Dynamically growing swap file on Debian

I know how to create a swap file and use it as swap. But I have to configure the size of the file beforehand and the space is used on the disk, if the swap is used or not.



How do I create a swap that has an initial size of 0 and grows on demand?

    It's better to avoid useless words, especially at the start of the title which is where people pay the most attention. See How do I write a good title?. “Dynamically growing swap” gives the essential idea. “How do I create” doesn't begin to indicate what the question is about. There are people who prefer to make question titles questions because they're questions, but it's silly reason: the title is also the title of the answers.

SwapSpace is a utility that creates a ‘dynamic swap file’ which according to the requirements of the operating system changes its size.



So you can even forget about creating a virtual swap file and just install “SwapSpace” and it’ll automatically create one for you and will even resize it when necessary.



You can also use ‘Swapspace’ side by side with a manually created swap file and when the manually one gets filled ‘Swapspace’ will automatically create another one for the OS so the OS will always have a swap space and it enhances the stability.



Another useful thing about “SwapSpace” is that, whenever it can, it’ll reduce the size of the SwapSpace and “release” those bytes into user file system and according to the developers this reduction helps to increase the swap file’s performance as well (plus your “precious” HDD space is not wasted too).



Install with



sudo apt-get install swapspace


And adjust the config file to your needs. I set the minimum to 0 on my VM debian machine with just 8GB HDD




Additionally I also set the swappiness to 0 to minimize the usage of the precious HDD space on my VM:



To change the system swappiness value, open /etc/sysctl.conf as root. Then, change or add this line to the file:



vm.swappiness = 0


(Reboot for the change to take effect)

Afaik, any swap partition that you would make using fdisk for example, would need any space greater than 0, as you are modifying the space from an existing disk and reallocating it into somewhere else.



Anyway, and answering your question, you can easily make a small partition, assign it as swap under fdisk, and afterwards:



1) disable swapping with swapoff -v
2) resize partition with lvresize
3) format the partition with mkswap
4) re-enable the swap space with swapon -v



Afterwards, you can use cat /proc/swaps to check if it has been upgraded or not. You can easily use this on a script, depending on your system specs, and run it on demand for whenever you need to increase that swap space. Something like:



$ swapoff -v /dev/swapvol1
$ lvresize /dev/swapvol1 -L +1G
$ mkswap /dev/swapvol1
$ swapon -v /dev/swapvol1

Swapspace is old and unmaintained and could lead, one day, to problems in modern systems. I think that the best solution for dynamic swap is to:



sudo apt install dphys-swapfile
sudo update-rc.d dphys-swapfile enable


then setting CONF_SWAPFACTOR=2 in /etc/dphys-swapfile and finally



sudo service dphys-swapfile start

    • This doesn't answer the question because the swap size is changed manually, not on demand. Furthermore, resizing the LV isn't useful: where do you find the space to grow? how is the freed space on shrinking not wasted? The question asks about a swap file, which solves the issue of the free space — it's available for other files.

    • Changing the swap size on demand is a good idea, but swapspace does not cover the scenario of swsusp being used for supporting hibernation. I believe this answer might be more sane for those users who need hibernation support. Until swapspace handles that better, of course.

    Swapspace is old and unmaintained and could lead, one day, to problems in modern systems. I think that the best solution for dynamic swap is to:



    sudo apt install dphys-swapfile
    sudo update-rc.d dphys-swapfile enable


    then setting CONF_SWAPFACTOR=2 in /etc/dphys-swapfile and finally



    sudo service dphys-swapfile start
