Start from zero with a new cluster

Hi all,

I've been working with this ELK solution for a few years and I can't restart all the nodes in a cluster to ... start from zero with a new cluster

1st - Delete all stored data

I can delete indexes ... (from command line)

curl -X DELETE "node: port / index_name"

for example a full erase

curl -X DELETE "192.168.72.10:9200/*"

2nd - Configure a new cluster - clean

My new cluster

Node: prso-home-1 (192.168.72.4)

cluster.name: PRSO_2021

node.name: prso-home-1

node.ingest: true

node.data: true

node.master: true

path.data: / var / lib / elasticsearch

path.logs: / var / log / elasticsearch

network.host: 192.168.72.4

discovery.seed_hosts: ["192.168.72.4", "192.168.72.5", "192.168.72.10", "192.168.72.20"]

cluster.initial_master_nodes: ["prso-elk-viten-1", "prso-home-1", "prso-elk-dm-1"]

Node: prso-elk-dm-1 (192.168.72.10)

cluster.name: PRSO_2021

node.name: prso-elk-dm-1

node.ingest: true

node.data: true

node.master: true

path.data: / var / lib / elasticsearch

path.logs: / var / log / elasticsearch

network.host: 192.168.72.10

discovery.seed_hosts: ["192.168.72.10", "192.168.72.4", "192.168.72.5", "192.168.72.20"]

cluster.initial_master_nodes: ["prso-elk-viten-1", "prso-home-1", "prso-elk-dm-1"]

Node: prso-elk-viten-1 (192.168.72.20)

cluster.name: PRSO_2021

node.name: prso-elk-viten-1

node.ingest: true

node.data: true

node.master: true

path.data: / var / lib / elasticsearch

path.logs: / var / log / elasticsearch

cluster.initial_master_nodes: ["prso-elk-viten-1", "prso-home-1", "prso-elk-dm-1"]

The node 192.168.72.5 I have not yet turned on

Errors - received:

Objective - reset the nodes to initialize a new cluster - clean and with new roles

Some advice before uninstalling elasticsearch - delete all files - reinstall elasticsearch ... let's see what happens.

Thank you very much
