如何释放更多的空间

---

我想正常启动或提取数据库

鉴于rsyslog抱怨“设备上没有空间”，我怀疑mysql也会有同样的问题。它也需要空间来工作

journalctl -u mysqld.service

查看mysql错误，但由于空间不足，它的录制可能也很有限

---

修复存储上的可用空间量，让所有程序都满意。

hi，我添加了“journalctl-u mysqld.service”日志，即如何释放更多空间。

df-h

查看哪些文件系统空间不足。在那里查找您不需要的要删除的内容。不要删除mysql文件，否则它会崩溃。在unix.stackexchange.com/中搜索一般答案，并可能在那里使用

df-h

输出、您的

/etc/fstab

内容询问您的问题，如果您使用的是lvm

vgs-v；lvs-v

，并包括您的发行版和版本。

journalctl -u mysqld.service
