Low SD card space

Fri May 31, 2019 9:51 am

On my Raspebbry 2 with SD 16GB is only about 3GB left. I don't install any apps. The basket is empty. Which folder should I look at? Thank you.

Did you expand the filesystem?

The du command (disk usage) is useful (see "man du")

Code: Select all

du -h . | sort -rn | more
prints a list of the sub directories in reverse order of size

When you empty the trash can, the files can be stored in a folder in a different directory instead of being deleted completely, which is still using space on the memory card, you can find the folder in the /home/pi/.local/share/Trash/expunged directory, if you can't delete the folders or the content with the trash can, you need to delete the files using the rm command:

Code: Select all

cd /home/pi/.local/share/Trash/expunged

Code: Select all

sudo rm -R "folder name"

Code: Select all

sudo du -h -d1 / 
Will show the usage of each top level directory.

My system includes

Code: Select all

4.8G	/usr
2.2G	/home
1.2G	/opt
You can then drill down into the larger directories to explore further e.g.

Code: Select all

sudo du -h -d1 /opt 
shows Wolfram is using most of the space
