There are many posts in the community about how to clear high watermarks from Elasticsearch… here is an Elasticsearch article that addresses some of the issue as well You didn’t post what version of elasticsearch you are on so I chose randomly to get you started. You can also find people asking and getting replies on how to move data out (archive) of Elasticsearch or out on the internet on how to properly increase disk spaces based on your configuration. Use the search, Luke!
