5.8.6版本如何开启会话持久化功能？

EMQX 功能请求
1

在emqx.conf配置文件中，新增了如下代码配置：
durable_sessions {
enable = true
}

重启后失败，报如下错误：

搞点emqx的日志看看

在/var/log/emqx/emqx.log.1查看的所有日志，看不出来啥，看着跟持久化相关的没有

先不要用systemd启动，用emqx console启动看看报什么错

持久化的集群功能是企业版功能，你开不动。单个节点就行。你改一下cluster strategy 变成singleton

7

cluster {
name = emqxcl
discovery_strategy = singleton
}

是这样就可以吗？这样改完就开启会话持久化了吗？
