I have a file system on NS80G Server_2 as R/w.i would like to mount the same file system as R/O on another datamover,server_3.If it is not possible,Can this be done by Virtual datamovers for NFS? Any thoughts?
similar - a virtual data mover is mostly a "container" for CIFS config plus the separation that a CIFS client conntection to C$ can only see/access the file systems that are mounted on that VDM and not the whole data mover.
so yes, you could mount a file system on the physical data mover (just once read-write) and then share it to multiple CIFS servers on different VDMs, but on the SAME physical data mover.
If that sepearation is enough then fine. For CIFS access you specify which interface is used per CIFS server.
But the interfaces are really owned by the physical data mover - so if your security people dont like having the different subnets on one physical data mover than VDMs dont help.
at least if I understood correctly what you want to achieve
