Hola a todos, Hace unos pocos años que estoy trabajando con esta solución ELK y no consigo reiniciar todos los nodos de un cluster para… empezar de cero con un nuevo cluster 1º - Eliminar todos los datos almacenados Si que consigo eliminar índices … (desde línea de comandos) **curl -X DELETE "nodo:puerto/indice\_name"** por ejemplo un borrado completo curl -X DELETE "192.168.0.210:9200/\*" 2º - Configurar un nuevo cluster - limpio **Mi nuevo cluster** **Nodo: 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"] **Nodo: 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"] **Nodo: 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"] El nodo 192.168.72.5 todavía no lo he encendido Errores – recibidos: Nodo prso-home-1 [2021-02-10T07:47:43,900][WARN][o.e.c.c.Coordinator] [prso-home-1] failed to validate incoming join request from node [{prso-elk-viten-1}{ZPUhwBeiRM65AllVbmAnPA}{deSn9qdBRO-MxBuwWIOqNA}{192.168.72.20}{192.168.72.20:9300}{cdhilmrstw}{ml.machine\_memory=8589934592, ml.max\_open\_jobs=20, xpack.installed=true, transform.node=true}] org.elasticsearch.transport.RemoteTransportException: [prso-elk-viten-1][192.168.72.20:9300][internal:cluster/coordination/join/validate] Nodo prso-elk-viten-1 Caused by: org.elasticsearch.transport.RemoteTransportException: [prso-elk-viten-1][192.168.72.20:9300][internal:cluster/coordination/join/validate] Caused by: org.elasticsearch.cluster.coordination.CoordinationStateRejectedException: join validation on cluster state with a different cluster uuid 1epEQFGfRgqPhi7Z1qfQ1Q than local cluster uuid nx6DeRiiTXS1zwX3gf6BvQ, rejecting Nodo prso-elk-dm-1 [2021-02-10T00:40:59,182][INFO][o.e.c.s.ClusterApplierService] [prso-elk-dm-1] master node changed {previous [{prso-home-1}{X-qTdaIoSuKqud-1AIayZQ}{BKUNpp47SaW82wXMMgmgyw}{192.168.72.4}{192.168.72.4:9300}{cdhilmrstw}{ml.machine\_memory=7516192768, ml.max\_open\_jobs=20, xpack.installed=true, transform.node=true}], current }, term: 475, version: 191, reason: becoming candidate: onLeaderFailure Objetivo – resetear los nodos para inicializar un nuevo cluster – limpio y con nuevos roles Algún consejo antes de desinstalar elasticsearch – eliminar todos los ficheros – reinstalar elasticsearch… a ver que pasa. Muchas gracias Pablo ---

Hola Pablo, En principio todos los datos del cluster están en `path.data: /var/lib/elasticsearch`. Si quieres empezar de cero, borrar el contenido de `path.data` te debería permitir reiniciar un nuevo cluster, con los roles de nodos actualizados. Al no encontrar datos (cluster state y datos/indices), el cluster se formará de nuevo. Aunque no es imprescindible borrar los datos para cambiar roles, entiendo que esto es lo que quieres por el mensaje. Un saludo! ---

```auto Hola Imma, Un poco radical - pero 100% efectivo - exactamente buscaba eso - gracias ;) ``` ---
