Question

希望有人能帮助我：

我有我的服务器上运行的许多网站和我使用MariaDB的。 当我这样做：

我得到：

error code. See "systemctl status mariadb.service" and "journalctl -xe"

我真的不想失去我的分贝。 接下来应该做什么？

见第一个文件系统（的/ dev /根）为100％满！除了tmpfs卷之外，还没有安装其他卷。所以mariadb试图在启动时向磁盘写入内容，但不能，所以它放弃并关闭。

你必须弄清楚什么是填满你的磁盘，并修剪你可以。例如，作为一个猜测，我首先查看http服务器日志，因为你说你在这个服务器上托管了很多站点。我看到许多服务器通过让httpd将所有内容记录几个月，几个月来填满磁盘空间。

将来，您可能希望为该服务器配置多个磁盘卷，因此如果一个卷填满，它不会干扰其他卷。

还考虑自动化日志旋转。

如果磁盘空间使用的罪魁祸首不是日志，而实际上是mariadb数据目录，那么您可能需要立即获取额外的磁盘卷，并将mariadb内容移动到它，然后才能使您的网站重新联机。

除非您可以在服务器的其他地方找到一些其他地方的东西，您可以在短时间内删除并留出足够的空间。
