Storage and File Systems

I am over the File System Quota

There are two resources with limits enforced by quota:

• disk space
• number of inodes (files).

It is important to identify the main sources that consume these resources.

• Size: List all directories (and files) in your home directory or workspace sorted by size

du -hs .[!.]* * | sort -h | tail

Descend in a directory with a large reported size and repeat until you find large files that are worth taking care of.

.[!.]* makes sure the "hidden" dot files are also checked.

• Inodes:

du -s --inodes .[!.]* * | sort -n

This will only count inodes in subdirectories. Also make sure your top-level (e.g. $HOME) directory aren't full with hundred thousands of files:

ls -1a | wc -l
