This is needed when the physical memory is running out, or when pages initially created by a program are not needed any more. There are two types of swap space: swap partition and swap file.<br /> <br /> == Swap Partition ==<br /> TODO<br /> <br /> == Swap File ==<br /> More flexible than swap partition and well supported today. May not be the best choice on old fragmented hard disk though.<br /> === Setup ===<br /> * As root, create the swap file:<br /> fallocate -l 4G /swapfile<br /> chmod 600 /swapfile<br /> mkswap /swapfile<br /> * Activate the swap file:<br /> swapon /swapfile<br /> * Optionally make it available when system starts, in /etc/fstab, add:<br /> /swapfile none swap defaults 0 0<br /> * If you need to delete it:<br /> swapoff -a<br /> rm /swapfile<br /> <br /> === Server specific things ===<br /> Scaleway provides a script that does exactly above, with the exception of adding the swap file to the fstab. The script can be used like this:<br /> /usr/local/sbin/scw-swapfile start # create and activate a 4GB swap file in /swapfile<br /> /usr/local/sbin/scw-swapfile stop # de=activate and delete /swapfile</div>
