76 Once we start and do some basic sanity checks, we go into the
77 S_NOT_DC state and await instructions from the DC or input from
78 the cluster layer which indicates the election algorithm needs to run.
79
80 If the election algorithm is triggered, we enter the S_ELECTION state
81 from where we can either go back to the S_NOT_DC state or progress
82 to the S_INTEGRATION state (or S_RELEASE_DC if we used to be the DC
83 but aren't anymore). See the libcrmcluster API documentation for more
84 information about the election algorithm.
85
86 Once the election is complete, if we are the DC, we enter the
87 S_INTEGRATION state which is a DC-in-waiting style state. We are
88 the DC, but we shouldn't do anything yet because we may not have an
89 up-to-date picture of the cluster. There may of course be times
90 when this fails, so we should go back to the S_RECOVERY stage and
91 check everything is ok. We may also end up here if a new node came
92 online, since each node is authoritative about itself, and we would want
93 to incorporate its information into the CIB.
94
95 Once we have the latest CIB, we then enter the S_POLICY_ENGINE state
96 where invoke the scheduler. It is possible that between
97 invoking the scheduler and receiving an answer, that we receive
98 more input. In this case, we would discard the orginal result and
99 invoke it again.
100
101 Once we are satisfied with the output from the scheduler, we
102 enter S_TRANSITION_ENGINE and feed the scheduler's output to the
103 Transition Engine who attempts to make the scheduler's
104 calculation a reality. If the transition completes successfully,
105 we enter S_IDLE, otherwise we go back to S_POLICY_ENGINE with the
106 current unstable state and try again.
107
108 Of course, we may be asked to shutdown at any time, however we must
109 progress to S_NOT_DC before doing so. Once we have handed over DC
110 duties to another node, we can then shut down like everyone else,
111 that is, by asking the DC for permission and waiting for it to take all
112 our resources away.
113
114 The case where we are the DC and the only node in the cluster is a
115 special case and handled as an escalation which takes us to
116 S_SHUTDOWN. Similarly, if any other point in the shutdown
117 fails or stalls, this is escalated and we end up in S_TERMINATE.
118
119 At any point, the controller can relay messages for its subsystems,
120 but outbound messages (from subsystems) should probably be blocked
121 until S_INTEGRATION (for the DC) or the join protocol has
122 completed (for non-DC controllers).
