Backup of VMware Integrated Openstack

Hi,

We have created a NFS server using CentOS 7.3. We are able to share the NFS file system on a generic Ubuntu system but when we are trying to do the same on management of VMware Integrated OpenStack then we are facing issues, please see below. Can you please guide on this.

VIO version - 2.0.3, underlying layer consists of ESXi 6.0, vSAN, NSX, VIO is using NSX based networking.

When I run the command to take the backup,

The /mnt/backup folder is already present, see below

Thanks
