yes, we already doing it for local disk live migration. (drive-mirror to nbd target)

I think we can simply define target storage in target proxmox cluster storage.cfg.


then on source cluster, define group of host(s) of target cluster + storage.
maybe add login/password  or some kind of special token (we could define it in target cluster)

something like:

remotesharedstorage: targetstoreid, host= targetnode1,targetnode2 , token=xxxxx    (like this we can have a retry to targetnode2 if targetnode1 is down)

remotelocalstorage1: targetstoreid1, host=targetnode1, token=xxxxx
      
remotelocalstorage2: targetstoreid2, host=targetnode2, token=xxxxx
      


and on source vm, define the target previously defined we want to replicate.

I do not talk about the technical implementation. I am 
just unsure how to store the configuration for the 
remote cluster/storage.
