【问题描述】：
我有一个 3 节点 mariadb 集群 (ubuntu 16.0.4 MariaDB 10.3.7) 在其中一个节点上执行 systemctl restart mysql 我收到以下错误消息：
mariadb.services: Unit entered failed state.
systemctl status mysql 返回这个

非常感谢您对此提供的任何帮助。

【问题讨论】：
-
我知道您还不能获得 7 天的正常运行时间。
-
一天通常就足够了。
-
Galera 节点相距多远？ （Ping 时间和/或物理距离）
-
这是所有 QA\Test 环境。集群上没有流量，仅限于运行简单更新插入查询的几个测试人员。
-
所有 3 个节点都位于同一个网络上。
