Now that you kind people have pointed me in the right direction as far as log-bin was concerned, I've moved on to trying to replicate the databases from the primary to the secondary. I've created the connection profile and started the secondary connection, but when I ran show slave 'master01' status\G I got the following error: Last_Errno: 1062 Last_Error: Could not execute Write_rows_v1 event on table databasename.oc_filecache; Duplicate entry '110' for key 'PRIMARY', Error_code: 1062; handler error HA_ERR_FOUND_DUPP_KEY; the event's master log master-bin.00000#, end_log_pos ###### How do I resolve this duplicate entry error? And do I need to do the same resolution on the primary as well?
