Resource Group Manager

The Resource Group Manager (RGM) is implemented as a daemon, rgmd, that runs on the global-cluster voting node in a cluster. All of the rgmd processes communicate with each other and act as a single cluster-wide facility.

The RGM supports the following functions:

Whenever the RGM activates configuration changes, it coordinates its actions across all member nodes of the cluster. This kind of activity is known as a reconfiguration. To effect a state change on an individual resource, the RGM runs a resource type-specific callback method on that resource.
