After preparing a slave server I have an error after a while running: Could not execute Update\_rows event on table tbl; Can’t find record in ‘tbl’, Error\_code: 1032; handler error HA\_ERR\_END\_OF\_FILE; the event’s master log mysql-bin.72142, end\_log\_pos 6387298 I don’t know what could be the problem. This master-slave configuration have been running for years without any problem in SBR mode and now is getting trouble changing to RBR. How to debug it ? ---

Your replica has different data than the master does. pt-table-checksum and pt-table-sync are your friends. ---

Yes, but why I have different data ? Someone is modifying data on slave server ? Is strange because is only for read, and replication is configurated with RBR mode fron scratch… I will configure slave server with read only mode to know if some of my developers is using it to modifying data …
