我从13.10升级了旧服务器 – > 14.04 – > 14.10 – >昨天15.10.今天我看到100％的磁盘空间正在使用,但我无法追踪使用情况.
当我运行du -h –max-depth = 1 /我得到以下日志,这似乎表明根路径已满,但我不知道源是什么.

当我ls -la in /我看到这个：

再一次,没有看到使用磁盘空间的是什么.
我应该在这里做些什么步骤？
运行以下命令以查找可用磁盘空间信息：
df -h
然后运行以下命令以查找磁盘利用率信息：
sudo du -shc /
(注意sudo,这应该解决你看到的权限问题)
当您发现占用大量磁盘空间的目录时,请cd到目录并重复步骤#2.继续重复此步骤,直到找到磁盘空间问题的来源.
