Hello Kenneth,

if you have a empty blockdevice, you can format it with mkswap, for example:

mkswap /dev/sdb3

With swapon /dev/sdb3 you can add this new formatted swapspace on the fly to you system. With an entry for this swapdevice you can mount it on every boot. Simply add the following line to you /etc/fstab:

/dev/sdb3 swap swap defaults 0 0

If you have no blockdevice, you can use a file as well:

dd if=/dev/zero of=/tmp/swapfile bs=1M count=1024

With this command you create a file with a size of 1 GB.

After that you do the same as above described:

mkswap /tmp/swapfile
swapon /tmp/swapfile

If you wish to mount this swapfile on every boot, put an entry in the /etc/fstab:

/tmp/swapfile swap swap defaults 0 0

You can check the success of your work with swapon -s.

Kind regards,
Patrick
