nfs mount permission issues
Hello,
We have some new application requirements that require us to use nfs mounts from aix 5.3 and mount to Oracle Linux 5.6.

Do you know why when on the destination ( linux ) box, the root user cannot access directories made by other users in the nfs mounted filesystem ?

I read that there needs to be an option in the /etc/exports file for the source, called -maproot=root.
I tried that, but am not sure of a clean way to have the client read the exports file again to take the new parameter.

Any ideas would be appreciated.

Thanks,
floyd

Never mind, I figured it out.
If i put the option "root=client" in the exportfs file, it works.

mount.nfs

MOUNT.NFS(8)						      System Manager's Manual						      MOUNT.NFS(8)

NAME

       mount.nfs, mount.nfs4 - mount a Network File System

SYNOPSIS

       mount.nfs remotetarget dir [-rvVwfnsh ] [-o options]

DESCRIPTION

       mount.nfs is a part of nfs(5) utilities package, which provides NFS client functionality.

       mount.nfs  is  meant to be used by the mount(8) command for mounting NFS shares. This subcommand, however, can also be used as a standalone
       command with limited functionality.

       mount.nfs4 is used for mounting NFSv4 file system, while mount.nfs is used to mount NFS file systems versions 3 or 2.   remotetarget  is  a
       server share usually in the form of servername:/path/to/share.  dir is the directory on which the file system is to be mounted.

OPTIONS

       -r     Mount file system readonly.

       -v     Be verbose.

       -V     Print version.

       -w     Mount file system read-write.

       -f     Fake mount. Don't actually call the mount system call.

       -n     Do not update /etc/mtab.	By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip making
	      an entry.

       -s     Tolerate sloppy mount options rather than fail.

       -h     Print help message.

       nfsoptions
	      Refer to nfs(5) or mount(8) manual pages.

NOTE

       For further information please refer nfs(5) and mount(8) manual pages.

FILES

       /etc/fstab	 file system table

       /etc/mtab	 table of mounted file systems
