Flushing the swap

Flushing the swap

[Hal Nine]

Is there any way of making linux flush out all pages out of swap
space?  I want to have 0K of used swap space.

Not to be fecicious, you can reboot.

But if this is not good enough, you can try this:

swapoff -a
swapon -a

This may take a while if your system is busy and a lot of RAM has been used.
It especially will take a long time if your system was dipping into swap because an active process really needed that extra ram.

You can kill off as many memory hungry processes as possible first, to try and do this as painlessly as possible.

My thought is this: if she wants swap, give her swap! It beats a diamond ring.

as about 314 people already said 'swapoff -a' will work, but more to
the point is you probably don't want 0K of swap

What for? If they don't fit into RAM (likely, as swap is essentially "RAM
overflow"), you are toast anyway.

You might try swapoff(8)...

Maybe?

# swapoff -a
# swapon -a
