16 This text
17 -$, --version
19 Version information
20 -Q, --quiet
22 Display only essentialoutput
23 -V, --verbose
25 Increase debug output
26 Operations:
28 -R, --run
29 Determine the cluster's response to the given configuration and
30 status
31 -S, --simulate Simulate the transition's execution and display the
33 resulting cluster status
34 -X, --in-place Simulate the transition's execution and store the result
36 back to the input file
37 -s, --show-scores
39 Show allocation scores
40 -U, --show-utilization Show utilization information
42 -P, --profile=value
44 Run all tests in the named directory to create profiling data
45 Synthetic Cluster Events:
47 -u, --node-up=value
48 Bring a node online
49 -d, --node-down=value
51 Take a node offline
52 -f, --node-fail=value
54 Mark a node as failed
55 -i, --op-inject=value
57 Generate a failure for the cluster to react to in the simulation
58 Value is of the form ${resource}_${task}_${inter‐
60 val_in_ms}@${node}=${rc}. Eg. memcached_moni‐
61 tor_20000@bart.example.com=7 For more information on OCF return
62 codes, refer to: http://www.clusterlabs.org/doc/en-US/Pace‐
63 maker/1.1/html/Pacemaker_Explained/s-ocf-return-codes.html
64 -F, --op-fail=value
66 If the specified task occurs during the simulation, have it fail
67 with return code ${rc}
68 Value is of the form ${resource}_${task}_${inter‐
70 val_in_ms}@${node}=${rc}. Eg. memcached_stop_0@bart.exam‐
71 ple.com=1
72 The transition will normally stop at the failed action.
74 Save the result with --save-output and re-run with --xml-file
75 -t, --set-datetime=value
77 Set date/time
78 -q, --quorum=value
80 Specify a value for quorum
81 -w, --watchdog=value
83 Assume a watchdog device is active
84 -g, --ticket-grant=value
86 Grant a ticket
87 -r, --ticket-revoke=value
89 Revoke a ticket
90 -b, --ticket-standby=value
92 Make a ticket standby
93 -e, --ticket-activate=value
95 Activate a ticket
96 Output Options:
98 -I, --save-input=value
99 Save the input configuration to the named file
100 -O, --save-output=value
102 Save the output configuration to the named file
103 -G, --save-graph=value
105 Save the transition graph (XML format) to the named file
106 -D, --save-dotfile=value
108 Save the transition graph (DOT format) to the named file
109 -a, --all-actions
111 Display all possible actions in the DOT graph - even ones not
112 part of the transition
113 Data Source:
115 -L, --live-check
116 Connect to the CIB mamager and use the current CIB contents as
117 input
118 -x, --xml-file=value
120 Retrieve XML from the named file
121 -p, --xml-pipe
123 Retrieve XML from stdin
124
126 Pretend a recurring monitor action found memcached stopped on node
127 fred.example.com and, during recovery, that the memcached stop action
128 failed
129 # crm_simulate -LS --op-inject memcached:0_moni‐
131 tor_20000@bart.example.com=7 --op-fail mem‐
132 cached:0_stop_0@fred.example.com=1 --save-output /tmp/mem‐
133 cached-test.xml
134 Now see what the reaction to the stop failure would be
136 # crm_simulate -S --xml-file /tmp/memcached-test.xml
