我在我的grails 1.3.7项目中使用的是searchable插件。我的项目运行得很好，直到我的macbook硬盘满了，osx抛出了一个关于内存问题的消息，它会删除一些文件(tmp等)(在那之后，我删除了一些电影，得到了超过10GB的可用空间)。我没有改变源代码，但当我现在启动我的grails应用程序时，我得到以下异常:

我认为在文件系统中lucene索引有问题，但我在哪里可以找到它?lucene索引文件夹或文件存储在哪里?我没有更改插件的配置
根据默认的配置文件
/**
* The location of the Compass index
*
* Examples: "/home/app/compassindex", "ram://app-index" or null to use the default
*
* The default is "${user.home}/.grails/projects/${app.name}/searchable-index/${grails.env}"
*/
所以除非你改变了它(你说你没有)，否则我会在
中查看一下。~/.grails/projects/${app.name}/searchable-index/${grails.env}
我的tomcat安装在${user.home}/.grails/projects/${app.name}/search_index目录下，请记住tomcat进程可能是在不同的用户下运行的，所以我运行"sudo nautilus"来查看它
看起来像是某种Unix/OS X权限问题。当Searchable/Lucene启动并尝试创建索引时，它做的第一件事是在索引目录中创建一个锁文件。从堆栈跟踪来看，这就是失败的地方。
Searchable.groovy文件是定义索引路径的地方;它有可能在environment块中被覆盖，甚至可能在Config.groovy中被覆盖。
grails run-app作为您的用户运行Grails，因此问题与Tomcat作为不同用户运行无关。
