The assigned swap memory can be disabled by using swapoff command. You can list all currently mounted and active swap partition by a following linux command:
# cat /proc/swaps Filename Type Size Used Priority /dev/sda6 partition 2047996 0 -1 /swap file 104857596 0 -2
From the above output we can see the type of swap used, relevant file and size. The size should match the swap size output of the free or top command:
# free | grep Swap Swap: 106905592
To disable all active swaps use -a option with swapoff:
# swapoff -a
The above will disable all active swaps found at /proc/swaps. It is also possible to disable each swap memory separately using swap file name. For example the below command will disable swap memory with a filename/swap:
# swapoff /swap
