[PVE-User] ZFS Replication on different storage

I think it's hardcoded to use rpool as the default target pool, but I might be wrong.

You might want to have a look at pve-zsync instead ?

Thank you, I have already seen this page; i know and use zfs with freenas and other (tipically i use ceph, but for this cluster I only need the replication feature), but pve-zsync is used more for offsite-backup than redundancy, and the VM can't be migrated  from one host to another.
So, is not usable :(

Thanks, Fabrizio
