Greetings,
After setting up a second slave as a replica following this thread How to setup a replica for replication in 6 simple steps with Percona XtraBackup I have encountered some issues.
I have followed the procedures as described in “Adding more replicas to the Source” .
I am currently running a master as mysql5.6 and already have a salve replicating from it with mysql5.6.
now… I have added an additional slave with mysql5.7 and was surprised to find the following errors in the log.
2022-12-24T12:01:55.915669Z 0 [ERROR] InnoDB: Table `mysql`.`innodb_table_stats` not found.
2022-12-24T12:01:55.915688Z 0 [Warning] InnoDB: Recalculation of persistent statistics requested for table `database`.`table` but the required persistent statistics storage is not present or is corrupted. Using transient stats instead.
Does anyone have an idea as to what can cause these errors?
is it because I have added the additional slave with mysql5.7?
