pcmkr database
Overview
This resource allows you to manage an Pacemaker cluster. Here is an example on how to use this:
pcmkr_database { 'db2inst1/MYDB':
ensure => 'present',
}
All of these properties are read-only. If you need to add nodes, or change interfaces, the cluster must be recreated. At this point in time Puppet does not take care of this.

disable_corrective_change
Disable the modification of a resource when Puppet decides it is a corrective change.
(requires easy_type V2.11.0 or higher)
When using a Puppet Server, Puppet knows about adaptive and corrective changes. A corrective change is when Puppet notices that the resource has changed, but the catalog has not changed. This can occur for example, when a user, by accident or willingly, changed something on the system that Puppet is managing. The normal Puppet process then repairs this and puts the resource back in the state as defined in the catalog. This process is precisely what you want most of the time, but not always. This can sometimes also occur when a hardware or network error occurs. Then Puppet cannot correctly determine the current state of the system and thinks the resource is changed, while in fact, it is not. Letting Puppet recreate remove or change the resource in these cases, is NOT wat you want.
Using the disable_corrective_change
parameter, you can disable corrective changes on the current resource.
Here is an example of this:
crucial_resource {'be_carefull':
...
disable_corrective_change => true,
...
}
When a corrective ensure does happen on the resource Puppet will not modify the resource and signal an error:
Error: Corrective change present requested by catalog, but disabled by parameter disable_corrective_change
Error: /Stage[main]/Main/Crucial_resource[be_carefull]/parameter: change from '10' to '20' failed: Corrective change present requested by catalog, but disabled by parameter disable_corrective_change. (corrective)

Using the disable_corrective_ensure

Here is an example of this:
crucial_resource {'be_carefull':
ensure => 'present',
...
disable_corrective_ensure => true,
...
}
When a corrective ensure does happen on the resource Puppet will not create or remove the resource and signal an error:
Error: Corrective ensure present requested by catalog, but disabled by parameter disable_corrective_ensure.
Error: /Stage[main]/Main/Crucial_resource[be_carefull]/ensure: change from 'absent' to 'present' failed: Corrective ensure present requested by catalog, but disabled by parameter disable_corrective_ensure. (corrective)
