Resources/Providers

pacemaker_primitive

Configure and delete primitive resource.

This resource manages pacemaker-resource primitives, supporting the following actions: * :create * :delete

Examples

pacemaker_primitive 'drbd' do
  agent "ocf:linbit:drbd"
  params 'drbd_resource' => 'r0'
  op 'monitor' => { 'interval' => '5s', 'role' => 'Master' }
  action :create
end
pacemaker_primitive 'galera' do
  agent "ocf:heartbeat:galera"
  params 'wsrep_cluster_address' => 'node1,node2,node3'
  op 'monitor' => { 'interval' => '5s', 'role' => 'Master'
  ms true
  meta 'master_max' => '1'
  action :create
end

pacemaker_property

Set and unset pacemaker properties.

This resource manages pacemaker properties, supporting the following actions: * :set * :unset

You will want to declare this resource after having created the cluster with the pacemaker::cluster_create recipe.

Examples

pacemaker_property 'default-resource-stickiness' do
  value 4999
end

pacemaker_property 'cluster-recheck-interval' do
  action :unset
end

pacemaker_stonith

Configure and delete stonith resource.

This resource manages pacemaker-resource stonith, supporting the following actions: * :create * :delete

Examples

pacemaker_stonith 'stonith-ucs' do
  agent  'ucs'
  params 'location' => 'b0s0'
  op     'monitor' => { 'interval' => '5s' }
  action :create
end
pacemaker_stonith 'stonith-scsi-sda' do
  agent  'fence_scsi'
  params 'devices' => '/dev/sda'
  meta   'provides' => 'unfencing'
  action :create
end

pacemaker_group

Configure and delete resource groups.

This resource manages pacemaker-resource group, supporting the following actions: * :create * :delete

Examples

pacemaker_clone 'mygroup' do
  resources ['lbservice', 'vip']
  meta {}
  action :create
end

pacemaker_orderset

This resource manages the order pacemaker-contraint using the order set syntax, supporting the following actions: * :create * :delete

Examples

pacemaker_orderset 'start_neutron_layer3' do
  set        ['neutron-netns-clone',
              'neutron-server-clone',
              'neutron-l3-agent-clone',
              'neutron-metadata-agent-clone',
              'neutron-dhcp-agent-clone']
  options 'action' => 'start', 'sequential' => 'true'
  setoptions 'kind' => 'Mandatory'
end

Recipes

pacemaker::default

Include pacemaker::default in your node's run_list:

{
  "name":"my_node",
  "run_list": [
    "recipe[pacemaker::default]"
  ]
}

pacemaker::node_prepare

Installs required components to the node. Does not create or manage a cluster. This recipe assume you already in your run_list a cookbook/recipe to setup repos necessary for packages. You can always choose to just include yum::default in your run_list for default public repositories.

{
  "name":"my_node",
  "run_list": [
    "recipe[pacemaker::node_prepare]"
  ]
}

pacemaker::cluster_create

Creates a pacemaker cluster consisting of node['pacemaker']['corosync']['nodes'].

recipe[pacemaker::node_prepare] must have been ran on all nodes first.

This should be run only from 1 cluster node.

{
  "name":"my_node",
  "run_list": [
    "recipe[pacemaker::cluster_create]"
  ]
}

Testing

Testing utilizes ChefDK >= 0.10.0 with its native gems.

If you run into issues running tests please be sure you do not have extra gems installed in your ChefDK environment as they could cause conflicts.

To be sure you do not have any extra gems installed you can run rm -rf ~/.chefdk/gem to remove any extra gems.
