🧰 Morpheus + Ansible Integration (Standalone Mode) for VM Provisioning (On-Prem & Cloud)

This guide walks you through setting up Morpheus 8 to provision virtual machines both on-prem (vSphere, KVM, Hyper-V) and in the cloud (AWS, Azure, etc.), and to automatically configure them using Ansible (Standalone mode) running from the Morpheus appliance.

The issue you're encountering is likely due to the use of the MBR (Master Boot Record) partitioning scheme. MBR has a partition size limitation of 2TB. If you have disks larger than 2TB and you want to use the entire space in a single partition, you should use the GPT (GUID Partition Table) partitioning scheme instead of MBR.

To use the full capacity of a 3TB (or larger) disk on RHEL6, you'd want to use the GPT format. Here's how you can create a GPT partition:

1. Backup any data: Before making any changes to the disk, ensure you've backed up any data on it.

2. Install gdisk: The gdisk utility is a version of fdisk for GPT. It might not be installed by default:
