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

network.host: 192.168.72.20

discovery.seed\_hosts: ["192.168.72.20", "192.168.72.4", "192.168.72.5", "192.168.72.10"]

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:

**Prso-home-1 node**

**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

Pablo
