Issues with Linstor setup on proxmox cluster with VDO

Hi,

I have created a proxmox cluster and installed vdo on it along with linstor.

I am creating the linstor storage pool using below command

“linstor storage-pool create lvm proxnode1 pvevdo1 vgdo/vdolv” (Here vgdo is the volume group size 6.9 TB and vdolv is the logical voulume with 18TB storage).

So my linstor storage pool space should be of 18TB but i am getting the total space of 6.9TB and free capacity is of 1.8TB.

Please let me know where i am going wrong ?
