etc_fstab

Use the etc_fstab InSpec audit resource to test information about all partitions and storage devices on a Linux system.


Syntax

An etc_fstab rule specifies a device name, its mount point, its mount type, the options its mounted with, its dump options, and the order the files system should be checked.

Use the where clause to match a property to one or more rules in the fstab file:

describe etc_fstab.where { device_name == 'value' } do
  its('mount_point') { should cmp 'hostname' }
  its('file_system_type') { should cmp 'list' }
  its('mount_options') { should cmp 'list' }
  its('dump_options') { should cmp 'list' }
  its('file_system_options') { should cmp 'list' }
end

Use the optional constructor parameter to give an alternative path to fstab file:

describe etc_fstab(hosts_path).where { device_name == 'value' } do
  its('mount_point') { should cmp 'hostname' }
  its('file_system_type') { should cmp 'list' }
  its('mount_options') { should cmp 'list' }
  its('dump_options') { should cmp 'list' }
  its('file_system_options') { should cmp 'list ' }
end


Properties

  • device_name is the name associated with the device.
  • mount_point is the directory at which the filesystem is configured to be mounted.
  • file_system_type is the type of file system of the device or partition.
  • mount_options is the options for the device or partition.
  • dump_options is a number used by dump to decide if a file system should be backed up.
  • file_system_options is a number that specifies the order the file system should be checked.


Property Examples

device_name

device_name returns a string array of device names mounted on the system.

describe etc_fstab.where { mount_point == '/mnt/sr0' } do
  its('device_name') { should cmp '/dev/sr0' }
end

mount_point

mount_point returns a string array of directorys at which filesystems are configured to be mounted.

describe etc_fstab.where { device_name == '/dev/sr0' } do
  its('mount_point') { should cmp '/mnt/sr0' }
end

file_system_type

file_system_type returns a String array of each partitions file system type.

describe etc_fstab.where { device_name == '/dev/sr0' } do
  its('file_system_type') { should cmp 'iso9660' }
end

mount_options

mount_options returns a two dimensional array of each partitions mount options.

describe etc_fstab.where { mount_point == '/' } do
  its('mount_options') { should eq [['defaults', 'x-systemd.device-timeout=0']] }
end

dump_options

dump_options returns a integer array of each partitions dump option.

describe etc_fstab.where { device_name == '/dev/sr0' } do
  its('dump_options') { should cmp 0 }
end

filesystemoptions

file_system_options returns a integer array of each partitions file system option.

describe etc_fstab.where { device_name == '/dev/sr0' } do
  its('file_system_options') { should cmp 0 }
end

Check all partitions that have type of ‘nfs’

nfs_systems = etc_fstab.nfs_file_systems.entries
nfs_systems.each do |partition|
  describe partition do
    its('mount_options') { should include 'nosuid' }
  end
end

Check the partition mounted at /home contains ‘nosuid’ in its mount_options

describe etc_fstab do
  its('home_mount_options') { should include 'nosuid' }
end

Check if a partition is mounted at a point

describe etc_fstab.where { mount_point == '/home' } do
  it { should be_configured }
end
