[gpfsug-discuss] upgrading cluster with toolkit: precheck fails with "'scale_nfs_url' is undefined"

[Paul Musset]

Hello,

so the problem comes indeed from the fact I am not using CentOS or rhel

The list of rhel distribution supportedby the tool is in the 
`scale_rhel_distribution` list in 
`/usr/lpp/mmfs/5.1.9.2/ansible-toolkit/ansible/ibm-spectrum-scale-install-infra/roles/core_common/vars/main.yml` 
and 
`/usr/lpp/mmfs/5.1.9.2/ansible-toolkit/ansible/ibm-spectrum-scale-install-infra/roles/core_upgrade/vars/main.yml` 
or 
`/usr/lpp/mmfs/5.1.9.2/ansible-toolkit/ansible/ibm-spectrum-scale-install-infra/roles/core_install/vars/main.yml` 
depending if you upgradingare installing  your cluster

You first have to find under which name ansible recognise your OS with:
# ansible localhost -m'ansible.builtin.setup' | grep 
\"ansible_distribution\":
        "ansible_distribution": "Scientific",

Then you add it to the files described above.

scale_rhel_distribution:
  - RedHat
  - CentOS
  - Scientific

After that I managed to upgrade

I suppose it works also for other centos/rhel alternative like rocky and 
alma

Best
Paul
