Snapshot Size Not Counted in Primary Storage Quota & Volumes Metrics Incorrect – ACS 4.20.0 (KVM + Ceph Reef)

### problem

**Issue 1:**
Volume snapshots for clients are configured to be stored in Primary Storage. However, in the account’s Primary Storage quota, snapshot sizes are not reflected — only the volume size is counted toward the Primary Storage usage.

**Issue 2:**
The Primary Storage is configured with thin provisioning, but in ACS the created volumes show the same values for *Volume Utilization* and *Physical Size* but the actual used size is not showing.

**Issue 3:**
For volume snapshots, only the *virtual size* is displayed; the *physical size* is not shown.

We are currently using KVM (Ubuntu) hypervisors with Ceph as the Primary Storage. Is there any additional configuration required to address these issues.

### versions

Apache CloudStack: 4.20.0

Primary Storage: Ceph Reef

Hypervisors: KVM (Ubuntu)

Comece reproduzindo os três comportamentos relatados no Apache CloudStack 4.20.0 com KVM no Ubuntu e Ceph Reef, comparando o uso da cota do armazenamento primário com as métricas de volumes e snapshots. Considera-se concluído quando for determinado se são necessárias alterações de configuração ou de implementação para que os tamanhos dos snapshots afetem o uso da cota e o uso físico seja exibido corretamente para volumes e snapshots.
