我们试图使用nfs provisioner在kubernetes上运行kafka集群。集群出现得很好。然而，当我们杀死一个Kafka吊舱时，替换吊舱却没有出现。
pod删除前的持久卷：

# mount

# cat /opt/kafka/data/logs   /meta.properties

删除pod：

kubectl delete pod kafka-iced-unicorn-1

新创建的pod中重新连接的持久卷：

# ls -al /opt/kafka/data/logs

我们在Kafka日志中看到以下错误：

解决这个问题的唯一方法似乎是删除持久卷声明并再次强制删除pod。或者使用nfs以外的另一个存储提供程序（rook在这种情况下运行良好）。
是否有人在nfs provisioner中遇到此问题？
