We use XO from sources and after one update some versions ago, Remotes - NFS - Disk (Used / Total) shows nothing. Now we have version xo-server 5.57.3 / xo-web 5.57.1 on OS name: Debian GNU/Linux 9.12 (stretch) / OS kernel: 4.9.0-12-amd64 and xo-server 5.58.2 / xo-web 5.58.2 on OS name: Ubuntu 18.04.4 LTS / OS kernel: 4.15.0-96-generic and the problem appear on both VMs.
I am waiting for a solution from you. Thank you in advance!
