One CIFS Share with TWO File Systems

Is there any documentation or link you may have for nested file systems?

just copy that folder to a new file system and re-create the share.

take a look at nested file systems, it might help you accomplish what you are trying to do.

Sorry, I guess I should have mentioned that I need to keep the original share as there are other folders in there

I cannot just re-create the share as when I do this, it tells me the share name already exists, which is true because I need to keep the original share

Managing Celerra Volumes and File Systems Manually  6.0 A01

How about the manual?

Go to Powerlink and download the complete VNX file documention set

Is there a way to do this via the GUI and not via command line?

Also can I set this up with two existing file systems with data on them, or just with new file systems?

i have not set it up with file systems that had data, i am sure you can test it with a couple of test file systems.

I went through the manual, and was not too clear at all

Instead of using CLI, can I do it straight from Unisphere?

Yes – everything that can be done in UniSphere can be done via the CLI - see the manual

I recommend to go to Powerlink and download the complete VNX file documentation set

Probably

But it you dont understand it from the CLI and manual you wont understand it better from the GUI

1) No, you must use the CLI as there isn't an equivalent to create the filesystem (of -type nmfs).

2) Yes, you can mount existing filesystems (as well as newly created component filesystems) to the nmfs mountpoint 

The process simply involves unmounting the filesystems from their existing mount point and remounting to the nested mount root filesystem.  Data (and permissions) are inherent in the filesystem itself and are undisturbed in the process. 

You can refer to the above mentioned document: "Managing Volumes and File Systems on VNX Manually" available on Powerlink via the following breadcrumb trail:

Home > Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > VNX Series > Maintenance/Administration

Skip to the section: "Add an existing file system to an NMFS"

Went through the documentation and there is no mention around "nested file systems" or mounting of two file systems to a single CIFS share.

Does someone have the actual commands on how to do this?

It is definitely in one of the manuals - probably the AVM manual

As noted above, details are in either of the documents:

1) Managing Celerra Volumes and File Systems Manually

Home > Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > Celerra Network Server > Maintenance/Administration

2) Managing Volumes and File Systems on VNX Manually

Home > Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > VNX Series > Maintenance/Administration

Sections of interest would be:

a) Planning considerations: NMFS

b) Create an NMFS

c) Create a new component file system

d) Export an NMFS

e) Add an existing file system to an NMFS
