Turn the single-replica jellyfin-ha app into a proper high-availability deployment so the fork's Redis-coordinated distributed transcoding and PostgreSQL main database can actually be exercised. - Replace the Deployment with a 2-replica StatefulSet for stable pod identity; set JELLYFIN_INSTANCE_ID from metadata.name (the fork's Redis transcode-lease owner id), add soft podAntiAffinity and a PDB minAvailable 1. - Move the main Jellyfin DB to PostgreSQL via a CloudNativePG trio (3-instance Cluster, PgBouncer Pooler, Ceph RGW barman backups) mirroring the litellm pattern; an init container writes database.xml selecting the fork's Jellyfin-PostgreSQL provider and the DSN is composed from the CNPG-generated app secret pointed at the pooler. - Share /config on an RWX cephfs PVC across replicas; keep /cache per-pod via a volumeClaimTemplate. - Fix the transcode mount to the fork's real path /config/transcodes on the RWX PVC (raid5) so a surviving pod can resume the segments of the pod it takes over. - Add Intel iGPU hardware transcoding via the gpu.intel.com/i915 device plugin resource plus render/video supplemental groups. - Switch the Service to sessionAffinity ClientIP to reduce transcode churn. - Disable UDP auto-discovery. Library scans still run on every replica; a single-scanner leader election is a planned follow-up.
