NFS Mount option

[blal]

Hello ,

I have an application using NFS share (From EMC NAS)

Using nfs mount the file NFS file System (from NAS) is mounted on a unix and a windows server.

Windows server is wrting the files , and the application running on unix can not read and execute these files . All the files are appearing with unknown user ID and Group id on unix server . I believe this is the root cause .

Is there any specific mount option which I can use so that the Application running on unix can read and execute these files .

Appriciate your help .
Thank You,
Baiju.

Baiju,

This will need to be configured at the NAS end. Ask your NAS administration about the Windows User/group mapping. He/She can map the Window user to a specific user/group, such that your UNIX user has read/execute permissions.

Shalom,

No special mount options I know of. In general these issues came from users/permissions problems on the files.

If a common user name, preferably with the same numeric user id is used these problems can be overcome.

You could also use samba/cifs integration, this requires a common user and not using NFS. Most of these NAS devices support Samba/CIFS mounts. Our EMC does.

You need a mechanism to handle common UID's and GID's. Some Windows NFS packages are able to use NIS; I haven't seen one that is able to use NIS+. Almost all NFS clients have some form of Windows Users to UNIX user mapping and that is what you need to investigate.

You could also write a daemon to periodically fix up the uid's, gid's, and modes of the file but user mapping is a better option.
