根(/dev/vda1 1)上的空间不足。不知道为什么

Question

我有一个新的Ubuntu数字海洋液滴，它不断耗尽空间的根。

df

80g/分区是100%。

但是当我切换到/和做

du -sk -x -h *

我不能让它加起来超过几次演出。不知道整个80场演出都去哪了！

到目前为止，我尝试了几个恰当的干净命令，但这几乎没有什么区别。

这是一个更大的包裹清单，但我不确定哪些是安全的。

dpkg-query --show --showformat='${Package;-50}\t${Installed-Size}\n' | sort -k 2 -n | grep -v deinstall | awk '{printf "%.3f MB \t %s\n", $2/(1024), $1}'

当我这样做..。./mnt显示比它的大小更大，这是奇怪的(驱动器只有350次)。还有那些访问错误是怎么回事

sudo du -hd 1 | sort -h

以下是/mnt的内容。其中一些可能是本地文件吗？

首先，可以添加-x选项以防止du遍历文件系统。

然后添加sort -h按文件大小排序

最后，以root用户的身份运行此命令。

du -shx /* | sort -rh

这可以帮助您了解发生了什么，通过查看第一行，而不花费太多的时间探索您的/mnt。

您似乎还在/etc/文件上出现文件系统损坏。/etc/文件不太可能很大，但是您仍然可以在文件系统恶化之前检查它的错误。

如果您无法计算空间消耗，请在/etc/中运行相同的命令，这样您就可以知道它在没有损坏目录的情况下所需的大小。
