  • You've provided no OS/product/release details; and most of your provided commands relating to creating a file of specified size, but not actually telling your system to use it as a swapfile. You may, or may not have done that, but we can only know if we're told - currently we don't even know what OS/release you're using, nor what swap partition/swapfile setup is expected. – guiverc Aug 03 '22 at 07:42

  • How much RAM? And why do you need more swap? Typically with new systems, swap is never used as you have enough RAM to run everything. Note that apps are cached in RAM, so RAM may fill but not really fully used. what does free -h show? – oldfred Aug 03 '22 at 13:36
