RAID controller recommendations that are supported by RHEL/CentOS 8?
by Dennis Jacobfeuerborn 11 Oct '19

11 Oct '19

Hi, I'm currently looking for a RAID controller with BBU/CacheVault and while LSI MegaRaid controllers worked well in the past apparently they are no longer supported in RHEL 8: https://access.redhat.com/discussions/3722151 Does anybody have recommendations for for hardware controllers with cache that should work in both CentOS 7 and 8 out of the box? Regards, Dennis

CentOS 8 Installation Not Recognizing Local Disk
by Brewer, Mitchell 10 Oct '19

10 Oct '19

I have an older Dell PowerEdge server with one hard drive, with CentOS 7 currently installed. I wanted to do a clean install of CentOS 8, but it doesn't pick up the hard drive. When I click on the destination to pick the hard drive it only shows the USB drive that I'm installing from. I checked for a RAID configuration on the server, but there is only one disk, and no RAID is configured. The disk is controlled by the PowerEdge Raid Controller (PERC), but when I disable that I lose the disk completely. I suspect that PERC is part of the problem, but a CentOS 7 install proceeds normally with PERC enabled. Do you know of a change from CentOS 7 to 8 that would cause this, or if there is a workaround? I've searched for several days and haven't found anything yet. Thank you!

It seems that glances is not in EPEL for CentOS 8. Is that coming at some point, or has it been deprecated in favor of some other tool?

CentOS for musicians?
by wwp 08 Oct '19

08 Oct '19

Hello, still searching but didn't find very precise answers yet, is there a computer-aided musical creation -oriented flavor of CentOS (like the Ubuntu Studio)? Or would it be about gathering stuff from different repos and setting up everything by hand? A repository that would provide low-latency kernel (realtime one?): I've found the CentOS-RT from the CERN + (1)). Specific tools (from Jack/qjackctl, carla, audacity .. to the DAW), I've found stuff on different repositories. On a CentOS7 box I could setup jackd, audacity/lmms (from the sources) and reaper (ardour from nux depo is way to old), I know what to use at end-user software but would like to find a CentOS variant/repo where software is recent (sometimes critical for audio devices). Any advice? (1) https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux_for_… Regards, -- wwp https://useplaintext.email/
