Ubuntu
設備錯誤上沒有剩餘空間
我無法再在我的數據庫中生成新列。我的堆棧在下面。我是管理自己的伺服器的新手，不熟悉 Apache、Ubuntu 和 AWS。目前我收到一條錯誤消息，提示我沒有空間了。
看起來我的文件夾 /dev/xvda1 的容量為 100%。如何確定空間分配方式以及如何打開更多空間？
如果你能幫助我分享什麼，我會熱切地分享更多資訊。

您必須探索您的 HDD 並清理過時和/或未使用的文件。
最簡單的方法是停止所有服務，如 postgres/apache/postfix 等（以防止數據失去）並探勘目錄大小。命令
du -d 1 | sort -nr列出目前位置的所有嵌套目錄及其大小。在某些迭代之後，您會找到太空販子，然後您將需要另一個建議 - 如何處理它們。
