[Users] exception occured when adding NFS storage

[Zhang, Hongyi]

Hi Itamar,

No any trace was logged in the file /var/log/vdsm/vdsm.log during the creation of the storage on the ovirt.engine side. But the vdsm is running:

# systemctl status vdsmd.service
vdsmd.service - Virtual Desktop Server Manager
   Loaded: loaded (/usr/lib/systemd/system/vdsmd.service; enabled)
