It is possible to lock down VNX NFS shares behind individual VLANs so that the client "showmount" command cannot display all the remote hosts (VNX’s) NFS mounts for the attached X-Blade.  Using the "server_export" command with the "-options" switch, the nominated NFS share is hidden behind the assigned VLAN.  When used with the "access" switch, it is possible to hide the NFS mount behind a particular VLAN and limit access to the server/client PC via IP address, NetGroups, Host Name or /etc/passwd entry.    The command examples:   $ server_export server_2 –Protocol nfs –option vlan=407 access=192.168.42.100 /mnt_AAAA server_2 : done   $ server_export server_2 –Protocol nfs –option vlan=518 access=192.168.42.120:192.168.42.121 /mnt_BBB server_2 : done
If using a VNX File NFS solution, how do I stop different servers and/or clients seeing the various NFS exports?
How to stop NFS exports being seen by different servers/clients?
