You can restore C and D from zero without having to shut off A (master server).

Just make a backup using --master-data=2 option

mysqldump -u MyUser -p --opt --master-data=2 --routines --databases MyDatabase > /pathtobackup/backup.sql


(During th backup the server will be up but the DB will be locked (all transactions will be processed after finish automatically.

That backup.sql contains a magic value... If you open it, will see the following line:

-- CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000008', MASTER_LOG_POS=829650236;


So that's the magic, just restore that backup in C and set the master values as pointed.


Repeat from C to D.
