In this case, **Flood Stage Watermark is indicating a major disk space issue**, 3 watermarks are related to that: low: 85% of disk usage (default) high: 90% of disk usage (default) flood_stage: 95% of disk usage (default) <- critical All watermarks can be verified running a GET requests to the cluster: curl -X GET -H "Content-Type: application/json" http://[ENDPOINT]:9200/_cluster/settings?include_defaults=true When the last threshold or watermark is reached, ElasticSearch will force read-only mode.
