Headers claimed protections the code never had, and several destructive paths had no guard against a collapsed config value.

# ================================= Array Start Orchestrator ===================================
|
|
# ==============================================================================================
|
|
#
|
|
# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Single entry point for array start — fired by the Varaverk plugin's
|
|
# disks_mounted event hook (Plugin/unraid/event/disks_mounted/array_start_jobs).
|
|
# Launches everything configured in ARRAY_START_SCRIPTS in master.conf.
|
|
# This script exits after launching all scripts — the event hook sees it complete normally.
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL MODEL
|
|
# ==============================================================================================
|
|
#
|
|
# Configured in master.conf ARRAY_START_SCRIPTS — no changes to this script ever needed.
|
|
# Current order (order matters — see below):
|
|
#
|
|
# ONE-SHOT (run and exit naturally):
|
|
# System_Essentials/unraid_api_key_renew.sh — re-register Varaverk API key at boot
|
|
# System_Essentials/inotify_tuning.sh — raise inotify limits before containers start
|
|
# System_Essentials/docker_syslog_filter.sh — suppress veth log noise before logs fill
|
|
# System_Essentials/php_fpm_max_children.sh — WebGUI performance tuning
|
|
# Transcodes/ramdisk_setup.sh — create tmpfs + symlink before Emby starts
|
|
# Docker_Essentials/docker_network_connect.sh — ensure networks + container connections
|
|
#
|
|
# CONTINUOUS (run until array stops):
|
|
# Fallback/fallback.sh — mutual fallback monitor
|
|
#
|
|
# NOTE: watchdogs (docker, system, stability) are NOT launched here.
|
|
# They run via watchdog_orchestrator.sh every 15 min (cron), not as daemons.
|
|
#
|
|
# Script is launched in background with bash script.sh &
|
|
# After 1 second: if PID still alive → continuous (running in background)
|
|
# if PID dead + exit 0 → one-shot completed successfully
|
|
# if PID dead + exit N → failure
|
|
#
|
|
# ==============================================================================================
|
|
# DESIGN PRINCIPLES
|
|
# ==============================================================================================
|
|
#
|
|
# Order Is Load-Bearing
|
|
# inotify limits must be raised before containers start — containers that
|
|
# start with low limits keep them. Ramdisk must exist before Emby starts.
|
|
# Docker networks must be connected before watchdogs check container states.
|
|
# fallback.sh goes last — it needs everything else stable to make decisions.
|
|
#
|
|
# Configuration Owns the List
|
|
# ARRAY_START_SCRIPTS in master.conf is the only place scripts are added or
|
|
# removed. This orchestrator never needs to be edited to change what runs —
|
|
# one-shot vs continuous behaviour is auto-detected from the PID after launch.
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL SAFEGUARDS
|
|
# ==============================================================================================
|
|
#
|
|
# Root Enforcement
|
|
# Every script launched here requires root.
|
|
#
|
|
# Lock Acquisition
|
|
# acquire_lock prevents duplicate array start launches. Unraid can fire the array
|
|
# start hook more than once, and a second pass would re-launch continuous scripts
|
|
# that are already running.
|
|
#
|
|
# Host Detection
|
|
# detect_hosts() sets MY_ID for notifications.
|
|
#
|
|
# Empty Job List Guard
|
|
# Exits with an error and a notification if ARRAY_START_SCRIPTS is empty. An empty
|
|
# list would silently bring the array up with no ramdisk, no network setup, no
|
|
# watchdogs and no fallback — while reporting a clean start.
|
|
#
|
|
# Executable Auto-Fix
|
|
# Non-executable scripts are chmod +x'd before launch. A permission bit lost to a
|
|
# git checkout or a file copy should not silently disable a boot-time component.
|
|
#
|
|
# Full Path on Failure
|
|
# Failures report the exact resolved path, so a missing script is immediately
|
|
# distinguishable from a script that ran and failed.
|
|
#
|
|
# Failure Notification
|
|
# Any script that fails to launch raises a notification — array start is unattended,
|
|
# so a silent failure here would only surface much later as a missing service.

|
