[torqueusers] Cannot connect to specified server host

[Yousuke Itoh]

Dear all,


I am using a small cluster where CentOS 6.8 is running on the

job manager and CentOS 6.6 is running on each computing node.

All the nodes (the job manager and the computing nodes) run

torque version 4.2.10.


While everything worked fine last week,

I have got a following connection problem since yesterday


(Below Hongo-Login-v3 is the name of the job manager.)


***@Hongo-Login-v3 ~]$ qstat

Unable to communicate with Hongo-Login-v3(192.168.1.1)

Cannot connect to specified server host 'Hongo-Login-v3'.

Hongo-Login-v3


[***@Hongo-Login-v3 yousuke]# pbs-config --version

4.2.10


[***@Yushima-v3-01 ~]$ pbs-config --version

4.2.10


(Yushima-v3-01 is the name of the computing node 1)


This happens even after rebooting the whole cluster.


I really appreciate your help or any suggestions.


Best regards,
Yousuke

Check if the pbs_mom service daemon is running on the compute node (192.168.1.1),
or just restart it (service pbs_mom restart).
