QCOW2 disks on LVM do not report size for powered-off VMs.

[RovshanP]

Hello All,

For powered-off VMs, we cannot view or query the size of QCOW2 disks on LVM storage — unless the VMs are powered on or activated via SSH.
Is this a bug?

Hi,
yes, this is a technical limitation, because the size needs to be queried from the qcow2 file that resides on top of the logical volume. But if the logical volume is not active, that cannot be done. The size of the logical volume itself would only be an approximation. Still, feel free to open a feature request to improve this: https://bugzilla.proxmox.com/

You should be able to get this info outside the GUI:
