NFS export & Windows Server

which protocol do you want to use in the Windows server - CIFS or NFS ?

I want to use NFS protocol in windows server 2003.

nothing special on the Celerra side

just install and configure NFS on Windows and create a Celerra NFS export as normal

As Rainer mentioned earlier - on the Celerra side, you need to create the NFS export on the physical data mover - select the proper path on the desired file system on the Celerra side while creating the NFS export.

Also, you may consider putting the name or IP Address of the NFS client (your Windows server running NFS) on the Read-Write, Root and Access hosts fields - these fields are self explanatory - if needed you may take the help from "Online Help Pages".

From where the other guys left off, once you've configured the NFS export on Celerra, for Windows you can download an NFS client.

There are loads of NFS clients (some graphical ones) available, and alot of them are free to download.

Hello I've configured NFS export on celerra and installed  client services for Unix on windows server 2003. windows host  can only read but can't write  in nfs mount.windows host  has  read-write access in the NFS export configuration setting .Any ideas what I'm missing ?

Thanks .

Add the host name to the "Root Hosts" field on the NFS export page on the NAS.

Thanks,

there is no authentication in NFS

its probably a question which UID/GID your NFS client for Windows picks

create a directory with rwx access for ugo from a real NFS client or the control station

then write a file from your Windows client there and take a look with ls which UID/GID it uses

this has nothing to do with user mapping on the Celerra - since your are using a NFS client the UID/GID is determined by the client

another potential problem could be if the Celerra for some reason cannot reolve the hostname in the export - try an IP address instead

Hello ,

I added the windows server host name to "Root Hosts" and "read/write" but I got the same result.  Do i need to configure user authentication for NFS access  on celerra?

Thanks.

I can reach NFS export but  can't write it. I use client services for windows on   host.

i checked the gid and uid ;

GID: -2

UID : -2

thanks .

Hi,

most likely your root= export on the Celerra is wrong - i.e. a name that cant be resolved or the wrong IP address

what happens is if that your NFS client apparently uses root UID 0

a NFS server by default maps that to UID 65534 (nobody in Unix world) which happens to be -2 in 16bit world

this is a security feature since in Unix root id god and isnt restricted by permissions - so a NFS server needs to be careful whom to give full unrestricted access

for troubleshooting - just use anon=0 on the Celerra NFS export

if that works then find a permanent solution, like fixing the root= clause or setting up usermapping on your Windows client so that you dont use UID 0
