Elasticsearch：安装bitnami/elasticsearch图表后获取节点锁失败

Question

我使用nfs-csi驱动程序成功为bitnami/kafka进行持久存储。 但这次我使用 nfs-csi 驱动程序对 bitnami/elasticsearch 进行持久化，但失败了。

$ kubectl  get sc
NAME                PROVISIONER       RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
nfs-csi (default)   nfs.csi.k8s.io    Delete          Immediate           false                  43d

安装图表

$ kubectl create ns elk2

$ helm pull  oci://registry-1.docker.io/bitnamicharts/elasticsearch


$ vim elasticsearch/values.yaml
global:
  imageRegistry: ""
  ## E.g.
  ## imagePullSecrets:
  ##   - myRegistryKeySecretName
  ##
  imagePullSecrets: []
  ### use the storageclass: nfs-csi
  storageClass: "nfs-csi"   
  elasticsearch:
    service:
      name: elasticsearch
      ports:
        restAPI: 9200
  kibanaEnabled: false

$ helm install elasticsearch ./ -f values.yaml -n elk2 


$ helm list -n elk2

ERROR: Elasticsearch did not exit normally - check the logs at /opt/bitnami/elasticsearch/logs/elastic.log

ERROR: Elasticsearch exited unexpectedly

我在日志中看到错误。但我不知道如何解决它。 nfs的权限没问题

对不起，我快绝望了。我花了好几天的时间来解决这个问题。我向 github 提交了问题，但尚未得到回复。

我也遇到同样的错误。

我通过添加 volumePermissions.enabled: "true" 解决了这个问题，如此评论所示 https://github.com/bitnami/charts/issues/17834#issuecomment-1776865043 .
