# filesystem

Use the `filesystem` InSpec resource to audit filesystem disk space usage.

<br>

## Syntax

A `filesystem` resource block declares tests for disk space in a partition:

    describe filesystem('/') do
      its('size') { should be >= 32000 }
    end

where

* `filesystem('/')` states that the resource will look at the root (/) partition.
* `size` is measured in megabytes (MB).

<br>

## Resource Property Examples

The following examples show how to use this InSpec audit resource.

### Test if the root partition is greater than 32000 MB

    describe filesystem('/') do
      its('size') { should be >= 32000 }
    end
