CDF SOAR HA Deployment

HI, I am testing a CDF/SOAR deployment on a 4 VM infrastructure, where 3 VM will hold Master/Worker in each VM and 4th VM has the NFS mounted to it. 

The deployment is to simulate/test  Master/Worker node on a single VM/server deployment option to deploy SOAR only as capability along with fusion.

I am using attached yaml file configuration and when i run the pre-install check step using yaml file, it fails with error. 

It's an CentOS 8 install with all requiredO/S packages, arcsight user with GUID(1999), with ownership to install for install folders and NFS volume. 

has anyone tried this deployment method ? if yes then what should be the yaml configuration and what other things to be relooked to avoid any obvious errors.
