Hey,
during the installation of my full encrypted Ubuntu 20.04 a configured a swap space of 20G (because of using hibernate). Hibernation works two weeks ago. Now the swap space has size of 1G, but the logical volume has still a size of 20 G. What went wrong?
Here some outputs:
Code:
# free -h && swapon --show && lsblk && vgdisplay && lvdisplay && blkid && cat /etc/fstab

And sorry for crossposting. I have asked the same in askubuntu three weeks ago, but no one answered.
