Syslog产生数百行

Question

我最近被提升为实验室管理员，因为我对linux最有经验。我的日志检查一直给我发电子邮件，其中有数百行来自我的syslog文件。它会不断重复，每次都会有细微的变化。我不知道它想告诉我什么。有什么想法吗？这里有一个重复的片段：

你看到的是一堆痕迹。这是来自内核的一个未处理的错误，它显示了执行的路径，当某些事情发生严重的错误时，除了记录问题并留给人类去解决之外，没有其他的事情可做。

在头部的呼叫通常是决定性的：

WARNING: at /build/buildd-linux-2.6_2.6.32-45-amd64-FcX7RM/linux-2.6-2.6.32/debian/build/source_amd64_none/fs/fs-writeback.c:588 writeback_inodes_wb+0x36b/0x4ff()

fs-writeback：这是写到一个文件系统。正如在对您的问题的评论中指出的那样，您的磁盘上可能有错误。首先，我使用只读挂载和运行fsck的方式使机器进入单用户模式。
