Fuel module for Pacemaker

These manfisests are derived from puppetlabs-corosync modules v0.1.0.

Basic usage

Configuring primitives

The resources that Pacemaker will manage can be referred to as a primitive. These are things like virtual IPs or services like drbd, nginx, and apache.

To assign a VIP to a network interface to be used by Nginx

cs_resource { 'nginx_vip':
  primitive_class => 'ocf',
  primitive_type  => 'IPaddr2',
  provided_by     => 'heartbeat',
  parameters      => { 'ip' => '172.16.210.100', 'cidr_netmask' => '24' },
  operations      => { 'monitor' => { 'interval' => '10s' } },
}

Make Pacemaker manage and monitor the state of Nginx using a custom OCF agent

cs_resource { 'nginx_service':
  primitive_class => 'ocf',
  primitive_type  => 'nginx_fixed',
  provided_by     => 'pacemaker',
  operations      => {
    'monitor' => { 'interval' => '10s', 'timeout' => '30s' },
    'start'   => { 'interval' => '0', 'timeout' => '30s', 'on-fail' => 'restart' }
  },
  require         => Cs_primitive['nginx_vip'],
}

Make Pacemaker manage and monitor the state of Apache using a LSB agent

cs_resource { 'nginx_service':
  primitive_class => 'lsb',
  primitive_type  => 'apache2',
  provided_by     => 'heartbeat',
  operations      => {
    'monitor' => { 'interval' => '10s', 'timeout' => '30s' },
    'start'   => { 'interval' => '0', 'timeout' => '30s', 'on-fail' => 'restart' }
  },
  require         => Cs_primitive['apache2_vip'],
}

*You can also specify multi-state resource such as clone or master

cs_resource {'nginx_service':
primitive_class => 'lsb',
  provided_by     => 'heartbeat',
  operations      => {
    'monitor' => { 'interval' => '10s', 'timeout' => '30s' },
    'start'   => { 'interval' => '0', 'timeout' => '30s', 'on-fail' => 'restart' }
  },
  require         => Cs_primitive['apache2_vip'],
  multistate_hash => {'type'=>'clone','name'=>'nginx_clone'
  ms_metadata => {'interleave'=>'true'}
  }
}

Dependencies

Tested and built on Ubuntu 12.04 with 1.4.2 of Corosync is validated to function.
