Note the "duplicate" packages, from the EPEL and the OpenHPC (preferred).
This could lead to installation of the wrong version (note it comes from epel)
# dnf install slurm-slurmrestd

we will look into disabling the epel repo during the slurm install. success rate depends a bit on how other dependencies are resolved.
it seems that all ohpc packages for slurm trails with -ohpc, which makes it easier to distinguish. as such we have to revise the slurm role to just use the ohpc packages, instead of a mix currently. Then disabling the repo is not needed.
Earlier comment confirmed. slurm_packages_ohpc only contains packages with the trailing -ohpc. The role only installs slurm from epel if openhpc is disabled:
- name: Install slurm packages
yum:
name: '{{ slurm_packages }}'
state: present
tags: install-only
when: enable_openhpc == false
- name: ensure legacy slurm rpms are not installed before configuring ohpc versions
yum:
name: '{{ slurm_packages }}'
state: removed
tags: install-only
when: enable_openhpc == true
....
- name: Install ohpc slurm packages
yum:
name: '{{ slurm_packages_ohpc }}'
state: present
tags: install-only
when: enable_openhpc == true
There is no risk installing wrong packages during TrinityX installation.
typical package set after installing on the controller:
- slurm-ohpc-22.05.8-300.ohpc.4.6.x86_64
- slurm-perlapi-ohpc-22.05.8-300.ohpc.4.6.x86_64

i close the ticket.
