OCF_HEARTBEAT_DUMMY(7) OCF resource agents OCF_HEARTBEAT_DUMMY(7)NAMEocf_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 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 native migration if available
in the cluster manager. For Pacemaker, the allow-migrate="true" meta
attribute enables native migration.
