The Btrfs file system has certain caveats about swap files. There are two points we’d like to discuss quickly. Let’s look at the easy way to add some swap space. Without any swap, sane memory management becomes very difficult for the kernel to achieve. It’s an important part of a well functioning system.

Swap isn’t just used as a means to free up RAM when you’re running low on memory. In fact, some Linux distributions now default to creating swap files rather than swap partitions.
That’s no longer the case with improvements in the performance of mechanical (spinning) hard drives and more efficiency in the swap functions within the Linux operating system. A swap file will work in tandem with any existing swap you may have, whether that is a swap file or a swap partition.Īt one time, there was a performance hit for using a swap file compared to a swap partition. This is a special file, pre-allocated and reserved for use as swap space.
The simple solution to all of these is to add a swap file to your computer. Sometimes you inherit the administration of a system that has no swap, for reasons you’ll never be able to discover.Maybe you previously decided that you had so much random access memory (RAM) you didn’t need any swap, and you’ve changed your mind.It’s easy to click the wrong option during the installation process and to decline adding swap to your system inadvertently.Perhaps your swap space is frequently running at maximum or close to maximum.There are several scenarios where you might want to increase existing or add new swap space to your Linux computer.
