我的neo4j-2.3.2社区数据库磁盘空间不足（80G）。我做了一个干净的关闭它，然后添加了更多的磁盘，并尝试重新启动它，只是为了得到神秘的错误消息，让它拒绝启动。
今天早上当我意识到磁盘已满并且它不再接受任何插入时，我把它关闭了。我没有回到试图把它带回来直到今晚。我为停机和重启之间的日志中的明显差距道歉。数据库仍处于原型/概念验证阶段。在过去一周左右的时间里，我一直在运行工作来加载数据。我真的，真的不想重新开始这个数据加载过程。它太慢了。
我希望有人会告诉我有一个＆＃34; neo4j --force_repair＆＃34;一种命令行选项，可以解决这个问题。我的数据加载器非常智能，可以在尝试加载新记录之前检查它在数据库中成功插入的最后记录，所以如果我们丢失了一些记录就应该没问题。
这是我在console.log中看到的内容。

这看起来只是部分写入了事务日志。如果这是真的，那么数据存储本身不太可能被破坏。
警告：在对data/graph.db文件夹进行任何手动更改之前，请务必准备好备份副本。
在继续之前，请阅读上一段。备份采取？如果是，请尝试按data/graph.db删除rm neostore.transaction.db.*中的事务日志文件。尝试启动Neo4j。如果仍然无法启动，请粘贴一个包含最新启动顺序的data/graph.db/messages.log代码段 - 这样可以提供更多洞察力。
