Issue getting 2.73TB partition LVM to have free space

Good Morning,

Probably a stupid question, but I've never had this problem with fdisk on smaller partitions.

I used parted to make a 3TB partition into a LVM for my proxmox 2.0

However, when I add it as an LVM into proxmox, it says 2.73Tib used out of 2.73 Tib.

I've tried a hundred times, same result. I can mount it as a directory, then the space is free, but as an LVM its full.

Any ideas much appreciated.
