how to fix (fallocate: fallocate failed: Text file busy) Ubuntu 22.04?

Asked by michael

While trying to change swap space size in Ubuntu 22.04, I get this error: fallocate: fallocate failed: Text file busy). I googled it, did not find answer. One answer gave steps on how to change swap space on 17.04, just what I was doing, when I got error. Any help will be appreciated.

I read on google that you must take swap file to 0 before you can increase the size to what you want. true of false?

You need to run:

sudo swapoff

So that swap isn't used, then resize. You can then reboot or run

sudo swapon

I suggest you close as many applications as possible as the stuff in swap will need to be shifted back into RAM
