DiskThresholdMonitor low disk watermark [85%] exceeded replicas will not be assigned to this node

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
