Please run the following commands to resize a partition.
IMPORTANT NOTE: Don't forget to change partition address from /dev/sdb2 to your actual partition!
CHANGES ARE DONE IN TWO OR THREE PLACES.
Example below are for /dev/sdb2 partition which is called like "/dev/sdb 2" for growpart
and like "/dev/sdb2" for resize2fs & e2fsck.
Requirements: * growpart; * resize2fs; * e2fsck if disk requires checking.
Install growpart in arch/manjaro: pikaur -S growpart (resize2fs and e2fsck are usually bundled with OS)

sudo growpart /dev/sdb 2
sudo resize2fs /dev/sdb2

Also run as a oneliner is possible:

sudo growpart /dev/sdb 2 && sudo resize2fs /dev/sdb2

If it asks for checking partition errors, use this:

sudo e2fsck -f /dev/sdb2

Or, as a oneliner:

sudo growpart /dev/sdb 2 && sudo e2fsck -f /dev/sdb2 && sudo resize2fs /dev/sdb2

NOTE: The following works for EXT4 parition. If your parition is F2FS, please use:

resize.f2fs /dev/sdb2

After issuing this command you might want also to run sudo gparted and check if your partition is now filled in full.
