Describe the issue:
Installing Standalone MCG with LSO requires at least three nodes and it explicitly means each node should include one disk and requires 3 disks (PVs). However, one PV remains eventually unused by default, so it's inconsistent with the number of node requirements. It's an expected behavior but not described in the document.

Describe the task you were trying to accomplish:
Above behavior should be documented in "Chapter 3. Deploy standalone Multicloud Object Gateway" to avoid confusion.

Suggestions for improvement:
