Thin provisioning
Allocating physical space only for blocks that are actually used
Core Idea
Thin provisioning is Allocating physical space only for blocks that are actually used, regardless of the virtual disk size assigned to each VM. Thin pools share capacity, and when data or metadata usage reaches 100% writes will fail and VMs freeze. It usually makes the most sense alongside Storage pool, Proxmox Backup Server (PBS), Recovery dry run.
Why It Matters Here
Mathbong reuses this term across proxmox posts as shared vocabulary.
