I am I bit confused about my Elasticsearch index. Some of the the indexes are turned into RED, while some are in Yellow status. I am suspecting the issue with unassigned_shards. Can anyone explain me is the Elasticsearch is running fine or the issue exists with unassigned_shards?
As per your suggestion, I checked the unassigned indices which are 8 primary and 624 replicas.
Whey should I worry when active_primary_shards and unassigned_shards numbers are high? Is there any algorithm to maintain proper cluster with number of nodes based on number of both indexes(primary/replica).
