4.20.1 UI Dashboard Local storage total capacity is incorrect

### problem

**I have two KVM nodes, both using local storage:**

After adding multiple disks to the KVM node server, I repeatedly added and deleted local storage directories in the Primary Storage menu（The deletions resulted from poor directory layout planning）. Now, the UI Dashboard shows incorrect Storage Total values.

**However, I’ve verified that:**

The **Primary Storage Total** in the UI Dashboard is correct.
The **Local Storage Total** is incorrect.

How can I fix this discrepancy? can I manually correct the data in MySQL to resolve this issue?

### What to do about it?

_No response_

Comece reproduzindo a discrepância do Dashboard usando a configuração KVM descrita, depois de adicionar e excluir diretórios de armazenamento local, e compare Local Storage Total com Primary Storage Total. O relatório não menciona arquivos, testes ou pontos de entrada, portanto a investigação deve primeiro localizar o código que calcula e renderiza esses dois valores do Dashboard. Considera-se concluído quando Local Storage Total permanece preciso após as alterações de armazenamento descritas.
