# Proxmox cluster Keepalived deployment

# - Discovers cluster members with `pvecm nodes`
# - Uses the first non-VIP IPv4 address on the selected interface as each
# node's Keepalived unicast source address
# - Derives VRRP priority from the hostname's trailing numeric suffix
# priority = PRIORITY_BASE - trailing_number
# so pve1 > pve2 > pve3 when PRIORITY_BASE=200
# - Deploys a Proxmox-aware health check including cluster quorum
# - Uses nopreempt so the VIP does not fail back after a recovered node returns
# - Starts the highest-priority node first so initial ownership is deterministic
#
# Run this from any healthy, quorate Proxmox cluster node as root.
