# 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 are 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.
