Dear Support,
I am in the process of installing a LCG2.6.0 CE_torque and WN_torque on a
cluster machine running Rocks 3.3.0 (Makalu).
The native torque is 1.0.1p6-1 and is packed in a different way (single rpm
containing everything: pbs and mom server, and mom and other clients (cli and
gui) and was working fine.
I first installed the LCG2.6.0 "manually" (using diverses solution pure rpm,
yum, apt). Run the yaim configure (for dteam VO). Queue system was created
properly and I could submit globus jobs to the
lcg queue (dteam). I added manually with qmgr a "non-default" default queue
which worked fine.
Now I wanted to use the yaim install and the meta rpms for nodes that contain
nothing else than dependencies. I had to remove the native torque and get
installed the 1.0.1p6-11.SL30X.st version which is packed in several rpms.
On CE_torque:
torque-1.0.1p6-11.SL30X.st
torque-resmom-1.0.1p6-11.SL30X.st
torque-server-1.0.1p6-11.SL30X.st
torque-clients-1.0.1p6-11.SL30X.st
torque-devel-1.0.1p6-11.SL30X.st
lcg-CE_torque-2.6.0-sl3
on WN_torque:
torque-clients-1.0.1p6-11.SL30X.st
torque-1.0.1p6-11.SL30X.st
lcg-WN_torque-2.6.0-sl3
torque-resmom-1.0.1p6-11.SL30X.st
I noticed that configuration files are not in the same place (/opt/torque/ for
native torque vs /var/spool/pbs/ for sl30x) and rerun yaim configuration for
both CE and WN and restarted maui, pbs_server, pbs_mom on CE and pbs_mom on WN.
That's where I get into trouble! It seems that jobs get queued but for some
reason never execute. They stay in the 'Q' state forever.
% qsub -q default test-pbs.sh
1037.grid.bccs.uib.no
% qstat -a
grid.bccs.uib.no:
Req'd Req'd

Job ID Username Queue Jobname SessID NDS TSK Memory Time S Time
--------------- -------- -------- ---------- ------ --- --- ------ ----- - -----
1037.grid.bccs. patrickg default test-pbs.s -- -- -- -- 48:00 Q --
The same happen if I submit a globus job
% globus-job-run grid.bccs.uib.no:2119/jobmanager-lcgpbs -queue dteam
/bin/hostname
% qstat -a
grid.bccs.uib.no:

--------------- -------- -------- ---------- ------ --- --- ------ ----- - -----
1038.grid.bccs. dteam001 dteam STDIN -- 1 -- -- 48:00 Q --
Running pbsnodes, I get such output
compute-0-0.local
state = state-unknown,down
np = 2
properties = lcgpro
ntype = cluster
Looking at the pbs_mom log (in /var/spool/pbs/mom_logs), it seems it is first
reading the config file from the WM (/var/spool/pbs/mom_priv/config)
$clienthost grid.bccs.uib.no
$clienthost grid.local
$clienthost localhost
$clienthost localhost.localdomain

and then many lines with the same message:
pbs_mom;Svr;pbs_mom;im_eof, End of File from addr 129.177.120.153:15001
In the pbs_server log (in /var/spool/pbs/server_logs), there are lines:
Type disconnect request received from [log in to unmask], sock=9
Type statusqueue request received from [log in to unmask], sock=9
Type statusjob request received from [log in to unmask], sock=9
On the working node pbs_mom log there are many lines (about every three
minutes)
Premature end of message from addr 129.177.120.153:15001
The maui run is 3.2.6p11-2_SL30X
% rpm -qa|grep maui
maui-server-3.2.6p11-2_SL30X
maui-3.2.6p11-2_SL30X
maui-client-3.2.6p11-2_SL30X
and I can see in /var/log/maui.log on CE there are lines like
INFO: PBS node compute-0-0.local set to state Down (state-unknown,down)
INFO: 0 PBS resources detected on RM base
WARNING: no resources detected
There seems to a problem of communication between CE and WN.
Does the torque expect communication through something different than ssh/scp?
The Rocks torque works with ssh and rshd is disabled.
Could it be the problem?
Also there seems to be some problem with packaging
% rpm -qa | grep ^torque | xargs rpm -qV

even though
% rpm -qf /var/spool/pbs/server_priv/acl_svr

Do you any idea what is going wrong?
I found at Steve Staylen's site (http://hepunx.rl.ac.uk/~traylens) newer
versions of torque rpms for sl3 (2.0.0p1-2.sl3.st) than the one provided by
CERN but still with same packaging.
Are these test rpms? Can they be used for LCG production? Do you think it
will solve my problem?
Any help is appreciated
Sincerely,
Patrick
