我们已经使用 helm chart 部署了 loki。我有 loki 持久音量。我怎样才能弄清楚使用的架构配置是什么，以便我可以保留日志。图 loki-2.1.1
下面是 value.yaml

  auth_enabled: false
  limits_config:
    enforce_metric_name: false
    reject_old_samples: true
    reject_old_samples_max_age: 240h
  schema_config:
    configs:
    - from: 2018-04-15
      store: boltdb
      object_store: filesystem
      schema: v9
      index:
        prefix: index_
        period: 240h

livenessProbe:
  httpGet:
    path: /ready
    port: http-metrics
  initialDelaySeconds: 45
persistence:
  existingClaim: loki-pvc

podAnnotations:
  prometheus.io/scrape: "true"
  prometheus.io/port: "http-metrics"

podManagementPolicy: OrderedReady
readinessProbe:
  httpGet:
    path: /ready
    port: http-metrics
  initialDelaySeconds: 45

在 aws 中使用 pvc。Size=50GB 我更新了配置。当我运行它时，我在 loki pod 中看到以下错误。
