There could be multiple scenarios where you would need to resize the primary partition and
extend non lvm root partition space.

Prerequisites:

• sudo/root access
• Information about disk capacity and existing partition(s)

• Create a data backup (just to be safe).

Let's start with listing our available partitions:

fdisk commands:

• p to print the partition table
• d to delete the partition
• n to create a partition
• w to save changes and exit

Now we will resize a swap partition. Run the following command and use an option p to double check a partition:

Enter d to delete a /dev/vda2 partition;

pick a partition number (from a partition table), in our case, it will be 2;

Enter n to create a new partition and pick a partition type p;

Select a partition number (2-4)

Pick a first sector (we will use a default option);

Pick a partition size - 500M;

Enter N to keep a swap signature;

Use a p command to double check the outcome:

And finally, enter a w command to write the changes to the partition table:
