Help in increasing swap file size

Question

I have an existing virtual storage but it is not enough and I cannot find a solution to this problem. I want to increase my existing virtual memory size. Any help is appreciated.

Answer 1

Increase swapfile size to match RAM size

• Check the swap that is in use:

  sudo swapon -s
  

• If swap partition(s) are found:

  sudo swapoff -a
  sudo nano -Bw /etc/fstab
  

• Add # before the UUID of the swap partition(s):

  # UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX   none   swap    sw     0       0
  

• Add a line for the swapfile, if one does not exist:

  swapfile   none    swap     sw      0       0
  

• Create the swapfile:

  sudo fallocate -l XG /swapfile*
  

  where X is swapfile's size in GB:

  sudo mkswap /swapfile
  sudo chmod 0600 /swapfile
  sudo swapon /swapfile
  

• Reboot:

  sudo reboot
