52       -S, --simulate
53              Like --run, but also simulate taking those actions and show  the
54              resulting new status
55
56       -X, --in-place
57              Like  --simulate,  but  also store the results back to the input
58              file

71
72       -P, --profile=DIR
73              Process all the XML files in the named directory to create  pro‐
74              filing data
75
76       -N, --repeat=N
77              With --profile, repeat each test N times and print timings
78
79   Synthetic Cluster Events:
80       -u, --node-up=NODE
81              Simulate bringing a node online
82
83       -d, --node-down=NODE
84              Simulate taking a node offline
85
86       -f, --node-fail=NODE
87              Simulate a node failing
88
89       -i, --op-inject=OPSPEC
90              Generate  a  failure  for the cluster to react to in the simula‐
91              tion.  See `Operation Specification` help for more information.
92
93       -F, --op-fail=OPSPEC
94              If the specified task occurs during the simulation, have it fail
95              with  return  code  ${rc}.  The transition will normally stop at
96              the failed action.   Save  the  result  with  --save-output  and
97              re-run  with --xml-file.  See `Operation Specification` help for
98              more information.
99
100       -t, --set-datetime=DATETIME
101              Set      date/time       (ISO       8601       format,       see
102              https://en.wikipedia.org/wiki/ISO_8601)
103
104       -q, --quorum=QUORUM
105              Set to '1' (or 'true') to indicate cluster has quorum
106
107       -w, --watchdog=DEVICE
108              Set  to '1' (or 'true') to indicate cluster has an active watch‐
109              dog device
110
111       -g, --ticket-grant=TICKET
112              Simulate granting a ticket
113
114       -r, --ticket-revoke=TICKET

118              Simulate making a ticket standby
119
120       -e, --ticket-activate=TICKET

138              transition)
139

OPERATION SPECIFICATION

161       The   OPSPEC   in  any  command  line  option  is  of  the  form  ${re‐
162       source}_${task}_${interval_in_ms}@${node}=${rc}        (memcached_moni‐
163       tor_20000@bart.example.com=7,  for  example).   ${rc}  is an OCF return
164       code.   For  more  information  on  these  return   codes,   refer   to
165       https://clusterlabs.org/pacemaker/doc/2.1/Pacemaker_Administra
166       tion/html/agents.html#ocf-return-codes
167

EXAMPLES

169       Pretend a recurring monitor action  found  memcached  stopped  on  node
170       fred.example.com  and,  during recovery, that the memcached stop action
171       failed:
172
173              crm_simulate -LS --op-inject  memcached:0_monitor_20000@bart.ex‐
174              ample.com=7    --op-fail   memcached:0_stop_0@fred.example.com=1
175              --save-output /tmp/memcached-test.xml
176
177       Now see what the reaction to the stop failed would be:
178
179              crm_simulate -S --xml-file /tmp/memcached-test.xml
