Error message

no more logs

What it means

ErrNoMoreLogs is a sentinel error exported from helper/raftutil indicating the FSM helper has applied every available Raft log: nextIdx has passed logLastIdx. It is not a failure — ApplyUntil and ApplyAll treat it as the normal termination signal for replaying logs.

Solutions

1. Treat it as success: compare with errors.Is(err, raftutil.ErrNoMoreLogs) and stop the replay loop
2. No fix needed — this signals normal completion of log replay

Example fix

// before
idx, term, err := f.ApplyNext()
if err != nil { return err }
// after
idx, term, err := f.ApplyNext()
if errors.Is(err, raftutil.ErrNoMoreLogs) {
    return lastIdx, lastTerm, nil // replay complete
} else if err != nil {
    return err
}

func isNoMoreLogs(err error) bool { return errors.Is(err, raftutil.ErrNoMoreLogs) }

idx, term, err := f.ApplyNext()
if errors.Is(err, raftutil.ErrNoMoreLogs) {
    return lastIdx, lastTerm, nil // success: log exhausted
}
if err != nil {
    return err
}

When it happens

Trigger: Calling ApplyNext on an FSMHelper whose nextIdx exceeds the store's last log index; it is also returned by ApplyUntil and ApplyAll when replay reaches the end of the log.

Common situations: Tooling that replays a Nomad server's Raft log offline (debugging, migration, state inspection) reaching the end of the log; testing with TestSampleInvariant where replay exhaustion is expected.
