26 Cluster options used by Pacemaker's scheduler
27
29 no-quorum-policy = select [stop]
30 What to do when the cluster does not have quorum
31 What to do when the cluster does not have quorum Allowed values:
33 stop, freeze, ignore, demote, suicide
34 symmetric-cluster = boolean [true]
36 Whether resources can run on any node by default
37 maintenance-mode = boolean [false]
39 Whether the cluster should refrain from monitoring, starting, and
40 stopping resources
41 start-failure-is-fatal = boolean [true]
43 Whether a start failure should prevent a resource from being
44 recovered on the same node
45 When true, the cluster will immediately ban a resource from a node
47 if it fails to start there. When false, the cluster will instead
48 check the resource's fail count against its migration-threshold.
49 enable-startup-probes = boolean [true]
51 Whether the cluster should check for active resources during
52 start-up
53 shutdown-lock = boolean [false]
55 Whether to lock resources to a cleanly shut down node
56 When true, resources active on a node when it is cleanly shut down
58 are kept "locked" to that node (not allowed to run elsewhere) until
59 they start again on that node after it rejoins (or for at most
60 shutdown-lock-limit, if set). Stonith resources and Pacemaker
61 Remote connections are never locked. Clone and bundle instances and
62 the promoted role of promotable clones are currently never locked,
63 though support could be added in a future release.
64 shutdown-lock-limit = time [0]
66 Do not lock resources to a cleanly shut down node longer than this
67 If shutdown-lock is true and this is set to a nonzero time
69 duration, shutdown locks will expire after this much time has
70 passed since the shutdown was initiated, even if the node has not
71 rejoined.
72 stonith-enabled = boolean [true]
74 *** Advanced Use Only *** Whether nodes may be fenced as part of
75 recovery
76 If false, unresponsive nodes are immediately assumed to be
78 harmless, and resources that were active on them may be recovered
79 elsewhere. This can result in a "split-brain" situation,
80 potentially leading to data loss and/or service unavailability.
81 stonith-action = select [reboot]
83 Action to send to fence device when a node needs to be fenced
84 ("poweroff" is a deprecated alias for "off")
85 Action to send to fence device when a node needs to be fenced
87 ("poweroff" is a deprecated alias for "off") Allowed values:
88 reboot, off, poweroff
89 stonith-timeout = time [60s]
91 *** Advanced Use Only *** Unused by Pacemaker
92 This value is not used by Pacemaker, but is kept for backward
94 compatibility, and certain legacy fence agents might use it.
95 have-watchdog = boolean [false]
97 Whether watchdog integration is enabled
98 This is set automatically by the cluster according to whether SBD
100 is detected to be in use. User-configured values are ignored. The
101 value `true` is meaningful if diskless SBD is used and
102 `stonith-watchdog-timeout` is nonzero. In that case, if fencing is
103 required, watchdog-based self-fencing will be performed via SBD
104 without requiring a fencing resource explicitly configured.
105 concurrent-fencing = boolean [false]
107 Allow performing fencing operations in parallel
108 startup-fencing = boolean [true]
110 *** Advanced Use Only *** Whether to fence unseen nodes at start-up
111 Setting this to false may lead to a "split-brain"
113 situation,potentially leading to data loss and/or service
114 unavailability.
115 priority-fencing-delay = time [0]
117 Apply fencing delay targeting the lost nodes with the highest total
118 resource priority
119 Apply specified delay for the fencings that are targeting the lost
121 nodes with the highest total resource priority in case we don't
122 have the majority of the nodes in our cluster partition, so that
123 the more significant nodes potentially win any fencing match, which
124 is especially meaningful under split-brain of 2-node cluster. A
125 promoted resource instance takes the base priority + 1 on
126 calculation if the base priority is not 0. Any static/random delays
127 that are introduced by `pcmk_delay_base/max` configured for the
128 corresponding fencing resources will be added to this delay. This
129 delay should be significantly greater than, safely twice, the
130 maximum `pcmk_delay_base/max`. By default, priority fencing delay
131 is disabled.
132 node-pending-timeout = time [0]
134 How long to wait for a node that has joined the cluster to join the
135 controller process group
136 Fence nodes that do not join the controller process group within
138 this much time after joining the cluster, to allow the cluster to
139 continue managing resources. A value of 0 means never fence pending
140 nodes. Setting the value to 2h means fence nodes after 2 hours.
141 cluster-delay = time [60s]
143 Maximum time for node-to-node communication
144 The node elected Designated Controller (DC) will consider an action
146 failed if it does not get a response from the node executing the
147 action within this time (after considering the action's own
148 timeout). The "correct" value will depend on the speed and load of
149 your network and cluster nodes.
150 batch-limit = integer [0]
152 Maximum number of jobs that the cluster may execute in parallel
153 across all nodes
154 The "correct" value will depend on the speed and load of your
156 network and cluster nodes. If set to 0, the cluster will impose a
157 dynamically calculated limit when any node has a high load.
158 migration-limit = integer [-1]
160 The number of live migration actions that the cluster is allowed to
161 execute in parallel on a node (-1 means no limit)
162 stop-all-resources = boolean [false]
164 Whether the cluster should stop all active resources
165 stop-orphan-resources = boolean [true]
167 Whether to stop resources that were removed from the configuration
168 stop-orphan-actions = boolean [true]
170 Whether to cancel recurring actions removed from the configuration
171 remove-after-stop = boolean [false]
173 *** Deprecated *** Whether to remove stopped resources from the
174 executor
175 Values other than default are poorly tested and potentially
177 dangerous. This option will be removed in a future release.
178 pe-error-series-max = integer [-1]
180 The number of scheduler inputs resulting in errors to save
181 Zero to disable, -1 to store unlimited.
183 pe-warn-series-max = integer [5000]
185 The number of scheduler inputs resulting in warnings to save
186 Zero to disable, -1 to store unlimited.
188 pe-input-series-max = integer [4000]
190 The number of scheduler inputs without errors or warnings to save
191 Zero to disable, -1 to store unlimited.
193 node-health-strategy = select [none]
195 How cluster should react to node health attributes
196 Requires external entities to create node attributes (named with
198 the prefix "#health") with values "red", "yellow", or "green".
199 Allowed values: none, migrate-on-red, only-green, progressive,
200 custom
201 node-health-base = integer [0]
203 Base health score assigned to a node
204 Only used when "node-health-strategy" is set to "progressive".
206 node-health-green = integer [0]
208 The score to use for a node health attribute whose value is "green"
209 Only used when "node-health-strategy" is set to "custom" or
211 "progressive".
212 node-health-yellow = integer [0]
214 The score to use for a node health attribute whose value is
215 "yellow"
216 Only used when "node-health-strategy" is set to "custom" or
218 "progressive".
219 node-health-red = integer [-INFINITY]
221 The score to use for a node health attribute whose value is "red"
222 Only used when "node-health-strategy" is set to "custom" or
224 "progressive".
225 placement-strategy = select [default]
227 How the cluster should allocate resources to nodes
228 How the cluster should allocate resources to nodes Allowed values:
230 default, utilization, minimal, balanced
