Cloning a cluster with EBS snapshots


I'm trying to clone my cluster to be able to test some Ansible scripts, I'm hosted on AWS with all data nodes having there own EBS drive.

I remade all the nodes, Master, Clients, and Data with EBS drives from snapshots. Reinstall Elasticsearch on all nodes and they are all online and green, but the indexes that are in the data path are not being loaded.

What am I doing wrong?
