As I said, I didn't replicate it with proxmox or proxmox code currently. only custom scripts calling ceph api directly. I need to dig a little bit more in current proxmox zfs replication, because it' mainly focus on local storage replication. so it's a little it different with a shared storage (vm live migration, ha failover,...) ----- Mail original ----- De: "Mark Adams" <m...@openvs.co.uk> À: "proxmoxve" <pve-user@pve.proxmox.com> Envoyé: Jeudi 17 Mai 2018 17:36:43 Objet: Re: [PVE-User] pve-csync version of pve-zsync?
