Hi,

If you want same cluster on multiple datacenter, you really need low 
latency (for proxmox && storage), and at least 3 datacenters to keep 
quorum.

if you need a 2dc datacenter, with 1 primary && 1 backup as disaster 
recovery

you could manually replicate a zfs or ceph storage to the backup dc 
(with snapshot export/import), or other storage replication feature if 
you have a san like netapp for example and do an rsync of /etc/pve.
