General Issues

⦾ Why are cluster nodes getting incorrect hostname (nid) after OIM reboot?

Potential Cause: If OIM is rebooted after clusters are deployed, cloud-init files are no longer retained on the OIM. When compute nodes are PXE booted afterwards, they cannot access the cloud-init configuration on OIM. This results in default hostnames like nid00... instead of the configured hostnames from the PXE mapping file.

Resolution: Run the provision.yml playbook again with the same PXE mapping file. This ensures cloud-init files are properly recreated and compute nodes receive their correct configured hostnames from the PXE mapping file.
