Hello,

I have a Proxmox VE setup with zfs pool storage. If i open the storage Summary in the GUI i get wrong total size:

1685453327781.png

Proxmox reports 730278658048 bytes but zpool, lsblk and parted report 754275319808 bytes.
Why?
 
Hi,
not all of the physical space can be used for data by the ZFS filesystem. There is an overhead because of filesystem structure, internal metadata, etc. The command used by Proxmox VE is zfs list -p -o available,used ValidateApps.
