## Why The active-active arrstack deploy (#383) is stuck in-cluster: the app Deployments (sync-wave 0) can never become Healthy without their Postgres DB, so ArgoCD never advances to create the shared `arrstack-postgres` cluster (wave 1). Separately, `/config` is an immutable RWO cephrbd PVC, so 3 replicas fail with Multi-Attach. ## How - Order DB infra before the apps: `<app>-db` VaultStaticSecrets + backup ObjectStoreUser/Bucket at sync-wave -3, CNPG `Cluster` -2, `Database` CRDs -1; app Deployments stay at default 0. - Switch each app's `/config` to an emptyDir per-pod volume (library DB is in Postgres, config is env-driven; MediaCover regenerates). Old RWO config PVCs orphan. Validated with kustomize build (62 resources). arrproxy/nzbget untouched.

# Shared PostgreSQL backend for the -unkin2 fork sonarr/radarr/prowlarr, whose
|
|
# Npgsql/EF Core provider moves each *arr off SQLite into Postgres and makes the
|
|
# shared-nothing, active-active multi-replica deployment possible. One cluster,
|
|
# one throwaway initdb owner ("app"), and three managed login roles — one per
|
|
# app — each with its own per-app database (see database-*.yaml). Role passwords
|
|
# come from the VSO-synced <app>-db Secrets (vaultstaticsecret.yaml), so no
|
|
# credential is rendered into git.
