NFS won't mount rw

NFS won't mount rw

[Chris Carlson]

We have a new problem that I was hoping someone could help with.

We have a Snap Appliance NFS server.  It has been recently upgraded, so 
it should have good NFS server software on it (though this isn't a 
guarantee).

We have a couple dozen Linux 2.4 systems that have it mounted (via 
automount).  No problem.  All mount is with root_squash and rw (not sure 
of the other options).

We just tried to "automount" it to a RedHat Linux Enterprise 5 system, 
and it mounted fine - except it is read-only.  Why would Linux 2.6 not 
mount it rw like the other systems?  Is it some security thing that we 
don't know?  Is there a bug in the NFS client on RH Linux?

If anybody knows what we're missing, I'd appreciate a clue.

Thanks a lot.
Chris Carlson

I don't suppose that this file system from the server is already
mounted somewhere on the client and is mounted there read-only?
The current RHEL-5 has a problem doing this.  It should be fixed
in the next release of RHEL-5.

    Thanx...
