From dbshow you will see if the Slave_IO isn’t running or if the flights tables are out of sync. Perform the following steps to get TDLS databases back in sync.

• Run service tdls stop on the standby server then on the active server
• Run the ‘config’ command from the server that shows the Slave_IO isn’t running or the one with less TDLS flights
• Input ‘8’ as the choice to copy complete configuration from the other server
• Run service tdls start on the server you wish to be active first, the on the other server
• Run dbshow again to verify databases are synced
