# Running Out Of inode Space
Unix systems have two types of storage limitations. The first, and more
common, is a limitation on physical storage used for storing the contents of
files. The second is a limitation on `inode` space which represents file
location and other data.
Though it is uncommon, it is possible to run out of `inode` space before
running out of disk space (run `df` and `df -i` to see the levels of each).
When this happens, the system will complain that there is `No space left on
device`. Both `inode` space and disk space is needed to create a new file.
How can this happen? If lots of directories with lots of empty, small, or
duplicate files are being created, then the `inode` space can be used up
disproportionately to the amount of respective disk space. You'll need to
clean up some of those files before you can continue.
