SUMMARY: NFS problems

The problem was due to a duplex mismatch between the two machines.
Both alphas (AS1000A) have DE500 NICs. One is set to 100Mpbs full
duplex, with autonegotiating off, the other had autonegotiating on, but
didn't.

I set the card to full-duplex, fast mode at the SRM prompt:
>>> set ewa_mode fastfd
and also had to append 'speed 200' to the IFCONFIG_0 line in
/etc/rc.config

Thanks to Sean O'Connell for providing all the answers.

Original question:

 Hello all,

I'm experiencing problems with NFS. Our mail server was getting rather
full. To create more space I had to put part of the folder areas (not
the spool area) onto another server. although it seems to work, I keep
on getting erro messages on the client console like this:

Mar 20 10:39:15 basil vmunix: NFS2 server tarragon not responding still
trying
Mar 20 10:39:15 basil vmunix: NFS2 server tarragon ok
Mar 20 10:39:15 basil vmunix: NFS2 server tarragon not responding still
trying
Mar 20 10:39:15 basil vmunix: NFS2 server tarragon ok
Mar 20 10:39:15 basil vmunix: NFS2 server tarragon not responding still
trying
Mar 20 10:39:15 basil vmunix: NFS2 server tarragon ok
Mar 20 10:39:16 basil vmunix: NFS2 server tarragon not responding still
trying
Mar 20 10:39:16 basil vmunix: NFS2 server tarragon ok
Mar 20 10:39:16 basil vmunix: NFS2 server tarragon not responding still
trying
Mar 20 10:39:16 basil vmunix: NFS2 server tarragon ok

The link is made in fstab with:

/usr/users/staff_at_tarragon /usr/users/staff nfs
rw,bg,timeo=10,retrans=30 0 0

 and is exported with

/usr/users/staff -rw=basil -root=basil basil

I've tried al sorts of permutations with timeo, retrans, etc. on the
client, as well as changing the
number of tcp/udp daemons on the server, but to no avail.

Any suggestions as to what I might be doing wrong are most welcome.

Thanks,
