@saravanan30erd
Could you share inventory and playbook for multiple node setup ? Thanks

[saravanan30erd]

@patsevanton Actually I am using same configuration as it is.
https://github.com/opensearch-project/ansible-playbook/blob/main/inventories/opensearch/group_vars/all/all.yml

only change I am doing is, editing the host file for updating the nodes IP address details, thats all.
https://github.com/opensearch-project/ansible-playbook/blob/main/inventories/opensearch/hosts

It works fine, you can refer logs here

[patsevanton]

wait merge #51 for full test this issue

Hi @patsevanton that PR is merged now you can test again.
Thanks.

I tested again and again get this error

Inventory examples don`t have roles
https://github.com/opensearch-project/ansible-playbook/blob/main/inventories/opensearch/hosts_centos#L7
https://github.com/opensearch-project/ansible-playbook/blob/main/inventories/opensearch/hosts_ec2-user#L7

But opensearch-multi-node.yml have code:

node.roles: [{{ hostvars[inventory_hostname]['roles'] }}]

In this PR https://github.com/opensearch-project/ansible-playbook/pull/13/files

inventories/opensearch/hosts
without dashboard

quiestion:
Is dashboard0 requirenment roles or not?
