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

时间：2019-03-15 12:32:13

标签： mongodb openshift

在OpenShift上重新部署MongoDB时，我不断得到exception in initAndListen: 98 Unable to lock file: /data/db/mongod.lock Resource temporarily unavailable. Is a mongod instance already running?, terminating。该容器基于mongo:3.4，并且/data/db作为卷安装。

我尝试删除/data/db/mongod.lock，建议由 What is the use of the mongo.lock file?。无济于事-现在我遇到关于WiredTiger的错误。

有什么主意要怎么做吗？

以下是删除/data/db/mongod.lock

后出现的问题的日志

这是MongoDB容器配置

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

我已删除/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

所有测试部署均成功。再经过几次部署后，这次又开始失败了，
