# zfs_dataset

Use the `zfs_dataset` InSpec audit resource to test the ZFS datasets on FreeBSD systems.

## Syntax

A `zfs_dataset` resource block declares the ZFS dataset properties that should be tested:

    describe zfs_dataset('dataset') do
      it { should MATCHER 'value' }
    end

where

* `('dataset')` is the name of the ZFS dataset (eg: `'tank/tmp'`)
* `MATCHER` is a valid matcher for this resource
* `'value'` is the value to be tested


## Matchers

This InSpec audit resource has the matchers listed below, in addition to dynamically exposing all ZFS dataset properties available (see: `man zfs` for the list of supported properties.)

### be

<%= partial "/shared/matcher_be" %>

### be_mounted

The `be_mounted` matcher tests if the dataset is accessible from the file system:

    it { should be_mounted }

### cmp

<%= partial "/shared/matcher_cmp" %>

### eq

<%= partial "/shared/matcher_eq" %>

### match

<%= partial "/shared/matcher_match" %>

## Examples

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

### Test a dataset of 'tank/tmp'

    describe zfs_dataset('tank/tmp') do
      it { should be_mounted }
      its('atime') { should eq  'on' }
      its('compression') { should eq  'lz4' }
      its('exec') { should eq  'off' }
      its('readonly') { should eq  'off' }
      its('setuid') { should eq  'off' }
    end
