My problem ended up being a misconfigured interface
(servera-nfs....does not have routing information). I
did received very personal support, esp. from "system
administration account" <sysadmin_at_astro.su.se> whom
we exchanged several emails, great thanks, and also
thanks to Paul Madelaine and Trevor Osatchuk. They all
took this problem as their own. The replies that help
me figure out the problem are listed below:
We have had a similar issue in the past. We
have found the
problem to lay in the name you are using in the
exports file. If a
system
name contains a "-" the exportfs command parses this
as a delimiter.
With
the standard usage of a line in export to be something
like this:
/u3/dir5 -root=milan -anon=-1
You can see where hostnames with "-" in them
can screw them
up.
If you are using host tables, you can try an
alias. Add this
line
to your /etc/hosts file:
xxx.xxx.xxx.xxx seavera-nfs.company.com servera-nfs
serveranfs
And then change your /etc/exports to look
something like this:
/dir -root=serveranfs,access=serveranfs
Hope this helps a little.

What I did was use the nfs nic for nfs share only.(and
big ftp's and
the
like) From my rc.configs:
NETDEV_0="ee0"
NETDEV_1="ee1"
Then in hosts, both machines:
192.168.1.10 mustang #regular nic ee0
192.168.2.10 mu #nfs nic with abbreviated host name
ee1
192.168.1.11 pinto #regular nic ee0
192.168.2.11 pi #nfs nic with abbreviated host name
ee1
I did this on pinto in /etc/exports:
/usr -root=0 mustang
/mnt -root=0 mustang mu #I can export to both nics
So from mustang:
mount pi:/mnt /mnt
Works just fine! Hope this helps.

Interesting. You realize, I hope, that using different
names and IP
addresses only gives you control over which interface
is used for
*inbound* traffic. In other words, you can tell
clients to mount
filesystems from serverA-nfs; but in the opposite
direction it's
a lot harder to split the traffic across interfaces in
the way you
describe.
If serverB similarly had two IP addresses (call one
serverB-nfs), then
you could tell serverA to mount from serverB-nfs, and
add a route to
serverB-nfs through the FDDI interface. But if serverB
only has one IP,
you can't use the route table to send some traffic
through one
interface
and some through the other.
If you could easily modify the NFS client code on
server A, you might
arrange to bind() specifically to the -nfs IP rather
than to 0.0.0.0.
But you might then just as well run Linux or one of
the free BSDs...

Because the route from server A to serverB goes
through the
wrong interface.
