Hi all.
I've used NFS in the past but only for file sharing, but now I need to use
it in a live environment for uses email/web etc across load balanced
servers.
The problem I have is that the maildirs have to be owned by the user they
belong to as does the web content.
However when I mount an NFS share on both servers it's mounted as root with
full permissions.
The problem is every file/directory created in the mounted NFS share is also
created owned by root, even when I try to change the permission to a
different owner or try to chmod a file or directory it doesn't do anything.
Is there a way of being able to use NFS in the way I want?
I'm running this on Centos 4.3 servers with nfs-utils-1.0.6-65.EL4.
Thanks
Tony

What NFS version are you using 2, 3 or 4?

Setting the 'no_root_squash' export option on the server might help...

This confuses me... You mean a "share from server 1 _and_ server 2"
right?

No... this does not make any senses...

In general, the user and group should exist on both the server
and client; but the user and group ids do not have to explicitly
exist on the server...

Yes... On the server export the filesystem with the 'no_root_squash'
option which will allow root on the client to change ownerships with
the chown command.

Ok it was me doing something wrong as I just tried it again and it worked.
Sorry.....
What's the best line to put into /etc/fstab to mount the share?
Currently I have:
192.168.1.1:/data /home nfs rsize=8192,wsize=8192,timeo=14,intr 0 0
Thanks
Tony
