Hello, we recently created a cluster on 2 VMs , 1 with Elasticsearch as MASTER node and another with Elasticsearch as DATA node . How do i allocate the replicas ? it seems the primary is allocated but the replicas arent. We had a single node set up till last week and today we tried our hand with the cluster setup ```auto curl 172.26.207.168:9200/_cat/nodes?v ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 172.26.207.168 29 99 90 32.40 24.52 17.36 d - Nexus_elasticsearch_dev02 172.26.207.164 57 92 2 0.40 0.25 0.14 m * Nexus_elasticsearch_dev01 ``` ```auto req_lines 0 p STARTED 4436417 827.3mb 172.26.207.168 Nexus_elasticsearch_dev02 req_lines 0 r UNASSIGNED c_lines 0 p STARTED 1621071 248.8mb 172.26.207.168 Nexus_elasticsearch_dev02 c_lines 0 r UNASSIGNED gmon_lines 0 p STARTED 57000 22.8mb 172.26.207.168 Nexus_elasticsearch_dev02 gmon_lines 0 r UNASSIGNED dnsp_lines 0 p STARTED 6902280 345.1mb 172.26.207.168 Nexus_elasticsearch_dev02 dnsp_lines 0 r UNASSIGNED f_lines 0 p STARTED 922366 203.4mb 172.26.207.168 Nexus_elasticsearch_dev02 f_lines 0 r UNASSIGNED .kibana_task_manager_7.15.0_001 0 p STARTED 15 1.4mb 172.26.207.168 Nexus_elasticsearch_dev02 .apm-custom-link 0 p UNASSIGNED .kibana_7.15.0_001 0 p STARTED 132 4.8mb 172.26.207.168 Nexus_elasticsearch_dev02 .apm-agent-configuration 0 p UNASSIGNED .kibana-event-log-7.15.0-000001 0 p STARTED 1 6kb 172.26.207.168 Nexus_elasticsearch_dev02 .ds-ilm-history-5-2021.12.01-000001 0 p UNASSIGNED ``` ---

and the output of GET /\_cluster/health , incase if it helps to fix this ```auto { "cluster_name" : "ELK-nexus", "status" : "red", "timed_out" : false, "number_of_nodes" : 2, "number_of_data_nodes" : 1, "active_primary_shards" : 8, "active_shards" : 8, "relocating_shards" : 0, "initializing_shards" : 0, "unassigned_shards" : 8, "delayed_unassigned_shards" : 0, "number_of_pending_tasks" : 0, "number_of_in_flight_fetch" : 0, "task_max_waiting_in_queue_millis" : 0, "active_shards_percent_as_number" : 50.0 } ``` ---

You can not as the dedicated master node can not hold data. If you change it into a master/data node the replicas should get assigned assuming you have enough space. ---

thanks for the response @Christian_Dahlqvist . Could you tell me if having a master node is a requirement in a cluster set up ? you said "If you change it into a master/data node the replicas should get assigned assuming you have enough space." - can a node have multiple roles i.e to be both a master and data node ? ---

For small clusters having dedicated master nodes is usually not required. If you are startring out I would start with 1 or 3 nodes that have all roles. ---
