vv_push_master_conf() in config.php: finds all remote HOST* entries, resolves Tailscale IPs, SCPs master.conf to each. rawconf.php calls it after a successful write when file=master.conf. Scheduler save button shows sync status: "✓ Saved · synced to HOST2" or "✓ Saved · push failed: HOST2" on error. Also fix path bug in partnership_transfer.sh — was SCPing to appdata root instead of Configurations/.

# ============================= Partnership Transfer ============================================
|
|
# ==============================================================================================
|
|
#
|
|
# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Transfers ownership from the current owner to the current mirror. After
|
|
# transfer the roles are swapped: what was the mirror becomes the new owner,
|
|
# and what was the owner becomes the new mirror.
|
|
#
|
|
# No containers are moved — only config and WebUI targets are updated. Both
|
|
# servers remain in the partnership; the sync direction reverses on the next
|
|
# fallback.sh / critical_sync_maintenance.sh cycle.
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL MODEL
|
|
# ==============================================================================================
|
|
#
|
|
# OWNER ONLY — mirror cannot run this script.
|
|
#
|
|
# Step 1: Health Verification — both servers pass N consecutive health checks
|
|
# Step 2: Pre-transfer Sync — final sync in current direction (owner → mirror)
|
|
# Step 3: Reconfigure WebUIs — new owner WebUIs → localhost
|
|
# new mirror WebUIs → new owner IP
|
|
# Step 4: Flip Ownership — update PARTNERSHIP_OWNER_HOST in master.conf
|
|
# on both servers
|
|
# Step 5: Write State — ACTIVE written locally and pushed to new mirror
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL SAFEGUARDS
|
|
# ==============================================================================================
|
|
#
|
|
# Owner-Only Enforcement
|
|
# The script reads MY_ID from detect_hosts() and exits immediately if it is
|
|
# not the current PARTNERSHIP_OWNER_HOST. The mirror cannot run a transfer.
|
|
#
|
|
# Explicit Confirmation String
|
|
# Requires the exact passphrase from PARTNERSHIP_TRANSFER_CONFIRM via
|
|
# --confirm=<value>. Without a matching string the transfer is cancelled
|
|
# before any steps execute. Prevents accidental ownership changes.
|
|
#
|
|
# Active Partnership Guard
|
|
# Reads the local state file and exits if the current state is INACTIVE.
|
|
# A transfer without an active partnership has no defined outcome.
|
|
#
|
|
# Dual Health Verification
|
|
# Both servers must pass PARTNERSHIP_TRANSFER_STRIKES consecutive health
|
|
# checks before proceeding. A single failure resets the strike counter.
|
|
# After PARTNERSHIP_TRANSFER_MAX_ATTEMPTS total attempts the transfer aborts.
|
|
#
|
|
# Pre-transfer Final Sync
|
|
# A full sync in the current direction (owner → mirror) runs immediately
|
|
# before roles flip. Ensures the mirror is current before it becomes the owner.

# PARTNERSHIP_TRANSFER_STRIKES
