I have 4 nodes running 5.3 with x-pack & ssl  
I notice this [INFO] on only one of the node which has 147GB that's the smallest disk in the custer - the other nodes have 400+ GB

`[2017-04-01T23:15:26,555][INFO][o.e.c.r.a.DiskThresholdMonitor] [SERVERNAME] low disk watermark [85%] exceeded on [jU_BWNxLQGyUkWL42ZRYIQ][SERVERNAME][/appl/elasticsearch/nodes/0] free: 147.1gb[14.9%], replicas will not be assigned to this node`

Where can I modify this setting? I have a trivially small amount of data like 1gb

**_Is some "check" thinking ahead anticipating there wont enough room in the future on the low disk?_**

Id like to increase this threshold so I can utilize what disk I have

Thanks  
Bob
