How to restore swap size after enable Hibernate
When using the hibernate feature, a swap space larger than the size of the memory is allocated on the disk to store the current state of the system during hibernation.
If you no longer need to use the hibernate feature and wish to release the swap space on the disk, you can execute the following commands.
hint: Change the swap space to the system's default 2GB.
Steps:
$ sudo swapoff /swapfile
$ sudo dd if=/dev/zero of=/swapfile bs=1M count=$((2 * 1000)) status=progress
$ sudo chmod 600 /swapfile
$ sudo mkswap /swapfile
$ sudo swapon /swapfile
