[PVE 6] Add proxmox storage.
Here is how to add harddisk into proxmox storage pool.
1. After we connect new hard disk to our host. Verify attached harddisk in proxmox.
2. Format each harddisk. We will add sdb – sdf to our new storage pool.

5. Add the ZFS pool to proxmox. Go to Datacenter -> Storage -> add -> ZFS
Choose ZFS pool we created at step.3 then add
Verify our news storage is enabled and active. 🙂
