# ==============================================================================================
|
|
#
|
|
# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Monitors ramdisk usage and manages the transcode symlink direction. Called by
|
|
# transcode_management.sh (Orchestrators/) every 3 minutes — always after
|
|
# transcode_cleanup.sh runs first. Must be fast, non-blocking, and silent when
|
|
# nothing has changed.
|
|
#
|
|
# Emby's transcode path points at TRANSCODE_LINK (a symlink). ffmpeg resolves
|
|
# the symlink once at session start and holds a direct reference — existing
|
|
# sessions are completely unaffected by symlink flips. Only new sessions care
|
|
# where the symlink currently points.
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL MODEL
|
|
# ==============================================================================================
|
|
#
|
|
# Three Modes (TRANSCODE_MANAGER_MODE)
|
|
# smart — auto-flips between ramdisk and SSD based on usage thresholds (default)
|
|
# ramdisk above RAMDISK_WARN_GB → flip to SSD
|
|
# ramdisk below RAMDISK_LOW_GB → flip back to ramdisk
|
|
# ramdisk — always uses ramdisk, warns if above threshold, never flips
|
|
# ssd — always uses SSD, never uses ramdisk (use during drain or maintenance)
|
|
#
|
|
# Safety Checks — Every Run Regardless of Mode
|
|
# Symlink missing/broken → recreate pointing at ramdisk, notify
|
|
# Ramdisk disappeared → flip to SSD immediately, notify warning
|
|
# SSD path missing → disable SSD fallback (error if mode=ssd)
|
|
# transcoding-temp missing → recreate on ramdisk silently
|
|
# Permissions drift → fix silently every run
|
|
# Emby not running → skip threshold checks, verify symlink only
|
|
#
|
|
# Session Display
|
|
# Shows active streams from all configured TRANSCODE_SERVERS with user, title,
|
|
# type (Live TV / TV Show / Movie), and play method (Transcode / Direct).
|
|
# Split state shown when sessions exist on both ramdisk and SSD — normal during
|
|
# a flip while ramdisk sessions drain.
|
|
#
|
|
# Daily Log
|
|
# Appends one entry per run to TRANSCODE_DAILY_LOG, read by weekly_health_digest.sh.
|
|
# Format: DATE|RAMDISK_USED_GB|FLIP_COUNT|RAM_SESSION_COUNT|SSD_SESSION_COUNT|FILES_CLEANED

|
|
# OPERATIONAL SAFEGUARDS
|
|
# ==============================================================================================
|
|
#
|
|
# Wait Lock
|
|
# acquire_lock "wait" — waits if the previous run is still active. The 3-minute
|
|
# interval can overlap on a system under heavy load.
|
|
#
|
|
# Docker Timeout
|
|
# DOCKER_TIMEOUT caps all docker calls against a hung daemon.
|
|
#
|
|
# Notification Validated
|
|
# validate_unraid_cmd confirms the notify script is present before use.
|
|
#
|
|
# Silent by Default
|
|
# Runs every 3 minutes — only speaks when something changes or needs attention.
