How to delete a swap file?

  • Posted May 26, 2014

I was trying to delete the swapfile on a digital ocean virtual server using the instructions given here:

However, when I type:

sudo rm /swapfile

I get the following error:

rm: cannot remove `swapfile': Operation not permitted

I have changed the permissions on the swap file to 777 and I believe I have root privileges. I still cannot delete it. It may be helpful to know that I created this instance of a server from an image of another server that I had configures. The swap was enabled in that original server.

How do I delete this file?

Thank you.

Try first: “swapoff /swapfile”

Thank you, Jerzy. I am almost certain that I had run swapoff /swapfile. <br>Anyhow, I did it again and this time it worked. <br> <br>Thanks again.

Except of all answers provided here, you might also need to restart your Ubuntu

You maybe missing an entry in /etc/fstab and turn on the swap somewhere else. <br> <br>Therefore sudo swapoff -a -v take no effect. <br> <br>If that’s the case, check init scripts and remove the swapon script. <br> <br>The following command may helps. <br> <br>~~~~ <br>grep -r “swapon” /etc/init* <br>grep -r “swapon” /etc/rc* <br>~~~~
