Welcome to fdisk (util-linux 2.37.4).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
This disk is currently in use - repartitioning is probably a bad idea.
It's recommended to umount all file systems, and swapoff all swap
partitions on this disk.
Command (m for help): n
Partition number (3-128, default 3):
First sector (1476608-10485726, default 1476608):
Last sector, +/-sectors or +/-size{K,M,G,T,P} (1476608-10485726, default 10485726): +512M
Created a new partition 3 of type 'Linux filesystem' and of size 512 MiB.
Command (m for help): w
The partition table has been altered.
