I have 4 instances. One of the instance has 3 nodes like below and others has only one node.
Instance 2, Instance 3 and instance 4 has like below:
Can anyone tell me why Instance1 has multiple nodes? What does it means?
if I run the _nodes/stats/fs api, it's just showing only this path /var/lib/elasticsearch/elasticsearch/nodes/0 for instance1. Why its not showing for nodes/1 and nodes/2?
ES version - 2.3.3
Sometimes back, disk for instance1 got full.
