Pbs_server is not running

nekcorp · March 17, 2019, 3:25pm

Hi,

/etc/init.d/pbs status return :

pbs_server is not running
pbs_mom is not running
pbs_sched is not running
pbs_comm is not running

I have stopped and restarted server with /etc/init.d/pbs stop | start command but I have the same message. When I submit a job it is stay queued.

Can you please tell me what is the problem ?

Thank a lot for your help

Can you please post the output that you see when you run “/etc/init.d/pbs start” ?

If the job status is queued then server service is up and running.

Please share the output of

qstat -fx
pbsnodes -av
qstat -answ1

If you cannot run these commands, then share the server and scheduler logs.

Thank you for sharing the logs.

make sure ports 15001 to 15007 , 17001 are not blocked and SELinux disabled & system is rebooted after disabling SELinux.
make sure the /etc/hosts is populated correctly ( DNS is properly configured for forward and reverse address resolution) on the headnode and across all the compute nodes

03/18/2019 08:56:45;0002;Server@centos7-1;Svr;Server@centos7-1;PBS dataservice not running:[Connection: failed: could not connect to server: Connection refused
Is the server running on host “192.168.1.49” and accepting
TCP/IP connections on port 15007?]
FYI: https://blog.bigbinary.com/2016/01/23/configure-postgresql-to-allow-remote-connection.html

if you check the scheduler logs, you see there are messages regarding system ulimits. Increase the ulimits at the system level or you can populate the system limits in /opt/pbs/lib/init.d/limits.pbs_mom & /opt/pbs/lib/init.d/limits.pbs_server .
Check the server logs ( scheduler is down, server is contacting the scheduler here)

Thanks a lot for your help

Hello,

I see that this is an old post, wondering if anybody can help. I installed openPBS and very strangely when I run " sudo /etc/init.d/pbs start " its says:

Starting PBS
PBS comm already running.
PBS scheduler already running.
PBS Server already running.

but when I do “/etc/init.d/pbs status” it shows:

pbs_server is not running
pbs_sched is not running
pbs_comm is not running

I am confused. I run few jobs, they remain in queued and error file shows:

/var/spool/pbs/mom_priv/jobs/2001.PiMaster.SC: line 28: /home/pi/demo/fpi-serial: Permission denied

and output file is:

SSH is enabled and the default password for the ‘pi’ user has not been changed.
This is a security risk - please login as the ‘pi’ user and type ‘passwd’ to set a new password.

Thanks for helping
Best

I also encountered the problem of “Max files allowed = 1024, Max files too low - you may want to increase it”
All of the following operations are performed by root

My steps are as follows:
(1)The default ulimit -n of my OS is 1024.
So when the PBS service is started, PBS_mom, pbs_sched,pbs_serveres all prompt as follows (no pbs_comm):

			01/07/2022 18:01:16;0d80;pbs_mom;TPP;pbs_mom(Main Thread);Max files allowed = 1024
			01/07/2022 18:01:16;0c06;pbs_mom;TPP;pbs_mom(Main Thread);Max files too low - you may want to increase it.
			01/07/2022 18:01:36;0d80;pbs_sched;TPP;pbs_sched(Main Thread);Max files allowed = 1024
			01/07/2022 18:01:36;0c06;pbs_sched;TPP;pbs_sched(Main Thread);Max files too low - you may want to increase it.
			01/07/2022 18:02:02;0d80;Server@cf-poc-master;TPP;Server@cf-poc-master(Main Thread);Max files allowed = 1024
			01/07/2022 18:02:02;0c06;Server@cf-poc-master;TPP;Server@cf-poc-master(Main Thread);Max files too low - you may want to increase it.

(2)Then I change ulimit -n 102400 in /etc/security/limits.conf:
root soft nofile 102400
root hard nofile 102400

(3)Then restart the machine and confirm that the modification takes effect
command “ulimit -n” output 102400

But, when PBS service starts again, pbs_mom, pbs_sched and pbs_server(except pbs_comm) still report warning mean that 1024 too low like above,
then I try command “ulimit -n 102400” in the current login shell, it still no effect

Why?

Should I modify ulimit in the pbs’s systemd service conf file,or by systemctl, or there maybe some conf in pbs overwrite the OS config?

Looking forward to your reply, thank you!

PS：
[root@cf-poc-master ~]# cat /opt/pbs/lib/init.d/limits.pbs_mom
if [ -f /etc/sgi-release -o -f /etc/sgi-compute-node-release ] ; then
MEMLOCKLIM=ulimit -l
NOFILESLIM=ulimit -n
STACKLIM=ulimit -s
ulimit -l unlimited
ulimit -n 16384
ulimit -s unlimited

The contents of this fils limits.pbs_mom should be on the below line (remove the conditional if)

MEMLOCKLIM= ulimit -l
NOFILESLIM= ulimit -n
STACKLIM= ulimit -s
ulimit -l unlimited
ulimit -n 16384
ulimit -s unlimited

and restart the pbs services on the compute node.
Similarly, you can have the limits.pbs_sched and limits.pbs_server in the same location with the same contents and restart respective services.

Make sure /etc/security/limits.conf has the following entries:
( restart the system or sysctl -p should work )

soft memlock unlimited
hard memlock unlimited

Hope this helps
