[pve-devel] RFC V2 Storage Replica

[Alexandre DERUMIER]

also, target vmid can be different than source vmid.

so, I think when we initiate the first replication,
we generate a new vmid on target cluster,

then we store it in source vmid.conf

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.
