## Liveness probe

This probe always responds with '200 OK'. Only fails if 'etcd' is configured and unreachable. When liveness probe fails, Kubernetes like platforms restart the container.

```
livenessProbe:
  httpGet:
    path: /minio/health/live
    port: 9000
    scheme: HTTP
  initialDelaySeconds: 120

		return ctx, done, ctx.Err()
	}

	atomic.StoreInt64(&p.health.lastStarted, time.Now().UnixNano())
	p.health.waiting.Add(1)

	ctx = context.WithValue(ctx, healthDiskCtxKey{}, &healthDiskCtxValue{lastSuccess: &p.health.lastSuccess})
	si := p.updateStorageMetrics(s, paths...)
	var once sync.Once
	return ctx, func(sz int64, errp *error) {
		p.health.waiting.Add(-1)
		once.Do(func() {
			if errp != nil {

  // `nonResourceURLs` is a set of url prefixes that a user should have access to and may not be empty.
  // For example:
  //   - "/healthz" is legal
  //   - "/hea*" is illegal
  //   - "/hea" is legal but matches nothing
  //   - "/hea/*" also matches nothing
  //   - "/healthz/*" matches all per-component health checks.
  // "*" matches all non-resource urls. if it is present, it must be the only entry.
  // +listType=set
  // Required.

- During device plugin allocation, resources requested by the pod can only be allocated if the device plugin has registered itself to kubelet AND healthy devices are present on the node to be allocated. If these conditions are not sattsfied, the pod would fail with `UnexpectedAdmissionError` error.
