Hi all,

First: I'm quite new to Torque and Maui. So forgive me if
this is a stupid question. But I didn't find a solution
in the mailing-lists yet.

I am running maui-3.2.6p16 and TORQUE 2.1.0p0.
My "Test-Cluster" consists of 1 node and I'm running
pbs_mom, pbs_server and maui on this node.
I allowed normal users to create reservations.


I want to set up a reservation and did the following
% setres -u martin -s +00:01:00 -d 0:10:00 TASKS==1


I can see the reservation :

-------------------------------------
% showres
Reservations

ReservationID       Type S       Start         End    Duration    N/P    
StartTime

martin.0            User -    00:01:18    00:11:18    00:10:00    1/1    
Sun Jun 11 17:57:18

1 reservation located
--------------------------------------

But when I try to submit a job to use the created reservation:
% qsub -W x=FLAGS:ADVRES:martin.0 testjob.cmd

the job stays queued even if the reservation becomes active.
(job-id: 109)


maui.log says the following:
...
06/11 18:00:08 INFO:     1 feasible tasks found for job 109:0 in

)

deferring)
06/11 18:00:08 WARNING:  cannot reserve priority job '109'
...

I don't understand the messages.
My current understanding is, that the job should start at the
start time of the reservation. Right?
Do I have to configure Advanced Reservations somewhere?
Any ideas?
Thanks in advance for any help!

Martin
