    Hi, I've prox 4.1 (enterprise repo) and drbd9 cluster with thin provisioning enabled. I've seen that if I create a VM in drbd9 storage is correctly thin provisioned, but if I restore the VM then 100% (almost) of the space is alloccated.
    i.e. I've backedup VM 108 and restored as VM 999, and lvs shows this:
    root@prox01:~# lvs

      data  pve  -wi-ao---- 100.44g   
      root  pve  -wi-ao----  46.50g   
      swap  pve  -wi-ao----  23.25g
    Is it a bug or something I'm missing?
    Thanks in advance
