Welcome to fdisk (util-linux 2.37.2).
Changes will remain in memory only, until you decide to write them. Be careful before using the write command. GPT PMBR size mismatch (83886079 != 167772159) will be corrected by write. 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 (4-128, default 4):
First sector (83884032-167772126, default 83884032):
Last sector, +/-sectors or +/-size{K,M,G,T,P} (83884032-167772126, default 167772126): Created a new partition 4 of type 'Linux filesystem' and of size 40 GiB.
Command (m for help): w
The partition table has been altered. Syncing disks.
