10

DESCRIPTION

12       crm_simulate - Tool for simulating the cluster's response to events

OPTIONS

15       -?, --help
16              This text
17
18       -$, --version
19              Version information
20

23
24       -V, --verbose

26
27   Operations:
28       -R, --run
29              Determine  the cluster's response to the given configuration and
30              status
31
32       -S, --simulate Simulate the  transition's  execution  and  display  the
33              resulting cluster status
34
35       -X, --in-place Simulate the transition's execution and store the result
36              back to the input file
37
38       -s, --show-scores
39              Show allocation scores
40
41       -U, --show-utilization Show utilization information
42
43       -P, --profile=value
44              Run all tests in the named directory to create profiling data
45
46   Synthetic Cluster Events:
47       -u, --node-up=value
48              Bring a node online
49
50       -d, --node-down=value
51              Take a node offline
52
53       -f, --node-fail=value
54              Mark a node as failed
55
56       -i, --op-inject=value
57              Generate a failure for the cluster to react to in the simulation
58
59              Value    is    of    the    form    ${resource}_${task}_${inter‐
60              val}@${node}=${rc}.     Eg.   memcached_monitor_20000@bart.exam‐
61              ple.com=7 For more information on OCF return  codes,  refer  to:
62              http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pace
63              maker_Explained/s-ocf-return-codes.html
64
65       -F, --op-fail=value
66              If the specified task occurs during the simulation, have it fail
67              with return code ${rc}
68
69              Value    is    of    the    form    ${resource}_${task}_${inter‐
70              val}@${node}=${rc}.  Eg. memcached_stop_0@bart.example.com=1
71
72       The transition will normally stop at the failed action.
73              Save the result with --save-output and re-run with --xml-file
74
75       -t, --set-datetime=value
76              Set date/time
77
78       -q, --quorum=value
79              Specify a value for quorum
80
81       -w, --watchdog=value
82              Assume a watchdog device is active
83
84       -g, --ticket-grant=value
85              Grant a ticket
86
87       -r, --ticket-revoke=value
88              Revoke a ticket
89
90       -b, --ticket-standby=value
91              Make a ticket standby
92
93       -e, --ticket-activate=value
94              Activate a ticket
95
96   Output Options:
97       -I, --save-input=value
98              Save the input configuration to the named file
99
100       -O, --save-output=value
101              Save the output configuration to the named file
102
103       -G, --save-graph=value
104              Save the transition graph (XML format) to the named file
105
106       -D, --save-dotfile=value
107              Save the transition graph (DOT format) to the named file
108
109       -a, --all-actions
110              Display all possible actions in the DOT graph -  even  ones  not
111              part of the transition
112
113   Data Source:
114       -L, --live-check
115              Connect to the CIB and use the current contents as input
116
117       -x, --xml-file=value
118              Retrieve XML from the named file
119
120       -p, --xml-pipe
121              Retrieve XML from stdin
122

EXAMPLES

124       Pretend  a  recurring  monitor  action  found memcached stopped on node
125       fred.example.com and, during recovery, that the memcached  stop  action
126       failed
127
128              #     crm_simulate     -LS     --op-inject     memcached:0_moni‐
129              tor_20000@bart.example.com=7           --op-fail            mem‐
130              cached:0_stop_0@fred.example.com=1    --save-output    /tmp/mem‐
131              cached-test.xml
132
133       Now see what the reaction to the stop failure would be
134
135              # crm_simulate -S --xml-file /tmp/memcached-test.xml
