Promotable clone resources require two extra actions, demote and promote, which are responsible for changing the state of the resource. Like start and stop, they should return ${OCF_SUCCESS} if they completed successfully or a relevant error code if they did not.

The states can mean whatever you wish, but when the resource is started, it must come up in the mode called slave. From there the cluster will decide which instances to promote to master.

In addition to the clone requirements for monitor actions, agents must also accurately report which state they are in. The cluster relies on the agent to report its status (including role) accurately and does not indicate to the agent what role it currently believes it to be in.
