Google Search Appliance: Configuring GSA Mirroring
15
If the master Google Search Appliance fails and a replica search appliance is promoted to be the master,
do not directly add the former master node back as the master, because this will cause problems in the
mirroring configuration. If you need to use the former master search appliance as the master, add it as
a replica of the new master first. Wait until all index and configuration data are fully synchronized with
the new master node, and then you can add the search appliance as the master again.
