OCF_HEARTBEAT_DUMMY(7) OCF resource agents OCF_HEARTBEAT_DUMMY(7) NAME ocf_heartbeat_Dummy - Example stateless resource agent SYNOPSIS Dummy [start | stop | monitor | migrate_to | migrate_from | meta-data | validate-all] DESCRIPTION This is a Dummy Resource Agent. It does absolutely nothing except keep track of whether its running or not. Its purpose in life is for testing and to serve as a template for RA writers. NB: Please pay attention to the timeouts specified in the actions section below. They should be meaningful for the kind of resource the agent man- ages. They should be the minimum advised timeouts, but they shouldn't/can- not cover _all_ possible resource instances. So, try to be neither overly generous nor too stingy, but moderate. The minimum timeouts should never be below 10 seconds. This resource agent may be configured for native migration if available in the cluster manager. For Pacemaker, the allow-migrate="true" meta attribute enables native migration. SUPPORTED PARAMETERS state Location to store the resource state in. (unique, optional, string, default "/var/run/resource-agents/Dummy-RE- SOURCE_ID.state") fake Fake attribute that can be changed to cause a reload (optional, string, default "dummy") SUPPORTED ACTIONS This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 20s. stop Stops the resource. Suggested minimum timeout: 20s. monitor Performs a detailed status check. Suggested minimum timeout: 20s. Sug- gested interval: 10s. reload Suggested minimum timeout: 20s. migrate_to Executes steps necessary for migrating the resource to the node. Sug- gested minimum timeout: 20s. migrate_from Executes steps necessary for migrating the resource away from the node. Suggested minimum timeout: 20s. meta-data Retrieves resource agent metadata (internal use only). Suggested mini- mum timeout: 5s. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 20s.
