Nate:
Yes that helps a bunch! I verified that
pbs_server was in fact connected to port 15000 on cree. I restarted using
pbs_mom –S 15000 on huron and everything works fine now.
Thanks again. Now I can do some real work
J
Cheers,
Tim

contact with server at hostaddr problem (followup)
Tim,
I have
managed to mis-configure pbs to give me these symptoms in two ways:
1)
pbs_server isn't running on the port that the mom thinks it is. Make sure
that the pbs_server is running on 15001 (looks like you're already looking at
this). As mentioned not long ago, you can start the mom with pbs_mom -S
15000 to force mom to look for the server at port 15000. (though I
suppose a wise thing to do may be to see what port pbs_server is running on
first).
2)
Fudged up ethernet names for the server on the mom (personally, I've done this
with multi-homed servers). Does the mom-node (cree?) know who
huron(server) is (and vice versa)? Is that an entry in /etc/hosts on the
mom-node? Being a wimp, I almost always use the ip of the server in the
config file for the pbsserver entry to avoid making this mistake.
I
suppose the third option is that pbs_server is actually running at all on
huron.
Hope
that helps,
Nate

Garrick:
Sorry I wasn't clear
My set up is
Node1 (cree): running pbs_server, pbs_mom
and maui
server_priv/nodes:
cree np=8
Huron np=8
mom_priv/config:
$pbsserver cree
Node2 (huron): running pbs_mom only
mom_priv/config:
$pbsserver cree
When I submit the following on cree
echo "sleep 30" | qsub
the job appears to be scheduled on huron and runs
OK but then I start
seeing the "No contact with server at
hostaddr port 15001" error
messages repeated in the mom_logs file on huron
and it appears that the
pbs_server never is notified that the job ran to
completion.
Hope this clears things up a little.
Regards,
Tim

It is a little hard to figure out your setup here
with "client",
"server", and "remote" nodes.
If both hosts are to handle compute jobs, then you
want pbs_mom running
on both hosts and both hostnames in
server_priv/nodes.
