Unanswered: Adding a Replication Slave without restarting the Database
Our production database is currently running with 1 master and 1 slave. We're experiencing some excessive load and would like to add an additional slave (either a slave to the master or a cascaded slave). It will be used as a readonly database only.
Is this process possible without taking the master or existing slave database offline? We'd rather not have an outage for this process.
