These is not possible because I don't use zfs on the eight nodes ? Just 
in 4 of them and modifying /etc/pve/storage.cfg is a cluster wide operation!
More over. I use zfs under the Proxmox (In the S.O level) to join the 
internal disks. So that proxmox node NEVER sees any zfs, just the local 
storage (Dir /var/lib/vz) that is mounted on the internal zpool 
(rpool/ROOT/pve-1) that is the zfs pool (The 4 disks together seen as one).

Now the problem is that I have 4 nodes with local-lvm storage active and 
4 nodes with just local storage active, because in these  last nodes the 
local-lvm is disabled! (Due to the non-existence of any lmv volumen group)

So, the migrations of MVs between all these nodes cause problems.
