Re: master master replication - hostname change - slaves fails
I don't think you need to flush your bin logs. CHANGE MASTER TO MASTER HOST = 'hostname'; Look at this for more info at http://dev.mysql.com/doc/refman/5.0/en/change-master-to.html There is a lot more you can add to the statement. thanks but this gave me a very similar error - I forget now as i reinstalled from scratch. i now get this error 080522 13:49:34 [ERROR] Slave: Error 'Table 'db' already exists' on query. Default database: 'mysql' which to me is odd as i have the following in my my.cnf binlog-ignore-db=mysql so i would have thought it would not try and replicate that db ? Although i did not need that in my previous configuration.

Don't jump the gun to reinstall so fast, your last spot was easier to fix. i now get this error 080522 13:49:34 [ERROR] Slave: Error 'Table 'db' already exists' on query.

Although i did not need that in my previous configuration. Any thoughts ? Well if your master ever fails and you make the slave your new mater you will be missing your mysql database. User mostly will be missing, which might not be a big thing in your situation. Are there any other logs before and after? Mike
