I don't have a cluster wide ZFS storage. If I did, I would define a ZFS 
storage better, So that the cluster uses it, and that's all.
I have a mixture of 4 professional servers with hardware Raid 
controllers, and 4 not professional servers (PCs) with 4 hdds each one.
I want to create just one proxmox cluster with all these 8 servers.
In the 4 PCs, I had to install proxmox using the zfs Raidz1 advanced 
option, So that Proxmox to be installed  on a zfs Raid5.
Up to this stage,  I have redundancy, in such a way that I can remove 
any sata hdd and the proxmox can startup ok. And that's what I need ZFS.

So, on 4 nodes of the cluster I am able to use local-lvm to put CTs and 
VMs over there, but I am not able to put VMs and CTs on local-lvm in the 
others.
That's why I want to create pve VGs on the zfs nodes.
