Hi,
For testing purpose of some functionnalities of postgres, we have restored a backup of an openvz (Proxmox 3.4) to an lxc (on Proxmox 5). On the original VM the disk usage of postgres is near 50gb, on the restored one it is 18gb. All data seems to there. We know that it could related more to postgres instead of Proxmox/OpenVZ/lxc but we don't understand how this is possible. Will some of you have an idea about this?
