How to add a swap file to Ubuntu

[lsk3993]

Didn't you say you have two swap partitions? How did you manage that when you said you couldn't shrink the NTFS partition? Here's what mine looks like. I also just realized my swap space is way to big.

Sorry, I think I may have confused you... I've attached screen shots of the /media folder and GParted

Did you do a full install or did you use Wubi?

I did a full install, I used Wubi before, but I wouldn't trust windows with my Ubuntu install

Ubuntu doesn't use swap files. It has to be in a separate partition. As you know you will not be able to create another partition outside of your Extended partition. You will have to create it within your Extended partition. By first shrinking the 288GB partition by 4GB.

Ok, I guess I read this wrong then: https://help.ubuntu.com/community/Sw...20more%20swap?
From what I understood, it says I can make a swap file
Ok, I'll make a swap partition then, and just delete the two files it left me in /media then?

The NTFS partition is mounted under /media/Shared. You have to edit the command accordingly:

sudo dd if=/dev/zero of=/media/Shared/4096Mb.swap bs=1M count=4096

The command is silent & it may take some time to complete. Be patient.

and you have to mount the NTFS partition at boot time:

& finally add this line to the fstab file:

/media/Shared/4096Mb.swap    none    swap    sw    0    0

Thank you, I wasn't really expecting the silent command- being used to windows and its stupid loading menus and fancy hourglasses

Also, what is an fstab file?

I stand corrected. I had never heard of people doing that.

It looks like the files was created, so I am guessing you need to do the next command in the line while making the line changes that you made for the system to look in the shared partition.

After the swap file is created you have to format it:

sudo mkswap /media/Shared/4096Mb.swap

and create an entry for it in the /etc/fstab file. To edit the file run:

gksudo gedit /etc/fstab

and copy/paste this

/media/Shared/4096Mb.swap    none    swap    sw    0    0

at the end of the file.

Thank you again, I am currently in a LiveCD session trying to find those two incorrectly made swap files that I need to delete but I can't seem to find them as /media appears to be empty.
How do I get to them from the Live CD?

[sisco311]

You don't need the Live CD to delete the files. Boot your Ubuntu installation use the rm command to delete the files:

sudo rm -i /mnt/512Mb.swap

and

sudo rm -i /media/shared4096Mb.swap

Be careful, the rm command is dangerous, make sure that you delete the files you want.
