我无法再在数据库中生成新列。我的堆栈如下。我是管理自己的服务器的新手，不熟悉 Apache、Ubuntu 和 AWS。目前我收到一条错误消息，提示我没有剩余空间。
看起来我的文件夹 /dev/xvda1 的容量已达到 100%。如何确定空间是如何分配的以及如何开辟更多空间？
如果您能帮助我分享更多信息，我将非常乐意与您分享。

您必须探索您的硬盘并清理过时和/或未使用的文件。
最简单的方法是停止所有服务，如 postgres/apache/postfix 等（以防止数据丢失），然后深入研究目录大小。命令
du -d 1 | sort -nr
列出当前位置的所有嵌套目录及其大小。经过一定次数的迭代后，您将发现空间贩子，然后您将需要另一条建议 - 如何处理它们。
