# tasks file for linstor_cluster
# IMPORTANT: All Linstor node registrations use ansible_hostname (the real system hostname)
# to ensure they match Proxmox node names, which are also derived from the system hostname.
# The Ansible inventory_hostname (e.g. "pve1") may differ from the real hostname (e.g. "pve-node-01").
