I have an online backup server which mounts through nfs several file
systems from my production servers and uses rsysc to copy the files over
locally.  It works GREAT!  I can backup the changes of a 30 gig drive in
under 10 minutes every night!
Now, I've gotten some extra servers that I'm going to add as hot standby's
and use the same setup to sync the data every 15 minutes (I don't have
enough servers to do true clustering *yet*).

Here is the problem, for some reason, I can not get root read-able!  I've
even stripped down the permission thinking I had a conflict between the two
servers and nothing.

online backup server 172.16.1.103.
standby server 172.16.1.15
server  being backed up 172.16.1.13

In the /etc/dfs/dfstab file I have

share -F nfs -o rw,root=172.16.1.15 /export/home

on my online backup server I
mount accrc13:/export/home /mnt

If I change the 15 to 103 (the old ip address of my online backup server),
reshare that partition and for the old server it works fine.  I'm unmounted
the file system and remounted it when I make changes.  I've checked the
/etc/hosts.allow and while I can mount the partition, unless it is world
readable, I get a permission denied.  I created a user on the standby
server with the same uid and gid of one of my users and I can then read and
write to the file system without a problem :-/  I've checked my dns and
removed checking nis from /etc/nsswitch.conf just in case even though it
was last......

This simple task has been driving me NUTS for 2 days!  What am I over
looking!?!?

Thanks,
Stephen
