We have a single-node Proxmox setup with one VM, which is a Proxmox Backup Server.

The node has a total storage capacity of 20 TB, of which 14 TB is allocated to the VM. Currently, the VM has used 6 TB of storage, leaving about 8 TB available within the VM. However, Proxmox VE is showing a total usage of 18.93 TB out of 20 TB. the disk configured with btrfs

I’m not sure where the remaining storage has gone. Does anyone have any insights?
