suspend to disk not working due to swap space failure

suspend to disk not working due to swap space failure

[rasmit.ranjan]

Hi all,
    In my laptop, suspend to disk was working properly.But after so many
days I tried it today.But it failed. First time i tried it showed " Not
enough space, Error -12 suspending".But i tried once more. Then it
failed  showing "error: can not find swap device, try swapon -a ".This
seems my swap partition is not active. So I tried "swapon -a" but it did
not work. Also the output of "swapon -s " shows nothing. I tried "cat
/proc/swaps" but this shows nothing as well. So i tried creating a new
swap space by the command " mkswap". But still my swap partition does
not come up. I reboot my system but that did not work as well. What
might be the problem? 
My laptop has RAM of 256 MB and swap space is 1 GB and I am using kernel
2.6.15.4.
 
Thanks,
Rasmit.

The header of your swap partition got lost.  Please try
"mkswap <your_swap_partition_name>" and then swapon -a.  If it works, the
suspend should work either.

Is it listed in /etc/fstab so swapon -a can find it?

I tried doing this as wel. But it didn't work. Actually my /etc/fstab
file doesn't show any entry for swap partition.

No it is not listed in /etc/fstab file. But `fdisk -l` shows the swap
partition.

OK

What's the name of your swap partition and how does your /etc/fstab look like?

So your swap is supposed to be /dev/hda5.  Please do

# mkswap /dev/hda5

[BTW, you could create the swap as a primary partition too.]

Please add the following line to your /etc/fstab:

/dev/hda5	swap	swap	defaults	0 0

Then (assuming you have run mkswap already) please do

# swapon -a

and check if it shows up in /proc/swaps .

Greetings,
Rafael
