Hi All, A while ago I reported this issue, but back then I was running a single node cluser and though that may have been the issue. Yesterday I migrated to a triple node cluster configuration: 3 elasticsearch nodes (master and data nodes) 1 logstash 1 kibana 5 filebeats. Everything is running…

I tried, this time the file was missing. Then the cluster was restarted and when it came back the index was working like nothing happened. There is something very fishy here. I will continue trying to diagnose the FS

I see a previous post from you about the same sort of issue here:

Did you try the same diagnosis steps as before? I.e. does ls /usr/share/elasticsearch/data/nodes/0/indices/50zRNBhxT3qdJpUdS4B47Q/0/index/ show a file called _1a4.fdt but ls /usr/share/elasticsearch/data/nodes/0/indices/50zRNBhxT3qdJpUdS4B47Q/0/index/_1a4.fdt reports No such file or directory? If so there's something fundamentally wrong with your filesystem again.
