| | 71 | == Adding a swapfile == |
| | 72 | If you have a live system which you need to give extra swapspace too without a reboot, then can add a swapfile. |
| | 73 | |
| | 74 | Note that a swapfile is much slower than a swap partition, which is -of course- slower than memory. The reason for this is to save the ship when the boat's going down, not increase preformance. |

| | 76 | Create file: |
| | 77 | {{{ |
| | 78 | dd if=/dev/zero of=/swapfile count=[size of swap, in 512B blocks] |
| | 79 | }}} |
| | 80 | Format it: |
| | 81 | {{{ |
| | 82 | mkswap /swapfile -p 16384 |
| | 83 | }}} |
| | 84 | Tell the kernel to use it at an lower priority (i.e. only use when swap parition is full): |
| | 85 | {{{ |
| | 86 | swapon -p 16384 /swapfile |
| | 87 | }}} |
| | 88 | |
