To be sure that in case replication were to start I set the MASTER parameters to be wrong so the replication would not work. After doing this, even if I ran STOP SLAVE
and STOP SLAVE SQL_THREAD;
the server kept trying to restart replication, causing the log file to fill up.
The only way to get through MySQL's head that I wanted replication to stop was to follow the suggestion in How do I completely disable MySQL replicationHow do I completely disable MySQL replication and stop the mysql service and delete the master.info
and relay-log.info
files.
