NFS - move FS from physical DM to VDM

Hi,

Currently i have an environment with NFS Exports on Physical Data Mover mounted FS and i need to move all the File Systems to a VDM.

Current File Software Version : 7.1.65-8

1. Can it be done via GUI?

2. If it has to be done only thru CLI, what is the command ?

3. I read some document and understood the NFS export path need to be modified?  can you also explain how the path need to be modified  thru CLI?

Thanks

Dino

There is no builtin move for this.

You just need to

- (Unless you have already done so) attach an interface to the VDM and check its config

- Unmount the fs from the DM – don’t forget the perm flag

- Mount fs on the VDM

- Create the NFS exports based on the VDM

- Remove the DM based export

See the NFS and VDM manuals for more details

The mount/umount’s you can do via the GUI – the VDM NFS export and config is CLI only

If you are doing this while in production test with a test file system first so that you have the order and config correct - otherwise you risk running into stale NFS file handles.

IF you have applications running from these NFS export you need to work out a procedure to keep the interface down while the NFS file handles aren’t valid.

Thanks Rainer_EMC

This is what i tried on a test FS name : testdin12

1) Unexported the NFS export of a FS mounted on physical datamover "server_2"

server_export server_2 -unexport perm pathname /testdin12


2) Unmounted FS on server_2


server_umount server_2 -perm /testdin12


3) Deleted the pathname


server_mountpoint server_2  -delete /testdin12



After that i created a vdm and named "test-vdm1" and i mounted the File System on that vdm and path name /testdin12


and now  NFS export of the file system was created using the below command


server_export test-vdm1 -o root=10.X.X.X,access=10.X.X.X,rw=10.X..X.X /testdin12


Issue : Not able to mount the FS on the server with path name /testdin12 , which is the mount point.



Need your guidance.



Thanks

Sounds like, you did not follow Rainers advice:

  • -          "(Unless you have already done so) attach an interface to the VDM and check its config"


The command for this is:

nas_server  -vdm -attach

I think step 1 should have been

- Read the relevant sections of the VDM manual and the NFS manual to understand the feature

Dynamox,

yes i added the protocol,

server_export test-vdm1  -Protocol nfs -o root=10.X.X.X,access=10.X.X.X,rw=10.X..X.X /testdin12



sorry i missed it while typing.

can you post output from "server_df test-vdm1"   ..did you also try to attach the interface as recommended above ?

[nasadmin@CHE-INF-FILE01-CS0 ~]$ server_df test-vdm1

test-vdm1 :

Filesystem kbytes used avail capacity Mounted on
testdin 20651504 2776 20648728 0% /testdin
testdin12 10325744 2760 10322984 0% /testdin12

I haven't attached an interface, i will create a new virtual interface and attache it to the vdm.

Did this work. You need to specify root-vdm path to mount
