Redirected from 2. References/Manager for MySQL Runbook/MySQL Problem Scenarios/Scenario 3 - The slave DB instance has failed

The Slave-DB instance failed

Recovering from a slave failure is as easy as launching a new slave template and initialize it from the
existing master.

Verification: how do I know my system is in this situation?

  1. Access the "active instances" (Manage -> Servers)
  2. Verify that none of the running instances derive from the slave template (i.e., click on each instance and check that it's template field is not Slave MySQL v?).

Required actions: What recipes should I apply to solve the situation?

  1. Launch a new slave DB
  2. Initialize slave DB from master DB
