Unexpected Redis schema version: "5" (expected "6")

I still dont know the difference between icingadb (feature), icingdb (module) [Icinga DB WEB], icingadb.service, icingadb-redis-server.service, icingadb-redis.service, redis.service.

is there any diference beween moduel:icingadb and the feature:Icingadb-web. And are those the reason for the redis crash (schema 5 expected 6)?

• icinga2 is the core, check execution engine
• icingadb like the history database, successor of ido/monitoring
• icingadb-web is the module for icingaweb2 to display the data from icingadb

and now the confusing part if you install icingadb-web, in icingaweb2 the module is called icingadb

• icinga2 executes the check
• icinga2 writes it to a database and redis using icingadb feature
• icingaweb2 has a module called icingadb (icingadb-web) which reads from the database and from redis

depending on your os preference you can use one of these excelent guides to get started:
