Linux add swap space file
To add swap space for Linux, you'll need to add either a swap partition or create a new (big) file and use it for swap: To add a new 1GB file I do this: root@debian> mkdir /swap dd if=/dev/zero of=/swap/swapfile_1gb bs=1024 count=1048576 mkswap /swap/swapfile_1gb swapon /swap/swapfile_1gb To enable the swap file for the next boot, edit /etc/fstab and add this: /swapfile swap swap defaults 0 0 To check that the swap file is used, type: swapon -s free That's it! bs: blocksize count: number of blocks 1 million blocks x 1K = 1G
