标题: 如何查找占用根目录的文件
CentOS 6.4做WEB服务，才用三个月却发现根目录占用异常，怎么能找出被占用的目录？

14G都在/usr目录下，不是挺明显么

不会又是nas mount点的问题吧?

问题是有38GB被占用，Usr用14GB是正常的，跟下的15GB让谁占用的，另外还有近10个GB找不到了。

lsof /tmp 看一下.

如果你发现有 (delete) 的文件, 并且, 尺寸较大. 那你可能要重启一下访问这个文件应用了.

怎么根本没有使用 /tmp ...

那可能是其它的文件了. lsof | grep delete 找一下吧.

有没有以点开头的隐藏文件夹？

CentOS 6.4做WEB服务，才用三个月却发现根目录占用异常，怎么能找出被占用的目录？

也可能是文件系统坏了，可以重启看看。

目测是你这些log了.

看来, 你的java应用要停一下了.

怎么根本没有使用 /tmp ...

那可能是其它的文件了. lsof | grep delete 找一下吧.

非常感谢！我直接echo > /proc/2606/fd/7

现在正常了

你不会是没有停java应用, 就把 log 给删了吧?

Java不能停，网站需要7*24小时运行。所以有时候需要手动优化跟手动清理日志。

你的主要问题是java在使用完日志之后, 没有关闭 fd, 所以, 这些日志对于java来说, 一直是 "打开"状态, 所以, 就算你在目录里删除了这些文件, 它们也不会从磁盘上清理掉. 只有所有的引用 fd 被关闭, 才会清空这些文件.

那如何在不停止Java服务的前提下关闭fd，并清理日志？

这个要修改代码的. 因为你的代码里没有关闭这些fd, 现在只有重启java才能关闭. 因为java不支持 kill -HUP.
