I have a 27.8G swap partition; though I have no swap space, I'd like to change that.

Here is the pertinent output from top.

KiB Swap:  0 total,  0 free,  0 used

I believe I may have turned it off with the swapoff --all. That being said the swapon --all exits with swapon: /dev/sda6: swapon failed: Invalid argument.

Here is the swap entry in my /etc/fstab

# swap was on /dev/sdb6 during installation
UUID=aa0cdc90-ef01-446b-a6a2-fac368d16aca none swap defaults 0 0

I affirmed the UUID of my partition with the one in /etc/fstab. Below is the output from blkid.

sudo blkid /dev/sda6
/dev/sda6: UUID="aa0cdc90-ef01-446b-a6a2-fac368d16aca" TYPE="swap" PARTUUID="6ddd3267-3895-40e5-9acc-56bfbc58039b"

My swap partiton is on /dev/sda6 not /dev/sdb6. I presume /dev/sdb6 was the bootable USB I used to install the system. This is a dual-booted, single-drive system.

Thanks in advance for your help.

I think the swap space may have never been turned on since initialising the OS.

The problem was solved by running mkswap and then swapon on the partition.

Have you ever changed it? Maybe you didn't set your swap. Personally, I recommend you use Gparted to edit your swap again.

You can install Gparted in your terminal or I have written an answer here - How to install Gparted(iso). After that, the swap won't show up because it is not active.

Type:

sudo gedit /etc/fstab

add:

/swap/swapfile  swap      swap    defaults   0       0

reboot, and see if it is all right:

cat /proc/swaps
