Umbraco Lucene 索引设备未准备好
Umbraco Lucene Index Device not ready
所以我在 windows 共享主机上的 Umbraco 7 实例上遇到异常。似乎在任意时间后，Lucene 索引（我不直接调用其 API）出现问题并且应用程序进入错误状态，直到我刷新应用程序池。任何帮助将不胜感激。

Azure 网站使用远程文件系统，这可能会对 Lucene 造成严重破坏，我们已经多次看到此错误。我只能假设 Godaddy 也为其 IIS 网站使用远程文件服务器。
基本上解决方案是 运行 你的 Umbraco lucene 索引在本地临时 asp.net 存储上。在最新版本的 Umbraco (7.2.8+) 中，此功能内置于核心中，您可以为索引器和搜索器使用 LocalOnly 配置标志，例如：
<add name="InternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
supportUnpublished="true"
supportProtected="true"
analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"
useTempStorage="LocalOnly"/>
<add name="InternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"
useTempStorage="LocalOnly"/>
如果您使用旧版本的 Umbraco，您可以使用名为 TempStorage 的自定义库：https://github.com/Shazwazza/UmbracoExamine.TempStorage
