamic tuning is disabled? What is the point of enabling dynamic tuning, especially when using the supplied profiles like throughput-performance? I haven't customized those by specifying any thresholds, and I don't see any point in doing things like dynamically changing disk schedulers or CPU governors depending on something recognized by tuned. Why is there no measurable difference in power consumption between using the powersave, throughput-performance and virtual-host profiles but a very noticeable difference in performance? The difference in performance appears to depend mainly on which CPU governor is used. For example, you can make a customized profile from throughput-performance that uses the powersave governor, and performance will be very much as if using the powersave profile. Since there is no measurable difference in power consumption, why would I want to use profiles and/or CPU governors that supposedly save power and decrease performance? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I use MATE on C7, because Gnome is, how do I say this politely..., um, horrible. Not a KDE fan either. Gnome-2.x wasn't broken, didn't need to be thrown away and replaced by something completely different. Not broken, but full of bugs that will never get fixed. I keep seeing posts about alternative desktops - great, just another of the things that make linux the OS of choice - you have choice; even about which desktop management system you wish to use. I have not tried mate for a number of years, it was quite simple and basic to use, but also lacked some of the polish we see in the market place, I have tried KDE and usually just use gnome, at whatever iteration RH and CentOS put out. KDE out of the box a year or so ago caused me some major grief to do with files and indexes and loosing disk space, so I walked away. Gnome has not been kind to developers like myself, and those trying to do real work with their work-stations - things that once were easy have become more difficult, however I have found solutions to most of the problems the later releases have introduced. Why bring this up? Well I guess I agree with some of the sentiment expressed often by a regular group of list contributors, but I also find it going stale. Change in the IT world is a constant. Not all of it is progress, in the sense of getting closer to a particular goal. However, it must be recognised that there are many, many different goals out there, and many of those will not be convergent, thus some gain, others loose. So at the end of the day, we make our choice, and live with the consequences. I am looking forward to spinning up CentOS 8 in the next month or two and seeing what that works like for my particular mix of tasks. It seems RH has chosen to support gnome desktop, thus for better or worse, that's where I'll go too. CentOS has far too many other benefits for me to go elsewhere. HUGE thanks to all the CentOS team and those that offer their experience to help and assist others - it makes my computing world function more or less reliably and deterministically, and all under my ability to observe and use. Thanks for reading, please forgive my slightly off topic rant. Rob I did a while back rebuild the EPEL rpms for 1.20. There are spec files I could make available but I can't find the build environemnt setup now. It involves mock, a custom local repo to receive the fresh builds as you don't want to pull in the rpms from EPEL, and a build script that defines the order, among other things. If I have time next week I can try and locate everything. If Mate won't be (or may not be?) supported by EPEL, has anyone looked at similar alternatives? I came across 'Cinnamon' (which is available from EPEL) - does anyone have experience of Cinnamon (good/bad/otherwise) ?
