Hi,
i am wondering why the swap volume is by default just 980M.
Since I like to let my laptop hibernate when I am not using it, the standard swap volume size is too small.
I fixed it by resizing the root and swap volumes and adding the UUID from the swap volume to the grub CMDLINE.
Swap is a handy fallback and it is very easy to adjust.
However, it is unwise, generally, to have swap file be significantly larger than the RAM you have available. Personally, I prefer to go by half.
Given that there are Minimum System Requirements; default swap would be small compared to those operating at much higher than the Minimum RAM requirements.
I'm also using LUKS and looking to expand my swap at the moment, just letting the team know I'm another user looking for a larger swap.
I'm a heavy power-user and can have a lot open, so occasionally I'm filling my 32GB of RAM and after a few painful OOM's and having to hard reset my system I see that my default swap is setup to be 1GB.
I think I may be assigning a 32GB or more swap file in a few minutes and manually adjusting the swapiness value to favour using RAM even more strongly than it does at present. The swap for me will just be fail-safe to avoid locking up or crashing, I don't care if the performance goes slow as long as it is stable.
