i am new in garuda and btrfs and I also forgot to create a swap partition. The file system is encrypted with luks, so I don’t want to create a new partition but use a swap file instead.
sudo dd if=/dev/zero of=/swap/swapfile bs=1M count=32768
sudo chmod 600 /swap/swapfile
sudo mkswap /swap/swapfile
sudo swapon /swap/swapfile
swapon /swap/swapfile produces an error, “the argument is invalid”
I found the following warning in the log files:
Jan 24 21:30:47 hp kernel: BTRFS warning (device dm-0): swapfile must not be copy-on-write
How do I activate my swapfile in the btrfs file system?
