Hello,

I realize this may be off-topic for this mailing-list, but at this point I am not sure where the problem is continue troubleshooting. We have a server that has Windows Unified Data Storage Server that is supposed the be able to provide NFS shares. I have attempted to setup a NFS share and I think I have it setup correctly on the server. I have the User Mappings created on the Windows server and share setup.

When I mount the share from my CentOS server, I get this:

# mount -o rw storage:/share /srv/nfs # ls -l total 1 drwx------ 2 4294967294 4294967294 64 Dec 11 14:46 nfs # ls -l nfs ls: nfs: Permission denied

My guess would be permissions on the Windows server, but the test it, I have setup "Everyone" to have full control of the share while I test it. If anyone has experience with SFU and would be will to give me some pointers that would be great.

You will need to setup the "Administrator" or "root" permissions separately on the SFU server.

Otherwise test it with some other user account on the CentOS box.

"Everyone" permissions has no application to NFS shares.

This is more of a Windows issue than CentOS, so feel free to contact me off-list.

Sorry to ask the obvious, but are you sure you are configuring the share via the "NFS Sharing" tab and not the "Sharing" tab in the Properties dialog? They are completely different animals. You don't specify user permissions for NFS shares other than which hosts have access and whether or not the root user has access.

If your share is set up right, then I would suspect that your implementation of User Name Mapping may be incorrect. I'm using Storage Server 2003 which should be more or less the same as your Windows box, so I should be able to offer additional assistance with Mapping if that is the issue.

We access Windows NFS from CentOS all day, every day, so I know it can be done. Once you are up and running, I would be interested in your observations on performance. We have occasional problems with concurrency. While one process is rsync-ing a bunch of small files to NFS, another machine accessing a different NFS share will get "permission denied" and the Windows Event log will show "A User Name Mapping error has occurred" with no helpful details. Still scratching our heads on that one.
