How can I use a swap partition instead of a swap file

  • 772

I have a swap file in my file system /swapfile with 2GB, but I want to use a partition.

I created a partition using Gparted.
I removed my swap file using: sudo swapoff /swapfile
But I have a line on /etc/fstab with my old swapfile.
** I Need To Inform My Ubuntu That I'm Using A Swap Partition. **

How can I achieve this?

    I found a solution:

    First find the UUID of the swap partition:
    sudo blkid | grep 'TYPE="swap"'

    Then modify your /etc/fstab and replace /swapfile with UUID=xxx, using the UUID you got from the command above. The line that now has /swapfile must then look something like

    UUID=01234567-89ab-cdef-0123-456789abcdef none swap sw 0 0

    The swap partition will be used after a reboot or running
    sudo swapon -a
