I am trying to create a swapfile on my fedora 35 system and do not know what I am doing wrong: trash>uname -a Linux fedora 5.16.15-201.fc35.x86_64 #1 SMP PREEMPT Thu Mar 17 05:45:13 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Why do you need to create a swapfile? Such details are normally handled
by the installer in a way that works for the majority of users. Is your F35 a fresh install or upgrade?
If I follow the swapfile instructions on
https://docs.fedoraproject.org/en-US/Fedora/14/html/Storage_Administration_G...
It is unwise to apply Fedora 14 documentation on Fedora 35 -- a lot has changed. Are you using the default brtfs filesystem? On my F35 system with btrfs (and 16GB RAM):
% swapon -s Filename Type Size Used Priority /dev/zram0 partition 8388604 30208 100
