Pbsnodes: cannot connect to server , error=111 and Failed to start PBS dataservice

Hi Team,
I am using pbspro ce 19.1.1 on rocks cluster with Master and Compute-0-0.
Still yrsterday it was working fine. today when i check the pbsnodes -aSj it is getting below error.

[root@master ~]# pbsnodes -aSj
Connection refused
pbsnodes: cannot connect to server master.calligotech.com, error=111

then i check the pbs status

[root@master ~]# service pbs status
pbs_server is pid 5189
pbs_mom is pid 2362
pbs_sched is pid 2374
pbs_comm is 2333
[root@master ~]# service pbs restart

[root@master ~]#

the reason is because of database not shutdown properly. please help me out to resolve this issue.

Regards,
Zain

The PBS_SERVER assigned hostname/FQDN is the problem here. Please use the correct resolvable short hostname (alias) and make sure there are no duplicates.

Please check the PBS server logs when you run the command pbsnodes -aSj to find out through which IP/hostname the commands are reaching the pbs server , also you can check with strace pbsnodes -aSj

Please check the below section of the PBS Professional Installation and Upgrade guide


Hi,
Whenever we start the master node , pbs service is automatically running and after sometime it is getting error as below.

[root@master ~]# pbsnodes -aSj
Connection refused
pbsnodes: cannot connect to server master.calligotech.com, error=111

What is the reason some times it will work properly and sometimes not. please help me out.

The PBS_SERVER hostname mentioned in the /etc/pbs.conf should be resolvable ( reverse/forward ) from the PBS Server and Compute Nodes.

Please run this command on the PBS Server host:
pbs_hostn -v master.calligotech.com

Please run this command from the compute node hosts:
pbs_hostn -v master.calligotech.com

For this error:
source /etc/pbs.conf
cd $PBS_HOME/datastore
edit pg_hba.conf and find this line
host all all 0.0.0.0/0 md5

and update it to
host all all 0.0.0.0/0 trust
and restart pbs services and check ps -ef | grep pbs_

Otherwise please try:
update your /etc/hosts on the PBS Server host , to :
10.1.50.1 master.local master
#192.168.0.50 master.calligotech.com master

and /etc/pbs.conf
PBS_SERVER=master
and remove
PBS_SERVER_HOST_NAME

Hi,

Actually we have rebooted server, after that we tested pbsnodes -aSj it worked fine.
