MariaDB 10.3.39启动失败求助

各位大佬好，我这边MariaDB 10.3.39一直启动失败，查了systemd的日志后看到了这些错误信息，想请教下大家问题出在哪，该怎么解决？

Apr 15 15:21:23 ceph3 systemd[1]: mariadb.service: Main process exited, code=exited, status=1/FAILURE
Apr 15 15:21:23 ceph3 systemd[1]: mariadb.service: Failed with result 'exit-code'.

我自己看日志发现两个关键点：

• 一个警告：没法把max_open_files提升到请求的36143，最多只能到32768
• 一个致命错误：Unknown collation: 'utf9_general_ci'，之后进程直接中止了

我感觉collation的问题应该是启动失败的核心原因，但不知道这个utf9_general_ci是哪里来的，也不清楚怎么修复。另外那个文件数的警告会不会也有影响？有没有懂的朋友给指点下？
