如何从Mounting阶段恢复数据库

Question

我们正在使用MarkLogic服务器'7.0-2.3'，它有几个应用程序数据库。在我们的64位服务器上，RAM为16 GB，总可用空间为368GB，其中267 GB是免费提供的。

但我们仍然面临着Mounting问题。从最后3到4小时，它处于恢复模式。是否有任何方法可以帮助我们更快地恢复它而不会丢失任何文件。

我已经在WEB上搜索并找到了一些解决方案：

https://help.marklogic.com/knowledgebase/article/View/134/0/my-forests-are-taking-a-long-time-to-mount---what-should-i-do

但由于MarkLogic没有响应，我无法设置这些已定义的更改。

日志错误：

Answer 1

这很糟糕：

Warning: Missing journal file C:\Program Files\MarkLogic\Data\Forests\IETTV-Activity-Forest\Journals\Journal1-19861226230000-0-138399-0

这可能是文件系统损坏的结果，可能是坏磁盘甚至是坏内存。它不太可能是MarkLogic中的错误。所以我会查看操作系统日志，看看是否有任何相关错误。我还会运行一个完整的文件系统检查。

你有备份，对吧？

您可以与支持小组联系，了解他们是否可以提供帮助。他们可能会建议关闭服务器，然后从该林中删除Label和Journals。

但是，如果它是文件系统损坏或磁盘坏的低级问题，您可能会在其他磁盘结构中遇到错误。在这种情况下，您不太可能恢复数据。我预测，在解决任何可能出现的低级问题之后，你最终会清除森林。

最后 - 这可能与问题无关 - 我将升级到7.0-5以获取最新的错误修复：http://developer.marklogic.com/products/marklogic-server/7.0

Answer 2

＆＃34;折叠时间戳＆＃34;消息表明您在某个时间点为主机设置的日期非常不正确。

＆＃34;断开＆＃34;消息表明群集中存在网络问题，或者某些计算机未正常运行。
