Hi
Currently I am using HP NAS box and we have installed “HP Storage Works storage Mirroring” on NAS for Replication. Windows 2008 is installed on this NAS box. I have shared a directory as NFS share on this NAS box and allow anonymous read and write access to all machines. I want to mount and access this NFS share directory on one LINUX machine and this Linux machine has Redhat 5.3 Enterprise edition.

1. The issue I am facing here is, I can mount the NFS share on my Linux machine successfully but I can not do read/write on this NFS share. Whenever I try to access this mounted NFS share, I always get error “Permission denied”. I can’t do any read/write operation on this mount point. Please provide the inputs to resolve this issue.
2. How do I mount NFS share with user credential and password? Can I share a directory as NFS share with user credential which I can use when I mount the share?
3. Is there any other way to access NFS share by using user authentication and password?

Regards
Chirag

Not familiar with the NAS box... in general, you have to have matching userids, possibly even uids across the NAS and the clients... it depends. In general writes are disallowed for root as that would mean that any old root could kill anything, anywhere (just build your own box... attach... and destroy). Have you tried writing as any user? (not root)

With that said, the root_squash thing usually doesn't affect reads... so I'd suspect something is not quite right on the "anonymous" HP NAS setup... might simply mean the anonymous user (which can vary).

Do you know what NFS version level the NAS is supporting? My guess is that it support up to v3 and prefers v3 (that's what most do). NFSv4 adds more variables... but I'd think it unlikely in most NAS's.

The NFS server on Windows 2008 (NAS box) supports both NFS version 2 and 3. the NFS server is on windows 2008. What additional things required if NFS server is on windows machine so I can access NFS share from Linux?

Not sure. Just the thought of NFS under Windows makes me cringe. I wouldn't trust it long term.

I wonder if SFU's (or whatever it's called now) NIS like thing is required to make things work well.. at least with regards to username mappings??

Do you HAVE to run the NFS off of Windows?

What works:

Linux holding the file share exposed via NFS and Samba.

What doesn't work:

Using Windows for file sharing in a heterogeneous network.

Just my opinion...
