Hello,
I wanted to make a swapfile, but I have run into a problem with it.
Here is my shell "log":
[host /]# fallocate -l 2G /swapfile
[host /]# chmod 600 swapfile
[host /]# mkswap /swapfile
Setting up swapspace version 1, size = 2 GiB (2147479552 bytes)
no label, UUID=e19bca21-75ec-428a-b3f8-8dd847b2a76a
[host /]# swapon -v /swapfile
swapon: /swapfile: found signature [pagesize=4096, signature=swap]
swapon: /swapfile: pagesize=4096, swapsize=2147483648, devsize=2147483648
swapon /swapfile
swapon: /swapfile: swapon failed: Invalid argument
[host /]# swapon -a
[host /]# swapon --show
[host /]# free
total used free shared buff/cache available
Mem: 16066972 5558368 5481120 1800276 7168064 10508604
Swap: 0 0 0
Do any of you know why this is happening?
What filesystem is your / ? For btrfs there's another approach: https://wiki.archlinux.org/title/Btrfs#Swap_file
