Looks like PBS Pro is confused about the state of the datastore directory. Based on the previous thread, I am concerned that Torque is getting in the way. We may need to add Torque to the list of conflicting packages when PBS Pro is installed. Please try performing a clean install of PBS Pro by following these steps:

1. Read all of these steps before you start and understand what you are about to do before you proceed.
2. Stop any running PBS Pro services. (/etc/init.d/pbs stop)
3. Stop any running Torque services.
4. Make a backup of your system. At the very least, backup all Torque configuration files and components you may need to recover.
5. Uninstall PBS Pro. (e.g. for CentOS: yum erase pbspro-server)
6. Ensure PBS Pro is unsinstalled. (The following should be empty: rpm -qa | grep pbs)
7. Uninstall Torque and make sure it’s uninstalled.
8. CAUTION: Don’t delete any files or directories you haven’t backed up. Delete the following:

- /etc/pbs.conf
- /var/spool/pbs

1. Perform a fresh install of the PBS Pro RPM.
2. Start PBS Pro services.

I suspect it will successfully create the database and the PBS Pro services will start normally at this point. If you could capture your session in a typescript, that might help to identify problems if things continue to fail.
