18 This is a fake resource that details the options that can be configured
19 for the CRM Daemon.
20
22 dc-version = string [none]
23 Version of Pacemaker on the cluster´s DC.
24 Includes the hash which identifies the exact changeset it was built
26 from. Used for diagnostic purposes.
27 cluster-infrastructure = string [heartbeat]
29 The messaging stack on which Pacemaker is currently running.
30 Used for informational and diagnostic purposes.
32 dc-deadtime = time [20s]
34 How long to wait for a response from other nodes during startup.
35 The "correct" value will depend on the speed/load of your network
37 and the type of switches used.
38 cluster-recheck-interval = time [15min]
40 Polling interval for time based changes to options, resource
41 parameters and constraints.
42 The Cluster is primarily event driven, however the configuration
44 can have elements that change based on time. To ensure these
45 changes take effect, we can optionally poll the cluster´s status
46 for changes. Allowed values: Zero disables polling. Positive values
47 are an interval in seconds (unless other SI units are specified.
48 eg. 5min)
49 load-threshold = percentage [80%]
51 The maximum amount of system resources that should be used by nodes
52 in the cluster
53 The cluster will slow down its recovery process when the amount of
55 system resources used (currently CPU) approaches this limit
56 node-action-limit = integer [0]
58 The maximum number of jobs that can be scheduled per node. Defaults
59 to 2x cores
60 election-timeout = time [2min]
62 *** Advanced Use Only ***.
63 If need to adjust this value, it probably indicates the presence of
65 a bug.
66 shutdown-escalation = time [20min]
68 *** Advanced Use Only ***.
69 If need to adjust this value, it probably indicates the presence of
71 a bug.
72 crmd-integration-timeout = time [3min]
74 *** Advanced Use Only ***.
75 If need to adjust this value, it probably indicates the presence of
77 a bug.
78 crmd-finalization-timeout = time [30min]
80 *** Advanced Use Only ***.
81 If you need to adjust this value, it probably indicates the
83 presence of a bug.
84 crmd-transition-delay = time [0s]
86 *** Advanced Use Only *** Enabling this option will slow down
87 cluster recovery under all conditions
88 Delay cluster recovery for the configured interval to allow for
90 additional/related events to occur. Useful if your configuration is
91 sensitive to the order in which ping updates arrive.
92 stonith-watchdog-timeout = time [(null)]
94 How long to wait before we can assume nodes are safely down
95 stonith-max-attempts = integer [10]
97 How many times stonith can fail before it will no longer be
98 attempted on a target
99 expected-quorum-votes = integer [2]
101 The number of nodes expected to be in the cluster
102 Used to calculate quorum in openais based clusters.
