Connect to the command line through SSH or with a keyboard and screen.
After that run:
sudo raspi-config
You’ll see the Raspberry Pi Software Configuration Tool (raspi-config) menu screen
Select option 7 – Advanced Options
Then select option A1 – Expand Filesystem
If successful, you’ll see the following message:
Root partition has been resized The filesystem will be enlarged upon the next reboot
Use the arrow keys to make selections in the Config Tool menu
Select <Ok>
Select <Back>
Select <Finish>
Then reboot the PI
sudo reboot
Once back up and running, open the Terminal and enter the following:
df -h
You should now see the increased Size next to /dev/root in listed output
Example Output /dev/root (Size) 15G (Avail) 5.9G (Use) 43% (Mounted on) /
Congrats, you have now successfully expanded your SD card.
