If the election algorithm is triggered, we enter the S_ELECTION state from where we can either go back to the S_NOT_DC state or progress to the S_INTEGRATION state (or S_RELEASE_DC if we used to be the DC but aren't anymore). See the libcrmcluster API documentation for more information about the election algorithm. Once the election is complete, if we are the DC, we enter the S_INTEGRATION state which is a DC-in-waiting style state. We are the DC, but we shouldn't do anything yet because we may not have an up-to-date picture of the cluster. There may of course be times when this fails, so we should go back to the S_RECOVERY stage and check everything is ok. We may also end up here if a new node came online, since each node is authoritative about itself, and we would want to incorporate its information into the CIB. Once we have the latest CIB, we then enter the S_POLICY_ENGINE state where invoke the scheduler. It is possible that between invoking the scheduler and receiving an answer, that we receive more input. In this case, we would discard the orginal result and invoke it again. Once we are satisfied with the output from the scheduler, we enter S_TRANSITION_ENGINE and feed the scheduler's output to the Transition Engine who attempts to make the scheduler's calculation a reality. If the transition completes successfully, we enter S_IDLE, otherwise we go back to S_POLICY_ENGINE with the current unstable state and try again. Of course, we may be asked to shutdown at any time, however we must progress to S_NOT_DC before doing so. Once we have handed over DC duties to another node, we can then shut down like everyone else, that is, by asking the DC for permission and waiting for it to take all our resources away. The case where we are the DC and the only node in the cluster is a special case and handled as an escalation which takes us to S_SHUTDOWN. Similarly, if any other point in the shutdown fails or stalls, this is escalated and we end up in S_TERMINATE. At any point, the controller can relay messages for its subsystems, but outbound messages (from subsystems) should probably be blocked until S_INTEGRATION (for the DC) or the join protocol has completed (for non-DC controllers). */ /*====================================== * * Inputs/Events/Stimuli to be given to the finite state machine * * Some of these a true events, and others are synthesised based on * the "register" (see below) and the contents or source of messages. * * The machine keeps processing until receiving I_NULL * *======================================*/ enum crmd_fsa_input { /* 0 */ I_NULL, /* Nothing happened */ /* 1 */ I_CIB_OP, /* An update to the CIB occurred */ I_CIB_UPDATE, /* An update to the CIB occurred */ I_DC_TIMEOUT, /* We have lost communication with the DC */ I_ELECTION, /* Someone started an election */ I_PE_CALC, /* The scheduler needs to be invoked */ I_RELEASE_DC, /* The election completed and we were not * elected, but we were the DC beforehand */ I_ELECTION_DC, /* The election completed and we were (re-)elected * DC */ I_ERROR, /* Something bad happened (more serious than * I_FAIL) and may not have been due to the action * being performed.
