NAME
ocf_heartbeat_Dummy - Example stateless resource agent
SYNOPSIS
Dummy [start | stop | monitor | reload | 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.
