What happens on failover when cluster not in sync?

Hi Alexander,

Yes, the config that is not in sync will not be available on the standby device

Once failover happens the standby will resume the active role with last synchronized configuration, (other that the unsynchronized config all will work fine)

However in such situation to get the lost config on the Standby (now Active), you can do a config pull

GUI - System ›› High Availability : ConfigSync >> (Synchronize from peer)

CLI

Thanks
