你好，我正在我的 debian 机器上使用 debian 容器运行 openVZ，但现在我无法运行 apache，因为没有剩余空间。
我检查了df -h哪些分区已满，这是一个输出：

我不明白，为什么/dev/disk/by-uuid/光盘已满，因为只有一个 error.log 文件，其大小为 0b...
您能给我一个建议，哪个磁盘或分区可以满吗？因为在虚拟机上我有 50% 的可用空间......
答案1
我无法评论我的声誉，但 Michal 似乎你已经通过 lsof 找到了答案。 Cron 正在保存一个已删除的文件。您可以使用 pid 杀死 cron，如下所示：
sudo kill -9 235668
否则你可以清空文件描述符，如下所示：
> /proc/235668/fd/5 " or "> /var/lib/vz/root/102/tmp/tmpfzr8ypz
答案2
使用以下命令查找最大的文件并确定它是否有用，否则 rm 它。您可以在命令中更改以下文件的大小。另外，为什么文件系统的输出会重复？
find / -xdev -size +100000 -exec ls -l {} \;
