Bom dia a todos, utilizo um Proxmox 5.3.5 com um disco de 2TB e nele tenho duas VMS conforme print abaixo em anexo:

Estou enfrentando problemas com local-lvm que seria minha Poll LVM-Thin chegando a 100% e uma das VMS não consegue iniciar.

Alguém saberia me informar como faço para fazer uma limpeza e ganhar espaço, não entendo o porque esta sem espaço as duas vms estão praticamente vazias.

Abaixo segue informações das LVMS do proxmox:

Também enfrento uns problemas por causa disso.
Já reparei que quando volto um backup, algumas VMs voltam com a opção "write zero=1", que faz com que tudo o espaço de disco seja pré-alocado, e outras vem com "write zero=0", ocupando muito pouco espaço. Mas nunca entendi qual é o critério que ele usa pra decidir isso, poderia ter uma opção onde o usuário escolhesse isso.
De qualquer forma, tente clicar no disco virtual da VM e escolher Editar, depois marque a opção Descartar, isso libera um pouco de espaço, mas não muito.

Bom dia amigo, obrigado por compartilhar sua experiência, não entendi onde vc diz para selecionar o disco virtual e editar, ao selecionar o disco virtual em Local-lvm não aparece a opção de editar, utilizo a versão Virtual Environment 5.3-5

Tem um camarada que me disse o seguinte veja se isso pra você faz sentido :

"Olá amigo, pelo visto o proxmox não está conseguindo fazer leitura de área dos volumes no storage, tente fazer algum reyscan dos volumes no servidor proxmox"

Você sabe como faz esse reyscan e se pode ser realizado a quente ?
