We are running MySQL 3.23 in production, and have replication setup in the following manner: There are two machines (m1 and m2). Replication is setup in a circular way. Both machines are master and slave, more specifically, m1 is master to m2 and m2 is master to m1. I checked today and saw that one of the machines had a bunch of binary log files (see below). I read in the MySQL documentation that you can delete the logs by issuing a RESET MASTER command. I am wonder how this will affect replication. Is this going to break replication in any way? Is it safe to simply delete the binary log files manually ? (Id prefer to do this). Any input would be helpful.
Thank you.
