First of all, I have searched and read every post about this, but I could not found anything in particulary.
It's been two months since I have integrated AWS ES service in my application, and three times happened this:
There is a time when the index start consuming all the disk space. The last time the index was about 30GB
AWS ES service config:
- Data node: 2
- Data node types: m3.medium.elasticsearch
- Dedicated master instance count: 3
- Dedicated master instance type: t2.small.elasticsearch.
- Capacity of each data node: 100GB.
- ES version: 2.3
The problem is that in less than thirty minutes one of the node free storage size went from 21 GB to 0 GB, we did not know how this happened.
I am thinking that a merge happened, but I am not sure. I have attached the a graph of the minimum free storage space
Thanks in advance!
