Question

我们有运行rabbitmq 3.5.6的服务器，它在一个点上运行到磁盘已满。

服务器有问题，所以我们尝试将文件从mnesia文件夹复制到另一台也有rabbitmq的服务器。我们在新服务器上更改了所需的内容，以匹配前一个主机名。

我们尝试使用来自几个崩溃服务器的文件，我们可以恢复队列消息。

但是对于其他一些人来说，当我运行服务rabbitmq-server start命令时，它似乎无法做到并且只是挂起或冻结。基于rabbit@host.log，似乎可能存在一些解析段问题。

但它会在vhost'/'中提及重启崩溃队列'点击'。并且要么花了太长时间（不知道它是否卡住），否则它会再次重复某些行并重新启动崩溃的队列。

任何帮助将不胜感激。感谢。

这是我们从服务器启动时的日志...

Answer 1

我们发现这个工具能够读取rabbitmq队列idx文件和持久存储rdq文件。然后我们能够将这些数据一次性重新导入rabbitmq一条消息，让我们的消费者正常处理数据。
