Hey all,

I've just noticed that my linux didn't load up my swap space anymore, so I checked in the logs and found this:

...
EXT3 FS on hda3, internal journal
drivers/usb/input/hid-ff.c: hid_ff_init could not find initializer
input: USB HID v1.10 Mouse [Microsoft Microsoft 3-Button Mouse with IntelliEye(TM)] on usb-0000:00:1d.0-1
drivers/usb/core/usb.c: registered new driver hid
drivers/usb/input/hid-core.c: v2.0:USB HID core driver
Unable to find swap-space signature
kjournald starting. Commit interval 5 seconds
EXT3 FS on hda2, internal journal
EXT3-fs: mounted filesystem with ordered data mode.
Unable to find swap-space signature
...

I don't know when this happened, but I have a pretty good idea it was when I tried out suspend to disk for the first time. It didn't work and Linux rebooted up saying I made an unclean shutdown.

This is how my 40GB HD is set up:
hda1 - NTFS
hda2 - /boot
hda3 - /
hda5 - logical 1 - swap
hda6 - logical 2 - fat32 (for sharing files with linux and XP)

The output from df is the following:
[root@localhost root]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda3 10321168 5992588 3804296 62% /
/dev/hda2 99075 10946 83014 12% /boot
none 241440 0 241440 0% /dev/shm
/dev/hda6 4019272 659908 3359364 17% /mnt/windows

The swap partition (hda5) is still there but somehow it's not getting accessed. Any help on how to fix this problem would be very welcome.

I'm running Fedora Core 2 Test 1, with kernel 2.6.4, kde 3.1.95-0.3 on a Toshiba TE2300 laptop.

A swap partition isn't mounted like a regular filesystem. Check the output of the free command. What does it say for total swap? If zero then something is awry. You can try reformatting the swap partition:
mkswap /dev/hda5
to mount
swapon /dev/hda5

Hi Michaelk,

this is my output from free:

[root@localhost root]# free
total used free shared buffers cached
Mem: 482884 462708 20176 0 98820 68256
-/+ buffers/cache: 295632 187252
Swap: 0 0 0

I take it this isn't good since swap is showing 0 across the board.

So, to reformat swap, do I do:
1. mkswap /dev/hda5
2. mount swapon /dev/hda5

Sorry my fault... your enabling swap not mounting. The command is just:
swapon /dev/hda5

You will have to to do mkswap /dev/hda5 and then do swapon /dev/hda5. Check in your /etc/fstab file for any incorrect swap lines.

This is what's in my fstab file:

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/hda5 swap swap defaults 0 0
...

I don't think there's anything wrong with the swap mounting is there?

I ran the mkswap /dev/hda5 and swapon /dev/hda5 commands and now have a swap space. Do I need to do this everytime I reboot linux?

No, swap will be automatically enabled via the line in your /etc/fstab file at boot time.
