# Apply peer-connections plan: deploy cleaned node lists, restart RPC 2101, optionally 2102/2201.
# See: docs/08-monitoring/PEER_CONNECTIONS_PLAN.md
#
# Usage: ./scripts/maintenance/apply-peer-plan-fixes.sh [--deploy-only] [--restart-2101-only]
#   --deploy-only       Only deploy node lists (no restarts).
#   --restart-2101-only Only restart VMID 2101 (assumes lists already deployed).
# Requires: SSH to Proxmox hosts (r630-01, r630-02, ml110). Run from LAN.
