Overview

Manages the smartmontools package including the smartd daemon

Description

Installs the smartmontools package and enables the smartd service.

If your hardware supports it, smartd can automatically probe for the drives, but if they are hidden behind a RAID controller, it will need additional help. The module includes a facter plugin to identify drives hiding behind an LSI MegaRAID/Dell PERC/Supermicro controller on Linux systems if you have the LSI proprietary MegaCli tool installed; we don't have any FreeBSD machines with this controller so haven't written the necessary code to use FreeBSD's standard mfiutil(8) utility instead.

Currently, drives behind an LSI MegaRAID controller will be automatically probed and added to the smartd configuration file, if the MegaCli utility is installed. There is no way to turn this behavior off. This is arguably a bug.

It is planned that in a future release the megaraid specific facts will be migrated into the puppet-megaraid module.

Forked

This is a fork of csail/smartd that was initially made primarily to fix support of probing SATA drives behind a LSI Megaraid controllers. The author has been aware of the fork and it's hoped that the two modules can be merged. Since the initial fork, a number of small API changes have been made to improve usage.

Usage

Version 2.x.x incompatible API change

The v2 API merges the v1 API's devices and device_options parameters into a single parameter named devices, but with incompatible semantics to the v1 API.

devices now accepts an Array of Hash. This is to allow multiple smartd.conf entries for the same blockdev as is typically required for probing through to individual disks behind a block device presented by a RAID controller.

Old v1 API

Note that devices used to accept a flat Array.

    class{ 'smartd':
      devices        => [ '/dev/sg1', '/dev/sg2' ],
      device_options => { '/dev/sg1' => '-o on -S on -a', '/dev/sg2' => '-o on -S on -a' },
    }

New v2 API

devices now accepts an Array of Hash.

    class{ 'smartd':
      devices => [
        { device => '/dev/sg1', options => '-o on -S on -a' },
        { device => '/dev/sg2', options => '-o on -S on -a' },
      ],
    }

Simple Usage

    include smartd

    class{ 'smartd': }

Parameters

All parameters are optional.

ensure

String defaults to: present

Standard Puppet ensure semantics (and supports purged state if your package provider does). Valid values are: present,latest,absent,purged

package_name

String defaults to: smartmontools

Name of the smartmontools package.

service_name

String defaults to: smartd

Name of the smartmontools monitoring daemon.

service_ensure

String defaults to: running

State of the smartmontools monitoring daemon. Valid values are: running,stopped

config_file

String defaults to: (OS-specific)

Path to the configuration file for the monitoring daemon.

devicescan

Bool defaults to: true

Sets the DEVICESCAN directive in the smart daemon config file. Tells the smart daemon to automatically detect all of the SMART-capable drives in the system.

devicescan_options

String defaults to: undef

Passes options to the DEVICESCAN directive. devicescan must equal true for this to have any effect.

devices

Array of Hash defaults to: []

Explicit list of raw block devices to check. Eg.

    [{ device => '/dev/sda', options => '-I 194' }]

mail_to

String defaults to: root

Smart daemon notification email address.

warning_schedule

String defaults to: daily

Smart daemon problem mail notification frequency. Valid values are: daily,once,diminishing

enable_default

Bool defaults to: true if $::smartmontools_version >= 5.43, otherwise false

Enables/disables the DEFAULT directive in the smartd.conf file. This directive was added in the 5.43 release of smartmontools and is unsupported in previous versions.

If enable_default is set to false the the values from the mail_to and warning_schedule parameters are set on the DEVICESCAN directive (if enabled) instead of the [absent] DEFAULT directive.

Example smartd.conf content based on this setting:

enable_default => true

# Managed by Puppet -- do not edit!
DEFAULT -m root -M daily
DEVICESCAN

enable_default => false

# Managed by Puppet -- do not edit!
DEVICESCAN -m root -M daily

Here is an example of the error message generated by the DEFFAULT directive appearing in the configuration file of 5.42.

smartd 5.42 2011-10-20 r3458 [i686-linux-2.6.18-371.6.1.el5PAE] (local build)
Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net
Opened configuration file /etc/smartd.conf
Drive: DEFAULT, implied '-a' Directive on line 2 of file /etc/smartd.conf
Drive: DEVICESCAN, implied '-a' Directive on line 3 of file /etc/smartd.conf
Configuration file /etc/smartd.conf was parsed, found DEVICESCAN, scanning devices
Device: DEFAULT, unable to autodetect device type

This option could not be named default to be consistent with the naming convention of the other parameters in this module due to this bug PUP-2244 that affects puppet 2.7.x.

Note that RHEL5 ships with 5.42 while RHEL6 ships with 5.43.

default_options

String defaults to: undef

Additional arguments to be set on the DEFAULT directive.

If default is set to false, this parameter's value will be set on the DEVICESCAN directive (if enabled) instead of the [absent] DEFAULT directive.

Pedantic Example

    class{ 'smartd':
      ensure             => 'present',
      package_name       => 'smartmontools',
      service_name       => 'smartd',
      service_ensure     => 'running',
      config_file        => '/etc/smartd.conf',
      devicescan         => true,
      devicescan_options => '-H -m admin@example.com',
      devices            => [
        { device => '/dev/sg1', options => '-o on -S on -a' },
        { device => '/dev/sg2', options => '-o on -S on -a' },
      ],
      mail_to            => 'root',
      warning_schedule   => 'diminishing',
      default            => 'false',
      default_options    => '-H',
    }
