OK, so this is a fairly standard problem on older versions of Raspbian.
You need to tell the system to expand the root filesystem to use the available space on the SD card. To do this, follow these instructions:
(Optional, but recommended: Go out and re-image with the latest version of the Raspbian OS. As of this writing, that would be Stretch. Jessie is outdated at this time. With Stretch you shouldn't see this problem as it will auto-expand for you.)
For older versions:
- Boot into the Pi and login as the
pi user (password=
- At the command prompt, type
- Select the first option
- The app will go out and apply the necessary changes, then reply with the message
Root partition has been resized. The filesystem will be enlarged upon the next reboot
OK, then select
- When prompted to reboot, select
Your Pi will reboot. When you login next time, try the
df -h command again. The root filesystem should expand now to use up the rest of the SD card space.
