I am facing an issue with ES where it shows 174 shards are unassigned. and allocate_explanation is :"cannot allocate because all found copies of the shard are there stale or corrupt".
This issue is arising since yesterday, when we restarted the Master node. Can somebody suggests on the same.
I tried reducing the number of replicas for the index from 3 to 1 but it doesn't work. DO i need to run "cluster.routing.allocation.enable":"all" or if any other suggestions are there plz share.
