Forgot to create Swap Partition

[sohaibk]

Hi there,

I have installed linux but I forgot create swap partition on it.

I have a following partition :
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 131G 50G 75G 40% /
none 7.9G 188K 7.9G 1% /dev
none 7.9G 0 7.9G 0% /dev/shm
none 7.9G 36K 7.9G 1% /var/run
none 7.9G 0 7.9G 0% /var/lock
none 7.9G 0 7.9G 0% /lib/init/rw
/dev/sda1 461M 30M 409M 7% /boot
/dev/sda5 276G 223G 39G 86% /var
/dev/sda7 131G 188M 124G 1% /usr

I want to take some space from /usr and create swap partition, is there any way I ca do this? or if there is any other way please let me know.

Thank is advance.

Regards,

Sohiab Khan

It is possible to use a file instead of a partition as swap, with no performance penalty.

Hello and welcome!

Are you sure you need one?

If you have plenty of RAM, you might be fine going forward without a swap partition. I've not used one in the last 4 or 5 years and haven't had any issues, but I do have plenty of RAM on hand.

How much RAM do you have? Post the output of free command here.

free

If you have at least 1.5 GB of RAM your ok (Depending on the Linux Distro your running)
Ubuntu, Debian, Fedora, RedHat, Mint, SuSe 2 GB and your ok
The Rest 'Mostly' Will Run on a GB of RAM without Swap ok

If your computer is having a Hard Time Processing Then you need to setup a Swap Partition :P

PS : Having a Dual Core Processor Helps

Having a swap file isn't necessary if you have an abundance of RAM. The swap file works simular to how microsoft has Virtual RAM, they act like memory dumps when your physical RAM becomes maxed out. If you plan on making a swap file; common practice is to make the swap half of what your physical RAM is.
