Not able to add data node to a elasticsearch cluster

[Loudone]

Dear all,

I'm currently trying to make the following elasticsearch cluster:

My 3 master nodes are working fine, but my 3 others data nodes are not able to be connected to the masters:
error:

[2018-10-23T14:59:41,287][WARN ][o.e.d.z.ZenDiscovery ] [Data_Node_1] not enough master nodes discovered during pinging (found [[]], but needed [3]), pinging again

I trying to find a solution to have two node per vm, do you know how to do that?

Many tkanks for your help

below my actuals elasticsearch.yml configuration:

Hi,

In your data nodes configuration you need to add the port of unicast master hosts :

discovery.zen.ping.unicast.hosts: ["172.20.10.7:9300" , "172.20.10.6:9300" , "172.20.10.5:9300"]

bye,
Xavier
