After a hardware maintenance of the application servers on our farm, we started getting some Load Balancer Endpoint errors on the Search Service. I had this before with the User Profile Service and stopping/starting the service trough SP Management Shell resolved.
We tried the same approach with the Search Service on one of the servers with endpoint failures and the service didnt stop. Also on Central Admin it is displayed as Error Stopping. Only then I realized that we must remove the server from the Search Topology before stopping the service, as the error in Central Admin clearly states:
Invalid search service unprovisioning: application 'Enterprise Search Service Application' still has a ready component 'XXXXXXX' on server 'XXXXX'.
This server is in the search topology as a Crawl Component, along with another server, making it two servers exclusive for Crawl Component. If I remove the failing server from the search topology, will I lose any index or information regarding search? What is the impact of removing it?
