The customer has an indexer cluster supporting a wide variety of search needs, including scheduled search, data model acceleration, and summary indexing. Here is an excerpt from the cluster mater’s server.conf:
Which strategy represents the minimum and least disruptive change necessary to protect the searchability of the indexer cluster in case of indexer failure?
- Enable maintenance mode on the CM to prevent excessive fix-up and bring the failed indexer back online.
- Leave replication_factor=2, increase search_factor=2 and enable summary_replication.
- Convert the cluster to multi-site and modify the server.conf to be site_replication_factor=2, site_search_factor=2.
- Increase replication_factor=3, search_factor=2 to protect the data, and allow there to always be a searchable copy.
