[Help] Deploying new (MariaDB) database cluster. Stuck on Waiting for message logs. Job status defined.

Hello!

I am probably the noobiest sysadmin you will ever know, if I go wrong with something, feel free to tell me.

That said, I cannot seem to deploy a new database from ClusterControl. I am probably going with the import option now after manually configuring my cluster, but I want to know as much as possible what I am doing wrong with this, maybe I am missing some essential concepts. I have configured my cluster nodes with clean Ubuntu 16.04 LTS Server images, and root SSH access through pub key.

They are accessible from the shell of my Cluster Control host, and I can tell the new database cluster wizard also can do it, because when I add nodes to it, the SSH check is positive. But right when I click deploy and the job is started, it gets stuck on DEFINED status, with a message "Waiting for log messages ... " forever. I have to get inside the MySQL database and delete the job (is there any other way?). Logs are also empty.

I do not know how to debug this in a deeper level, can someone help me with this, please? :)

 EDIT. Finally had to go with a manual configuration and import. Still interested in what could have gone wrong with a from scratch deploy.
