Whoops! data directory /var/lib/postgresql/14/main is already initialized

[vitabaks]

the server you are trying to add to the cluster already contains PGDATA

[vitabaks]

if it's not production data, you can just clean up the /var/lib/postgresql/14/main directory before adding the server to the cluster.

[vitabaks]

In addition to deploying new clusters, this playbook also support the deployment of cluster over already existing and running PostgreSQL. You can convert your basic PostgreSQL installation to a high availability cluster. Just specify the variable postgresql_exists='true' in the inventory file.

If one node could not be repaired, how can you get rid of ansible

[vitabaks]

I don't understand your question :)

[Muhtarhan27]

If one node could not be repaired, how can it be removed from the cluster
