feat: slskd reconnect guard in downloaders_reset, mass v2 sync
- downloaders_reset: connection check block before slskd API sections; triggers PUT /api/v0/server reconnect if disconnected, polls 60s, gates Stuck Searches and Dead Transfer Records on SLSKD_CONNECTED - Sync all modified/new/deleted files from v2 refactor across Docker_Essentials, Media, Monitors, Partnership, Rsync, Tools, Transcodes, unRAID_Essentials, common.sh, master confs, and new Manual/README docs

# ================================= Server Reboot ==============================================
|
||||
# ==============================================================================================
|
||||
# Gracefully reboots the unRAID server with full pre-flight checks and clean shutdown sequence.
|
||||
# Warns all users, checks for active processes, stops services, syncs disks, then reboots.
|

#
|
||||
# ── SHUTDOWN SEQUENCE ─────────────────────────────────────────────────────────────────────────
|
||||
# 1. Pre-flight warnings — rsync, mover, active Emby sessions (warn not block)
|
||||
# PURPOSE
|
||||
# ─────────────────────────────────────────────────────────────────────────────
|
||||
# Gracefully reboots the unRAID server with pre-flight checks, user warnings,
|
||||
# clean service shutdown, and disk sync. Use instead of raw /sbin/reboot —
|
||||
# gives users warning time and ensures services stop cleanly before the kernel
|
||||
# drops.

||||

# ==============================================================================================
|

# OPERATIONAL MODEL
|
||||
# ==============================================================================================
|
||||
#
|
||||
# Shutdown Sequence
|
||||
# 1. Pre-flight warnings — rsync, mover, active Emby sessions (warn, not block)
|
||||
# 2. Wall message to all logged-in terminal users
|
||||
# 3. unRAID notification to dashboard
|
||||
# 4. Wait REBOOT_SLEEP seconds (default 30) — gives users time to save work
|
||||
# 5. Gracefully shutdown VMs (virsh shutdown each, then wait)
|
||||
# 3. unRAID dashboard notification
|
||||
# 4. Wait REBOOT_SLEEP seconds — users time to save work
|
||||
# 5. Graceful VM shutdown via virsh — ACPI signal, then wait REBOOT_VM_WAIT
|
||||
# 6. Stop libvirt (VM Manager)
|
||||
# 7. Stop Docker service
|
||||
# 8. Sync filesystem buffers to disk
|
||||
# 9. Reboot
|
||||
# 8. sync — filesystem buffers flushed to disk
|
||||
# 9. /sbin/reboot
|
||||
#
|
||||
# ── PRE-FLIGHT WARNINGS ───────────────────────────────────────────────────────────────────────
|
||||
# The following are warnings only — they do not block the reboot. You called this script,
|
||||
# so you know what you're doing. The warnings give you context before the countdown starts.
|
||||
# - rsync running → partial files possible if mid-transfer
|
||||
# - mover running → files may be left on cache or array mid-move
|
||||
# - Emby sessions → active streams/transcodes will be interrupted
|
||||
# Pre-flight Warnings (informational — do not block)
|
||||
# rsync running → partial files possible if mid-transfer
|
||||
# mover running → files may be left mid-move on cache or array
|
||||
# Emby sessions → active streams/transcodes interrupted
|
||||
# Warnings do not block the reboot — you called this script, you know.
|
||||
#
|
||||
# ── VM GRACEFUL SHUTDOWN ──────────────────────────────────────────────────────────────────────
|
||||
# virsh shutdown sends ACPI power button signal to each VM — same as pressing power button.
|
||||
# VM gets a chance to flush its own buffers and shutdown cleanly.
|
||||
# Waits REBOOT_VM_WAIT seconds (default 30) for VMs to shut down before stopping libvirt.
|
||||
# If VMs don't shut down in time libvirt stops anyway — system reboot takes priority.
|
||||
# VM Graceful Shutdown
|
||||
# virsh shutdown sends the ACPI power button signal — same as pressing the
|
||||
# physical power button. VM gets a chance to flush buffers and shut down.
|
||||
# After REBOOT_VM_WAIT seconds, libvirt stops anyway — reboot takes priority.
|
||||
#
|
||||
# ── HOST AWARENESS ────────────────────────────────────────────────────────────────────────────
|
||||
# detect_hosts() sets MY_ID — used in wall message, notification, and summary.
|
||||
# Critical on a two-server setup — wall and notifications show WHICH server is rebooting.
