How to increase or decrease swap

Question

How can I increase or decrease the swap on my server?

Answer

The swap size can be changed without rebooting the server using the create-swap script.

1. Turn off the swap space.

   swapoff -a

2. Edit /etc/fstab and comment out the swap line.

   #/usr/swpDSK swap swap defaults 0 

   Please note that multiple swap sources can exist. This step is only required if you're replacing the swap file generated by the create-swap script.
3. Run the create-swap script to resize the swap file. Please replace # with the size in Gigabytes that the new swap file should be.

   /usr/local/cpanel/bin/create-swap --size #G -v

To verify that the swap was resized correctly, use the free command.
