How to resize Swap file

Resize Swap file size

Resize Swap to 8GB

• Turn swap off
  This moves stuff in swap to the main memory and might take several minutes

sudo swapoff -a

• Create an empty swapfile
• Note that "1G" is basically just the unit and count is an integer.
  Together, they define the size. In this case 8GB.

sudo dd if=/dev/zero of=/swapfile bs=1G count=8

sudo mkswap /swapfile  # Set up a Linux swap area
sudo swapon /swapfile  # Turn the swap on

• Check if it worked

grep Swap /proc/meminfo

GUI method for increasing the size of swap partition

sudo apt-get update
sudo apt-get install gparted && sudo gparted
