I am running Elastic Search 6.2.4 on a 150 GB virtual machine. The disk is 31% utilized which means more than 100 GB is free.

I keep seeing these messages on the elastic search logs files.
[2019-01-07T14:59:58,596][INFO ][o.e.c.r.a.DiskThresholdMonitor] [JUz2YCv] low disk watermark [85%] exceeded on [JUz2YCvyRxi-qrtqrO3Z0A][JUz2YCv][/var/lib/elasticsearch/nodes/0] free: 5.2gb[10.5%], replicas will not be assigned to this node
I have not done any specific cluster settings in Elastic Search.
Could someone help me why I am seeing this issue?
