To determine if a swap file already exists, issue the command:
cat /proc/swaps
------------------------------------------------------------------------------------------------
In the following example, we’ll extend the swap space available in the /swapfile to 2GB.
You can do "df" command, and see if you have enough free space first under / (root) directory.
To change the size of the swap partition (file):
- Turn off all swap processes
|
|
sudo swapoff -a |
- Resize the swap
|
|
sudo dd if=/dev/zero of=/swapfile bs=1M count=2000 |
if = input file
of = output file
bs = block size
count = multiplier of blocks
- Make the file usable as swap
|
|
sudo mkswap /swapfile |
- Activate the swap file
|
|
sudo swapon /swapfile |
- Check the amount of swap available
|
|
grep SwapTotal /proc/meminfo |
