Add a swap partition.
Adding an extra 500M swap partition to your system, this swap partition should mount automatically when the system starts up. Don't remove and modify the existing swap partitions on your system.
To add a new 500M swap partition to your system and ensure it mounts automatically at startup, follow these steps. First, create the swap partition. Use the parted or fdisk utility to create a 500M swap partition. For instance, you can use 'sudo parted /dev/sdb' and execute a sequence of commands to create a new partition of type linux-swap. Next, initialize the swap area with the command 'sudo mkswap /dev/sdbX', where /dev/sdbX is the newly created partition. Enable the swap partition immediately using 'sudo swapon /dev/sdbX'. To ensure this partition mounts at startup, add an entry to /etc/fstab by editing the file and adding '/dev/sdbX swap swap defaults 0 0' at the end of the file. Save and exit the editor. Verify the changes have taken effect by running the command 'sudo swapon --show', which will list all active swap spaces.
