Mounting NFS Shares from Windows Storage Server on another Linux Server
Hello forum.

I've got a brand spanking new NAS running Windows Storage Server 2003 with a newly exported NFS share. The NFS share is on a 3.2 TB GPT disk with an NFTS partition. I've exported the NFS share and have successfully mounted the NFS share onto two servers running RHEL4. The event log on the NAS shows two successful mounts.

However, when I try to access the newly mounted NFS share, I get the following:

bash: cd: /remitpro/imageshare/: Input/output error
There are no errors in the event logs on the NAS to indicate anything specific. I will say that the Storage Server Management interface on the NAS has a way to map UNIX NIS accounts to Windows or AD accounts, but I haven't set any of those because I'm not looking for authentication, just auditable access to this device.

If anyone out there has any experience with mounting NFS shares from WSS2003, I'd really appreciate your help.

Thanks in advance...

I thought I checked the "anonymous access" checkbox when creating the NFS Share on the NAS, but evidently didn't. I'm now getting "Permission Denied". I'll post my findings, but if anyone has anything to say about the new error, I'd appreciate hearing it.

The user mapping settings were the issue. I copied the passwd file from one of my client machines to the server, and in the Windows Storage Server Management snap-in for MMC.

I right-clicked on User Name Mapping, and browsed to and added the passwd file under "Password file path and name:" and closed the window. Then I right-clicked on "User Maps", clicked the "List UNIX Users" and the "List Windows Users" buttons, highlighted "root" and "administrator" and clicked add. Once that was done, I restarted the NFS server on the NAS and was able to list and create files in the NFS share from the client.

The files created all had root:root for ownership.

I should add one more note. I felt a little iffy about associating the root user to the administrator user, so I created a normal unprivileged user and gave it read/write access to the folder being shared by NFS, then re-created the user mapping for root to the new user.
