[Moabusers] data staging

[Brock Palen]

We are having some problems with setting up data staging on moab with  
torque-2.1.2

In trying to run /opt/moab/tools/system.query.dstage.pl   The  
following function is missing:

Undefined subroutine &main::readSpool called at ./ 
system.query.dstage.pl line 48

The Moab::Tools  PM does not include that sub and i can not find it  
declared any other place.

I try to submit the job like so:

brockp at nyx ~]$ qsub -I -l nodes=1 -q svti -W stagein=/home/brockp/ 
file.dat at ragnar.engin.umich.edu:/home/brockp/file.dat

and moab is configured with

RMCFG[nyx]      TYPE=PBS HOST=nyx.engin.umich.edu DATARM=storage
RMCFG[nyx]      SBINDIR=/usr/local/torque/sbin

DATASTAGEMODEL EXTERNAL
RMCFG[storage] TYPE=NATIVE RESOURCETYPE=STORAGE HOST=nyx.engin.umich.edu
RMCFG[storage] SYSTEMQUERYURL=exec:///opt/moab/tools/ 
system.query.dstage.pl
RMCFG[stoarge] CLUSTERQUERYURL=exec:///opt/moab/tools/ 
cluster.query.dstage.pl
RMCFG[storage]      SBINDIR=/usr/local/torque/sbin

I get the following:

qsub: PBS: MOAB_INFO:  interactive job can never run - data stage for  
RM 'storage' not possible - it has no nodelist (check CLUSTERQUERYURL)

I think this might be resolved by the location of the sub's   
writeSpool and readSpool
Some notes:  The host providing the data (ragnar.engin)  has ssh keys  
set such that the cluster nodes can scp files from that machine to  
them selfs without a password.  BUT if i dont configure moab at all  
and just tell torque to data stage i get the message in the torque  
email of:

PBS Job Id: 39374.nyx.engin.umich.edu
Job Name:   STDIN
File stage in failed, see below.
Job will be retried later, please investigate and correct problem.


Unable to copy file brockp at ragnar.engin.umich.edu:/home/brockp/ 
file.dat to /home/brockp/file.dat

>>> error from copy
>>>
Host key verification failed.

>>> end error output


This is odd because i can go as my user and ssh to ragnar from the  
nodes and scp from the nodes files off ragnar.
