Mounting device using UUID by non-root

2021-03-24 Thread Geoffrey Leach
Suppose I have a USB stick with UUID 1234. I am able to mount it as root # mount UUID=1234 /Media or as a non-root user % sudo mount UUID=1234 /Media unsafe! Question: is there any way to perform the mount (from the command line) without the sudo? Thanks.

BTRFS settings for media storage

2021-03-24 Thread Richard Shaw
I've been running MythTV for about 10 years now and I've finally outgrown my media storage, currently a single 4TB disk drive. I have purchased 3 additional drives of the same model and plan to put them into a BTRFS RAID1 array. Setting nodatacow on the media directories is a no-brainer, but what

Hi, I have a Toshiba satellite pro (R50-B-109) and since I updated to kernel 5.11.17 the fan runs constantly even if sensors report Temps around 35C. If I load the previous Kernel 5.10.21 fans are silent and Temp is around 40C. What changed? I have no control over the fans as pwmconfig cannot

With Fedora being intended as a desktop platform, why are these settings not the default? The highest priority for a desktop system is to keep the user experience flowing smoothly, not to maximize disk i/o rates. Can this be fixed in time for F34?  Do we need a bug report? On 3/23/21 2:26
