Adds the static PV/PVC trio for the new 10Ti "mediastore" CephFS subvolume
plus a bootstrap Job that seeds its directory tree. Purely additive: the
existing media-tv/media-movies volumes are untouched.
- add static PVs arrstack-mediastore, fafflix-mediastore, cheeztv-mediastore
all pinned to the same rootPath on cephfs_csi_ssd_ec_4_1
- add the matching RWX 10Ti PVCs, k8up-excluded, statically bound by
volumeName + storageClassName ""
- add mediastore-bootstrap, an ArgoCD Sync-hook Job that mkdir -p's
/{fafflix,cheeztv}/{tvseries,movies} and /nzbget/downloads/complete as
uid/gid 1000
- wire the new manifests into the arrstack, fafflix and cheeztv bases
