Hi,
I'm looking for a way to prevent the loss of shard data piled up during ES shutdown.
Is this document relevant? ↓
'Cluster Reroute' >> 'Retry failed shards'
(https://www.elastic.co/guide/en/elasticsearch/reference/5.0/cluster-reroute.html#_retry_failed_shards)
This document is too short.
What exactly is this document about?
And, how do you use it?
