fifty2technology.openpbs

Description

This role is for installing and setting up OpenPBS on computer nodes, server nodes, or both. It follows the INSTALL instructions found in the official GitHub repository.

Note: If you change the configuration on a node that is currently running a simulation, OpenPBS will restart, which will also restart the simulation. To avoid issues, only run this on nodes that are not busy.

The Molecule scenario is tested in Podman with Rockylinux 9 and OpenPBS version 23.06.06.

Requirements

All nodes must be able to SSH into each other (this includes both OpenPBS servers and nodes) using the specified MPI user.
Inventory groups should be named pbsheadnode for the head node and mpinodes for the compute nodes. If using different group names, update the default variables openpbs_server_hostname, openpbs_server, openpbs_mom, and in templates/pbs.conf.j2.
Supported Linux distributions include Debian 11, Ubuntu 18.04, and Rockylinux 8/9.
Ensure working DNS name resolution, which includes FQDNs and non-FQDNs:
- Make sure your DNS servers resolve hostnames correctly.
- Check that /etc/resolv.conf has the correct search and domain entries.
- Hostnames should be in non-FQDN format (like foo instead of foo.example.org).
For RedHat-based distributions, make sure the PowerTools/CRB repository is enabled.

Role Variables

Variables that can be changed are stored in the defaults/main.yml file and in the table below.

Name	Default value	Description
`openpbs_version`	latest	Version of OpenPBS to install. It should be 'latest' or match a tag name in OpenPBS (e.g., `v20.0.1`). See the GitHub repository: https://github.com/openpbs/openpbs/tags
`openpbs_install_dir`	/opt/pbs	Directory where OpenPBS will be installed. This will also be added to your `$PATH`.
`openpbs_build_dir`	/opt/build_pbs	Directory for building OpenPBS.
`openpbs_server_hostname`	`"{{ groups['pbsheadnode'][0] }}"`	Hostname of the OpenPBS server (head node). Default is based on inventory group.
`openpbs_server`	`"{{ ( inventory_hostname in groups['pbsheadnode'] ) and not ( inventory_hostname in groups['mpinodes'] ) }}"`	Determines if a host is a PBS MOM or server based on group membership. Adjust group names as needed; logic should not be changed.
`openpbs_mom`	`"{{ ( inventory_hostname in groups['mpinodes'] ) and not ( inventory_hostname in groups['pbsheadnode'] ) }}"`	Determines if a host is a PBS MOM or server based on group membership. Adjust group names as needed; logic should not be changed.
`openpbs_dbuser_username`	pbsdata	User created for internal PBS use to access the database. Useful in case an update fails and you need to check the DB manually.
`openpbs_dbuser_password`	plzchangeme	Password for the above account.

Dependencies

None.
