High watermark exceeded - How to resync Elasticsearch?


#1

I had an issue where the disk that Elasticsearch was writing to was getting full.
I spotted that there were messages in elasticsearch logfile warning that the file system it was using was 90% full. (high disk watermark exceeded on ...) So I have moved /var/lib/elasicsearch to another partition with more space. I have restarted both elasticsearch and logstash but not seeing any more recent data. Do I have to do anything else to get it back working again?

Is there an easy way to tell if logstash and elasticsearch are collecting and storing data ok?

ES monitors the disk space every 30s, so cleaning up the disk should have worked. Did you actually run out of disk space? you can check the stats API and see if documents are being indexed (or install something like Marvel that will visualize it for you)
