Activate hibernation on crypto BTRFS

Hi everyone.
I would like to be able to use the hibernation on my system, an old MacBook Pro with crypted btrfs filesystem.

I use Grub as a bootloader and I calculated Uuid and offset following Archlinux’s wiki.


sudo findmnt -no UUID -T /swapfile


sudo btrfs inspect-internal map-swapfile -r /swapfile

I activated the resume in Dracut

cat /etc/dracut.conf.d/resume.conf
add_dracutmodules+=" resume "

And I updated Grub and Dracut

sudo update-grub
sudo dracut-rebuild

I restarted the notebook but the hibernation still does not work, it gives me back error for the exhausted space on the device.

When i run systemctl hibernate I get this

Call to Hibernate failed: Not enough suitable swap space for hibernation available on compatible block devices and file systems

Where did I go wrong?

Sorry, my bad!

The correct swap file was located in /swap/swapfile but I mistakenly used an old /swap file that I should have deleted.
