I have two vms and one is pbstest1 which has pbs pro server installed, the other one is pbsproexecutionserver1 which has pbs pro execution installed. But execution host couldn’t talk to pbs pro server.
- PBS pro server status:
[root@pbstest1 server_logs]# systemctl status pbs

- Check pbs_mom process in pbs pro execution host:
[root@pbsproexecutionserver1 sbin]# ps -ef|grep pbs_mom
root 10268 1 0 05:38 ? 00:00:00 /opt/pbs/sbin/pbs_mom
root 10328 9430 0 05:54 pts/0 00:00:00 grep --color=auto pbs_mom
- also we can use passwordless ssh between pbs pro server and pbs pro execution using user root.
Could you please help check what’s wrong with the configuration? Thanks a lot.
