Swap Partition

[geecee]

When I open System Settings -> Advanced -> Disk & File Systems the swap partition is shown as disabled. When I try to enable it I get the following error message:

An error occurred while enabling swap partition a5c9e60b-f319-44d0-a68f-ccdee617d5e2.
The system reported: swapon: cannot stat a5c9e60b-f319-44d0-a68f-ccdee617d5e2: No such file or directory

The machine is otherwise working ok. Does anyone know what's going on?

Re: Swap Partition

Check, is there problems with the swap (konsole):

dmesg | grep swap

or

grep swap /var/log/dmesg

Here it tells:

[ 44.207367] Adding 2048276k swap on /dev/sda3. Priority:-1 extents:1 across:2048276k

What do you have in the fstab (/etc/fstab)?

Here:

# swap
# /dev/sda3
/dev/sda3 none swap sw 0 0

Commands:

man mkswap

MKSWAP(8) Linux Programmer’s Manual MKSWAP(8)

NAME
mkswap - set up a Linux swap area

SYNOPSIS
mkswap [-c] [-vN] [-f] [-p PSZ] [-L label] device [size]

DESCRIPTION
mkswap sets up a Linux swap area on a device or in a file.

(After creating the swap area, you need the swapon command to start
using it. Usually swap areas are listed in /etc/fstab so that they can
be taken into use at boot time by a swapon -a command in some boot
script.)

With my system:

sudo mkswap -c /dev/sda3

man swapon

DESCRIPTION

Re: Swap Partition

Thanks Rog131. With a combination of your help and the Swap Partition FAQ I managed to work it out. My swap partition is now enabled.
