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.

73 The following is an example configuration for a Dummy resource using
74 the crm(8) shell:
75
76 primitive p_Dummy ocf:heartbeat:Dummy \
77 meta allow-migrate="true" \
78 op monitor timeout="20s" interval="10s" depth="0"
79
81 The following is an example configuration for a Dummy resource using
82 pcs(8)
83
84 pcs resource create p_Dummy ocf:heartbeat:Dummy \
85 op monitor timeout="20s" interval="10s" OCF_CHECK_LEVEL="0"
