I want to move my contenaire LXC from Proxmox 5.3-7 (ext4) --> a new server Proxmox 5.3-11 in ZFS 2 x 450 GB NMVe.
(OVH server, install template Proxmox 5 ZFS)

  1. I backup a container from old server ext4
  2. scp to new server Proxmox FZS
  3. try to restore
FAILED !

I read that ZFS cannot have backup file ?
Strange ?

How can I transfert y LXC container from old ext4 server to new ZFS server ?

Thanks. Didier
 
Hello,

I have exactly the same problem that Didier on the same type of OVH server.

How can I "use ZFS as storage type"?

Do I have to configure something in ZFS Proxmox?

Or add something to the "pct restore" command?

Thanks!
