4. Cluster Resources

4.1. What is a Cluster Resource?

A resource is a service managed by Pacemaker. The simplest type of resource, a primitive, is described in this chapter. More complex forms, such as groups and clones, are described in later chapters.

Every primitive has a resource agent that provides Pacemaker a standardized interface for managing the service. This allows Pacemaker to be agnostic about the services it manages. Pacemaker doesn’t need to understand how the service works because it relies on the resource agent to do the right thing when asked.

Every resource has a class specifying the standard that its resource agent follows, and a type identifying the specific service being managed.

4.2. Resource Classes

Pacemaker supports several classes, or standards, of resource agents:

• OCF
• LSB
• Systemd
• Upstart (deprecated)
• Service
• Fencing
• Nagios

4.2.1. Open Cluster Framework

The Open Cluster Framework (OCF) Resource Agent API is a ClusterLabs standard for managing services. It is the most preferred since it is specifically designed for use in a Pacemaker cluster.

OCF agents are scripts that support a variety of actions including start, stop, and monitor. They may accept parameters, making them more flexible than other classes. The number and purpose of parameters is left to the agent, which advertises them via the meta-data action.

Unlike other classes, OCF agents have a provider as well as a class and type.

For more information, see the “Resource Agents” chapter of Pacemaker Administration and the OCF standard.

4.2.2. Systemd

Most Linux distributions use Systemd for system initialization and service management. Unit files specify how to manage services and are usually provided by the distribution.

Pacemaker can manage systemd services. Simply create a resource with systemd as the resource class and the unit file name as the resource type. Do not run systemctl enable on the unit.

Important

Make sure that any systemd services to be controlled by the cluster are not enabled to start at boot.

4.2.3. Linux Standard Base

LSB resource agents, also known as SysV-style, are scripts that provide start, stop, and status actions for a service.

They are provided by some operating system distributions. If a full path is not given, they are assumed to be located in a directory specified when your Pacemaker software was built (usually /etc/init.d).

In order to be used with Pacemaker, they must conform to the LSB specification as it relates to init scripts.

Warning

Some LSB scripts do not fully comply with the standard. For details on how to check whether your script is LSB-compatible, see the “Resource Agents” chapter of Pacemaker Administration. Common problems include:

• Not implementing the status action
• Not observing the correct exit status codes
• Starting a started resource returns an error
• Stopping a stopped resource returns an error

Important

Make sure the host is not configured to start any LSB services at boot that will be controlled by the cluster.

4.2.4. Upstart

Some Linux distributions previously used Upstart for system initialization and service management. Pacemaker is able to manage services using Upstart if the local system supports them and support was enabled when your Pacemaker software was built.

The jobs that specify how services are managed are usually provided by the operating system distribution.

Important

Make sure the host is not configured to start any Upstart services at boot that will be controlled by the cluster.

Warning

Upstart support is deprecated in Pacemaker. Upstart is no longer actively maintained, and test platforms for it are no longer readily usable. Support will be dropped entirely at the next major release of Pacemaker.

4.2.5. System Services

Since there are various types of system services (systemd, upstart, and lsb), Pacemaker supports a special service alias which intelligently figures out which one applies to a given cluster node.

This is particularly useful when the cluster contains a mix of systemd, upstart, and lsb.

In order, Pacemaker will try to find the named service as:

• an LSB init script
• a Systemd unit file
• an Upstart job

4.2.6. STONITH

The stonith class is used for managing fencing devices, discussed later in Fencing.

4.2.7. Nagios Plugins

Nagios Plugins [1] are a way to monitor services. Pacemaker can use these as resources, to react to a change in the service’s status.

To use plugins as resources, Pacemaker must have been built with support, and OCF-style meta-data for the plugins must be installed on nodes that can run them. Meta-data for several common plugins is provided by the nagios-agents-metadata project.

The supported parameters for such a resource are same as the long options of the plugin.

Start and monitor actions for plugin resources are implemented as invoking the plugin. A plugin result of “OK” (0) is treated as success, a result of “WARN” (1) is treated as a successful but degraded service, and any other result is considered a failure.

A plugin resource is not going to change its status after recovery by restarting the plugin, so using them alone does not make sense with on-fail set (or left to default) to restart. Another value could make sense, for example, if you want to fence or standby nodes that cannot reach some external service.

A more common use case for plugin resources is to configure them with a container meta-attribute set to the name of another resource that actually makes the service available, such as a virtual machine or container.

With container set, the plugin resource will automatically be colocated with the containing resource and ordered after it, and the containing resource will be considered failed if the plugin resource fails. This allows monitoring of a service inside a virtual machine or container, with recovery of the virtual machine or container if the service fails.

Configuring a virtual machine as a guest node, or a container as a bundle, is the preferred way of monitoring a service inside, but plugin resources can be useful when it is not practical to modify the virtual machine or container image for this purpose.

4.3. Resource Properties

These values tell the cluster which resource agent to use for the resource, where to find that resource agent and what standards it conforms to.

Properties of a Primitive Resource

Field	Description
id	Your name for the resource
class	The standard the resource agent conforms to. Allowed values: lsb, nagios, ocf, service, stonith, systemd, upstart
description	A description of the Resource Agent, intended for local use. E.g. IP address for website
type	The name of the Resource Agent you wish to use. E.g. IPaddr or Filesystem
provider	The OCF spec allows multiple vendors to supply the same resource agent. To use the OCF resource agents supplied by the Heartbeat project, you would specify heartbeat here.

The XML definition of a resource can be queried with the crm_resource tool. For example:

# crm_resource --resource Email --query-xml

might produce:

A system resource definition

<primitive id="Email" class="service" type="exim"/>

Note

One of the main drawbacks to system services (LSB, systemd or Upstart) resources is that they do not allow any parameters!

An OCF resource definition

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
   <instance_attributes id="Public-IP-params">
      <nvpair id="Public-IP-ip" name="ip" value="192.0.2.2"/>
   </instance_attributes>
</primitive>

4.4. Resource Options

Resources have two types of options: meta-attributes and instance attributes. Meta-attributes apply to any type of resource, while instance attributes are specific to each resource agent.

4.4.1. Resource Meta-Attributes

Meta-attributes are used by the cluster to decide how a resource should behave and can be easily set using the --meta option of the crm_resource command.

Meta-attributes of a Primitive Resource

Field	Default	Description
priority	0	If not all resources can be active, the cluster will stop lower priority resources in order to keep higher priority ones active.
critical	true	Use this value as the default for influence in all colocation constraints involving this resource, as well as the implicit colocation constraints created if this resource is in a group. For details, see Colocation Influence. (since 2.1.0)
target-role	Started	What state should the cluster attempt to keep this resource in? Allowed values: Stopped: Force the resource to be stopped Started: Allow the resource to be started (and in the case of promotable clone resources, promoted if appropriate) Unpromoted: Allow the resource to be started, but only in the unpromoted role if the resource is promotable Promoted: Equivalent to Started
is-managed	TRUE	Is the cluster allowed to start and stop the resource? Allowed values: true, false
maintenance	FALSE	Similar to the maintenance-mode cluster option, but for a single resource. If true, the resource will not be started, stopped, or monitored on any node. This differs from is-managed in that monitors will not be run. Allowed values: true, false
resource-stickiness	1 for individual clone instances, 0 for all other resources	A score that will be added to the current node when a resource is already active. This allows running resources to stay where they are, even if they would be placed elsewhere if they were being started from a stopped state.
requires	quorum for resources with a class of stonith, otherwise unfencing if unfencing is active in the cluster, otherwise fencing if stonith-enabled is true, otherwise quorum	Conditions under which the resource can be started. Allowed values: nothing: can always be started quorum: The cluster can only start this resource if a majority of the configured nodes are active fencing: The cluster can only start this resource if a majority of the configured nodes are active and any failed or unknown nodes have been fenced unfencing: The cluster can only start this resource if a majority of the configured nodes are active and any failed or unknown nodes have been fenced and only on nodes that have been unfenced
migration-threshold	INFINITY	How many failures may occur for this resource on a node, before this node is marked ineligible to host this resource. A value of 0 indicates that this feature is disabled (the node will never be marked ineligible); by constrast, the cluster treats INFINITY (the default) as a very large but finite number. This option has an effect only if the failed operation specifies on-fail as restart (the default), and additionally for failed start operations, if the cluster property start-failure-is-fatal is false.
failure-timeout	0	How many seconds to wait before acting as if the failure had not occurred, and potentially allowing the resource back to the node on which it failed. A value of 0 indicates that this feature is disabled.
multiple-active	stop_start	What should the cluster do if it ever finds the resource active on more than one node? Allowed values: block: mark the resource as unmanaged stop_only: stop all active instances and leave them that way stop_start: stop all active instances and start the resource in one location only stop_unexpected: stop all active instances except where the resource should be active (this should be used only when extra instances are not expected to disrupt existing instances, and the resource agent’s monitor of an existing instance is capable of detecting any problems that could be caused; note that any resources ordered after this will still need to be restarted)
allow-migrate	TRUE for ocf:pacemaker:remote resources, FALSE otherwise	Whether the cluster should try to “live migrate” this resource when it needs to be moved (see Migrating Resources)
allow-unhealthy-nodes	FALSE	Whether the resource should be able to run on a node even if the node’s health score would otherwise prevent it (see Tracking Node Health) (since 2.1.3)
container-attribute-target		Specific to bundle resources; see Bundle Node Attributes
remote-node		The name of the Pacemaker Remote guest node this resource is associated with, if any. If specified, this both enables the resource as a guest node and defines the unique name used to identify the guest node. The guest must be configured to run the Pacemaker Remote daemon when it is started. WARNING: This value cannot overlap with any resource or node IDs.
remote-port	3121	If remote-node is specified, the port on the guest used for its Pacemaker Remote connection. The Pacemaker Remote daemon on the guest must be configured to listen on this port.
remote-addr	value of remote-node	If remote-node is specified, the IP address or hostname used to connect to the guest via Pacemaker Remote. The Pacemaker Remote daemon on the guest must be configured to accept connections on this address.
remote-connect-timeout	60s	If remote-node is specified, how long before a pending guest connection will time out.

As an example of setting resource options, if you performed the following commands on an LSB Email resource:

# crm_resource --meta --resource Email --set-parameter priority --parameter-value 100
# crm_resource -m -r Email -p multiple-active -v block

the resulting resource definition might be:

An LSB resource with cluster options

<primitive id="Email" class="lsb" type="exim">
  <meta_attributes id="Email-meta_attributes">
    <nvpair id="Email-meta_attributes-priority" name="priority" value="100"/>
    <nvpair id="Email-meta_attributes-multiple-active" name="multiple-active" value="block"/>
  </meta_attributes>
</primitive>

In addition to the cluster-defined meta-attributes described above, you may also configure arbitrary meta-attributes of your own choosing. Most commonly, this would be done for use in rules. For example, an IT department might define a custom meta-attribute to indicate which company department each resource is intended for. To reduce the chance of name collisions with cluster-defined meta-attributes added in the future, it is recommended to use a unique, organization-specific prefix for such attributes.

4.4.2. Setting Global Defaults for Resource Meta-Attributes

To set a default value for a resource option, add it to the rsc_defaults section with crm_attribute. For example,

# crm_attribute --type rsc_defaults --name is-managed --update false

would prevent the cluster from starting or stopping any of the resources in the configuration (unless of course the individual resources were specifically enabled by having their is-managed set to true).

4.4.3. Resource Instance Attributes

The resource agents of some resource classes (lsb, systemd and upstart not among them) can be given parameters which determine how they behave and which instance of a service they control.

If your resource agent supports parameters, you can add them with the crm_resource command. For example,

# crm_resource --resource Public-IP --set-parameter ip --parameter-value 192.0.2.2

would create an entry in the resource like this:

An example OCF resource with instance attributes

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
   <instance_attributes id="params-public-ip">
      <nvpair id="public-ip-addr" name="ip" value="192.0.2.2"/>
   </instance_attributes>
</primitive>

For an OCF resource, the result would be an environment variable called OCF_RESKEY_ip with a value of 192.0.2.2.

The list of instance attributes supported by an OCF resource agent can be found by calling the resource agent with the meta-data command. The output contains an XML description of all the supported attributes, their purpose and default values.

4.5. Resource Operations

Operations are actions the cluster can perform on a resource by calling the resource agent. Resource agents must support certain common operations such as start, stop, and monitor, and may implement any others.

Operations may be explicitly configured for two purposes: to override defaults for options (such as timeout) that the cluster will use whenever it initiates the operation, and to run an operation on a recurring basis (for example, to monitor the resource for failure).

An OCF resource with a non-default start timeout

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
  <operations>
     <op id="Public-IP-start" name="start" timeout="60s"/>
  </operations>
  <instance_attributes id="params-public-ip">
     <nvpair id="public-ip-addr" name="ip" value="192.0.2.2"/>
  </instance_attributes>
</primitive>

Pacemaker identifies operations by a combination of name and interval, so this combination must be unique for each resource. That is, you should not configure two operations for the same resource with the same name and interval.

4.5.1. Operation Properties

Operation properties may be specified directly in the op element as XML attributes, or in a separate meta_attributes block as nvpair elements. XML attributes take precedence over nvpair elements if both are specified.

Properties of an Operation

Field	Default	Description
id		A unique name for the operation.
name		The action to perform. This can be any action supported by the agent; common values include monitor, start, and stop.
interval	0	How frequently (in seconds) to perform the operation. A value of 0 means “when needed”. A positive value defines a recurring action, which is typically used with monitor.
timeout		How long to wait before declaring the action has failed
on-fail	Varies by action: stop: fence if stonith-enabled is true or block otherwise demote: on-fail of the monitor action with role set to Promoted, if present, enabled, and configured to a value other than demote, or restart otherwise all other actions: restart	The action to take if this action ever fails. Allowed values: ignore: Pretend the resource did not fail. block: Don’t perform any further operations on the resource. stop: Stop the resource and do not start it elsewhere. demote: Demote the resource, without a full restart. This is valid only for promote actions, and for monitor actions with both a nonzero interval and role set to Promoted; for any other action, a configuration error will be logged, and the default behavior will be used. (since 2.0.5) restart: Stop the resource and start it again (possibly on a different node). fence: STONITH the node on which the resource failed. standby: Move all resources away from the node on which the resource failed.
enabled	TRUE	If false, ignore this operation definition. This is typically used to pause a particular recurring monitor operation; for instance, it can complement the respective resource being unmanaged (is-managed=false), as this alone will not block any configured monitoring. Disabling the operation does not suppress all actions of the given type. Allowed values: true, false.
record-pending	TRUE	If true, the intention to perform the operation is recorded so that GUIs and CLI tools can indicate that an operation is in progress. This is best set as an operation default (see Setting Global Defaults for Operations). Allowed values: true, false.
role		Run the operation only on node(s) that the cluster thinks should be in the specified role. This only makes sense for recurring monitor operations. Allowed (case-sensitive) values: Stopped, Started, and in the case of promotable clone resources, Unpromoted and Promoted.

Note

When on-fail is set to demote, recovery from failure by a successful demote causes the cluster to recalculate whether and where a new instance should be promoted. The node with the failure is eligible, so if promotion scores have not changed, it will be promoted again.

There is no direct equivalent of migration-threshold for the promoted role, but the same effect can be achieved with a location constraint using a rule with a node attribute expression for the resource’s fail count.

For example, to immediately ban the promoted role from a node with any failed promote or promoted instance monitor:

<rsc_location id="loc1" rsc="my_primitive">
    <rule id="rule1" score="-INFINITY" role="Promoted" boolean-op="or">
      <expression id="expr1" attribute="fail-count-my_primitive#promote_0"
        operation="gte" value="1"/>
      <expression id="expr2" attribute="fail-count-my_primitive#monitor_10000"
        operation="gte" value="1"/>
    </rule>
</rsc_location>

This example assumes that there is a promotable clone of the my_primitive resource (note that the primitive name, not the clone name, is used in the rule), and that there is a recurring 10-second-interval monitor configured for the promoted role (fail count attributes specify the interval in milliseconds).

4.5.2. Monitoring Resources for Failure

When Pacemaker first starts a resource, it runs one-time monitor operations (referred to as probes) to ensure the resource is running where it’s supposed to be, and not running where it’s not supposed to be. (This behavior can be affected by the resource-discovery location constraint property.)

Other than those initial probes, Pacemaker will not (by default) check that the resource continues to stay healthy [2]. You must configure monitor operations explicitly to perform these checks.

An OCF resource with a recurring health check

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
  <operations>
     <op id="Public-IP-start" name="start" timeout="60s"/>
     <op id="Public-IP-monitor" name="monitor" interval="60s"/>
  </operations>
  <instance_attributes id="params-public-ip">
     <nvpair id="public-ip-addr" name="ip" value="192.0.2.2"/>
  </instance_attributes>
</primitive>

By default, a monitor operation will ensure that the resource is running where it is supposed to. The target-role property can be used for further checking.

For example, if a resource has one monitor operation with interval=10 role=Started and a second monitor operation with interval=11 role=Stopped, the cluster will run the first monitor on any nodes it thinks should be running the resource, and the second monitor on any nodes that it thinks should not be running the resource (for the truly paranoid, who want to know when an administrator manually starts a service by mistake).

Note

Currently, monitors with role=Stopped are not implemented for clone resources.

4.5.3. Monitoring Resources When Administration is Disabled

Recurring monitor operations behave differently under various administrative settings:

• When a resource is unmanaged (by setting is-managed=false): No monitors will be stopped.

  If the unmanaged resource is stopped on a node where the cluster thinks it should be running, the cluster will detect and report that it is not, but it will not consider the monitor failed, and will not try to start the resource until it is managed again.

  Starting the unmanaged resource on a different node is strongly discouraged and will at least cause the cluster to consider the resource failed, and may require the resource’s target-role to be set to Stopped then Started to be recovered.

• When a resource is put into maintenance mode (by setting maintenance=true): The resource will be marked as unmanaged. (This overrides is-managed=true.)

  Additionally, all monitor operations will be stopped, except those specifying role as Stopped (which will be newly initiated if appropriate). As with unmanaged resources in general, starting a resource on a node other than where the cluster expects it to be will cause problems.

• When a node is put into standby: All resources will be moved away from the node, and all monitor operations will be stopped on the node, except those specifying role as Stopped (which will be newly initiated if appropriate).

• When a node is put into maintenance mode: All resources that are active on the node will be marked as in maintenance mode. See above for more details.

• When the cluster is put into maintenance mode: All resources in the cluster will be marked as in maintenance mode. See above for more details.

A resource is in maintenance mode if the cluster, the node where the resource is active, or the resource itself is configured to be in maintenance mode. If a resource is in maintenance mode, then it is also unmanaged. However, if a resource is unmanaged, it is not necessarily in maintenance mode.

4.5.4. Setting Global Defaults for Operations

You can change the global default values for operation properties in a given cluster. These are defined in an op_defaults section of the CIB’s configuration section, and can be set with crm_attribute. For example,

# crm_attribute --type op_defaults --name timeout --update 20s

would default each operation’s timeout to 20 seconds. If an operation’s definition also includes a value for timeout, then that value would be used for that operation instead.

4.5.5. When Implicit Operations Take a Long Time

The cluster will always perform a number of implicit operations: start, stop and a non-recurring monitor operation used at startup to check whether the resource is already active. If one of these is taking too long, then you can create an entry for them and specify a longer timeout.

An OCF resource with custom timeouts for its implicit actions

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
  <operations>
     <op id="public-ip-startup" name="monitor" interval="0" timeout="90s"/>
     <op id="public-ip-start" name="start" interval="0" timeout="180s"/>
     <op id="public-ip-stop" name="stop" interval="0" timeout="15min"/>
  </operations>
  <instance_attributes id="params-public-ip">
     <nvpair id="public-ip-addr" name="ip" value="192.0.2.2"/>
  </instance_attributes>
</primitive>

4.5.6. Multiple Monitor Operations

Provided no two operations (for a single resource) have the same name and interval, you can have as many monitor operations as you like. In this way, you can do a superficial health check every minute and progressively more intense ones at higher intervals.

To tell the resource agent what kind of check to perform, you need to provide each monitor with a different value for a common parameter. The OCF standard creates a special parameter called OCF_CHECK_LEVEL for this purpose and dictates that it is “made available to the resource agent without the normal OCF_RESKEY prefix”.

Whatever name you choose, you can specify it by adding an instance_attributes block to the op tag. It is up to each resource agent to look for the parameter and decide how to use it.

An OCF resource with two recurring health checks, performing different levels of checks specified via OCF_CHECK_LEVEL.

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
   <operations>
      <op id="public-ip-health-60" name="monitor" interval="60">
         <instance_attributes id="params-public-ip-depth-60">
            <nvpair id="public-ip-depth-60" name="OCF_CHECK_LEVEL" value="10"/>
         </instance_attributes>
      </op>
      <op id="public-ip-health-300" name="monitor" interval="300">
         <instance_attributes id="params-public-ip-depth-300">
            <nvpair id="public-ip-depth-300" name="OCF_CHECK_LEVEL" value="20"/>
         </instance_attributes>
     </op>
   </operations>
   <instance_attributes id="params-public-ip">
       <nvpair id="public-ip-level" name="ip" value="192.0.2.2"/>
   </instance_attributes>
</primitive>

4.5.7. Disabling a Monitor Operation

The easiest way to stop a recurring monitor is to just delete it. However, there can be times when you only want to disable it temporarily. In such cases, simply add enabled=false to the operation’s definition.

Example of an OCF resource with a disabled health check

<primitive id="Public-IP" class="ocf" type="IPaddr" provider="heartbeat">
   <operations>
      <op id="public-ip-check" name="monitor" interval="60s" enabled="false"/>
   </operations>
   <instance_attributes id="params-public-ip">
      <nvpair id="public-ip-addr" name="ip" value="192.0.2.2"/>
   </instance_attributes>
</primitive>

This can be achieved from the command line by executing:

# cibadmin --modify --xml-text '<op id="public-ip-check" enabled="false"/>'

Once you’ve done whatever you needed to do, you can then re-enable it with

# cibadmin --modify --xml-text '<op id="public-ip-check" enabled="true"/>'

[1]	The project has two independent forks, hosted at https://www.nagios-plugins.org/ and https://www.monitoring-plugins.org/. Output from both projects’ plugins is similar, so plugins from either project can be used with pacemaker.

[2]	Currently, anyway. Automatic monitoring operations may be added in a future version of Pacemaker.
