Let's say we have three MySQL servers, mysql1, mysql2 and mysql3. Replication is set up such that mysql3 is the slave of mysql2, and mysql2 is the slave of mysql1.
At some point I take a dump of mysql2 and record the binlog file and position of it by running show master status;. Is there a way to find the equivalent binlog file and position on mysql1 - for example so that I could load up the dump and continue replicating from mysql1 instead of mysql2?
