MOM Config incomplete

Users/Site Administrators
1

Hi All,

im a little stuck or i have confused myself completely now with a brand new issue from my previous ones!

So i have the pbs server running and all is well the config =
PBS.CONF output

PBS_SERVER=testserver.com
PBS_START_SERVER=1
PBS_START_SCHED=1
PBS_START_COMM=1
PBS_START_MOM=1 (edit: 0 to 1)
PBS_EXEC=/opt/pbs
PBS_HOME=/var/spool/pbs
PBS_CORE_LIMIT=56
PBS_SCP=/bin/scp

now i have the execution node setup and running (as in the service is green nothing more :unamused:) and heres my config for in in mom_priv

$clienthost server head
$restrict_user_maxsysid 999
$clienthost serverhead.test.com

And thats it is this correct as im getting no response when i run pbsnodes -a,
it tells me that the node is down.

netstat -n |grep 15003 gives me nothing some times a time_wait

i know im missing something simple but i just cant see the wood through the trees!

Cheers
Timbo

PBS_SERVER should be set to the hostname of your server. You have it set to ā€œserver headā€.

PBS_CORE_LIMIT should be set to the maximum allowed size for core files, or the string ā€œunlimitedā€ (without quotes). For example, PBS_CORE_LIMIT=536870912 sets the limit to 512MB.

$clienthost should be set to the hostname if the server. Again, you have specified ā€œserver headā€.

$restrict_user_maxsysid defaults to 999. It doesnā€™t harm anything to specify the default, but it isnā€™t necessary.

sorry the name server head really means testserver.com.

in the mom config the clienthost is that the execution node name or the servers name as i have the pbs_server=testserver.com in the pbs.conf already?

will change the core limit.

im just strugling to the the execution node to speak to the head server node (testserver.com).

4

Are there messages in the MoM log file indicating what the problem may be?

5

PBS_START_MOM=0 should be PBS_START_MOM=1 on the pbs.conf file.

6

sorry that is set to ā€œ1ā€ i must have miss typed it.

Sorry should have posted this earlier but its a task to remove stuff from a airgapped network.

Testserver.com is the head node the above log is from the testmom which is setup on a separate node for execution only.

9

could you please check if

  1. there is an entry for testserver.com in /etc/hosts file on the hosts.
  2. the firewall is blocking the communication.
10
  1. yes its in the hosts file
  2. firewall is off
11

I am just wondering why the ā€œcomā€ in testserver.com is capitalized in the mom logsā€¦

12

its been edited it should be lowcase
