SYNOPSIS

DESCRIPTION

13       This is a Dummy Resource Agent. It does absolutely nothing except keep
14       track of whether its running or not. Its purpose in life is for testing
15       and to serve as a template for RA writers.
16
17       NB: Please pay attention to the timeouts specified in the actions
18       section below. They should be meaningful for the kind of resource the
19       agent manages. They should be the minimum advised timeouts, but they
20       shouldn't/cannot cover _all_ possible resource instances. So, try to be
21       neither overly generous nor too stingy, but moderate. The minimum
22       timeouts should never be below 10 seconds.
23
24       This resource agent may be configured for native migration if available
25       in the cluster manager. For Pacemaker, the allow-migrate="true" meta
26       attribute enables native migration.
