Codebase-wide audit pass: fixed real bugs (SSH hangs missing BatchMode, local-outside-function no-ops, variable name collisions, a truncated ratio calc, wrong state-dir path, DARK vs NO_INTERNET drift, and more), then pulled logic that was duplicated across multiple scripts — arr cleanup safety gates, docker restart ordering, container maintenance stop/restart, watchdog state-file helpers, partnership role resolution, cert expiry checks, remote node discovery, and TMDB discovery scoring — into common.sh so each now has a single implementation.

# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Creates missing Unraid shares on the mirror during partnership onboarding.
|
|
# Safe to re-run — existing shares are never modified, only missing ones created.
|
|
#
|
|
# For each path in the owner's sync share lists (daily, weekly, critical,
|
|
# intermediate):
|
|
# - Extracts the top-level Unraid share name
|
|
# - Skips if the remote already has a .cfg for it
|
|
# - Uses the local share .cfg as a template: substitutes the remote's detected
|
|
# appdata pool, clears disk include/exclude (disk layouts differ per server)
|
|
# - Writes the .cfg to remote /boot/config/shares/ and mkdir -p the directory
|
|
# - For sub-paths (e.g. appdata-Fallback/Critical-Data), ensures the subdir
|
|
# exists after the top-level share is in place
|
|
#
|
|
# Pool detection: reads the remote's appdata.cfg to find its cache pool name,
|
|
# so appdata-type shares land on the right pool without hardcoding.
|
|
#
|
|
# Media shares (shareUseCache=no in local .cfg) are created as array-only.
|
|
# Remote admin assigns disk sets from the Unraid UI after onboarding.
