在OpenShift上的MongoDB：/data/db/mongod.lock资源暂时不可用。

Question

在OpenShift上的MongoDB：/data/db/mongod.lock资源暂时不可用。

4

每次在OpenShift上部署MongoDB时，我都会收到如下错误信息：

exception in initAndListen: 98 Unable to lock file: /data/db/mongod.lock Resource temporarily unavailable. Is a mongod instance already running?, terminating

。容器基于mongo:3.4，并将/data/db挂载为卷。

我尝试按照What is the use of the mongo.lock file?建议删除 /data/db/mongod.lock文件，但这没有起作用-现在我遇到了关于WiredTiger的错误。

有什么想法可以使它正常工作吗？

以下是删除/data/db/mongod.lock后出现问题的日志。

这是 MongoDB 容器的配置

- image: 'mongo:3.4'
  command:
    - sh
  args:
    - '-c'
    - rm -f /data/db/mongod.lock; mongod --dbpath /data/db --repair; mongod --dbpath /data/db
  volumeMounts:
    - mountPath: /data/db

首先，阅读此文以了解OpenShift如何终止容器：https://pracucci.com/graceful-shutdown-of-kubernetes-pods.html。

我已删除了/data/db中的所有内容，然后更新了容器配置。

- image: 'mongo:3.4'
  command:
    - /bin/bash
  args:
    - '-c'
    - rm -f /data/db/mongod.lock /data/db/WiredTiger.lock; mongod
  volumeMounts:
    - mountPath: /data/db

之前的一系列测试部署都成功了。但在之后的几次部署中又开始出现问题，这一次是带有以下错误信息：

在我的情况下，它会出现以下错误信息： IllegalOperation: 尝试在只读目录 /data/db 上创建锁文件。
