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 manages. They should be the minimum advised timeouts, but they shouldn't/cannot 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 nativemigration if available in the cluster manager. For Pacemaker, the allow-migrate="true" meta attribute enables native migration.

The following is an example configuration for a dummypy resource using the crm(8) shell: primitive p_dummypy ocf:heartbeat:dummypy \ meta allow-migrate="true" \ op monitor timeout="20s" interval="10s" depth="0"

Example Pcs

The following is an example configuration for a dummypy resource using pcs(8) pcs resource create p_dummypy ocf:heartbeat:dummypy \ op monitor timeout="20s" interval="10s" OCF_CHECK_LEVEL="0"
