If you are facing issues with replication on our system, this guide will help you identify common problems and their solutions. Before proceeding, please ensure you have reviewed the basic replication setup and configuration as described in the Replication Configuration.

Common Replication Issues

  1. Data Synchronization Delay

    • Cause: The delay can be due to network issues, high load on the server, or improper configuration.
    • Solution: Check the network connection and server load. Adjust the replication parameters such as replication_timeout and replication_lag_time.

  2. Failed Replication

    • Cause: This could be due to incorrect replication setup, missing permissions, or corruption in data files.
    • Solution: Verify the replication setup, ensure the user has the necessary permissions, and check for any corruption in the data files using tools like mysqlcheck.

  3. Inconsistent Data

    • Cause: Inconsistent data might occur if the master and slave servers are not in sync due to network or server errors.
    • Solution: Reinitiate the replication process using RESET SLAVE; and start the replication again with START SLAVE;.
