Hi @ all, I’m new on using OpenPBS. I finally want to install and run it on a small Cluster, but at present I’m trying to get it run on a single node and it fails everytime. I installed OpenPBS 20 (openpbs-master) following the guidelines in [https://github.com/openpbs/openpbs/blob/master/INSTALL](https://github.com/openpbs/openpbs/blob/master/INSTALL) . At present I got: dy@master:~$ sudo /etc/init.d/pbs status [sudo] Passwort für dy: pbs\_server is pid 10123 pbs\_mom is pid 2003 pbs\_sched is pid 2019 pbs\_comm is 1955 dy@master:~$ sudo /etc/init.d/pbs restart Restarting PBS Stopping PBS PBS mom - was pid: 2003 PBS sched - was pid: 2019 PBS comm - was pid: 1955 Waiting for shutdown to complete Starting PBS /opt/pbs/sbin/pbs\_comm ready (pid=10972), Proxy Name:master.local:17001, Threads:4 PBS comm PBS mom PBS sched PBS Server already running. dy@master:~$ ps -ef | grep pbs postgres 4536 1477 0 07:33 ?

But it is. I got the database pbs\_datastore including scheme pbs and tables. Running commands like qstat, qmgr fail, seams like hanging up. I got no response from the system. Firewall is disabled - generally disabled by default, but I checked it. SELinux is not found on the system. I figured out that it might be not installed by the OS at the beginning. According to this I assume this disabled. The OS I use is Linux Mint 19.2, which is equivalent to Ubuntu 18. The database is a postgresql 12. I checked the forum hoping to find someone experiencing the same problems and allready tried installation using data service user pbsdata as well, but it didn’t work. I also tried ./configure --with-database-dir / database-user which fails. I know sometimes I got the response “cannot connect to server (errorno=111)” or (errorno=113) when using a command. But that happens when some of the services are not running. Presently it seems that they are not communicating to each other and I don’t know why. I hope someone can help. Many thanks Sebastian ---

can you enable the postgres logs and check if anything in particular is logged. You can enable postgres client side logging to get better details. How did you install postgres? Check that the postgresql-contrib package is actually installed and the hstore module was installed as well (pbs uses this). you might also want to disable firewalls, flush iptables, and check that the postgres user is available and can be su’ed into. Another thing u could do is running the postinstall by hand, in debug mode, as follows: rm -rf /opt/pbs /var/spool/pbs make install sh -x /opt/pbs/libexec/pbs\_postinstall If you find pbs\_habitat failing inside this, you can add a sh -x to that script as well to see what is going on.
